Viridi has deployed its fail-safe BESS – RPSLinkEX – at Denver Public Library, marking the city’s first integrated solar and battery storage installation for a public facility.
Delivered in partnership with McKinstry, the project reflects Denver’s broader commitment to sustainability and grid resilience.
Unlike conventional lithium-ion systems, Viridi’s fail-safe BESS technology incorporates proprietary anti-propagation safeguards that eliminate the risk of thermal runaway. The company says that this makes it one of the safest BESS options for occupied buildings. The behind-the-meter system captures excess solar energy, reduces peak demand, and provides backup power during outages, all while meeting Denver’s stringent fire safety codes.
The library required a solution that balanced environmental performance with operational safety. RPSLinkEX meets those demands, offering reliable energy storage without compromising public safety or infrastructure integrity.
“Public facilities like the Denver Public Library are at the forefront of demonstrating that energy resilience and safety can go hand in hand,” said Jon M. Williams, CEO at Viridi. “This installation highlights how fail-safe battery storage can empower communities to maximise renewable energy, reduce costs, and maintain reliability – all without compromise.”
The system is fully integrated into the library’s infrastructure and monitored via Viridi’s ViSTA Dashboard.
