MPower advised that its 1.5MWh grid connected battery storage project in NSW has successfully achieved its final acceptance milestone with Endeavour Energy. Final acceptance follows stringent field-testing and provides significant validation of the solution for other potential operators and implementation into MPower's Build Own Operate (BOO) portfolio of up to twenty 5MW renewable energy projects that will have an estimated value of more than $150 million. Following test work undertaken across two summer periods, the battery storage project has achieved its objectives of reducing network capital costs, augmenting grid capacity, and improving quality of supply and network reliability.
