The recent passage of H.R.1, the Tax Reform Bill (Bill), had several important provisions that will change the economics of corporate renewable energy projects. In this blog, we’ll focus on how the Bill will affect new, corporate-owned, solar PV installations. While there are a few provisions—such as BEAT, NOL, AMT, Interest Expense, and Partnerships—that will selectively affect some companies, our focus will be on those provisions that are likely to impact the broadest cross-section of companies currently considering installing and owning on-site solar PV. We’ll begin with a summary of the new corporate tax rate, renewable energy tax credits, and bonus depreciation, and end with a before/after comparison of the Bill on a corporate solar PV project.
To put this in perspective, we’ve run a hypothetical, corporate, rooftop solar PV system to compare the impact of reducing the federal corporate income tax rate to 21 percent and increasing the bonus depreciation to 100 percent. Only the federal tax rate and bonus depreciation have been modified in the financial model, with all other factors/assumptions being equal in the two scenarios.
*Note how the new rules extend the after-tax Payback Period relative to the old rules. This is due to the interplay between the different depreciation methods and corporate rates as pointed out previously. The benefit of the lower tax rate eventually begins to show as the spread between the IRRs turns positive.
The results of the Tax Reform Bill will vary by project based upon utility/supplier energy rate schedules, net energy metering structures, owner’s ability to efficiently utilize tax benefits, available state/local/utility incentives, geographical location and associated solar irradiance, and many other factors that ultimately affect the project’s cash flow and economic viability.
