Senator Peter Welch, D-Vt., introduced S. 5159 in the U.S. Senate on July 29, 2026. The bill carries the name STRONG GRID Act of 2026. It would direct $700 million toward microgrids. The money splits two ways. The Department of Energy would run a $200 million competitive pilot. States would share $500 million in energy program grants.
Welch is the ranking member on the Senate Agriculture Subcommittee on Rural Development, Energy, and Credit.
What the Bill Would Fund
DOE would stand up the pilot within one year. Competitive grants would go to projects that show four microgrid capabilities.
The first is ancillary grid services plus supply and demand management. The second pools distributed energy resources into virtual power plants. The third shifts load to relieve transmission congestion. The fourth handles voltage instability or voltage collapse.
The $500 million for state energy program grants covers four uses. A state could pay for a microgrid needs assessment or a feasibility study. It could fund design and engineering work. It could build a microgrid plus its generation and storage assets. It could also install advanced cybersecurity systems.
The bill would also make microgrids and distributed energy resources eligible under state energy program grants. It would set up state-run grid resilience programs.
Who Is Backing It
Six groups endorsed the bill in the July 29 announcement from Welch. They are the National Association of State Energy Officials, the GridWise Alliance, the National Electrical Manufacturers Association, the National Association of Electrical Distributors, Honeywell Technologies, and the Information Technology Industry Council.
Peter Ferrell is senior director of government relations at NEMA. He told Utility Dive that the trade group backs the bill for reasons beyond its provisions. National grid debate has centered on the macro grid for four to five years, he said. Microgrids moved closer to the center of that debate as large loads such as data centers queued for interconnection. Welch said the grid is “under more pressure now than at any point in our history.”
Why It Matters
The four pilot capabilities read like a list of the problems that large loads create. Voltage collapse, transmission congestion and demand management are the reasons data center studies now stretch for years. A microgrid that serves its own load frees capacity for the next customer in the queue.
That is the argument NEMA and GridWise are making. It also explains why an equipment trade group lobbies for a resilience bill.
What Has to Happen Next
Read the number in context. At $700 million, this is a demonstration budget, not a build-out budget. One utility-scale gas plant costs more.
The bill also sits at the introduction stage, which is the weakest stage. The press release from Welch named endorsing groups but named no Senate cosponsors. Authorized money still needs an appropriation before a state office can spend it.
Buyers who weigh microgrids in 2026 or 2027 should plan around existing state programs. Treat STRONG GRID money as a possibility, not a line item.
Critical Perspective
The bill authorizes money but does not appropriate it, and that distinction decides whether any of this reaches a substation. The $200 million pilot also has to clear a solicitation before a first grant lands, and the text gives DOE a full year just to stand the program up. The state channel carries a second problem the bill does not solve. State energy offices are the same agencies already administering formula funds, and adding microgrid eligibility does not add staff who can evaluate microgrid engineering. The July 29 release from Welch named six endorsing trade groups and no Senate cosponsors. Read that as the honest measure of where this bill sits today.
