Diplomacy and International Institutions
The International Energy Agency’s Hybrid Model
This guest post is co-authored by Stewart Patrick, senior fellow and director of the International Institutions and Global Governance program at the Council on Foreign Relations, and Naomi Egel, former research associate at the Council on Foreign Relations and doctoral student at Cornell University.  International institutions created in the twentieth century face the daunting challenge of remaining relevant as the geopolitical landscape shifts. This reality is abundantly clear in the energy field, as the International Energy Agency (IEA)—formed by Western countries in response to OPEC’s 1973 oil embargo—finds its membership less and less representative of global energy consumption. In a recent Foreign Affairs article, we argue that the IEA’s outreach to nonmember states, especially rising powers—while stopping short of offering membership—is a wise approach that could pay economic, environmental, and geopolitical dividends for the United States and other IEA members. To join the IEA, countries must hold and maintain emergency oil stockpiles equivalent to 90 days of net imports. Even more demanding, they must also be members of the OECD—meeting all the hoops and hurdles that status requires. Recognizing the growing importance of countries outside its ranks, the IEA has developed multiple programs to strengthen partnerships between the agency and nonmembers. These range from limited technology sharing arrangements to the deepest level of partnership—known as association agreements. These agreements allow select nonmembers—at present China, Indonesia, and Thailand—to participate in many IEA meetings and secure the agency’s technical assistance in improving their own energy security. While these agreements fall well short of full membership (and emerging powers are not exactly banging on the IEA’s door to be admitted as full members), they represent the best way forward for global energy governance. As we describe in the article, these partnership arrangements bring current IEA members tangible economic, ecological, and geopolitical benefits: On the economic front, by improving the accuracy and sharing of data on national energy production and consumption and by promoting the gradual creation of fuel stockpiles upon which countries can draw in the event of unexpected supply interruptions, the IEA’s closer association with rising powers should work to make the world less vulnerable to supply and price shocks. Similarly, the IEA’s outreach efforts reinforces the agency’s efforts to combat global warming and its role as a hub for promoting clean energy technologies, including in some of the world’s major greenhouse gas emitters. Drawing on its analytical strengths, the IEA should provide technical assistance and training to help emerging economies measure progress toward their emissions reductions targets. It should also promote research and development for clean energy, especially through its energy technology initiatives, which involve both member and nonmember countries, as well as the private sector. Finally, as we note: The association agreements could even pay geopolitical dividends by helping embed rising powers within the liberal order’s existing institutions. That is especially important with respect to China, as the drama over the establishment of the Asia Infrastructure and Investment Bank demonstrated. Indeed, when Beijing assumed the chair of the G-20 in December 2015, senior U.S. officials expressed anxiety to one of us that it might exploit the opportunity to create an alternative Asia-centered, multilateral energy organization—perhaps even launching it at this September’s G-20 summit in Hangzhou. China’s association agreement makes this scenario less likely, and it will help acclimatize Chinese officials to greater transparency and information-sharing in the energy sector. Still, it is not a given that the IEA will reap the potential benefits of these outreach agreements, which are a significant departure from the agency’s traditional priorities. At the end of the day, the IEA remains a membership organization, and the scope and depth of its outreach agenda will reflect the preferences of its own members rather than its secretariat. The agency is making a laudable effort to adapt to a changing energy landscape and increase its relevance to emerging powers, without sacrificing its status as the world’s premier source of authoritative data and analysis on energy matters. But the success of these experiments will depend on whether its members provide the agency with the budget and personnel it requires to fulfill a more ambitious agenda. And it will require discipline on the part of the IEA itself in setting priorities and defining goals, so that it avoids accusations of mission creep. . Expanding training programs and new technology initiatives should not diminish the agency’s focus on producing authoritative data and analysis. The IEA’s embrace of nonmember countries provides a fascinating case study of what is a recurrent challenge in contemporary global governance: Namely, how can international institutions adapt their membership to a changing international order while still preserving their core competencies and the goals of their members? Still, as we conclude: The IEA’s experiments with partnerships with nonmembers and its emphasis on flexibility are a valuable primer for international institutions seeking to remain relevant. The agency’s approach will help member states—including the United States—promote the rules and norms underpinning the organizations they established and bring rising powers into the fold.

