DOE looks to make microgrids ‘essential building blocks’

Oct. 28, 2022
The US DOE plans to issue a road map for microgrids to become a pivotal part of the future grid.

The US Department of Energy (DOE) is working on six strategies to make microgrids “essential building blocks” of future electric delivery.

The strategies are explained in a series of draft white papers being floated by the Office of Electricity Microgrids R&D (MGRD) Program.

With the intent to ultimately create a microgrid road map, the DOE is seeking comment from the public on the white papers by Nov. 24.

The first paper, an overview of the strategy, says that distributed energy resources (DERs) may make up 30%-50% of electricity generation capacity in 10 years, up from 15% today. 

That many DERs cannot readily be integrated into the existing grid, which is based on centralized architectures. Microgrids, however, can help.

“One option to effectively integrate the increasing number of distributed assets, while simultaneously increasing reliability and resilience, is to use microgrids as a fundamental building block of system planning and operations,” the paper said.

With the overarching goal of improving energy resilience, decarbonization and cost reduction, microgrids will operate in various control architectures to support the bulk power grid, achieve local economic and operational objectives, and support critical end-use loads where the grid is not available, the paper said. 

At this point the impact of microgrids is still small. They make up 0.2% of electricity. But they experienced significant growth in recent years — from relatively flat growth in 2013-2016 to growth of 62%-68% per year from 2016-2019, according to the paper. Citing Guidehouse, the paper said global microgrid capacity is expected to reach 19,888.8 MW by 2028, up from 3,480.5 MW in 2019. 

The DOE plans to create a research and development program that will initially benefit single microgrids. But over the longer term — about 10 years — the program will focus more on networked microgrids and their role on the grid.

The white papers look at the gaps and opportunities for the technology with a 10-year timeframe. The papers and their lead authors are:
