The rural electric cooperatives are testing how the storage technology can help customers and their systems.
“Nobody got everything they wanted, but it advanced the cause of rooftop solar and net metering,” an advocate said.
The legislation lifts a net metering cap for cooperatives and allows their customers to install larger solar projects.
The fee is at the center of a dispute between Delta-Montrose and Tri-State, the electric cooperative’s wholesale provider.
United Power’s project has stoked tensions with its power wholesaler, which capped members’ storage capacity.
