What forecasts exist? • ISO-NE publishes annual forecasts within their Capacity, Energy, Loads and Transmission report (CELT) • This report now includes forecasts for all of New England and by state • The DPS has from time to time created a state-wide load forecast, with the last one created in 2002 • VELCO examines, on a regular basis, historic information for comparison against existing forecasts 9/13/05 Docket 7081 Workshop
What methodologies are used in these forecasts • ISO-NE uses information provided in FERC 715 submittals to create a state by state, and with historical load information, creates a load database which is then weather normalized to provide regional and state peak load forecasts • This forecast includes a set of predicted peak loads for the potential spectrum of weather • ISO-NE’s methodology is available at: • http://www.iso-ne.com/trans/celt/fsct_detail/index.html 9/13/05 Docket 7081 Workshop
