The increasing electricity demand in the U.S. necessitates cost-effective solutions for power generation. Surplus Interconnection Service (SIS) allows for faster integration of new power generation or storage by using surplus capacity at existing plants, circumventing lengthy interconnection queues.

Established in 2018 by the Federal Energy Regulatory Commission for plants over 20 MW, SIS facilitates the addition of resources such as solar and batteries. This method boosts energy delivery, minimizes land use, enhances reliability, reduces grid congestion, and lowers transmission costs. State governments can promote SIS to enhance grid capacity efficiently.
