Saudi Arabians woke up over the weekend to a once-in-a-decade cabinet reshuffle. Octogenarian oil minister Ali al-Naimi, who has been in charge of the Kingdom’s energy policy since 1995, was replaced by Khaled al-Falih, who is to head the newly created Energy, Industry, and Natural Resources Ministry. Majed al-Qusaibi was named head of the newly created Commerce and Investment Ministry. Finally, Ahmed al-Kholifey was made governor of the Saudi Arabia’s Central Bank (SAMA). It may come as a surprise to many Saudis that the origin of this reshuffle—and indeed the Kingdom’s new economic direction—finds its impetus in a report by the global management consulting firm McKinsey & Company.

A man with a plan

Saudi Arabia has been struggling to deal with the impact of lower oil prices. After years of recording budget surpluses, the government has seen its budgetary deficit grow to 15 percent of GDP. Lower oil prices—coupled with tensions with regional rival Iran over Yemen, Syria, and Lebanon—have put the Kingdom’s finances under pressure. Since oil prices began to plummet, Saudi Arabia’s ever-ambitious Deputy Crown Prince Mohammed bin Salman has been spearheading an ambitious reform initiative that seeks to diversify the Kingdom’s economy away from oil. 

Dubbed “Saudi Arabia’s Vision 2030,” the prince says that the new economic blueprint will increase the role of the private sector from 40 percent to 60 percent, reduce unemployment from 11 percent to 7.6 percent, and grow non-oil income exponentially. This is to be financed by the partial privatization of the Kingdom’s oil behemoth, Aramco. 

The 2030 document outlines a number of significant reforms that seek to change not only the Saudi economy, but state-society relations more broadly, in a way that has been done since the Kingdom’s founding.

The 2030 document outlines a number of significant reforms that seek to change not only the Saudi economy, but state-society relations more broadly, in a way that hasn't been done since the Kingdom’s founding. The prince’s vision seems to have been inspired by a report issued by the McKinsey Global Institute in December 2015 titled “Moving Saudi Arabia’s Economy Beyond Oil.” The vision and the report have similar policy prescriptions for diversifying the Kingdom’s economy away from oil. 

Such similarities highlight the influence of consultancies on policymaking in the Kingdom. Indeed, Bloomberg news reported that consultancies are set to earn 12 percent more in commissions in Saudi Arabia this year, the fastest growth amongst the world’s advisory markets. In a wide-ranging interview with The Economist in January, Prince Mohammed himself said that “McKinsey participates with us in many studies.” According to the Financial Times, Saudi businessmen have sarcastically dubbed the Ministry of Planning as the “McKinsey Ministry.”

McKinsey’s key report, full with glossy illustrations, contains consultant buzzwords (“transformation,” “efficiency,” and “synergies”) that would make Marty Kaan in Showtimes’s House of Lies proud. It’s by no means novel for consultants to advise governments in the region and across the world, and indeed the report does outline an ambitious blueprint for the Kingdom’s economic transformation and diversification away from oil. 

Will the public buy it?

But in a glaring omission, the report does not adequately explain how the Saudi government will be able to change the mindset of everyday Saudi Arabia citizens, who have long been accustomed to state largesse that included fuel subsidies, loans, free land, and public sector jobs. 

This is the key issue. The reform plans sound promising, and will indeed make headway in weaning the Kingdom off its oil “addiction” (as the prince himself put it). But how will everyday citizens react to the reforms? The Saudi government will be asking more of its citizens—will the citizens in turn ask for more accountability and representation? Since January, the prices of gasoline, electricity, and water have gone up. There was a public outcry against higher utility prices, which lead King Salman to fire the water minister to absorb the public’s anger. 

Such discontent is the harbinger of things to come. The coming months and years will show how Saudi leadership implements much needed economic reforms without alienating its population. While the outcome is uncertain, one thing is: consultants will continue to flock to Saudi Arabia to work on the “mother of all transformation projects.”

Rooftop solar is booming in U.S. cities.

One of the most exciting infrastructure developments within metropolitan America, the installation of over a million solar photovoltaic (PV) systems in recent years, represents nothing less than a breakthrough for urban sustainability — and the climate.

Prices for solar panels have fallen dramatically. Residential solar installations surged by 66 percent between 2014 and 2015 helping to ensure that solar accounted for 30 percent of all new U.S. electric generating capacity. And for that matter, recent analyses conclude that the cost of residential solar is often comparable to the average price of power on the utility grid, a threshold known as grid parity.

So, what’s not to like? Rooftop solar is a total winner, right?

Well, not quite: The spread of rooftop solar has raised tricky issues for utilities and the public utilities commissions (PUCs) that regulate them. 

Specifically, the proliferation of rooftop solar installations is challenging the traditional utility business model by altering the relationship of household and utility—and not just by reducing electricity sales. In this respect, the solar boom has prompted significant debates in states like New York and California about the best rates and policies to ensure that state utility rules and rates provide a way for distributed solar to flourish even as utilities are rewarded for meeting customer demands. Increasingly, this ferment is leading to thoughtful dialogues aimed at devising new forms of policy and rate design that can—as in New York—encourage distributed energy resources (DERs) while allowing for distribution utilities to adapt to the new era.

