The AESC team was invited to this drinking water treatment facility to perform a detailed integrated energy audit on behalf of PG&E. AESC was tasked with identifying and quantifying energy efficiency, load management, and demand response measures. These efforts were developed into a detailed report which included associated savings, project cost, and available incentives for a number of potential projects including lighting controls, LED retrofits, compressed air retrofit, electric resistance heater replacement, and a gas engine replacement.
