Microgrids and energy storage can help U.S. states assure energy supply during disasters, according to two papers recently issued by the National Governors Association (NGA).
The papers emerged from an effort NGA undertook last year to identify best energy practices that have emerged from Superstorm Sandy.
A six-state team studied lessons learned from New Jersey after being pummeled by the storm in 2012. The teams, from Hawaii, Maryland, Michigan, North Carolina, Oklahoma and Rhode Island, then went on to create action items to guide their own state efforts.
The action items are described in the paper, “Improving State Coordination for Energy Assurance Planning and Response.”
Among other things, the states are exploring the feasibility of using microgrids and other forms of distributed energy resources, creating robust energy plans, improving utility/government communications, and cataloging critical energy assets.
For example, Rhode Island is working to identify microgrid sites as part of a statewide program, according to the report. The New England state is funding the microgrid effort with a grant from the U.S. Department of Housing and Urban Development and proceeds from the Regional Greenhouse Gas Initiative (RGGI).
The report also noted that as a result of Sandy, NJ Transit is developing a microgrid to power the transit system during outages, NJ Transit, the nation’s third largest provider of bus, rail and light rail transit, is partnering on the project with New Jersey Board of Public Utilities (BPU), the U.S. Department of Energy and the Federal Transit Administration.