Time to Repeal U.S. Oil and Gas Tax Breaks
This post is co-authored by Sagatom Saha, research associate for energy and foreign policy at the Council on Foreign Relations. Read "The Impact of Removing Tax Preferences for U.S. Oil and Gas Production," a Discussion Paper from CFR’s Program on Energy Security and Climate Change in the Center for Geoeconomic Studies. Last week, CFR published a paper weighing in on the decades-long debate over tax preferences for U.S. oil and gas production (the first tax preference is actually over a century old, and tax reform has been a contentious fixture in Congressional budget battles since the 1970s). Advocates for reform argue the preferences hinder climate goals and waste $4 billion a year. Defenders of the tax preferences argue that repealing them would decimate domestic oil and gas production, jeopardizing U.S. energy security, jobs, and the economy. To assess these dueling arguments, Gilbert Metcalf, professor of economics at Tufts University, quantifies the effects of removing the three major tax preferences for U.S. oil and gas production (expensing of intangible drilling costs, percentage depletion, and the domestic manufacturing tax deduction). He finds that: Domestic oil drilling activity could decline by roughly 9 percent, and domestic gas drilling activity could decline by roughly 11 percent, depending on natural gas prices. These declines in drilling would in turn lead to a long-run decline in domestic oil and gas production. As a result, the global price of oil could rise by 1 percent by 2030 and domestic production could drop 5 percent; global consumption could fall by less than 1 percent. Domestic natural gas prices, meanwhile, could rise between 7 and 10 percent, and both domestic production and consumption of natural gas could fall between 3 and 4 percent. This might mean an increase of two pennies per gallon of gasoline at the pump and seven dollars per month for an average household’s electricity bill—small effects compared to recent variations in prices. To date, no study that was transparent about its methodology had rigorously assessed how oil and gas firms might respond to tax reform. In particular, some previous studies had oversimplified the problem, assuming that the $4 billion in lost annual government revenue equaled the value of the preferences to firms. But since tax preferences increase firms’ immediate cash availability, they are even more valuable to the firms. On top of this, previous studies failed to hone in on marginal effects—that is, how the presence or absence of tax breaks affect which projects firms will consider profitable enough to drill. Recognizing that this paper improves upon past studies, The New York Times’ Eduardo Porter writes: Mr. Metcalf’s analysis is the most sophisticated yet on the impact of government supports, worth roughly $4 billion a year. Extrapolating from the observed reaction of energy companies to fluctuations in the price of oil and gas, he models how a loss of subsidies might curtail drilling and thus affect production, prices and consumer demand. After quantifying the minimal effects tax reform would have on oil and gas prices, production, and consumption, Metcalf concludes that its direct effects on U.S. energy security, greenhouse gas emissions, and economic health are also limited. But eliminating subsidies to fossil fuel producers can strengthen U.S. credibility and leverage in international climate diplomacy. In 2009, the G20 countries made a historic agreement to phase out fossil fuel subsidies. Yet the 2016 G20 energy ministerial recently concluded with a disappointing announcement that made no mention of a concrete timescale for achieving this goal. U.S. fossil fuel subsidy reform could help break the logjam. For example, the United States and China will each publish peer reviews of the other’s fossil fuel subsidies at the G20 general meeting in September, and U.S. action to repeal its own subsidies may spur China to make similar efforts. It would also strengthen U.S. leadership to call on other developed and developing countries to remove both producer and consumer fossil fuel subsidies that drive up emissions around the world.

What Will It Take to Turn Natural Gas Around in India?
