The ITC Cliff: Will Solar Be Economically Viable Without the ITC?
The ITC Cliff: Will Solar Be Economically Viable Without the ITC?

The solar investment tax credit (ITC) is one of the most important federal policy mechanisms to support the deployment of solar energy in the U.S. The ITC continues to drive growth in the industry and thereby job creation across the country.

The residential and commercial solar ITC has helped annual solar installation grow by over 1,600 percent since the ITC was implemented in 2006, which represents a compound annual growth rate of 76 percent. According to the Solar Energy Industries Association (SEIA), solar installations increased 30 percent in 2014, thanks partly to cheaper photovoltaic panels. Solar proponents note that the solar industry employs more than twice as many U.S. workers as coal mining and has added jobs 20 times faster than the rest of the economy. Additionally, approximately 27 GW of solar energy were installed in the U.S. in 2015 with installations expected to reach nearly 100 GW by the end of 2020.

The 30 percent ITC is paying dividends for the U.S. Solar is growing faster than any other domestic energy source as prices continue to plummet, even beating out coal and cheap natural gas in some markets. The solar industry created one in 78 of our country’s new jobs last year while providing living-wage salaries for more than 200,000 Americans.

Moreover, the roughly 210,000 Americans currently employed in solar is expected to double to 420,000 in the same time period, all this while spurring roughly $140 billion in economic activity. The continued success of the ITC demonstrates that stable, long-term federal tax incentives can drive economic growth while reducing prices and creating jobs in one of the fastest-growing industries in the U.S.

Many supporters say the abrupt end date of the 30 percent credit represents a “cliff” for the industry. Without the current incentive, they argue, installation of solar-power systems will plummet, and thousands of jobs in the industry will be lost as a result. However, others argue that the “cliff” isn’t as steep as it appears, and that solar will continue to grow even without the 30 percent credit—albeit not as quickly as before.

Can the Solar Industry Survive without the Current Credit?

According to Energy Information Administration data in 2015 (when the ITC was scheduled to expire at the end of 2016), if the 30 percent credit was not extended, rooftop solar PV installations would plunge 94 percent in 2017 from a year earlier and utility-scale projects would decline 100 percent, with neither recovering anywhere close to today’s levels even a decade from now. Bloomberg predicted solar installations would drop by two-thirds in 2017, which the SEIA estimate would cost the U.S. 100,000 jobs.

The ITC provided certainty in the business model. The multiyear assurance provided by the eight-year (2008 thru 2016) 30 percent credit leveraged billions in new high-tech innovation and project development, lowered risks to allow startups to launch new products and services, and resulted in tens of millions of panels installed across the U.S.

According to the Natural Renewable Energy Laboratory (NREL), the elimination of the ITC would not impact the industry growth because financiers, not developers, grab about half of the tax credit. The credit has proved an essential financing mechanism to getting solar built, even though some projects rely on complex tax-equity structures to monetize the credit.

Optimists also speculate that it will get easier for people to finance solar systems themselves with loans if the credit goes away. The residential solar market is shifting to more self-financing, but rising prices in the absence of the credit could make solar uneconomical and scare off buyers. The lack of a credit will also make it harder for utility-scale projects, which account for most solar investment dollars, to compete for scarce capital and against more carbon-intensive generation alternatives.

Bloomberg estimates that the loss of the tax credit will cause solar capacity to only quadruple, instead of quintuple, by 2022, which is still a substantial increase. A Wall Street Journal analysis reinforces this assessment. In 22 states, at least 1 GW of solar (and often much more) could be installed at a comparable cost to retail electricity prices by 2017, tax credit not included.

So why are the grimmer predictions about the future of solar incorrect? For starters, the cliff that people talk about is smaller than it appears. Most folks with solar on their rooftops used a third-party lease or power-purchase contract. That third party took on much of the financial risk and the responsibility for redeeming the 30 percent tax credit. These financial middlemen have absorbed nearly half of the tax credit, and as a result, solar developers and customers have received an effective discount of 15 percent instead of 30 percent. So the current incentive isn’t as big as it looks, and the effect of losing the incentive won’t be as severe as many think.

What’s more, the change to the tax credit will open up new options for financing. Solar energy’s low risk and steady returns are attracting new investors whose profit expectations are much lower than many currently participating in solar financing. Additionally, solar securitizations are becoming more widely utilized, attracting new institutional investors.

