A retirement community in California is set to install a solar+storage system that is expected to save over $250,000 per year in energy and demand savings.  

The 240 kW/324 kWh behind-the-meter energy storage system from Sharp Electronics’ Energy Systems and Services Group (ESSG) will be installed in six buildings on the grounds of the Paradise Village retirement community (pictured) in the city of San Diego.

It will be integrated with an existing 516 kW solar PV system installed by Oregon-based solar firm NW Photon Energy.

Paradise Village is a multi-building community which includes independent and assisted living wings as well as memory care. The complex consumes a significant amount of energy from HVAC, refrigeration and a variety of medical equipment that can have a significant startup load, which increases demand request peaks with the local utility. It is estimated that Paradise Village’s system will reduce demand by over 2 MW per year.

According to Sharp, a detailed analysis of Paradise Village’s energy use found that the energy storage system is expected to yield $90,000 per year in demand savings. When coupled with the PV system, Sharp said Paradise Village can expect to save over $250,000 per year on its utility bills.

The storage system is backed by Sharp’s ten-year Asset Management Service Agreement, which provides routine and unscheduled maintenance coupled with a ten-year demand reduction performance guarantee. If guaranteed peak demand reductions are not met within the terms of the agreement, Sharp said, it will compensate the system’s owner for the deficit.

Carl Mansfield, founder and general manager of Sharp’s ESSG, said: “The significant savings unlocked by addressing peak demand may have a positive impact on the quality of life for the seniors in Paradise Village’s care, so we’re very proud to be involved in this project.

“In addition to this retirement home, we’ve now had storage systems installed at a wide variety of facilities such as lumber yards, non-profits, service stations, school campuses, manufacturing plants and more.

“This demonstrates how economically impactful our energy storage system can be for virtually any commercial and industrial building that is struggling with high utility bills that are punctuated by expensive demand charges.”
