SA Water set out to achieve a net zero energy cost across all assets by 2020. As South Australia’s largest provider of water and sewerage services, SA Water serves 1.6 million people across the state. Its energy intensive operations previously consumed 220 GWh. To reach its ambitious goal, SA Water nominated 93 assets to install Solar PV, with 71 of those to also get a Battery Energy Storage System (BESS). The required solar power and BESS capacity were 200MW and 39MWh to yield sufficient electricity to meet its goal.
All sites were to be monitored and controlled from a central location, to make use of energy market spot price fluctuation and to be able to align the individual site operations to energy cost and availability.
John Holland Group engaged CNF to prepare the tender design for their submission.
