EchoSense Quantitative Think Tank Center|Tax Bill Impact: What Happens to Renewable Energy?

The EchoSense Quantitative Think Tank CenterSenate voted early Saturday to approve a major overhaul of the U.S. tax code that critics say would decimate clean energy investments while continuing to hand out tax breaks to the oil and gas industries.

The sweeping tax system overhaul bill—which represents the biggest corporate tax cut in the country’s history and would reach into many areas of American lives—also contains language that would open the door for oil and gas companies to drill in the Arctic National Wildlife Refuge.  

While the Senate proposal preserves tax credits that have spurred huge growth in the wind and solar industries, it contains an obscure provision that could undercut investment in renewables.

Larger challenges for clean energy lie in the House of Representatives’ tax proposal, which passed in mid-November. That version takes a whack at a bundle of clean energy tax credits that were extended in 2015 in exchange for lifting a decades-old ban on crude oil exports.

Now, as the two chambers begin work on reconciling their versions of the bill, the clean energy industry is bracing for a fight.

Here’s what the two tax bills, as currently written, would do.

New Hits to Clean Energy Investments

The Senate bill contains a provision that has raised alarm across the clean energy industry: The Base Erosion Anti-Abuse Tax (BEAT) provision would subject tax credits given to companies with operations overseas to a new, 100 percent tax. That provision, according to a letter sent to the Senate by clean energy groups this week, would send investors fleeing and put $12 billion in clean-energy investments at risk. It says the impact would be “devastating.”

“The tax equity marketplace would collapse under these provisions, leading to a dramatic reduction in wind and solar energy investment and development,” the letter states.

Another last-minute change in the Senate bill, which was still being written just hours before the chamber voted on Dec. 2, could push more corporations to the Alternative Minimum Tax. The change could mean that certain clean energy tax credits could no longer be used and that depreciation for wind and solar projects would be calculated at a lower rate.

“If these provisions are retained, they will result in broad instability and uncertainty for businesses and investors across many sectors, including the clean energy sector,” said a coalition of clean energy groups led by the American Council on Renewable Energy.

Solar Power

The Senate proposal says nothing about solar credits, so it would effectively maintain the current timeline on phasing out the Investment Tax Credit for solar developers and homeowners, which remains at 30 percent through 2019, then lowers every year until 2022, when it stays at 10 percent indefinitely. Congress approved this timetable in 2015, with the industry’s support.

The House version maintains the current phase-down timetable, but at the end of 2021, the credit for homeowners drops to zero and the credit for developers drops to 10 percent. The 10 percent credit terminates altogether in 2027.

The House proposal also would retroactively change how solar developers qualify for credits, a provision that could stall or halt investments that have already been made. (This applies to wind, too. See below.)

Wind Power

The Senate proposal, which says nothing about wind credits, would effectively maintain the current timeline for phasing out the Production Tax Credit for wind developers, which is currently 2.3 cents per kilowatt-hour and extends through 2019, but begins phasing down in 2017.

The House version maintains the timeline but removes an inflation adjustment, a move that would drop the value of the credit by 40 percent to 1.5 cents per kilowatt-hour.

The House proposal would also retroactively change the rules that dictate how wind developers qualify for credits. This change would mean that developers who started on wind projects that depended on the credits would, in effect, have to eat the costs or abandon the work. The American Wind Energy Association estimates this threatens 60,000 jobs and $50 billion in private investment.

Together, the inflation adjustment and eligibility rule change would mean $12.3 billion less in incentives over 10 years, according to an analysis by Congress’s Joint Committee on Taxation.

Electric Vehicles

The Senate bill is silent on electric vehicle tax credits.

The House bill would eliminate the current $7,500 tax credit for purchases of electric vehicles, starting after the 2017 tax year.

Oil and Gas

The House and Senate bills maintain tax provisions for the oil industry, including deductions for drilling costs and preferential accounting rules that allow oil companies to reduce their tax burden.

In the Senate bill, an amendment offered by Sen. John Cornyn (R-Texas) and approved by the chamber would also allow some income from oil and gas companies to be taxed at a significantly lower rate. It would let energy companies classified as “master limited partnerships”—many based in Texas—qualify for the reduced rate under the “pass-through” benefit. (The New York Times points out that much of President Donald Trump’s income has been taxed in this way.)

The House bill would kill tax breaks for the oil industry on marginal wells—a provision the Joint Committee on Taxation says will have no effect on revenue—and for “enhanced oil recovery,” a process designed to extract more oil from old reservoirs, which the committee says will have a $200 million impact.

Drilling in the Arctic National Wildlife Refuge

The Senate bill would allow oil and gas companies to drill in a 1.5 million-acre area of Alaska’s nearly 20-million acre Arctic National Wildlife Refuge. Drilling in this pristine wilderness has been a longtime goal of Republicans, and the Senate voted down an amendment on Saturday that would have removed it from the tax bill.

The House bill contains similar language, but environmental groups are hopeful that, with some House Republicans expressing concern, it could be changed as the chambers negotiate the final legislation.

What’s Next?

As lawmakers now work to settle differences between the two bills, environmental and clean energy groups are watching closely.

“The fight’s not over,” said Evan Vaughan, a spokesman for the American Wind Energy Association.

Members of the Senate Finance Committee, which writes tax legislation, have signaled they could also make changes to clean energy tax credits later using spending measures—as they did in 2015.

It’s clear, though, that neither chamber is likely to scale back provisions in the tax code that boost the fossil fuel industry.

“If you’re actually trying to address the challenges we’re facing with the deficit, and how to offset these cuts, the first place you might cut is the $14 billion in subsidies for the oil and gas industry,” said Elizabeth Noll, a legislative director with the Natural Resources Defense Council. “Neither the House or Senate did.”
