  • April 23, 2013:  Workshop to implement CSI-Thermal incentives for new technologies, and add solar pools

    The CSI-Thermal program administrators (PAs) are hosting a workshop to implement Decision (D.)13-02-018 which authorizes new technologies to be included in the program and introduces the performance based incentives (PBI) payment scheme.  The PAs will present a straw man proposal and invite comment and discussion.  The workshop will also address Assembly Bill (AB) 2249, which authorizes inclusion of solar heating for swimming pools (except single family residences).  The workshop will start at 10:00 a.m. and will be held at the Golden Gate Room at the CPUC at 505 Van Ness Avenue in San Francisco.  To call into the workshop, dial 1-866-812-4996, and use participant code 2830995#
  • October 22, 2012:  Workshop on Net Energy Metering (NEM) Cost-Benefit Study

    Energy Division is overseeing an update to the 2010 Net Energy Metering (NEM) Cost Effectiveness Evaluation. This study fulfills the requirements of Assembly Bill 2514 (Bradford, 2012) and Commission Decision 12-05-036 to study the costs and benefits of NEM by October 1, 2013. The purpose of this workshop is to discuss the proposed methodology and revised scope of work for the updated NEM study.  For more information, please click here
  • June 25, 2012:  Net Energy Metering (NEM) Workshop to Discuss Methods for Calculating Non-Coincident Aggregate Customer Peak Demand

    Net metering allows customers who install small (1MW or less) distributed generation facilities to receive full-retail credit for power generated by their onsite system and fed back to the utility.  Pursuant to Public Utilities Code 2827, the net metering program cap is defined as 5 percent of a utility's aggregate customer peak demand.  In Decision 12-05-036, the Commission clarified that aggregate customer peak demand means sum of individual customer's non-coincident peak demand; the purpose of this workshop is to discuss the methods for estimating individual non-coincident peak demand.
  • February 15, 2012:  Workshop on Cost Reporting in CSI for Third-Party Owners

    Over time, the proportion of CSI systems owned by third parties i.e. by parties other than the host customers--has grown substantially.  Because these systems involve no sale to the host customer, determining the value to report for "Project Cost" presents challenges to third party owners.  This workshop was convened by the CSI Program Administrators to examine ways in which third party owners are reporting "Project Cost", to review the policy goals behind this reporting effort, and to discuss possible approaches.
  • December 8, 2011  1:00 p.m.:  Workshop on Expansion of Virtual Net Energy Metering to General Market Customers

    Under the California Solar Initiative (CSI) Multi-family Affordable Solar Housing (MASH) Program, the CPUC authorized utility tariffs for Virtual Net Energy Metering (VNM).  VNM enabled allocation of bill credits from a solar PV system across multiple benefitting account meters in an eligible affordable housing complex.  In recent modifications to the CSI program in D.11-07-031, the CPUC directed PG&E, SCE and SDG&E to file advice letters to expand VNM eligibility to all "residential, commercial and industrial multi-tenant and multi-meter properties, with the limitation that sharing of bill credits can only occur for accounts served by a single [service delivery point]."  (Ordering Paragraph 2.)  This workshop discusses the advice letters that were filed by the utilities (PG&E 3902-E; SCE 2625-E; SDG&E 2286-E) as well as protested points and unresolved issues.
  • August 3, 2011  10:00 a.m.:  Workshop on CSI-Thermal Market Facilitation Component

    In June 2011, the CSI-Thermal Program Administrators selected Fraser Communications to conduct a statewide marketing campaign aimed at increasing public awareness of the benefits solar water heating.  At the same time, the PAs are finalizing their plans to conduct local market facilitation activities in the own service territories.  At this workshop, Fraser and the PAs will present their approach to the statewide campaign and the local market facilitation activities.  The workshop will provide Energy Division and interested members of the public the opportunity to hear the plans, ask questions, and offer feedback.  In particular, Energy Division wishes to identify any potential objections to the proposed approach early in order to avoid protests when the PAs formally file their plans.
  • February 23, 2011  9:30 a.m.:  Workshop on opening the CSI-Thermal Program to new technologies

