Maryland finalizes changes to distributed generation engine regulations.

February 27, 2018

On February 2, 2018, the Maryland Department of the Environment (MDE) published the final revisions to Maryland’s distributed generation regulations codified in the Maryland Register according to a February 20, 2018 Trinity Consultants report.

The changes align Maryland’s definitions of “emergency engine” and “nonemergency engine” with federal regulations and repeals state-only emissions requirements for engines. The updated regulations are effective as of February 12, 2018.

The engines most impacted by this regulatory update are engines that participate in emergency demand response programs. Under the old Maryland regulations, these units were classified as emergency generators.

However, under the updated regulations, these units are now classified as non-emergency generators under Maryland regulations in addition to under the federal regulations. With this change, any generator participating in emergency demand response will now be required to obtain a Permit to Construct, regardless of unit size.
