Uncommitted Energy Efficiency

View Workshop Documents

The California Energy Commission's (Energy Commission) Integrated Energy Policy Report (IEPR) Committee will hold a workshop to obtain comments on the staff's revised 10-year forecasts of annual natural gas, electricity, and peak demand. Commissioner Jeffrey D. Byron is the Presiding Member and Vice Chair James D. Boyd is the Associate Member of the IEPR Committee. Other Commissioners from the Energy Commission or the California Public Utilities Commission (CPUC) may also attend and participate in this workshop. The workshop will be held:

10 a.m.
1516 Ninth Street
First Floor, Hearing Room A
Sacramento, California
(Wheelchair Accessible)

Web Conferencing - Presentations and audio from the meeting will be broadcast via our WebEx web conferencing system. For details on how to participate via WebEx, please see the "Participation through WebEx" section at the end of this notice.


At this workshop, Energy Commission staff will present their revised 10-year forecasts of electricity demand and consumption, and, where appropriate, natural gas end-use consumption, including discussion of the methods, data, and assumptions used to develop those forecasts. Load serving entities (LSEs) and other parties who wish to propose alternative demand forecasts or have questions on the assumptions and methods of the staff demand forecasts should use this workshop as their opportunity to contribute to the record of the proceeding. Staff will also discuss the amount of conservation savings incorporated within the forecast and the methodology behind these estimates.

In addition, staff will describe the methodology being used in the "uncommitted" forecast to be completed later this year in support of the CPUC's 2010 Long-Term Procurement Process, and report on progress made to this point.


Energy Commission staff has developed revised forecasts of electricity and end-user natural gas consumption and peak electricity demand for each major utility planning area within California for the 10-year period, 2010-2020. These forecasts will be published in a staff report prior to the workshop []. Staff conducted a workshop on June 26, 2009 to receive public comments on the staff draft forecast. Staff has revised the forecast to address many of the comments received, as well as direction from the IEPR Committee. The demand forecasts are prepared using Energy Commission forecast methods; they are not dependent on any LSE forecast.

Following the workshop, the Committee will provide direction to staff concerning any remaining revisions to the demand forecast. The final forecasts will be used in a number of applications, including the 2009 IEPR, the CPUC's 2010 procurement process, and the Energy Commission's electricity supply-demand assessments. The final forecasts will also be an input to the California Independent System Operator's controlled grid studies, other transmission planning studies, and the California Gas Report.

The 2007 IEPR identified the need to conduct a public process to determine an effective method to better measure the energy efficiency savings assumptions in the Energy Commission staff's demand forecast. To address this issue, Energy Commission staff developed a conceptual project plan that includes valuable input from other entities such as the CPUC, Itron, and California utilities. This plan was presented in the 2008 IEPR Update and discussed during an August 12, 2008 IEPR Committee workshop, and includes an uncommitted energy efficiency projection capability to support the CPUC Long-Term Procurement Process. Uncommitted efficiency savings are those reasonably expected to occur but not yet implemented or funded. Energy Commission staff, with consultant support, will develop a forecast later this year which estimates the impacts of uncommitted savings on electricity consumption and demand through 2020, using the staff demand forecasts as the reference point.
