    Another Big Step For Big Energy Storage

    Tesla strikes another mammoth energy storage deal in California; Lithium-ion battery projects are becoming economically viable.

    Megan Geuss, July 2, 2018 (Ars Technica)

    “…[Dominant] California utility Pacific Gas and Electric (PG&E) asked the state to approve four lithium-ion battery storage projects…[A 730MWh to 1.1 GWh project, built by Tesla, would be owned and operated by the utility. It] is expected to discharge 182.5MW for 4 hours (hence, the 730MWh number). But the contract could be bumped up to a discharge duration of 6 hours, which would result in just under 1.1 GWh of storage owned by PG&E…

    [Another project, to be developed by Vistra (which recently merged with Dynegy) and completed by 2020,] could become the world's first grid-scale, lithium-ion battery installation to store more than a gigawatt-hour of energy…[The 300MW battery installation] would be able to be discharged for four hours. At 1.2GWh, the battery would be among the largest in the world…The two other projects are smaller and include a 75MW / 300MWh battery installation from a company called Hummingbird Energy Storage LLC, as well as an aggregation project from Micronoc Inc, which will site 10MW / 40MWh of batteries at commercial locations…” click here for more