However, in some states, the ferment has prompted a cruder set of backlashes. Most pointedly, some utilities contend that the “net-metering” fees paid to homeowners with rooftop installations for excess solar power they send back to the grid unfairly transfer costs to the utilities and their non-solar customers.

And so in a number of states, utility interests have sought to persuade state regulators to roll back net-metering provisions, arguing they are a net cost to the overall electricity system.  Most glaringly, the local utility in Nevada successfully wielded the cost-shift theory last winter to get the Nevada Public Utilities Commission to drastically curtail the state’s net-metering payments, prompting Solar City, Sunrun, and Vivint Solar—the state’s three largest providers of rooftop panels—to leave the Nevada market entirely. The result: New residential solar installation permits plunged 92 percent in Nevada in the first quarter of 2016.

All of which highlights a burning question for the present and future of rooftop solar: Does net metering really represent a net cost shift from solar-owning households to others? Or does it in fact contribute net benefits to the grid, utilities, and other ratepayer groups when all costs and benefits are factored in? As to the answer, it’s getting clearer (even if it’s not unanimous). Net metering — contra the Nevada decision — frequently benefits all ratepayers when all costs and benefits are accounted for, which is a finding state public utility commissions, or PUCs, need to take seriously as the fight over net metering rages in states like Arizona, California, and Nevada.  Regulators everywhere need to put in place processes that fairly consider the full range of benefits (as well as costs) of net metering as well as other policies as they set and update the policies, regulations, and tariffs that will play a critical role in determining the extent to which the distributed solar industry continues to grow.

Fortunately, such cost-benefit analyses have become an important feature of state rate-setting processes and offer important guidance to states like Nevada.  So what does the accumulating national literature on costs and benefits of net metering say?  Increasingly it concludes— whether conducted by PUCs, national labs, or academics — that the economic benefits of net metering actually outweigh the costs and impose no significant cost increase for non-solar customers.  Far from a net cost, net metering is in most cases a net benefit—for the utility and for non-solar rate-payers.

Of course, there are legitimate cost-recovery issues associated with net metering, and they vary from market to market. Moreover, getting to a good rate design, which is essential for both utility revenues and the growth of distributed generation, is undeniably complicated.  If rates go too far in the direction of “volumetric energy charges”—charging customers based on energy use—utilities could have trouble recovering costs when distributed energy sources reach higher levels of penetration. On the other hand, if rates lean more towards fixed charges—not dependent on usage—it may reduce incentives for customers to consider solar and other distributed generation technologies.  

Moreover, cost-benefit assessments can vary due to differences in valuation approach and methodology, leading to inconsistent outcomes. For instance, a Louisiana Public Utility Commission study last year found that that state’s net-metering customers do not pay the full cost of service and are subsidized by other ratepayers. How that squares with other states’ analyses is hard to parse.

Nevertheless, by the end of 2015, regulators in at least 10 states had conducted studies to develop methodologies to value distributed generation and net metering, while other states conducted less formal inquiries, ranging from direct rate design or net-metering policy changes to general education of decisionmakers and the public. And there is a degree of consensus.  What do the commission-sponsored analyses show? A growing number show that net metering benefits all utility customers:

• In 2013 Vermont’s Public Service Department conducted a study that concluded that “net-metered systems do not impose a significant net cost to ratepayers who are not net-metering participants.” The legislatively mandated analysis deemed the policy a successful component of the state’s overall energy strategy that is cost effectively advancing Vermont’s renewable energy goals.

• In 2014 a study commissioned by the Nevada Public Utility Commission itself concluded that net metering provided $36 million in benefits to all NV Energy customers, confirming that solar energy can provide cost savings for both solar and non-solar customers alike. What’s more, solar installations will make fewer costly grid upgrades necessary, leading to additional savings. The study estimated a net benefit of $166 million over the lifetime of solar systems installed through 2016. Furthermore, due to changes to utility incentives and net-metering policies in Nevada starting in 2014, solar customers would not be significantly shifting costs to other ratepayers.

• A 2014 study commissioned by the Mississippi Public Services Commission concluded that the benefits of implementing net metering for solar PV in Mississippi outweigh the costs in all but one scenario. The study found that distributed solar can help avoid significant infrastructure investments, take pressure off the state's oil and gas generation at peak demand times, and lower rates. (However, the study also warned that increased penetrations of distributed solar could lead to lower revenues for utilities and suggested that the state investigate Value of Solar Tariffs, or VOST, and other alternative valuations to calculate the true cost of solar.)

• In 2014 Minnesota’s Public Utility Commission approved a first-ever statewide “value of solar” methodology which affirmed that distributed solar generation is worth more than its retail price and concluded that net metering undervalues rooftop solar. The “value of solar” methodology is designed to capture the societal value of PV-generated electricity. The PUC found that the value of solar was at 14.5 cents per kilowatt hour (kWh)—which was 3 to 3.5 cents more per kilowatt than Xcel's retail rates—when other metrics such as the social cost of carbon, the avoided construction of new power stations, and the displacement of more expensive power sources were factored in.

