Demand Side Management

ACTIVITIES | DOCUMENTS | CORRESPONDENCE   The purpose of the State-Provincial Steering Committee's DSM Work Group is to ensure that WECC's reference case for transmission planning studies accurately reflects existing DSM programs and policies and to develop high DSM scenarios for a more comprehensive evaluation of potential demand-side actions (energy efficiency, demand response, distributed generation) as part of transmission expansion planning studies. The work group will work closely with WECC's Transmission Expansion Planning Policy Committee in executing SPSC DSM study requests, and will maintain ongoing communications with the full SPSC. If you would like to become involved in the activities of this work group, please send an email to sharon@westgov.org asking to be added to the DSM Work Group listserve. If you have questions or suggestions regarding the activities of the DSM Work Group, please contact Lisa Schwartz (lschwartz@raponline.org; 541-990-9526) or Steve Ellenbecker (sellenbecker@westgov.org; 303-573-8910).

 

2011 SPSC High DSM Study Case Supporting Documents
The DSM Work Group has completed the development of methodologies and technical data in support of its 2011 High DSM/DG study requests. The following set of excel spreadsheets identify the Energy Efficiency (EE), Demand Response (DR) and Distributed Generation (DG) resource levels in the study case, which have been forwarded to WECC staff.
	EE Savings and Load Forecasts		High DG Capacity Numbers		SPSC High DSM Case DR resource levels
In addition, the two PDF documents explain: the DR modeling assumptions and dispatch methodology and the methodology used to develop the DG numbers

December 16, 2011 WECC webinar on Energy Efficiency (EE) and Demand Response (DR) Assumptions for the 2022 WECC Common Case
WECC is holding a series of five webinars highlighting major inputs in the WECC 2022 Common Case.   The December 16, 2011 webinar focused on the Energy Efficiency and Demand Response Assumptions.    These inputs were presented by Galen Barbose and Andy Satchwell of LBNL, reflecting their work for the SPSC DSM Work Group.  Below, please find their presentations in the webinar, along with the presentation of Heidi Pacini, WECC Staff Engineer, introducing summarizing WECC’s 2022 Common Case assumtions.

Demand Response (DR) potential in the 2011 SPSC High DSM Case
On December 12, 2011, initial results of the Demand Response (DR) potential in the 2011 SPSC HIgh DSM Case were circulated to the DSM Work Group for review and feedback. Feedback directly to Andy Satchwell at LBNL (asatchwell@lbl.gov) was requested by Friday, December 16. LBNL subcontracted with The Brattle Group to update DR potential estimates from the FERC 2009 National Assessment of Demand Response Potential. The updated DR potential estimates reflect major developments in DR program design, enrollment, and participation. High level results of the updated model are:
1) For the Enhanced-BAU scenario, the previous WECC-wide DR impact was 6% (2019); updated model is 7% (2022).
2) For the Achievable Participation scenario, the previous WECC-wide DR impact was 13% (2019); updated model is 14% (2022).
The updates are described in detail in a PDF provided below, along with a copy of the Dec. 12 distribution memo briefly explaining the analysis and results. Also included below, is the state-level DR potential in the High DSM case for review by Work Group participants, consisting of several worksheets, organized under an "Assumptions" Tab and "Results" Tab. The Dec .12 distribution memo accompanying these documents includes additional guidance for reviewing the documents.

SPSC 2011 High DSM Scenario “Energy Efficiency Savings Projections”
On November 28, 2011, the following EE assumptions and calculations in the 2011 HighDSM/DG case were distributed to the DSM Work Group for review and feedback no later than Dec. 16. EE results are shown for each state and province, with the exception of the Pacific Northwest, where results are consolidated in a single document since they are keyed off the Council's 6th Plan.

October 13, 2011 DSM Work Group follow-up

In the course of the October 10th DSM Workgroup conference call, several follow-up questions were posed for Work Group participants, which are summarized in the attached memo.

 

2011 DSM Study Activities

Last year, the DSM Work Group played a key role in determining state-adjusted load forecasts that fully accounted for expected energy efficiency from existing programs and policies – the SPSC Reference Case – and developing the High DSM scenario that reflected acquisition of all cost-effective energy efficiency.  In 2011, the SPSC Reference Case will serve as WECC’s “Common Case” for transmission planning, so our work takes on greater importance. We also will be providing guidance on new issues, including: • Energy efficiency and demand response assumptions for WECC’s first 20-year studies • Incorporating distributed generation in the high DSM cases (10- and 20-year) • A geographically-targeted high DSM case                The Work Group will initially provide input on two first priority 10-year analyses: 1. The updated SPSC Reference Case/WECC Common Case, in the June-August time frame 2. The High DSM / Distributed Generation case in the September-December time frame                      This will be followed by an analogous set of 20-year cases and the development of a geographically targeted High DSM/distributed generation case. Lawrence Berkeley National Laboratory will again lead the technical analysis, and this year Lisa Schwartz from the Regulatory Assistance Project will provide direct support to the Work Group.

2011 Energy Efficiency and Demand Response
Adjustments for TEPPC 2022 Common Case

The DSM Work Group has completed our technical analysis of energy efficiency (EE) and demand response (DR) adjustments to the WECC 2022 Common Case, and has submitted these proposed adjustments to TEPPC.  The following information on  the analysis  includes links to the relevant documents. Energy Efficiency Adjustments SPSC’s proposed adjustments to the Balancing Authority (BA) load forecasts  account for the expected impact of current EE policies and program plans.  The file which is available via this link consists of two tables showing the % adjustments to the monthly energy and monthly peak demand (respectively) for each BA. An  18-page document has been prepared describing the methodology used to develop the EE adjustments, including an explanation of the underlying rationale supporting the adjustments for each BA.  This document includes several charts showing the magnitude of adjustments and summarizing results.  The document is available here. An analysis file containing the data, assumptions, and calculations used to develop the EE adjustments for each BA is available here. Demand Response Adjustments A summary of the recommended adjustments to the BA non-firm load forecasts (dispatchable demand response)  in the WECC 2022 Common Case is available here.   A spreadsheet containing the data supporting the DR adjustments is available here. The transmission planning studies conducted by WECC utilize a production cost model (PROMOD) to model the dispatch of generation and  DR resources in the Western Interconnection.  The DSM WG has proposed several DR modeling assumptions for use in the WECC 2022 Common Case.  A discussion of these proposals is available here.

 

SPSC /DSM Working Group Approval of “SPSC - Adjusted State Load Forecasts” The following Table is meant to facilitate tracking the review and approval process for “SPSC-Adjusted State Load Forecasts" identified in Commissioner Dian Grueneich’s memo of July 9. These forecasts are intended to be used in developing the TEPPC 2020 reference case, and will serve as the base in developing other specific DSM scenario requests. Below, under Documents (dated July 22) please find an explanation of the analytical steps taken to adjust State Load forecasts to reflect anticipated Federal Lighting and Appliance Standards. As identified in Commissioner Grueneich's email, we must work within the TEPPC schedule to complete our review. The deadline for SPSC member approval is August 4. Separate communications are being sent to individual SPSC and DSM Work Group members to facilitate the review and approval process.
