UPDATE: This bill was signed into Maryland law on May 4, 2017 with a $75,000 maximum credit for commercial systems. A previous version of the bill offered credits to commercial systems up to $150,000.

In April, the Maryland legislature passed a bill creating a state income tax credit for the costs associate with installing an energy storage system. Governor Larry Hogan is expected to sign it into law. Unlike measures in other states such as California and Massachusetts, the Maryland bill does not contain mandated amounts of energy storage that utilities must procure. Instead, if the current bill is signed, Maryland will be the first state in the country to incentivize the deployment of energy storage systems by offering a tax credit. Presently, an energy storage system can qualify for the federal investment tax credit if it is installed alongside a solar photovoltaic system. This is the first ever tax credit for storage-only projects, although qualified energy storage systems still may be paired with renewable energy projects.

Under the terms of the bill, a taxpayer will receive a credit equal to 30 percent of the installed costs of the system, not to exceed $5,000 for a residential system or $150,000 for a commercial system. The incentive program has a funding cap of $750,000 per year, and applications for the credit will be approved on a first-come, first-served basis. Additionally, the tax credit may not be carried over for use in future tax years. The tax credit is currently slated to run from 2018 to 2022.
