60th largest plant in Maryland · 6987th nationally
Brookville Smart Bus Depot Microgrid is a solar power plant in Maryland with a nameplate capacity of 5.0 MW. It generates roughly 2.2k MWh per year — enough to power about 207 average U.S. homes.
Its capacity factor of 5% reflects intermittent or peaking operation. At 107 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.

Utility-scale solar farms convert sunlight directly into electricity using photovoltaic panels. They produce zero direct emissions and have no fuel cost, but generation is variable — peaking at midday and falling to zero at night. Capacity factors typically run 18–28% in good locations.