• Another study commissioned by the Maine Public Utility Commission in 2015 put a value of $0.33 per kWh on energy generated by distributed solar, compared to the average retail price of $0.13 per kWh — the rate at which electricity is sold to residential customers as well as the rate at which distributed solar is compensated. The study concludes that solar power provides a substantial public benefit because it reduces electricity prices due to the displacement of more expensive power sources, reduces air and climate pollution, reduces costs for the electric grid system, reduces the need to build more power plants to meet peak demand, stabilizes prices, and promotes energy security. These avoided costs represent a net benefit for non-solar ratepayers.

These generally positive PUC conclusions about the benefits of net metering have been supported by research done by a national lab and several think tanks. Important lab research has examined how substantially higher adoption of distributed resources might look.

In a forward-looking analysis of the financial impacts of net-metered energy on utilities and ratepayers, Lawrence Berkeley National Lab found that while high use of net-metered solar generation may decrease utility shareholders' earnings, it will have a "relatively modest" impact on ratepayers. The report examined solar penetration levels that are "substantially higher than [those that] exist today" — 10 percent compared to today's 0.2 percent — and concluded that “even at penetration levels significantly higher than today, the impacts of customer-sited PV on average retail rates may be relatively modest." The report further said that utilities and regulators "may have sufficient time to address concerns about the rate impacts of PV in a measured and deliberate manner"

Similarly, a growing number of academic and think tank studies have found that solar energy is being undervalued and that it delivers benefits far beyond what solar customers are receiving in net-metering credits:

• For instance, a review of 11 net metering studies by Environment America Research and Policy Center has found that distributed solar offers net benefits to the entire electric grid through reduced capital investment costs, avoided energy costs, and reduced environmental compliance costs. Eight of the 11 studies found the value of solar energy to be higher than the average local residential retail electricity rate: The median value of solar power across all 11 studies was nearly 17 cents per unit, compared to the nation’s average retail electricity rate of about 12 cents per unit.

• A 2015 cost-benefit study of net metering in Missouri by the Missouri Energy Initiative found that even accounting for increased utility administrative costs and the shifting of some fixed expenses, net metering is a net benefit for all customers regardless of whether they have rooftop solar. The study used values for two kinds of costs and two benefits and concluded that net metering’s “net effect” is positive. The typical solar owner pays only 20 percent less in fixed grid costs and costs the utility an estimated $187 per interconnection. Meanwhile, solar owners benefit the system through reduced emissions and energy costs.

• Likewise, a study by Acadia Center found the value of solar to exceed 22 cents per kWh of value for Massachusetts ratepayers through reduced energy and infrastructure costs, lower fuel prices, and lowering the cost of compliance with the Commonwealth's greenhouse gas requirements. This value was estimated to exceed the retail rate provided through net metering.

• In yet another study, researchers at the University at Albany, George Washington University, and Clean Power Research have found that solar installations in New York deliver between 15 and 40 cents per kWh to ratepayers. The study noted that these numbers provide economic justification for the existence of incentives that transfer value from those who benefit from solar electric generation to those who invest in solar electric generation.

In short, while the conclusions vary, a significant body of cost-benefit research conducted by PUCs, consultants, and research organizations provides substantial evidence that net metering is more often than not a net benefit to the grid and all ratepayers.

As to the takeaways, they are quite clear: Regulators and utilities need to engage in a broader and more honest conversation about how to integrate distributed-generation technologies into the grid nationwide, with an eye toward instituting a fair utility-cost recovery strategy that does not pose significant challenges to solar adoption.

From the state PUCs’ perspective, until broad changes are made to the increasingly outdated and ineffective standard utility business model, which is built largely around selling increasing amounts of electricity, net-metering policies should be viewed as an important tool for encouraging the integration of renewable energy into states’ energy portfolios as part of the transition beyond fossil fuels. To that end, progressive regulators should explore and implement reforms that arrive at more beneficial and equitable rate designs that do not prevent solar expansion in their states. The following reforms range from the simplest to the hardest:

• Adopt a rigorous and transparent methodology for identifying, assessing, and quantifying the full range of benefits and costs of distributed generation technologies. While it is not always possible to quantify or assess sources of benefits and costs comprehensively, PUCs must ensure that all cost-benefit studies explicitly decide how to account for each source of value and state which ones are included and which are not. Currently methodological differences in evaluating the full value of distributed generation technologies make comparisons challenging. States start from different sets of questions and assumptions and use different data. For instance, while there is consensus on the basic approach to energy value estimation (avoided energy and energy losses via the transmission and distribution system), differences arise in calculating other costs and benefits, especially unmonetized values such as financial risks, environmental benefits, and social values. In this regard, the Interstate Renewable Energy Council’s “A Regulator’s Guidebook: Calculating the Benefits and Costs of Distributed Solar Generation” and the National Renewable Energy Laboratory’s “Methods for Analyzing the Benefits and Costs of Distributed Photovoltaic Generation to the U.S. Electric Utility System” represent helpful resources for identifying norms in the selection of categories, definitions, and  methodologies to measure various benefits and costs.

