California PUC sets energy storage target for utilities of 1,325 MW by end of 2024

18 October 2013

The California Public Utilities Commission (CPUC) established a combined energy storage target of 1,325 megawatts (MW) for Pacific Gas and Electric Company, Southern California Edison, and San Diego Gas & Electric by 2020, with installations required no later than the end of 2024. (MW represents the peak power capacity of the storage resource in terms of the maximum discharge rate.)

The decision, pursuant to Assembly Bill 2514, directs the utilities to file separate procurement applications containing a proposal for their first energy storage procurement period by 1 March 2014.

The decision further establishes a target for Community Choice Aggregators and electric service providers to procure energy storage equal to 1% of their annual 2020 peak load by 2020 with installation no later than 2024, consistent with the requirements for the utilities.

Starting on 1 January 2016, and every two years thereafter, community choice aggregators and electric service providers must file a Tier 2 Advice Letter demonstrating their compliance towards meeting the target and describing their methodologies for cost-effective projects.

The guiding principles of the decision were:

  1. the optimization of the grid, including peak reduction, contribution to reliability needs, or deferment of transmission and distribution upgrade investments;

  2. the integration of renewable energy; and

  3. the reduction of greenhouse gas emissions to 80% below 1990 levels by 2050, per California’s goals.

OK, 1325 Mw,
How many MwH ?

LOL, the CPUC is sure screwed up. At the start they are accurate enough in specifying the peak power capacity of the storage resource in units of MW, however later on, in the schedule itself, they refer to it as the energy storage procurement ??

Which is all somewhat meaningless unless the expected backup time is quoted.

If the existing thermal stations could have their load factors increased during the night in order to replenish these proposed energy storage devices we could probably avoid the huge expense of natural gas turbine peak lopping plants and the arbitrary contributions from those boutique energy sources of photovoltaics and wind.