If the change in the tax credit opens the door to more sizable, low-margin investors that offer a discounted cost of debt and equity for solar projects, the Wall Street Journal estimates that the net cost of solar would rise just 2.5 percent with the loss of the tax credit.

The change to the credit may also drive prospective solar clients, with decent credit, from leasing to lower-cost self-financing. With less paperwork to file, the relatively lower costs and higher returns of ownership become more evident.

A November 2014 pro forma analysis by NREL suggests that self-financing lowers the cost of solar by 23 percent for residential customers and 87 percent for commercial customers.

It’s easy to assume that losing the federal tax credit is nothing but a 30 percent cut in the growth potential for solar energy. But this ignores several countervailing forces, from the middlemen’s current cut to falling costs to the advent of low-cost financing. Even though coal and gas retain subsidies like heavily socialized pollution costs, solar doesn’t need the federal tax incentive to compete. Instead, the market provides several ways to glide over the solar tax cliff.

Comparison of Costs

A comparison of the cost per kWh for solar and existing electricity is as follows:

  1. Non-renewable retail residential electricity rates per kWh have increased about 4 percent on average (Nov 2005 thru Nov 2014), per year, over the last 10 years. According to the Energy Information Administration, residential electricity rates have increased nationally by around 30 percent in the last 10 years – from about 9¢ per kWh in 2005 to about 13¢/kWh in 2014.
  2. Natural gas prices are expected to increase, as a result of higher anticipated infrastructure costs.
  3. Coal-fired electricity will continue to rise.
  4. Solar rates per kWh have decreased from approximately $.071 in 2009, to $.050 in 2015.

The cost of renewable energy is decreasing, while the cost of traditional non-renewable energy sources is increasing. However, the existing electrical grid is designed for continuous energy flow and is not designed to “store” any excess electricity. If a new grid was to be built today, it would bear little resemblance to the existing system. The U.S. electrical grid is wearing out. Depreciation expense exceeds new investment.

Costs of generation, both fixed and variable are rising. Costs of transmission and distribution are rising. The costs of doing business are rising. On the other hand, utility revenues from energy sales are declining as a result of conservation, energy efficiency, distributed generation and competition. Utilities generally collect a majority of their revenue through charges for energy usage, a variable quantity, yet the majority of their costs are due to capacity, a fixed quantity that doesn’t diminish with diminished energy consumption. Traditional approaches to rate design are no longer sufficient. Simply raising rates to overcome declining revenues only increases the incentive for customers and competitors to further displace purchases from their utility.

According to Philip Moeller, a member of the Federal Energy Regulatory Commission, “We are now in an era of rising electricity prices,” the steady reduction in generating capacity across the nation means that prices are headed up. “If you take enough supply out of the system, the price is going to increase,” Moeller said.

In fact, the price of electricity has already been rising over the last decade, jumping by double digits in many states, even after accounting for inflation. In California, residential electricity prices shot up 30 percent between 2006 and 2012, adjusted for inflation, according to Energy Department figures. Experts in the state’s energy markets project the price could jump an additional 47 percent over the next 15 years.

New investment has diminished:

  1. Growth in consumption has slowed since 1973
  2. Environmental and other concerns restrict construction of new facilities
  3. Utility companies now incur significant risk of not recovering all their costs much less a reasonable return on investment.

Other Factors to Consider

A key development and new concept is the “grid edge.” As further discussed herein, the most important and impactful developments in the electric utility industry in the foreseeable future will be at the distribution edges of the grid, many if not most on the customers’ sides of the meter. This means tremendous challenges for electric distribution utilities, but at the same time fantastic opportunities to bring a new and better world to their consumers and communities.

The key to the success in renewable energy sources is the development of a new grid system, which provided the following:

  1. Distributed generation and storage
  2. Two-way power flow
  3. Microgrids

The problems confronting the electricity system are the result of a wide range of forces: new federal regulations on toxic emissions, rules on greenhouse gases, state mandates for renewable power, technical problems at nuclear power plants and unpredictable price trends for natural gas. Even cheap hydro power is declining in some areas, particularly California, owing to the long-lasting drought.