• Undertake and implement a rigorous, transparent, and precise “value of solar” analytic and rate-setting approach that would compensate rooftop solar customers based on the benefit that they provide to the grid. Seen as an alternative to ‘traditional’ net-metering rate design, a “value of solar” approach would credit solar owners for (1) avoiding the purchase of energy from other, polluting sources; (2) avoiding the need to build additional power plant capacity to meet peak energy needs; (3) providing energy for decades at a fixed prices; and (4) reducing wear and tear on the electric grid. While calculating the “value of solar” is very complex and highly location-dependent, ultimately PUCs may want to head toward an approach that accurately reflects all benefits and costs from all energy sources. Value of solar tariffs are being used in Austin, Texas (active use) and Minnesota (under development).

• Implement a well-designed decoupling mechanism that will encourage utilities to promote energy efficiency and distributed generation technologies like solar PV, without seeing them as an automatic threat to their revenues. As of January 2016, 15 states have implemented electric decoupling and eight more are considering it. Not surprisingly, it is states that have not decoupled electricity (such as Nevada) that are fighting net metering the hardest. Typically, decoupling has been used as a mechanism to encourage regulated utilities to promote energy efficiency for their customers. However, it can also be used as a tool to incentivize net metering by breaking the link between utility profits and utility sales and encouraging maximum solar penetration. Advocates of decoupling note that it is even more effective when paired with time-of-use pricing and minimum monthly billing.

• Move towards a rate design structure that can meet the needs of a distributed resource future. A sizable disconnect is opening between the rapidly evolving new world of distributed energy technologies and an old world of electricity pricing. In this new world, bundled, block, “volumetric” pricing—the most common rate structure for both residential and small commercial customers—can no longer meet the needs of all stakeholders. The changing grid calls, instead, for new rate structures that respond better to the deployment of new grid technologies and the proliferation of myriad distributed energy resources, whether solar, geothermal, or other.  A more sophisticated rate design structure, in this regard, would take into consideration three things: (1) the unbundling of rates to specifically price energy, capacity, ancillary services,  and so on; (2) moving from volumetric bloc rates to pricing structures that recognize the  variable time-based value of electricity generation and consumption (moving beyond just peak versus off-peak pricing to  fully real-time pricing); and (3) moving from pricing that treats all customers equally to a pricing structure that more accurately compensates for unique, location-specific and technology specific values.

• Move towards a performance-based utility rate-making model for the modern era. Performance based regulation (PBR) is a different way of structuring utility regulation designed to align a utility’s financial success with its ability to deliver what customers and society want. Moving to a model that pays the utility based on whether it achieves quantitatively defined outcomes (like system resilience, affordability, or distributed generation integration) can make it profitable for them to pursue optimal grid solutions to meet those outcomes. The new business model would require the PUC and utilities to make a number of changes, including overhauling the regulatory framework, removing utility incentives for increasing capital assets and kilowatt hours sold, and replacing those incentives with a new set of performance standard metrics such as reliability, safety, and demand-side management. New York’s Reforming the Energy Vision  proceeding is the most high-profile attempt in the country to implement a PBR model.

Options also exist for utilities to address the challenges posed by net metering:

• Utilities, most notably, have the opportunity to adjust their existing business models by themselves owning and operating distributed PV assets (though not to the exclusion of other providers).  On this front, utilities could move to assemble distributed generation systems, such as for rooftop solar, and sell or lease them to homeowners. In this regard, utilities have an advantage over third-party installers currently dominating the residential rooftop solar industry due to their proprietary system knowledge, brand recognition, and an existing relationship with their customers. Utilities in several states such as Arizona, California, and New York are investigating or have already invested in the opportunity.

• Furthermore, utilities can also push the envelope on grid modernization by investing in a more digital and distributed power grid that enables interaction with thousands of distributed energy resources and devices.

Ultimately, distributed solar is here to stay at increasing scale, and so state policies to support it have entered an important new transitional phase. More and more states will now likely move to update their net-metering policies as the cost of solar continues to drop and more homeowners opt to install solar panels on their homes.

As they do that, states need to rigorously and fairly evaluate the costs and benefits posed by net metering, grid fees, and other policies to shape a smart, progressive regulatory system that works for all of the stakeholders touched by distributed solar.

Utilities should have a shot at fair revenues and adequate ratepayers. Solar customers and providers have a right to cost-effective, reliable access to the grid. And the broader public should be able to expect a continued solar power boom in U.S. regions as well as accelerated decarbonization of state economies. All of which matters intensely. As observes the North Carolina Clean Energy Technology Center and Meister Consultants Group: “How key state policies and rates are adapted will play a significant role in determining the extent to which the [solar PV] industry will continue to grow and in what markets.”

On Tuesday, May 24, Nigerian Central Bank Governor Godwin Emefiele announced that the country will adopt a more flexible foreign exchange rate system in the near future. This move signals a major policy shift by Emefiele and President Muhammadu Buhari, who had until this point opposed calls to let the naira weaken. Many international oil-related currencies have depreciated against the dollar as oil prices began their decline in 2014. Nigeria, however, has held the naira at a peg of 197-199 per U.S. dollar since March 2015, depleting foreign reserves and deterring investors, who remain concerned about the repercussions of a potential naira devaluation. Following the announcement, Nigerian stocks jumped to a five-month high and bond prices rose in anticipation that a new flexible exchange rate regime would increase the supply of dollars and help attract foreign investors.

