Greenhouse Gas Workshop -- April 21-22, 2008

Workshop Notice – R.06-04-009: Order Instituting Rulemaking to Implement the Commission’s Procurement Incentive Framework and to Examine the Integration of Greenhouse Gas Emissions Standards into Procurement Policies.

  • When?
    • April 21-22, 2008 (begins at 10 a.m. on April 21; 9 a.m. on April 22)
  • Where?
    • California Public Utilities Commission Auditorium, 505 Van Ness Avenue, San Francisco
  • What?
    • The California Public Utilities Commission (CPUC) and the California Energy Commission (Energy Commission or CEC) will conduct a joint workshop in order to discuss greenhouse gas (GHG) emission allowance allocation methods in the electricity sector and review Stage 2 modeling results. This workshop is part of the ongoing joint proceeding to provide recommendations to the Air Resources Board regarding implementation of Assembly Bill 32 (Nuñez), Chapter 488, Statutes of 2006.

The workshop will be a forum for stakeholders to discuss a staff paper analyzing GHG emission allowance allocation methods that will be issued shortly, as well as results of economic modeling of the options presented in the staff paper.

The CPUC has engaged Energy and Environmental Economics, Inc. (E3) to utilize production simulation and other modeling tools to assess the costs of alternative policy scenarios aimed at achieving GHG reductions within the electricity sector.

E3 is conducting its work in two stages. Stage 1 focused on model architecture and broad analysis of the overall level of GHG reduction achievable by the sector within the 2020 timeframe and related costs to ratepayers. In January, 2008 parties filed opening and reply comments on the preliminary Stage 1 results. In response to those comments and to reflect the policy decisions jointly adopted by the CPUC and CEC in Decision 08-03-018, E3 has made further modifications to its model in Stage 2 and also has expanded its functionality to model the impacts on rates, power prices and total program costs of several different emission allowance allocation methods identified in the forthcoming staff paper.

At this workshop, E3 will explain modifications made in response to Stage 1 comments, educate parties on the additional functionality of the model, and present preliminary results for Stage 2.

A quorum of Commissioners from the CPUC may attend the workshop.

The workshop Agenda will be made available prior to the event.

Presentations from this workshop are available.

This workshop will be available via video webcast. Those participating via the webcast may email their feedback or questions to Adam Langton at for consideration during the discussion section of the workshop.
