The energy storage market is one of the most exciting and fastest growing new industries in the utility space right now. The market grew by several hundred percent last year, and it looks likely that it will grow by a similar amount again this year.

Still, this is a market in its infancy and many market participants are still figuring out the economics. Those economics are set to get a boost thanks to an energy storage tax bill that is making its way through the U.S. Congress right now.

The bill in question is co-sponsored by Democrat Martin Heinrich from New Mexico and 8 other members of congress including Dean Heller, a Nevada Republican. Under the bill, energy storage would get the same set of tax incentives that have helped to fuel the meteoric rise of clean energy sources like solar power. That means that Lithium Ion batteries for instance would be eligible for tax incentives when used in utility grid connections at residences and businesses. Flywheels, compressed air, pump hydro, and other storage solutions would also get a tax credit.

The bill could change of course, but at present it looks like a 30 percent tax credit would be applied to energy storage provided that the storage levels meet certain thresholds. In particular, residential batteries would need to have at least 3 kwh of capacity, while commercial storage would need to have at least 5 kwh of capacity.

It is very difficult to predict what bills Congress will choose to act on, but the current bill is particularly interesting because of the existing tax credits for energy storage. At present, energy storage does qualify for a 30 percent tax credit, but that credit is subject to the IRS’ typical set of arcane regulations. In particular, the storage only qualifies for the credit if at least 75 percent of the power comes from clean energy sources rather than from the grid. Also, the storage credit is limited by the percentage of renewable input. If 90 percent of the storage charging energy is derived from solar panels, then the storage is only eligible for only 90 percent of the ITC. In other words, to get the energy storage credit, companies and individuals have to keep insane amounts of records and documentation related to their equipment and how it is used. Of course, that’s a pretty good descriptor for many of the IRS’ rules.

The current bill would greatly simplify an otherwise byzantine rule that is very difficult to follow and actually does little to promote the development of the energy storage market or on a related basis, clean energy. As a result, Congress should look at the new bill as an opportunity to clean up an existing IRS morass rather than seeing the bill as creating a new set of tax incentives. From that perspective, the bill should be much more politically palpable on both sides of the aisle.

Investors should keep an eye on the outcome of this bill – if it does pass that would be a significant boost for many of the new tech companies in the energy space. Tesla in particular would benefit significantly thanks in large part to both its energy storage business and the exposure it is taking on in the solar market through the acquisition of SolarCity.
