Case Study: Xcel Energy manages rooftop solar growth with Sunverge distributed battery storage

Xcel Energy manages 6-home rooftop solar storage with Sunverge

Xcel Energy, a utility company, faced challenges integrating a high concentration of rooftop solar energy on its power grid in a Denver neighborhood. This led to grid issues like voltage regulation and peak demand. To address this, Xcel partnered with vendor Sunverge on a community energy storage demonstration project.

The solution implemented by Sunverge involved installing its 6.8 kW/11.6 kWh home battery storage systems on six homes with existing solar. These systems, managed through Sunverge’s cloud-based platform, can be controlled individually or aggregated as a Virtual Power Plant (VPP) to support the grid. The project aims to reduce feeder issues caused by high solar penetration, provide homeowners with backup power, and potentially delay the need for costly feeder upgrades.
