Funded by a PPA, it’s anticipated to avoid wasting the Monterey County Sheriff’s Workplace, which operates the jail, greater than $12 million over its lifetime.
The set up features a 1.243-MW carport photo voltaic array paired with a 1.043-MW/2.087-MWh Tesla battery system and is anticipated to generate greater than 2,000 MWh of unpolluted electrical energy yearly. This can offset roughly 55% of the County Jail’s annual power use.
