The project is the inaugural application of Earthrise’ surplus interconnection strategy. Through this approach, 270 MW of new solar generation can utilise the existing grid infrastructure of Earthrise Energy’s Gibson City natural gas-fired peaking facility. The model provides renewable energy to the grid when available, while maintaining the reliability benefits of fast-start generation capable of responding during periods of peak demand.
“We believe the successful commercial operation of Archtop validates our model that can help address one of the most significant challenges facing the energy industry today: how to bring new generation online fast enough to meet growing demand” said Jeff Hunter, Chief Executive Officer of Earthrise Energy. “Illinois needs additional energy resources now, and this project demonstrates that innovative use of existing infrastructure can accelerate deployment timelines while supporting Governor Pritzker’s vision for a clean and reliable energy future. We believe this approach has the potential to serve as a blueprint for future development across the region.”
The project demonstrates a practical pathway for supporting Illinois and the Midcontinent Independent System Operator (MISO) region by bringing new generation online more quickly than traditional greenfield development. Rather than entering the lengthy, traditional interconnection queue typically required for new generation resources, Earthrise Energy secured an interconnection agreement through the surplus interconnection process offered by MISO. By making efficient use of existing infrastructure, Earthrise Energy believes similar projects can help accelerate the addition of reliable, lower-carbon generation to the grid.
“Our concept working as intended is a significant milestone for Earthrise and validates the work we’ve put into developing this model” added Scott Halleran, Vice President of Asset Management for Earthrise Energy. The early operating results reflect the type of coordination this model was designed to enable: solar generation when available, and peaker generation when other outputs decline and peak demand increases. We’re proud that our facilities are actively supporting MISO, generating energy through differentiated means.”
Earthrise is actively developing a ~1.5 gigawatt pipeline through five solar projects across Illinois that seek to leverage this approach to quickly delivering stable renewable power to the grid. The projects include Northwest and Glacier Moraine Solar in Cumberland and Coles Counties, Plum Valley and Pride of the Prairie Solar in Will County and Tilton Solar in Vermillion County.
