Regulation Energy Management Overview

CPUC Energy Storage Workshop

March 9, 2011


Regulation energy management provides additional functionality to address limitations of storage resources.

  • Limited energy resources unable to participate in day-ahead regulation market at full capacity w/o REM

  • Barriers to entry still existed even with March 2010 ancillary services modifications to support non-generation resources

20 MW

Example: 20 MW / 5 MWhlimited energy resource

Green – prior requirement

Yellow – regulation energy management

Approved by ISO Board February 2010. Implementation Spring 2012


Regulation energy management maintains resources state of charge to meet continuous energy requirement

  • Utilize real time energy market for energy offset

  • Regulation and energy settlement similar to conventional generation

  • Regulation dispatch and energy offset keep state of charge near midpoint

March 2010 ancillary services modifications to support non generation resources
March 2010 ancillary services modifications to support non-generation resources

  • Removed resource type restrictions and reduce minimum rated capacity to 500 kW from 1MW

  • Reduced minimum continuous energy requirement from 2 hours to:

    • Day-Ahead Regulation Up/Down: 60 minutes

    • Real-Time Regulation Up/Down: 30 minutes

    • Spin and Non-Spin: 30 minutes

  • Minimum continuous energy measured from the period that the resource reaches the awarded energy output

    • Measurement starts once resource reaches awarded energy, not end of 10 minute ramp requirement

Approved by FERC September 2010
