The battery system, Viridi’s RPSLinkEX, incorporates fail-safe anti-propagation technology to meet strict fire-safety standards for occupied public buildings. It comes with a 10-year warranty on battery cells and a 2-year warranty on other components. The project benefited from federal incentives, including a 30% Investment Tax Credit and an additional 10% Domestic Content adder, covering up to 40% of the installed cost.
This behind-the-meter system captures excess solar energy during the day and discharges it after hours to shift electricity usage to lower-cost periods and reduce peak demand charges. For the library, which is on XCEL’s Secondary General rate tariff with demand charges around $25/kW, the 20 kW battery energy storage system can