This guest post is co-authored by Sarang Shidore, a visiting scholar at the LBJ School at the University of Texas at Austin, and Joshua Busby, associate professor of public affairs at the Robert S. Strauss Center for International Security and Law at the LBJ School at UT Austin. India is among the fastest-growing large energy consumers in the world. According to the IEA, India’s share of primary energy demand accounted for about 5.7% of the global total in 2013, and with its energy demand set to increase by 30%, India’s share of the global total could be nearly 7% by 2020.  Reining in greenhouse gas emissions from its fast-growing economy will be crucial to combat global climate change. Though it has laid out an ambitious roadmap to scale up renewable energy over the next decade, the bulk of Indian electricity generation is still expected to come from burning coal, and oil is widely expected to remain the dominant source of transportation fuels for the foreseeable future. Natural gas penetration in India, however, is extremely low compared to that in many major economies (see figure), with the exception of China. This is concerning, since natural gas could bring substantial benefits to India and the world. Compared with burning coal or oil, burning natural gas releases significantly lower greenhouse gas emissions per unit of energy (provided that methane leakage from natural gas production and delivery is limited). Natural gas power plants also produce lower levels of pollutants harmful to human health, compared with coal-fired power plants—this is particularly important given India’s high urban air pollution levels. And natural gas could be a bridge fuel in the transition to renewable energy because natural gas power plants can provide flexible, or peaking, power that makes it easier to integrate unpredictable wind and solar energy into the power grid. Indeed, in the United States a major revolution in producing low-cost shale gas has contributed to an electricity transition away from coal and toward renewable energy. So it is important to understand the barriers for natural gas adoption in India and examine public policy options to reduce them. Natural Gas consumption in India compared with that in other major economies (Compiled by authors with data from EIA, 2012). What’s Holding Natural Gas Back? Increasing the production and consumption of natural gas has faced a number of barriers in the Indian market. Most evidently, India’s conventional gas reserves are estimated to be relatively modest at about 1.4 trillion cubic meters, only 0.7% of the global total. Moreover, exploration and exploitation activities have been sub-optimal at best, and producers have considered deep water reserves economically unviable until recently. Low production is largely due to Indian government regulations that limit the gas price that domestic producers can charge in the domestic market. Some analysts have argued forcefully for a higher domestic gas price to incentivize production and attract greater private investment in the upstream gas market.  In addition to India’s limited conventional reserves, some unconventional gas reserves exist in the form of shale gas and coal-bed methane. Multiple barriers, such as water and land availability, have impeded shale gas production, though there is good potential for exploiting coal-bed methane. Compounding the lack of domestic reserves, international pipelines have stalled. Projects such as the Iran-Pakistan-India, Myanmar-Bangladesh-India, Oman-India, and Bangladesh-India have stalled for a number of reasons related to cost, technology, and international and domestic politics. Prospects for the only viable pipeline currently on the drawing board, the Turkmenistan-Afghanistan-Pakistan-India (TAPI) pipeline, remain uncertain due to the deteriorating security situation in Afghanistan. In general, it is unlikely that international pipelines can deliver substantial gas supplies to India, at least over the next 10–15 years. Liquefied Natural Gas (LNG), which can be shipped around the world, is another major route for expanding gas supplies. LNG provides flexibility and shorter time horizons in contracting with active markets in both long-term and spot, or immediate, trading. However, high prices have traditionally made LNG unattractive for India. Historically, Asian countries have had difficulty procuring affordable LNG because of the so-called “Asian premium” in landed gas prices. Typical LNG prices were in the neighborhood of $16 per MMBtu [million British thermal units, a unit of energy] until recently. This was a cost far too high for the Indian electricity and other demand markets to bear—for example, gas-powered generation is competitive with generation from imported coal only at a gas price somewhere below $5 per MMBtu. India also suffers from a deficiency of infrastructure for domestic deployment of natural gas. India has delayed constructing LNG infrastructure to receive supplies from abroad, and new builds are ongoing. Though key regasification facilities (that convert LNG to pipeline gas) at the ports of Dahej, Hazira, Dabhol, and Kochi are operational, they can handle only  about 20 mmtpa (million metric tonnes)/year at the moment, which represents about 30% of current gas consumption. Given that domestic production increases will fall well short of demand even under optimistic scenarios, a major expansion of gas consumption will require a major expansion of LNG import capacity. India has ambitious expansion plans to raise its import capacity to 47.5 mmtpa/year by 2022, which will represent about 45% of IEA’s projected gas consumption for India in that year. However, substantial delays in large infrastructure projects are the norm in India. Moreover, once LNG is received in Indian ports, it still needs to be