Town of Danville Energizes Solar Carport Canopy and Battery Microgrid at Oak Hill Park

Town of Danville Maintenance Services engineers and Pacific Gas and Electric interconnection specialists energized a 240-kilowatt solar photovoltaic carport canopy and battery storage microgrid on Friday morning at Oak Hill Park at 3005 Stone Valley Road. Authorized by the Danville Town Council under the municipal Climate Action and Resiliency Plan, the steel-framed canopy spans eighty-six visitor parking stalls adjacent to the Oak Hill Park Community Center and Monte Vista High School aquatic complex. In addition to shading parked vehicles during summer tournaments, the overhead array will generate an estimated 385,000 kilowatt-hours of emission-free electricity each year.

Electricity produced by the bifacial solar panels feeds directly into a 430-kilowatt-hour lithium-iron-phosphate battery enclosure located behind the park maintenance yard, offsetting nearly 92 percent of annual utility charges for the community center, irrigation booster pumps, and evening athletic field lighting. Town financial analysts project that reduced peak-demand charges will save Danville taxpayers roughly $78,000 per year over the twenty-five-year warrantied lifespan of the installation.

When the Oak Hill Park Community Center is activated as a regional cooling or clean-air respite center during summer heat waves or Public Safety Power Shutoff events, the microgrid controller automatically islands the building from the broader distribution grid. That islanding capability guarantees uninterrupted power for HVAC filtration, medical device charging outlets, refrigeration, and emergency radio repeaters for up to forty-eight hours without backup diesel generation.

The $1.12 million capital project incorporated $340,000 in federal clean-energy direct-pay investment tax credits and California Self-Generation Incentive Program rebates. Residents can view live solar generation telemetry and town facility sustainability benchmarks on the Town of Danville Clean Energy Portal or at the display monitor inside the Oak Hill Park Community Center lobby.
