Regional San constructed a solar energy array at the EchoWater
Resource Recovery Facility. The solar array is one of the
largest located at a wastewater treatment plant in the nation.
The solar array offers a clean and sustainable energy source with
several benefits.
The project is administered through a power purchase agreement
with Tesla, who constructed and owns the facility.
Beginning in 2018, all the power generated from the system will
be sold to Regional San at a fixed rate for 25-years.
This solar array increases and diversifies our green energy
portfolio, provides a clean and sustainable energy source, and
brings financial benefits by reducing energy costs. The estimated
savings to Regional San over the 25-year period is about $10
million. The solar array also meets environmental requirements
for greenhouse gas mitigation as part of the EchoWater Project,
The 4.2 megawatt solar array has a footprint of approximately 21
acres of open space designated for future treatment processes. It
will produce approximately eight percent of Regional San’s
current energy needs which is enough to power approximately 750
homes annually.