transported to major demand centers that can be far away. In general, gas transport is more challenging than oil transport, and pipelines are the best solution for moving large quantities of gas across country as large as India. Southern and eastern India are poorly served by pipelines. Critical projects such as the Kochi-Mangalore-Bangalore pipeline have been delayed owing to land acquisition issues. And infrastructure (e.g. filling stations) for Compressed Natural Gas (CNG) for transportation and city gas for domestic use is limited and could be expanded to many more Indian cities. Market Shifts Are Improving India’s Gas Prospects Low prices are making gas more attractive. A major development in gas markets in Asia has been the recent crash in LNG prices, which are now trading in the neighborhood of $5/MMBtu. It is undoubtedly risky to plan long-term energy transition strategies based on short-term market vagaries. However, there is good reason to believe that low LNG prices in Asia will persist, given new sources of gas supply. The United States recently began shipping LNG to India, and Australian gas will be delivered beginning late 2016. If the US-Iran nuclear deal continues to facilitate Iran’s entry into global markets, then Iran’s LNG supplies, expected on the global market post-2020, would further increase global supply. And East Africa is an additional major future source for LNG on the horizon. Furthermore, structural factors are putting downward pressure on prices. Two major developments in LNG markets are now well underway that could reduce LNG prices moving forward. One is the steady decline of traditional LNG contracts that index natural gas pricing to oil prices, which could erode the “Asian Premium." The other is a simultaneous dynamic of slowing demand growth in key countries like Japan and South Korea and accelerating supply from new sources such as the US and Australia. Both factors are exerting downward pressure on medium-term LNG prices which could persist for the longer term, shifting deals toward shorter-term, more flexible transactions. India has been quick to react to these changes, having renegotiated an earlier deal with Qatar to bring its contracted price from $12-13 per MMBtu to $6-7 per MMBtu—a reduction of about half. The Modi government is in talks to import LNG from the Chevron-led Gorgon project in Australia. India is also in preliminary talks with other Asian countries to create a buyers’ alliance that can jointly negotiate an extended regime of lower prices with key suppliers. India has also achieved some domestic pricing reform. As of 2016, India now incentivizes production from deepwater wells at a higher price than before of $6.61 per MMBtu. This has helped close the gap between regulations and the position of Indian producers such as Reliance, which recently withdrew a key arbitration proceeding against the Indian government on stalled production at a major gas field. Finally, given citizens’ increasing anger over worsening air quality in New Delhi and elsewhere, recent court rulings in India have banned diesel vehicles in a few cities, providing new market opportunities for CNG use in the transportation sector. Regulatory Reform can HELP Gas Turn Around The government’s recent Hydrocarbon Exploration Licensing Policy (HELP) attempts to reform the previously unwieldy system by streamlining license procedures, allowing developers to define acreage of exploration fields, moving from a profit-sharing to a revenue-sharing model, and allowing “pricing freedom” to new gas finds subject to a cap determined by a complex formula. This cap turns out to be quite low in an era of low fossil fuel prices. However, more regulatory reforms are needed to incentivize domestic production. Most analysts have argued for greater pricing freedom, in the range of $6-$14 per MMBtu, depending on the type of gas field in question. However, it is also clear that gas at these prices cannot compete with coal for electricity generation. They will also greatly increase fertilizer subsidies. There are major political barriers to reducing or eliminating the fertilizer subsidy regime, which directly benefits farmers, who compose more than half of India’s voters. Thus, India has three policy choices. The first is to prioritize domestic production through an across-the-board pricing reform, reflecting domestic market dynamics. This has the advantage of increasing energy independence and building in greater price predictability. However, this option will substantially increase the fertilizer subsidy burden, though higher government royalties that would accrue in a higher price regime could offset some of this increase. Barring politically difficult power tariff increases, this also means compromising gas-fired grid-based electricity expansion, which in turn would have a negative effect on renewables growth. A second choice has emerged in the wake of the recent dramatic drop in LNG prices in Asia. India could bet on a sustained low price LNG environment and focus almost entirely on increasing gas imports to meet future demand rise. This option requires more aggressive gas port and pipeline infrastructure goals and their on-time completion and energizing pipeline projects such as TAPI. It however carries the risk that Asian gas prices could sharply increase at some point in the future due to geopolitical or other factors endangering Indian energy security. The third option, and the one we recommend, is to seek the middle ground—undertake selective but deeper pricing reform, perhaps for the more challenging ultra-deepwater fields and coal-bed methane, but also pull out all stops to ensure that ambitious LNG and pipeline infrastructure plans meet stated deadlines to enable accelerated imports. Existing subsidy regimes would largely remain