    This workshop will provide parties the opportunity to provide input on the challenges and opportunities involved in opening the CSI-Thermal Program to new technologies and end-use applications.  Currently, the CSI-Thermal program only offers rebates to technologies producing hot water that is directly consumed as an end use.  At the workshop, will discuss opening the program to other technologies and end uses, including space heating, solar cooling  and process heat .  The workshop will focus on the challenges that will need to be overcome to include these technologies in the program, primarily the development of system design standards and calculation of incentive payments.  Part of the day will be dedicated to the possibility of creating a "Performance-based Incentive" option by which systems would be paid based on actual energy savings.
  • November 17, 2010 10 a.m.:  Workshop on California Solar Initiative (CSI) Staff Proposal No. 2

    This workshop will provide parties the opportunity to discuss a subset of recommendations included in the CSI Staff Proposal, issued via ruling on July 26, 2010, containing suggested modifications to the California Solar Initiative.  The purpose of this workshop is to help ensure that parties' are well informed on issues within the CSI Staff Proposal prior to filing written comments as directed by the November 9, 2010 Scoping Memo.  Each recommendation will begin with a brief overview of the issue, followed by the opportunity for questions and/or comments by the audience.  To facilitate a robust discussion, we strongly encourage parties to review the sections containing the recommendations to be discussed at the workshop prior to the event.  Please review the workshop agenda to see which topics will be discussed in the workshop.
  • October 25, 2010 10 a.m.:  Workshop on California Solar Initiative (CSI) Staff Proposal

    This workshop will provide parties the opportunity to discuss a subset of recommendations included in the CSI Staff Proposal, issued via ruling on July 26, 2010, containing suggested modifications to the California Solar Initiative.  Each recommendation will begin with a brief overview of the issue, followed by the opportunity for questions and/or comments by the audience.  To facilitate a robust discussion, we strongly encourage parties to review the sections containing the recommendations to be discussed at the workshop prior to the event.  The list of specific recommendations to be discussed at the workshop is available here
  • August 4, 2010 9 a.m.:  Workshop on California Solar Initiative (CSI) Cost Effective Evaluation

    This workshop will provide parties the opportunity to understand and review the methodology and results of the CSI Cost-Effectiveness Evaluation conducted by Energy+ Environmental Economics (E3) in the morning with the afternoon dedicated to walking participants through the Single Installation Tool developed by E3.
  • July 9, 2010 9 a.m.:  Workshop on Net Surplus Compensation Pursuant to Assembly Bill 920
    • Agenda
    • Presentations
    • Webcast

      This workshop provided parties with the opportunity to explain their proposals on how a rate should be set to compensate net energy metering customers for excess generation produced over a 12-month pursuant to Assembly Bill 920.  Parties presented their methodology for calculating the Net Surplus Compensation Rate and applied that methodology to a hypothetical customer as described in the June 1 Scoping Memo.  In addition, parties provided answers to policy questions posed in that memo.  Each presentation was followed by a question and answer period in which Energy Division, ALJ Duda and other parties had the opportunity to examine the proposals.
  • March 30, 2010, 9 a.m.:  Workshop on California Solar Initiative (CSI) Thermal - Multifamily/Commercial SWH Program Handbook

    This workshop will focus exclusively on the portion of the CSI-Thermal Program that will offer incentives to multi-family and commercial buildings installing Solar Water Heating (SWH).  The single-family portion of the handbook was addressed in a workshop on February 23, 2010.  The low-income and non-SWH portions of the program will be covered in later workshops.  Each section of the agenda will begin with a presentation on the relevant section of the Program Handbook, highlighting important areas of uncertainty that need to be resolved, followed by an opportunity for questions from the audience.  To help facilitate a robust and targeted discussion, Energy Division has distributed a draft Handbook that proposes solutions to some of the relevant implementation issues.  This draft Handbook should be considered a straw proposal intended to solicit feedback, rather than a final document.  In addition to soliciting input on the multi-family/commercial section of the Handbook, we will also address at this workshop the calculator that will be used for calculating incentives amounts.  Questions about the workshop should be directed to Damon Franz at (415) 703-2165 or

    This workshop will be held at the Milton Marks Conference Center, San Diego Rooms A/B/C, 455 Golden Gate Avenue, San Francisco 94102.