For now it remains unclear exactly what a more flexible system will entail for Nigeria, however, some experts suggest that the Central Bank may introduce a dual-rate system, which allows select importers in strategic industries to access foreign currency at the current fixed rate, while more generally foreign currency will be available at a weaker, market-related level. This new regime raises a number of questions, including how it will be governed and who will have access to foreign currency (and at what rate). On Wednesday, Nigeria’s parliament requested a briefing soon from Emefiele and Finance Minister Kemi Adeosun to provide additional clarity on the new system, although the date for such a meeting has not yet been set.

Earlier this month, Kenya announced plans to close the Dadaab refugee camp, located in northeast Kenya, amid security concerns. The move to close the camp has been widely criticized by international actors. United States State Department Press Relations Director Elizabeth Trudeau urged Kenya to “uphold its international obligations and not forcibly repatriate refugees.” The United Nations High Commissioner for Refugees stated that the closure of the refugee camp would have “devastating consequences.” Despite these concerns, this week, at the World Humanitarian Summit, Kenya stated that it will not go back on its decision and confirmed the closure of the refugee camps within a six-month period.

The camp houses 330,000 refugees, a majority of whom fled from conflict in their home country of Somalia. Kenya insists that the camp poses a threat to its national security, as it believes the camp is used to host and train extremists from Somalia’s Islamist group al-Shabab. Kenya also argued that the developed world, notably the United Kingdom, should host its fair share of African refugees. This is not the first time Kenya has threatened to close the refugee camp. After the Garissa University attacks last April, Kenya voiced its decision to close the refugee camps, although it did not follow through with the plan.

From May 23-27, Lusaka, Zambia hosted 5,000 delegates and participants for the 2016 Annual Meetings of the African Development Bank (AfDB), with the theme, “Energy and Climate Change.” Held in the wake of December’s COP21 climate agreement and in line with Sustainable Development Goals 7 (ensure access to affordable, reliable, sustainable and modern energy for all) and 13 (take urgent action to combat climate change and its impacts), the theme was timely and, as many speakers emphasized, urgent. Around 645 million people in Africa have no access to electricity, and only 16 percent are connected to an energy source. To that end, AfDB President Akinwumi Adesina outlined the bank’s ambitious aim: “Our goal is clear: universal access to energy for Africa within 10 years; Expand grid power by 160 gigawatts; Connect 130 million persons to grid power; Connect 75 million persons to off grid systems; And provide access to 150 million households to clean cooking energy."

As part of a push to transform Africa’s energy needs and uses, Rwandan President Paul Kagame joined Kenyan President Uhuru Kenyatta on a panel to support the AfDB’s “New Deal on Energy” that aims to deliver electricity to all Africans by 2025. Kenyatta specifically touted the potential of geothermal energy sources. Now, 40 percent of Kenya's power needs come from geothermal energy sources, he said, but there is still room for improvement—private businesses, which make up 30 percent of Kenya’s on-grid energy needs, have not made the switch yet.

As part of the meetings, the AfDB, the Organization for Economic Cooperation and Development (OECD), and United Nations Development Program (UNDP) also launched their annual African Economic Outlook, with the theme “Sustainable Cities and Structural Transformation.” In general, the report’s authors predict that the continent will maintain an average growth of 3.7 percent in 2016 before increasing to 4.5 percent in 2017, assuming commodity prices recover and the global economy improves.  However, the focus was on this year’s theme: urbanization. The authors provide an overview of urbanization trends and highlight that successful urban planning can discourage pollution and waste, slow climate change, support better social safety nets, enhance service delivery, and attract investment, among other benefits.

On Friday, June 3, S&P Global Ratings announced that it would not downgrade South Africa’s credit rating to junk, letting South Africa breathe a sigh of relief. The outlook, however, remained negative. While some experts were confident that the rating would not be cut, most continued to warn that future economic or political turmoil could spark a downgrade later this year. The South African Treasury agreed, but remained positive releasing a statement saying:

Government is aware that the next six months are critical and there is a need to step up the implementation [of measures to boost the economy] … The benefit of this decision is that South Africa is given more time to demonstrate further concrete implementation of reforms that are underway.

South Africa, whose current rating stands at BBB- (one level above junk), has been facing weak economic growth—at 1 percent—over past months. The International Monetary Fund has given a 2016 growth forecast of 0.6 percent. Many feared that a downgrade could have pushed the country into a recession. Borrowing by the government would have also become more expensive, especially as it tackles a 3.2 percent of GDP budget deficit for the 2016-2017 fiscal year.

Other credit ratings agencies also are concerned with South Africa’s economic performance. Last month, Moody’s Investors Service ranked the country two levels above junk but on review for a potential downgrade, while Fitch Ratings is reviewing its current stable outlook and BBB- rating.

This week, the Extraordinary African Chambers—located in Dakar and established in collaboration with the African Union—sentenced former Chadian President Hissène Habré to life in prison. Habré seized power in 1982, overthrowing then President Goukouni Oueddei. He fled to Senegal in 1990 after being ousted by current Chadian President Idriss Deby. After he fled to Senegal, the African Union called on Senegal to prosecute Habré. In 2013, the Extraordinary African Chamber was created with the sole aim to prosecute Habré. The Habré trial is the first trial of a former African head of state in another African country.

