The grid services project at Wheatridge addresses the challenge of integrating renewable energy sources into the power grid while maintaining stability and reliability. The project demonstrates mixed grid-forming (GFM) and grid-following (GFL) technologies at the Wheatridge Renewable Energy Facility, fostering collaboration between grid engineers and inverter vendors to enhance grid stability and encourage the adoption of grid-forming capabilities by utilities.

This work was announced under DOE’s Solar and Wind Grid Services and Reliability Demonstration Funding Program | Department of Energy PGE. DOE’s Solar Energy Technologies Office (SETO) provided $4.5 million over three years.
