The role of microgrid energy storage systems in the United States

Are microgrids the future of energy resilience?

Microgrids are poised to play a large role in the future of energy resilience in the U.S. electric system. However, these systems face financial and regulatory barriers in many states. Several states have already taken steps to enable new financing tools and improve regulatory processes.

How does government support microgrids?

Support for microgrids comes from research and development (R&D) programs at federal and state levels, software and tools, grants and funding support to incentivize demonstration projects, and tax and financial incentives for the installation of distributed energy , , , .

How do microgrids work?

During normal conditions, microgrids operate harmoniously while tied into the larger power grid, using distributed energy resources (DERs) to offset energy needs and reduce consumption from the local utility—not dissimilar conceptually from rooftop solar installations.

What are the benefits of a microgrid?

benefits above and beyond energy resilience benefits: Microgrids that incorporate renewable energy resources can have environmental benefits in terms of reduced greenhouse gas emissions and air pollutants. In some cases, microgrids can sell power back to the grid during normal operations.

Are microgrids a solution to power outages?

Microgrids are often pitched as solutions to power outages, but their advantages extend beyond just emergency applications. Microgrids can also support the larger grid by providing energy and ancillary services while grid-tied, or act on-demand response signals when the larger grid is under stress.

What is a microgrid system?

Microgrids are electricity distribution systems containing loads and distributed energy resources (such as distributed generators, storage devices, or controllable loads,) that can be operated in a controlled, coordinated way either while connected to the main power network or while islanded.
