Solar Facility

Mammoth Community Water District’s (MCWD) 1 MW (Megawatt) solar facility came online in October, 2011 after a full year of construction and years of planning. MCWD’s solar array produces up to 2 Million kWh (kilowatt-hours) of solar power every year, meeting or exceeding the power demands of the wastewater treatment plant (WWTP). The footprint for the solar arrays was reclaimed from a deprecated portion of the original MCWD WWTP. The solar panels are designed with carefully engineered supports to withstand the high winds, snow loads, and extreme weather that Mammoth Lakes is known for, while following the sun to maximize solar energy production year-round. All of these hard working panels are on track to pay for themselves by 2022 and by 2037 will have produced nearly 50 Million kWh of clean, renewable energy. This is the equivalent of taking almost 5,000 cars off the road for a year.
