Irvine Ranch Water District (IRWD) – Battery Energy Storage Systems, US

By Carmen

The Irvine Ranch Water District (IRWD) – Battery Energy Storage Systems is a 7,000kW energy storage project located in Irvine, California, US.

The electro-chemical battery energy storage project uses lithium-ion as its storage technology. The project was announced in 2016 and was commissioned in 2018.


The Irvine Ranch Water District (IRWD) – Battery Energy Storage Systems was developed by Advanced Microgrid Solutions. The project is owned by Macquarie Capital (USA) (100%), a subsidiary of Macquarie Group.

The key applications of the project are demand response, electric bill management and electric supply capacity.

Contractors involved

Advanced Microgrid Solutions, Macquarie Capital (USA) and Tesla have delivered the battery energy storage project.

Additional information

The 7 MW / 34 MWh BESS will utilize Tesla batteries, installed at 11 of IRWD’s largest and most energy-intensive facilities, including three water treatment and recycling plants, a deep aquifer treatment system, a groundwater desalter facility and six high-energy pumping stations, as part of a major grid modernization project for Southern California Edison (SCE). The energy storage systems will be linked together as a network providing IRWD facility managers real time visibility and operational flexibility in responding to utility requests for demand reduction. IRWD expects to see cost savings of more than $500,000 per year on its energy bill. The IRWD-AMS Project is supported by a 10-year power-purchase agreement with Southern California Edison Company.