Habré faced a long list of charges including crimes against humanity, rape, sexual slavery, and ordering killings while in power. According to Chad’s Truth Commission,  Habré’s government murdered 40,000 people during his eight-year reign. At the trial, 102 witnesses, victims, and experts testified to the horrifying nature of Habré’s rule. His reign of terror was largely enabled by Western countries, notably France and the United States. In fact, on Sunday, U.S. Secretary of State John Kerry admitted to his country’s involvement in enabling of Habré’s crimes. He was provided with weapons and money in order to assist in the fight against former Libyan leader Moammar Gadhafi. Said resources were then used against Chadian citizens.

Also this week, Simone Gbagbo, former Ivorian first lady, is being tried in Côte d’Ivoire’s highest court— la Cour d’Assises—for crimes against humanity. She also faces similar charges at the International Criminal Court though the Ivoirian authorities have not reacted to the arrest warrant issued in 2012. In March 2015, Simone Gbabgo was sentenced to 20 years in jail for undermining state security as she was found guilty of distributing arms to pro-Laurent Gbagbo militia during the 2010 post-electoral violence that left 3000 dead. Her husband is currently on trial in The Hague for the atrocities committed in the 2010 post-election period.

On Monday, May 30, South African chemical and energy company Sasol Ltd announced that Mozambique’s ongoing debt crisis and continuing low global gas prices would not slow down its Mozambican gas project. The company expressed confidence in a $1.4 billion processing facility upgrade stating that the costs will be made up through future gas revenues. In explaining Sasol’s decision to increase the capacity of its facility by 8 percent, John Sichinga, senior vice president of Sasol’s exploration and production unit, stated, “There is no shortage of demand … There’s a power pool and all the countries of the region are short of power.” In addition, last week, Sasol began drilling the first of 12 new planned wells in the country.

On the other hand, on Monday The Wall Street Journal published an article examining how these low gas prices are stagnating much-hoped-for growth in East African countries like Tanzania and Mozambique as low prices prevent oil companies from truly getting started. Now, firms that flocked to promising areas of growth around these industries are downsizing or moving out, rents are dropping, and layoffs are frequent. Sasol’s Sichinga remains positive, though, emphasizing, "We are in Mozambique for the long haul. We will ride the waves, the downturns, and the upturns."

The debate surrounding net energy metering (NEM) and the appropriate way to reform this policy is under scrutiny in many U.S. states. This is highly warranted since NEM policies do indeed need reforming because NEM often results in subsidies to private (rooftop) solar owners and leasing companies. These subsidies are then “paid for” by non-NEM customers (customers without private rooftop solar installations). The fundamental source of the NEM subsidy is the failure of NEM customers (customers with private rooftop solar installations) to pay fully for the grid services that they use 24/7. These subsidies are well-documented and underpin much of the regulatory reform efforts underway across the United States.[1]

In a recent Brookings paper, “Rooftop solar: Net metering is a net benefit,” Mark Muro and Devashree Saha contend that net metering is a net benefit for non-NEM customers.[2] I fundamentally disagree with their findings, and argue that NEM is not a net benefit; it is, in fact, a tariff that much of the time results in a subsidy to NEM customers and a cost shift onto non-NEM customers. As Executive Director of the Institute for Electric Innovation, a non-lobbying organization focused on trends in the electric power industry, I have followed this debate and written about it for several years.

Much of the talk about NEM focuses too often on the “value” of the energy that is sold back to the grid by a NEM customer. In reality, the amount of energy sold back to the grid is relatively small. The real issue is the failure of NEM customers to pay fully for the grid services that they use while connected to the grid 24/7, as shown in Figure 1.[3] Customers need to constantly use the grid to balance supply and demand throughout the day, and the cost of these grid services can be sizeable. In fact, for a typical residential customer in the United States with an average electricity bill of $110 per month, the actual cost of grid services can range from $45 to $70 per month–however, the customer doesn’t see that charge.[4] That means, in the extreme, if a customer’s energy use “nets” to zero in a given month because the customer’s private solar system produced exactly what the customer consumed, that customer would pay $0 even though that customer is connected to the local electric company’s distribution grid and is utilizing grid services on a continuous around-the-clock basis.[5]

Although exactly netting to zero energy in a month is highly unlikely, this example demonstrates the point that the customer would pay nothing, despite using grid services at a cost ranging from $45 to $70 per month. Over the course of one year, this customer could receive a subsidy resulting from NEM of between $540 and $840. Over the life of a private rooftop solar system, which ranges from 20 to 25 years, this is a significant subsidy resulting from NEM.

Granted, this is an extreme example, and most NEM customers will pay for some portion of grid services. However, the fundamental source of the NEM subsidy is the failure of NEM customers to pay fully for the grid services that they use 24/7, and the cost of these services can be quite substantial. When a NEM customer doesn’t pay for the grid, the cost is shifted onto non-NEM customers.[6] It is a zero-sum game; plain and simple. This is the elephant in the room.

