UPDATE: Governor Larry Hogan issued an executive order​ on March 12th mandating teleworking for non-essential state employees across all state agencies in response to COVID-19.  During this time, the Maryland Energy Administration (MEA) energy storage tax credit program staff can be reached via email at Information submitted to MEA by postal mail may have processing times affected by the office closure.  We apologize for any inconvenience this may cause and we appreciate your understanding. ​​

MEA is pleased to announce the launch of the Tax Year 2020 Maryland Energy Storage Income Tax Credit Program (the program). The program is designed to encourage the deployment of energy storage systems in Maryland.

The program is available to residential and commercial taxpayers who have installed an energy storage system on their residential or commercial property in Maryland during Tax Year 2020 (January 1 - December 31, 2020).  Under the enabling statute, MEA may award a total of $750,000 in tax credit certificates during a given tax year. Tax credit certificates will be awarded to eligible applicants on a first come, first served basis during Tax Year 2020. To comply with the enabling statute, under no circumstances will more than $750,000 in energy storage income tax credit certificates be awarded for a single Tax Year. Current law authorizes MEA to offer this program for Tax Years 2018, 2019, 2020, 2021, and 2022. More information can be found in the program TY 2020 Energy Storage Tax Credit Revised Notice of Availability (NOA).

As of January 5, 2021, the program has $278,896.49 available for residential and commerical tax credit certificates. This is equal to 37.2 percent of the total tax credit allowance for Tax Year 2020.

The Energy Storage Tax Credit Program utilizes an online application. Click the link below to begin your application.

Energy storage tax credit certificates are calculated differently for systems installed on residential and commercial properties. A tax credit certificate is calculated as the lower amount of:

  • 30 percent of the total installed costs of the energy storage system; or,

  • $5,000 for an energy storage system installed on a residential property; or,

  • $150,000 for an energy storage system installed on a commercial property.

The Program is open to the following taxpayers that have leased an energy storage system:
  • An individual or a corporation that owns or pays for the installation of an energy storage system that supplies electrical energy intended for use on the residential or commercial property on which the energy storage system is installed.

Commercial Property means nonresidential property with a commercial, industrial, or government use as outlined in the definition for the “Commercial Clean Energy Grant” in COMAR and includes multifamily properties.

Residential Property means property, including a single-family home and an individual unit of a multifamily property or mixed use facility, that has the purpose of serving as a primary residence, as outlined in COMAR (18).

  • Electrical energy;
  • Mechanical energy;
  • Chemical energy (including electrochemical energy); and,
  • Thermal energy that was once electrical energy.

System Use

All energy storage systems must store energy for the following purposes:

  • for use as electrical energy at a later date; or,
  • in a process that offsets electricity use at peak times.
