The California Energy Commission's (Energy Commission) Integrated Energy Policy Report (IEPR) Committee will hold a workshop to obtain comments on the staff's proposed 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:

FRIDAY, JUNE 26, 2009

1516 Ninth Street
First Floor, Hearing Room A

The purpose of the workshop is to understand the range of perspectives concerning 10-year energy demand forecasts. At this workshop, the Committee expects the staff and load serving entities (LSEs) to present their 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. Parties who wish to propose alternative demand forecasts or to question the assumptions and methods of entities contributing demand forecasts should use this workshop as their opportunity to contribute to the record of the proceeding. In addition, staff will discuss the amount of conservation savings incorporated within the forecast and the methodology behind these estimates.


Energy Commission staff has developed 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. The staff's demand forecasts are prepared using Energy Commission forecast methods; they are not dependent on the LSE forecasts.

To provide the Energy Commission and the public with the opportunity to consider alternative perspectives on demand trends, the Energy Commission requested electricity demand forecasts and related information from all LSEs with peak load greater than 200 megawatts. These forecasts were submitted to the Energy Commission in February 2009. At the workshop, staff will present a comparison between its forecasts and the forecasts submitted by those LSEs.

Following the hearing, the Committee will provide direction to staff or LSEs concerning revisions to demand forecasts. 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.