This issue was directly addressed by Austin Energy when the company implemented a “buy-sell” arrangement for the private rooftop solar customers in its service territory. The rationale for the buy-sell approach is that the customer buys all of the energy that is consumed on-site through the electric company’s retail tariff and sells all of the energy produced by their private rooftop solar system at the electric company’s avoided cost. This addresses the “elephant in the room” because, by buying all energy consumed at the retail tariff, the customer does pay for grid services that are largely captured through the retail tariff. It is an unfortunate fact that under ratemaking practices today in the United States, the majority of fixed costs (i.e., grid and other costs) are captured through a volumetric charge.

Hence, I fundamentally disagree with the Muro/Saha paper–NEM does need to be reformed. NEM is not a net benefit; it is a tariff that the much of the time results in a cost shift onto non-NEM customers. One of the first studies to quantify the magnitude of the NEM subsidy was conducted by Energy+Environmental Economics (E3) for the California Public Utilities Commission (CPUC) in 2013. There was no mention of this analysis for the CPUC in the Muro/Saha paper. The E3 study estimated that NEM would result in a cost shift of $1.1 billion annually by 2020 from NEM to non-NEM customers if current NEM policies were not reformed in California.[7] A cost shift of this magnitude–paid for by non-NEM customers–was unacceptable to California regulators. As a result, California regulators set to work to reform rates in their state; many other states followed suit and conducted similar investigations of the magnitude of the NEM subsidy.

In reviewing NEM studies, Muro and Saha chose to focus on a handful of studies that show that net metering results in a benefit to all customers. In this small group of NEM studies, they included a study that E3 conducted for the Nevada Public Utilities Commission (PUC) in 2014–perhaps the most well-known and cited of the five studies included in the Muro/Saha paper. Very soon after the E3 Nevada study was published, the cost assumptions for the base-case scenario which showed a net benefit of $36 million to non-NEM customers (assuming $100 per MWh for utility-scale solar) were found to be incorrect, completely reversing the conclusion. The $36 million benefit associated with NEM for private rooftop solar turned into a $222 million cost to non-NEM customers when utility-scale solar was priced at $80 per MWh.[8] Today, based on the two most recent utility-scale contracts approved by the Nevada PUC, utility-scale solar has an average lifetime (i.e., levelized) cost of $50 per MWh, meaning that the NEM cost shift would be far greater today. In February 2016, the Nevada PUC stated that “the E3 study is already outdated and irrelevant to the discussion of costs and benefits of NEM in Nevada…”[9] Hence, because the E3 study for the Nevada PUC that the Muro/Saha paper included has been declared outdated and irrelevant to the discussion and because costs for utility-scale solar have declined significantly, that study does not show that NEM provides a net benefit.

No doubt there is an intense debate underway about NEM for private rooftop solar, and much has changed in the past two years in terms of both NEM policies and the growth of private solar projects:

• First, several state regulatory commissions now recognize that the NEM cost shift is both real and sizeable and that all customers who use the grid, including NEM customers, need to pay for the cost of the grid. As a result, many electric companies have proposed and state regulatory commissions have approved increases in monthly fixed charges over the past few years; this partially addresses the issue of NEM customers paying for the cost of the grid services that they use.
• Second and related, getting the pricing right for distributed energy resources of all types is important because we expect those resources to grow significantly in the future. Work is underway in this area and it is one focus of the New York Reforming the Energy Vision proceeding; but there is still much to be done.

By focusing on a select group of studies that show that NEM benefits all customers (as stated by the authors); by excluding the E3 study for the CPUC which was fundamental to the NEM cost shift debate; and by not providing an update on the NEM debate today, I believe that the Muro/Saha paper is misleading.

In the second part of their paper, Muro and Saha suggest some helpful regulatory reforms such as moving toward rate designs that “can meet the needs of a distributed resource future” and moving “toward performance-based rate-making (PBR).” Some electric companies have already implemented PBR or some type of formula rate and PBR is under discussion in several states.[10] Lawrence Berkeley National Labs is looking closely at this and related issues in its Future Electric Utility Regulation series of reports currently underway.[11]

Mura and Saha also suggest decoupling as a way forward–I disagree. In my view, decoupling is a not solution for private rooftop solar. Revenue decoupling is currently used to true-up revenues that would otherwise be lost due to declining electricity sales resulting from electric company investments in energy efficiency (EE). Decoupling explicitly shifts costs from participating EE customers to non-participating EE customers causing the same cost-shifting problem that is created by NEM. However, a fundamental difference is that the magnitude of the cost shifting onto non-NEM customers is on a much larger scale than the cost shifting due to EE. A recent study revealed that decoupling rate adjustments for EE are quite small–about two to three percent of the retail rate.^[12] In contrast, as described earlier in this paper, a NEM customer could shift a significant cost onto non-NEM customers (and the NEM cost shifting is essentially invisible to customers, which is one reason that NEM customers do not believe they are subsidized).[13]

Finally, Muro and Saha suggest that electric companies should invest in a more digital and distributed power grid. In fact, electric companies across the United States are doing just that. In 2015, electric companies invested $20 billion in the distribution system alone and this is expected to continue. Over the past five to six years, electric companies invested in the deployment of nearly 65 million digital smart meters to about 50 percent of U.S. households. In addition, electric companies are investing in thousands of devices to make the power grid smarter and more state-aware. Today, in states such as California, Hawaii, and Arizona, electric companies are investing to enable and integrate the distributed energy resources that are growing exponentially. And, in some states–where regulation allows–electric companies are offering rooftop solar or solar subscriptions to their customers.

