Adelaide, South Australia, water utility SA Water is planning to achieve net-zero electricity costs by building a solar portfolio paired with energy storage.

The utiity yesterday said it will install 152 MW of solar PV generation and 35 MWh of energy storage across about 70 locations over the next two years. SA Water added that it spent $55 million on electricity in 2016-2017.

“Locating generation behind the meter will improve our resilience to grid interruptions, significantly reduce our network charges and isolate our business from electricity market price volatility, in both the short and long-term,” SA Water Chief Executive Roch Cheroux said. “The maturity of solar technology has allowed us to confidently determine how and where it can assume supply for our energy-intensive water treatment and pumping operations, and export to the market to return revenue.”

The utility said it will focus on placing the solar arrays in operation first, and then select and acquire storage based on a series of thermal, flywheel and battery trials currently being performed by project partners.

“We’re now looking to hear from experienced and capable suppliers who can help deliver arrays ranging in size from 100 kW to 13 MW, at metropolitan and regional locations,” Cheroux said.

An initial Expression of Interest with guidance for prospective vendors is available through the South Australian government.
