Pleasant Hill and MCE Energize 500-kWh Battery Microgrid at Chateau Lane Community and Senior Center

City of Pleasant Hill public works engineers, Pleasant Hill Recreation and Park District administrators, and clean-energy specialists from MCE commissioned a 500-kilowatt-hour lithium-iron-phosphate battery storage microgrid on Saturday morning at the Pleasant Hill Senior Center and Community Resilience Hub at 233 Gregory Lane and Chateau Lane. Designated by Contra Costa County Office of Emergency Services as a primary central-county warming, cooling, and clean-air respite center, the 22,000-square-foot facility previously relied on a portable diesel generator that could power only emergency hallway lighting during winter storm grid outages or Public Safety Power Shutoffs.

Integrated directly with the building's existing 165-kilowatt rooftop solar array, the new outdoor modular battery enclosure and automatic transfer switch detect utility voltage sags in under twenty milliseconds, seamlessly islanding the entire building without blinking interior lights or dropping Wi-Fi connections. While operating in islanded mode, the solar-and-battery microgrid can sustain full main-hall HVAC climate control, commercial kitchen refrigeration for senior Meals on Wheels distribution, automatic ADA entry doors, and forty dedicated medical-device charging stations for up to seventy-two hours.

During normal blue-sky grid operations, MCE's automated Virtual Power Plant software dispatches stored solar electricity from the battery between 4:00 PM and 9:00 PM each evening when California's electric grid relies most heavily on natural gas peaker plants. That daily peak-shaving cycle is projected to trim the Pleasant Hill Recreation and Park District's utility bills by $34,000 annually over the next twenty years.

The $690,000 microgrid installation was funded at zero local taxpayer cost through MCE's Energy Storage Program and the California Public Utilities Commission Self-Generation Incentive Program Equity Resiliency budget.
