A combined heat and power (CHP) system at the Toledo Museum of Art in the US state of Ohio has surpassed 400,000 hours of operation, microturbine supplier Capstone Turbine and energy services firm GEM Energy, a Capstone distributor, have announced.

The system’s four C65 microturbines supply the museum with 260 kW of power and 1.6 million btu of heat. When installed in 2003, the system (pictured) was Ohio’s first microturbine installation and the state’s first to include a net metering agreement with local utility First Energy.

The Toledo Museum of Art’s sustainability programme is seen as a model for other museums, arenas and large facilities that require significant amounts of energy, the companies said. The museum’s two-story, 250,000 square foot (around 24,000 square metres) building includes 45 galleries, 15 classroom studios, a 1750-seat concert hall, a 176-seat lecture hall, a café and a boutique.

The CHP system allows the museum to conserve energy while maintaining the temperature and humidity levels required to preserve its art collection.
