Why This Matters for Rural Electric Co-ops

This article profiles three federally funded microgrid projects in rural communities, with the details a co-op needs to judge whether a similar project fits: site sizing, backup duration, cost share, and the criteria NRECA used to narrow 25 interested co-ops down to seven funded communities. The DOE ERA program is now closed to new applicants, so the article is not a funding lead. Its project details may still help co-ops that already hold awards as well as co-ops weighing microgrids with other funding.

Each project shows a different model: a state office installing solar and storage at town facilities, a municipal utility islanding a whole town, and a national co-op consortium. The article also names the consortium communities, including Clinton and Cooke City in Montana and the Shakopee Mdewakanton Sioux Community in Minnesota, which can point a co-op toward peers doing similar work. The Wisconsin sites offer a useful reality check, since each provides up to three hours of backup. That is far short of what members may picture when they hear "microgrid" during a multi-day rural outage.


Key Takeaways

ERA funded solar-plus-storage microgrids in communities of 10,000 or fewer, in some cases paired with advanced metering, EV chargers, and distribution upgrades.
NRECA picked its seven consortium sites based on replicability, location in disadvantaged communities, innovation, and tribal engagement. That gives co-ops a model for pooling smaller projects into a competitive bid.
Small critical-facility microgrids offer limited backup (up to three hours per Wisconsin site). Co-ops should set member expectations to match actual duration, not the word "microgrid."
Awardees stacked grants with federal tax credits through direct pay. These credit terms have since changed and need fresh review before anyone relies on them.

Implementation Considerations

  • Cost or Funding Requirements: ERA funding is not available to co-ops without an approved award, and new applicants should not rely on this pathway. Awardees also covered a local cost share of roughly 20% or more. Any co-op following this model needs another funding source and a clear local match.
  • Staffing or Technology Requirements: Microgrids involve design, permitting, interconnection, procurement, and controls work spread over several years. Smaller co-ops will likely need outside support from organizations, consultants, or peer co-ops. Joining a consortium, as these co-ops did, is one option.
  • Time-Sensitive Information: The funding and tax credit details in the article have changed since it was published, so treat its figures as historical.

Notable Examples

  • NRECA: Led a seven co-op consortium selected for $45.2 million for microgrids in rural communities.
  • Wisconsin Office of Sustainability and Clean Energy: Installing solar and batteries at 24 critical facility sites in Bayfield County as community resilience hubs.
  • Montezuma Municipal Light & Power: Municipal utility building a solar and battery storage microgrid that can island the town.