intact, but deregulated markets in piped gas, CNG, captive power plants, and industrial sectors could absorb much of the price increase, especially if the state acts to facilitate large demand volumes for gas in the domestic and transport sectors. This will require a major build-out of gas infrastructure (such as pipelines to homes and CNG filling stations) to generate the requisite demand at these prices. It will also require strong domestic regulations to limit methane leaks from production and transport sites, lest the climate benefits of methane over coal disappear. Additionally, the government should consider including the steel sector within the “Tier 1” list of sectors to which domestic gas is released first. Steel manufacturing is a major source of India’s carbon emissions, and there are substantial climate and air quality benefits in encouraging it to use natural gas rather than coal. Additional Policies and International Coordination Are Also Important The diesel vehicle ban promulgated by the National Green Tribunal, India’s top environmental court, must be supported strongly. Not only should the government abandon its current opposition to extending the ban to other cities, but it should also proactively support its extension. This will not only have major air quality benefits, but will also enable demand for natural gas in the transportation sector to take off, a critical condition for the regulatory reforms listed above to become viable. The buyers’ alliance initiative from the Modi government is an excellent idea. Major consumers such as South Korea, Japan, Thailand, and even China could be included in these discussions. If Asian LNG prices converge strongly with landed prices in Europe, there is also the future possibility of including EU states in this conversation. The United States can significantly promote greater adoption of natural gas in India. It can participate in  plurilateral talks on coordination of gas buyers and continue to publicly disseminate information on air quality as a public health issue. The US can also leverage some of its recent experience on quantifying and regulating methane leakage to help India establish an effective policy framework. And quiet U.S. diplomacy can pay off when pursued appropriately, exemplified by India’s shift in stance on bringing HFCs [hydrofluorocarbons, potent greenhouse gases] under the Montreal framework. Though enhancing India’s consumption of natural gas will inevitably mean greater imports, compared with domestically abundant coal, there are enormous benefits from increasing adoption of natural gas that can aid India’s development and public health as well as global efforts to combat climate change. Some might question whether expensive investments in natural gas will come at the expense of a renewable energy revolution. In fact, the reality is quite the opposite—barring a low-cost, grid-scale storage technology breakthrough, a major revolution in wind and solar energy cannot be achieved without adequate flexible power sources to meet peak load power demand. Natural gas and hydropower provide by far the best source of peaking power. With major constraints to hydropower’s expansion in India, gas-fired plants are essential to India’s achievement of the ambitious renewables targets it committed to in the Paris climate agreement last year.

    Why the Silicon Valley Model Failed Cleantech
    It’s no secret that venture capital (VC) has fled from the clean energy technology (cleantech) sector, and as a result, new cleantech company formation has slowed. But why did this happen, and is there a future for cleantech? To answer these questions, today I’m excited to release an MIT Energy Initiative (MITEI) paper entitled, "Venture Capital and Cleantech: The Wrong Model for Energy Innovation,” with my colleagues Ben Gaddy at the Clean Energy Trust and Frank O’Sullivan at MITEI. In this morning’s Financial Times, Ben and I summarize our findings: We compared the performance of every medical technology, software technology, and cleantech company that received its first round of VC funding between 2006 and 2011. We found that betting on cleantech start-ups just does did not make sense for VCs, because the sector could not deliver the outsized returns found in other sectors. In particular, companies developing new solar panels, batteries, biofuels, other new energy materials and manufacturing processes collectively destroyed over 80 per cent of the initial capital investment by VCs. Many required large amounts of funding to build factories and their technologies took longer than five years to develop. The few that succeeded still did not deliver enough capital return for VCs to justify staying in the sector. A Losing Combination: High Risk and Low Returns Below, Figure 2 from our MITEI paper breaks down the underperformance of the cleantech sector: Interestingly, the way we classify Nest Labs—which sells sleek thermostats that intelligently regulate indoor temperature to reduce power bills—heavily influences the results. If we count Nest as a software company, which is reasonable, overall cleantech sector performance plunges. This suggests heterogeneous company performance within the cleantech sector. Indeed, when we broke down cleantech into five subsectors, we found that clean software companies were profitable investments, whereas materials and hardware companies performed the worst (Figure 3). Wanted: Corporate Partners It makes sense that cleantech companies scaling up new materials or hardware might underperform software companies that required less up-front capital from investors and paid VCs back handsomely after only a few years. But some other factor is needed to explain why cleantech underperformed the biomedical sector, which can also be capital-intensive and has successfully