No doubt, the electric power industry is undergoing a period of profound transformation–our power generation resource mix is getting cleaner and more distributed; the energy grid is becoming more digital; and customers have different expectations.[14]

Collaboration, good public policy, and appropriate regulatory policies are critical to a successful transformation of the power sector. In the context of this paper, this means reforming NEM so that private rooftop solar customers who use the energy grid pay for the grid. One straightforward approach is to require NEM customers to pay a higher monthly fixed charge thereby reducing the cost shift.[15] Ultimately the challenge is to make the transition of the electric power industry–including the significant growth in private rooftop solar and other distributed energy resources–affordable to all customers.

Renewable energy is an important source to tackle against climate change, as the latest IPCC report has pointed out. However, due to the existence of multiple market failures such as negative externalities of fossil fuels and knowledge spillovers of new technology, government subsidies are still needed to develop renewable energy, such as solar photovoltaic (PV) cells. In the United States, there have been various forms of subsidies for PV, varying from the federal level to the state level, and from the city level to the utility level. California, as the pioneer of solar PV development, has put forward the biggest state-level subsidy program for PV, the California Solar Initiative (CSI). The CSI has planned to spend around $2.2 Billion in 2007–2016 to install roughly 2 GW PV capacity, with the average subsidy level as high as $1.1/W. How to evaluate the cost-effectiveness and incentive pass-through of this program are the two major research questions we are pursing.

Our cost-effectiveness analysis is based on a constrained optimization model that we developed, where the objective is to install as much PV capacity as possible under a fixed budget constraint. Both the analytical and computational results suggest that due to a strong peer effect and the learning-by-doing effect, one can shift subsides from later periods to early periods so that the final PV installed capacity can be increased by 8.1% (or 32 MW). However, if the decision-maker has other policy objectives or constraints in mind, such as maintaining the policy certainty, then, the optimally calculated subsidy policy would look like the CSI.

As to the incentive pass-through question, we took a structural approach and in addition used the method of regression discontinuity (RD). While in general, the incentive pass-through rate depends on the curvature of the demand and supply curve and the level of market competition, our two estimations indicate that the incentive pass-through for the CSI program is almost complete. In other words, almost all of the incentive has been enjoyed by the customer, and the PV installers did not retain much. Based on the RD design, we observe that PV installers tend to consider the CSI incentive as exogenous to their pricing decision.

The relative good performance of the CSI in terms of both the cost-effectiveness and the incentive pass-through aspect are tightly related to its policy design and program management. International speaking, the biggest challenge for the design of any PV subsidy program is the quick running out of the budget, and in the end, it looks like customers are rushing for the subsidy. Such rushing behavior is a clear indication of higher-than-needed incentive levels. Due to the policy rigidity and rapid PV technological change, the PV subsidy policy may lag behind the PV cost decline; and as a result, rational customers could rush for any unnecessarily high subsidy.

Due to the high uncertainty and unpredictability of future PV costs, the CSI put forward a new design that links the incentive level change and the installed capacity goal fulfillment. Specifically, the CSI has designed nine steps to achieve its policy goal; at each step, there is a PV capacity goal that corresponds to an incentive level. Once the capacity goal is finished, the incentive level will decrease to the next lower level. Furthermore, to maintain the policy certainty, the CSI regulated that every step-wise change in the incentive level should not be higher than $0.45/W, nor smaller than $0.05/W, together with other three constraints.

A good subsidy policy not only requires flexible policy design to respond to fast-changing environment, but also demands an efficient program management system, digitalized if possible. For the CSI, the authority has contracted out a third-party to maintain a good database system for the program. Specifically, the database has documented in detail every PV system that customers requested. Key data fields include 22 important dates during the PV installation process, customers’ zip code, city, utility and county information, and various characteristics of the PV system such as price, system size, incentive, PV module and installer. All information is publicly available, which to some extent fills in the information gap held by customers and fosters the market competition among PV installers. For customers to receive the incentive, their PV systems have to pass the inspection of the local government, and also to be interconnected to the grid. On the supply side, the CSI has also certified and created a list of PV installers that every customer can choose from.

Although the CSI has ended in 2014 due to fast PV cost reduction starting from 2009, its experience has been transferred to other areas in the United States and in Europe. It is highly possible that other similar new technologies and products (e.g. the electric car and the battery) can adopt the CSI policy design, too. In summary, a good and successful policy may need to be simply, clear, credible, foreseeable, flexible, end-able, and incentive-compatible. The PV subsidy policy in China still has a long way to go when compared to the CSI.

Mark Muro, senior fellow and policy director of the Metropolitan Policy Program, discusses a plan to address the economic boom-bust cycle in states that rely heavily on “fracking” and how this plan can spur innovation, inclusive economic development, and de-carbonization in the U.S.

“Inclusive economic development is critical; it’s about widening the circle of prosperity to more people. An inclusive economy is a highly innovative one … one that provides many opportunities for building skills, and it is a sustainable one,” Muro says. “Sustainability is about smoothing the boom and bust cycles that are disruptive to people, communities, and the state economy. But it is also about a clean economy.”
