What is Connecticut’s Microgrid Program?

Under Public Act 12-148, Section 7, Connecticut created a Microgrid Program to help support local distributed energy generation for critical facilities. This act required the Department of Energy and Environmental Protection (DEEP) to establish a pilot of the Microgrid Program. It was created as a result of multiple episodes of severe weather that caused widespread power outages for extended periods and is designed to help create ways to ensure that critical buildings remain powered during electrical grid outages.

Under the Microgrid Program, grants were awarded recipients to support critical facilities and were generally split between small, medium, and large municipalities if possible. Critical facilities, as defined by Public Act 12-148, Section 7 are “any hospital, police station, fire station, water treatment plant, sewage treatment plant, public shelter or correctional facility, any commercial area of a municipality, a municipal center…”

In 2016, the program’s bond funding was expanded to provide matching funds or low-interest loans for an energy-storage system or clean distributed-generation projects for a Microgrid.

What is a Microgrid?

A microgrid is a local energy grid with control capabilities that allows the grid the ability to disconnect from the traditional grid, which is the central power source that supplies power to the buildings and homes in a very large area. A microgrid can operate in both grid-connected and island mode.

A microgrid generally operates while connected to the grid but can disconnect and operate in island mode on its own if there is a crisis such as a power outage or a major storm. The microgrid will then use its own local energy generation from renewable sources, fuel cells, batteries, or fossil fuels to supply power to the nearby buildings until the main grid is stable enough to reconnect.

Previous Rounds: Award Winners and Updates

On July 24, 2013, Governor Malloy announced the awardees of the first-in-the nation statewide Microgrid Pilot Program. During the announcement, he stated that the nine microgrid projects were “awarded a total of $18 million in funding primarily through the DEEP Microgrid Pilot Program.” Governor Malloy then recommended, and passed in conjunction with the legislature Public Act 13-298, which authorized an additional $30 million in funding for the Microgrid Program to expand microgrids to other Connecticut communities over the next two years.  Projects that were not funded in the Pilot Round were encouraged to participate in future rounds of funding.

On March 6, 2014, Wesleyan University in Middletown started the first CT microgrid  as a result of the grant funding. Wesleyan’s microgrid connects existing generation to critical facilities on campus and has the ability to go into island mode to power the critical facilities in an event of a power failure.

DEEP issued a request for proposals for Round 2 of the Microgrid Program in March 2014. Of the five proposals submitted for Round 2, two were awarded grants totaling approximately $5.1 million.

DEEP issued a request for applications for Round 3 of the Microgrid Program in November 2015. Of the four applications submitted for Round 3, one was awarded a grant totaling for $424,000.

DEEP issued a request for applications for Round 4 of the Microgrid Program in August 2017. Of the nine applications submitted for Round 4, three were awarded grants totaling approximately $13.1 million.
