PG&E seeks approval for six energy storage projects

California utility Pacific Gas and Electric Company (PG&E) has submitted six energy storage contracts to the California Public Utilities Commission for approval. The contracts are part of its efforts to meet the state-mandated goal of adding 580 MW of storage capacity by 2020. If these contracts are approved, PG&E will reach 42 per cent of the targeted capacity. The contracts have been awarded to companies including Tesla, Enel Green Power and EDF Renewable Energy. The energy storage systems will be based on lithium-ion battery technology and will range from 1 to 50 MW. The first project is planned to come online in November 2020. All the storage projects must be operational by 2024. Meanwhile, the utility has stated that around 33 per cent of its retail electric deliveries will come from renewable sources by end-2017.