scaled up lab bench innovations. That factor is corporate support. Figure 4 from our paper demonstrates that biomedical start-ups were twice as likely to be acquired than cleantech start-ups, offering VCs lucrative returns on their investments. In contrast to biomedical corporations willing to strategically invest in innovative start-ups, energy companies—whether electric utilities or oil and gas firms—rarely invest in start-ups or even in-house research and development. Just this weekend, I was reminded of the importance of corporate partnership when I sat down with a cleantech entrepreneur who isn’t following the Silicon Valley model. Bill Brown, CEO of NET Power, is commercializing an innovative power plant that runs on natural gas but produces pipeline-ready carbon dioxide for enhanced oil recovery, other industrial uses, or sequestration rather than spewing carbon emissions into the air. (Dave Roberts at Vox has an excellent write-up on the details). Brown is well on his way to building a 50 MW demonstration project in Texas thanks to support from corporate investors and partners. Exelon (a utility) and CB&I (an engineering firm) have made equity investments of $150 million, and Toshiba (a conglomerate with experience building turbines) has developed a special combustor and turbine in exchange for an exclusivity license with NET Power. Brown told me that working with corporate partners has brought engineering expertise, substantial capital, and the confidence to put steel in the ground. Beyond Venture Capital We close our paper by noting: One lesson that entrepreneurs may take away from this story is that cleantech companies need to adapt to fit the constraints of VCs. Perhaps any cleantech company ought to be a software company in disguise, and new materials and processes are hopeless money losers. That lesson is wrong and could be a disastrous impediment to the development of much-needed clean technologies to upend the world’s energy systems—a transformation that software alone cannot accomplish. The correct lesson is that cleantech clearly does not fit the risk, return, or time profiles of traditional venture capital investors. And as a result, the sector requires a more diverse set of actors and innovation models. Those new actors include Bill Gates’ Breakthrough Energy Coalition, which has pledged to provide billions of dollars in “patient capital” that could transcend the capital and time constraints of VC investors. Institutional investors and corporations will also be crucial to supporting the cleantech sector. To entice these new private actors, public policymakers must de-risk their investments, and we outline a suite of initiatives to do so. Indeed, we conclude, “the rise and fall of hundreds of start-ups might have an upside if a new generation of public and private support avoids the missteps of the cleantech VC boom and bust.” Read our MIT Energy Initiative working paper here, and our Opinion piece in the July 26, 2016 edition of the Financial Times here.

    Securitization: The Next Big Thing in Solar Energy Financing
    This post was co-written by Sagatom Saha, research associate for energy and foreign policy at the Council on Foreign Relations. Recent headlines from the solar energy industry have been bleak. SunEdison—a solar developer which just a year ago aspired to join the ranks of multinational oil companies as an energy “supermajor”—declared bankruptcy in April, after wiping out $9 billion in market value. And the share prices of Yieldcos, the financial vehicles which promised to tap vast capital markets to finance renewable energy projects, have plummeted as well. Last year, I wrote that Yieldcos’ aggressive growth targets and financial model made them vulnerable to the vicious downward spiral that has played out. But as the focus of the industry moves beyond Yieldcos, another example of financial engineering could take center stage. Solar securitization, which dices, bundles, and sells loans for distributed solar projects to deep-pocketed investors, follows a tried-and-true model used to finance everything from cars to home mortgages. In a new MIT Energy Initiative Working Paper, Frank O’Sullivan and Charlie Warren assess the emerging class of residential solar asset-backed securities (ABS). They conclude that this approach has the potential to bring substantial low-cost capital to fuel residential solar adoption, but the model will need to evolve to surmount existing barriers. In particular, securitization could take off if smaller companies get involved and better data emerges to de-risk solar investments. Familiar But Exotic Securitization is probably most well-known for causing a massive recession in 2008, when the subprime mortgage bubble burst and investors realized that securitizing bad loans did not magically extinguish risk. Fortunately, solar securitization so far looks much safer, since the underlying loans are to consumers with much higher credit scores. Although securitization has been around since the 1970s, solar securitization is relatively new—solar companies have only performed seven rounds of securitization, and the first one was in 2013. Still, all of these rounds look very similar to securitizations for other asset classes, like auto, home, or student loans, the authors explain: The solar ABS transactions to date adhere to the general framework of most securitizations, with some important exceptions. Solar ABS use a standard legal structure—the special purpose entity—to combine thousands of rooftop solar systems generating monthly cash flows. Importantly, the special purpose entity is a limited liability company, which is designed to mitigate bankruptcy risk between the solar provider (the originator) and the issuer of the solar ABS. The special purpose entity then issues new debt