Microgrids
A microgrid is a network of local energy sources that is normally connected to the traditional grid but can also function independently as needed. The City of Dublin is in the process of installing solar panels and battery energy storage systems to create microgrids at four locations across the City, which will increase resiliency and energy savings.
- Civic Center – A new 232 kW (DC) solar panel system and 32 kW/64 kWh battery energy storage system will increase the current solar system’s capacity to meet the building’s energy demand and future planned EV charging needs. Excess electricity generation can be credited to the adjacent Dublin Sports Grounds electric bills via the Net Energy Metering Aggregation tariff.
- Corporation Yard – A 47 kW (DC) solar panel system and a 100 kW/165 kWh battery energy storage system will generate additional electricity that will offset the facility’s electricity demand and increase bill savings. The facility’s increased resiliency will also support its role as the Field Communications Center in the City’s Emergency Operations Plan.
- Senior Center – A new 38 kW (DC) solar panel system will support the building’s current system to generate additional electricity that will offset the facility’s electricity demand and increase bill savings. The facility’s increased resiliency will also support its role as an emergency operation shelter in the City’s Emergency Operations Plan.
- The Wave – A 525 kW (DC) solar panel system and a 500 kW/1100 kWh battery energy storage system will reduce overall operational costs. These improvements will also provide resiliency and electricity during extended power outages and when the Wave serves as a cooling center and shelter as part of the City’s Emergency Operations Plan.