New emissions rules on mercury, acid gases and other toxics by the Environmental Protection Agency are expected to result in significant losses of the nation’s coal-generated power, historically the largest and cheapest source of electricity. Already, two dozen coal generating units across the country are scheduled for decommissioning. When the regulations go into effect next year, 60 GW of capacity — equivalent to the output of 60 nuclear reactors — will be taken out of the system, according to Energy Department estimates.

Moeller warns that these rapid changes are eroding the system’s ability to handle unexpected upsets, such as the polar vortex, and could result in brownouts or even blackouts in some regions as early as next year. He doesn’t argue against the changes, but believes they are being phased in too quickly.

The federal government appears to have underestimated the impact as well. An Environmental Protection Agency analysis in 2011 had asserted that new regulations would cause few coal plant retirements. The forecast on coal plants turned out wrong almost immediately, as utilities decided it wasn’t economical to upgrade their plants and scheduled them for decommissioning.

The lost coal-generating capacity is being replaced largely with cleaner natural gas, but the result is that electricity prices are linked to a fuel that has been far more volatile in price than coal. The price of natural gas now stands at about $4.50 per million BTUs, more expensive than coal. Plans to export massive amounts of liquefied natural gas, the rapid construction of gas-fired power plants and the growing trend to convert the U.S. heavy truck fleet to natural gas could exert even more upward pressure on prices. Malcolm Johnson, a former Shell Oil gas executive who now teaches the Oxford Princeton Program, a private energy training company, said prices could move toward European price levels of $10.

The loss of coal is being exacerbated by problems at the nation’s nuclear plants. Five reactors have been taken out of operation in the last few years, mainly due to technical problems. Additional shutdowns are under consideration.

At the same time, 30 states have mandates for renewable energy that will require the use of more expensive wind and solar energy. Since those sources depend on the weather, they require backup generation — a hidden factor that can add significantly to the overall cost to consumers.

Nowhere are the forces more in play than in California, which has the nation’s most aggressive mandate for renewable power. Major utilities must obtain 33 percent of their power from renewable sources by 2020, not counting low-cost hydropower from giant dams in the Sierra Nevada mountains.

In some cases, the renewable power costs as much as twice the price of electricity from new gas-fired power plants. Newer facilities are more competitive and improved technology should hold down future electricity prices, said former FERC Chairman Jon Wellinghoff, now a San Francisco attorney.

But San Francisco-based consultancy Energy + Environmental Economics has projected that the cost of California’s electricity is likely to increase 47 percent over the next 16 years, adjusted for inflation, in part because of the renewable power mandate and heavy investments in transmission lines.

The mandate is just one market force. California has all but phased out coal-generated electricity. The state lost the output of San Onofre’s two nuclear reactors and is facing the shutdown of 19 gas-fired power plants along the coast because of new state-imposed ocean water rules by 2020.

“Our rates are increasing because of all of these changes that are occurring and will continue to occur as far out as we can see,” said Phil Leiber, chief financial officer of the Los Angeles Department of Water and Power. “Renewable power has merit, but unfortunately it is more costly and is one of the drivers of our rates.”

“While renewables are coming down in cost, they are still more expensive,” said Russell Garwacki, manager of pricing design and research at Southern California Edison. The company is imposing a 10 percent price hike this year to catch up with increased costs in the past.

Officials at the California Public Utilities Commission (CPUC), responsible for setting utility rates, dispute predictions of large-scale electricity price hikes in the near future. Edward Randolph, head of the CPUC’s energy division, said price increases were not likely to exceed the rate of inflation, though the commission has refused to spell out the data on which it bases its projections. In any case, while California already has some of the highest hourly rates for electricity in the nation, the average consumer in the state pays bills that are below the national average because overall electricity use is so low.

The push to wean California off fossil fuels for electricity could cause a consumer backlash as the price for doing so becomes increasingly apparent, warns Alex Leupp, an executive with the Northern California Power Agency, a nonprofit that generates low-cost power for 15 agencies across the state. The nonprofit was formed decades ago during a rebellion against the CPUC and the high prices that resulted from its regulations. “If power gets too expensive, there will be a revolt,” Leupp said. “If the state pushes too fast on renewables before the technology is viable, it could set back the environmental goals we all believe in at the end of the day.”