securities based on the cash flows from the solar leases/PPAs or loan payments. Fixed income investors buy the solar ABS and receive the interest payments. The big payoff from securitization is access to low-cost capital from deep-pocketed institutional investors. In theory, this would allow solar companies to accelerate the pace of solar installations and increase the size of the U.S. residential solar market. The results from the seven securitizations to date are promising—investors have agreed to purchase securities at reasonably low yields of ~4–6 percent (see table below, copied from the MIT paper). Solar ABS Transactions, 2013-2016   Still, the authors note, there are a couple twists: While solar securitization shares many similarities with other ABS, the structures have two specific nuances. First, tax equity investors are crucial because solar providers need to monetize the ITC. However, tax equity’s role in, and capital structure position among other investors, becomes more complicated during solar securitizations. Whereas tax equity investors are usually the senior claimants on the cash flows from the projects, securitization involves another class of investor seeking equally predictable returns: fixed income. Another feature of solar securitizations is their liquidity, or lack thereof. There is little trading of existing solar ABS, indicating a “buy and hold” strategy from institutional investors. The exact number of existing solar ABS investors is not public, but the available data point to relatively small numbers. For instance, Sunrun’s only securitization involved 19 investors according to company presentations. Solar ABS are, after all, esoteric and relatively small, with no issuances above $202 million to date. Asset-Backed Insecurities? Those quirks of solar ABS hint at the barriers that this emerging asset class will have to overcome to fuel rapid growth in residential solar. The authors of the MIT paper cite four in particular: Not enough companies may offer securitizations. To date, only two companies (Solarcity and Sunrun) have performed securitizations. These companies have the scale and diversity of projects to do so on their own, because securitization needs to be done in large chunks to attract institutional investors who avoid small transactions. Public policies could change. The economics of residential solar depend heavily on the method by which solar is compensated by a utility. In many states, solar benefits from “net metering,” which allows a consumer to sell excess solar power back to the grid at the retail rate. Some states—notably Nevada—have started to roll back net metering, raising the specter of reforms elsewhere (Nevada’s February 2016 decision helps explain why the yield on Solarcity’s ABS jumped nearly two percentage points between August 2015 and March 2016). On top of the state policy uncertainty, federal policy could change as well, especially if the IRS makes it more difficult for tax equity investors to invest alongside ABS debt investors. Interest rates could rise. Low yields for solar ABS depend on low underlying interest rates. But if the Federal Reserve continues to tighten rates in coming years, solar companies could see the cost of capital that they can raise through securitization increase. Moreover, worsening market conditions can increase yields on corporate bonds that also could increase solar ABS yields. Solar could become very cheap. This hardly sounds like a risk, but it is in fact an important differentiating risk from other ABS classes. If solar power continues to fall in cost, solar installations might have low “salvage” value in the case of a consumer loan default. From Esoteric to Mainstream Many of those barriers are out of the industry’s control. But the MIT report’s authors suggest one way for the industry to accelerate securitization, especially because ABS currently account for a tiny fraction of the overall U.S. residential solar market: One such option would be to combine transactions from multiple solar providers into a single structure, commonly known as “pooling.” Pooling securitizations across solar providers offers two opportunities in theory. First, smaller and medium-sized developers account for approximately 40 to 50 percent of the existing residential market by installed capacity. There are cash-producing, long-term contracted, and credit-worthy assets already deployed across the United States. Solving the supply problem on solar ABS could be accomplished not only through more securitizations from existing players, but also by expanding the range of originators. Second, other players in the solar ABS market would benefit from its expansion, including banks and rating agencies conducting additional transactions and applying best practices to date. If incentives are well aligned, expanding solar ABS to a new installer base could also have the added effect of increasing solar deployments writ large. In addition, the industry can improve the availability of data to reduce the risk perceived by investors. I spoke with representatives from kWh Analytics, a company that has built a database of 70,000 operating solar projects around the United States. They stressed that databases—for example of consumer credit—have de-risked other asset classes, and the same now needs to happen for solar. If solar companies can back up their projections of solar installation performance with hard data, investors may purchase solar ABS on more favorable terms (e.g., at a higher advance rate, which is the ratio of the debt raised to the underlying collateral. The 75 percent solar ABS advance rate is well below the 92 percent advance rate for autos and 99 percent advance rate for mortgages). And in the process, solar ABS might go from esoteric to mainstream.   Read the full MIT report here.
