December 5 (Renewables Now) - California utility Pacific Gas and Electric Co (PG&E) has awarded contracts to six energy storage projects, all lithium ion batteries, totalling 165 MW.

The list includes three projects of Italy's Enel SpA (BIT:ENEL) with a combined capacity of 85 MW/340 MWh, it was announced Monday.

The six contracts were awarded following a competitive solicitation process as part of PG&E's efforts to procure 580 MW of energy storage capacity by 2020, in line with a requirement for California investor-owned utilities to procure a total of 1,325 MW of storage by that year.

PG&E has submitted the six storage contracts to the California Public Utilities Commission (CPUC) for review and approval. "These contracts and the storage capacity they represent will help us better integrate our growing renewable generation sources, and bring increased reliability to the grid," said Martin Wyspianski of PG&E.

In a separate statement, Enel said the contracts will expand its energy storage portfolio. "The signing of these agreements marks an important step forward in our Group’s plan to strengthen its presence in the energy storage market and expand this business in the US, and California in particular, which are at the forefront in the development of this market," said Enrico Viale, head of Enel Global Thermal Generation.

Enel's three projects -- the 50 MW/200 MWh Kingston, 25 MW/100 MWh Cascade and 10 MW/40 MWh Sierra -- are developed with independent developer Sovereign Energy Storage and are expected to be operational by 2023.

Below is a list of all six projects as provided by PG&E:
