California Energy Commission (CEC) staff, in consultation with Energy and Environmental Economics, Inc. (E3), will present and summarize the Solar + Storage Modeling Tool developed by E3 under Electric Program Investment Charge (EPIC) agreement EPC-17-004, “Enhanced Modeling Tools to Maximize Solar + Storage Benefits”. The Solar + Storage Modeling Tool evaluates the benefit of solar, storage, and other distributed energy resources (DERs), and estimates the value proposition of the integrated systems based on their expected optimal operations, location on the grid, market prices, and other characteristics. This is the final of three workshops on the Solar + Storage Modeling Tool.


The workshop will summarize the Solar + Storage Modeling Tool, discuss the changes and improvements to the tool since the initial public release, review case studies in which the tool was used to assesses the cost effectiveness of photovoltaic (PV), storage, and other DER technologies, and discuss recommendations and next steps.

Staff is seeking input on:

  1. What additional features or capabilities would you like to see added that would be most beneficial to you?
  2. Have you used or do you plan on using this tool to assess the cost effectiveness of PV, storage, and other DER technologies? If so, what is the use case?
  3. What are your recommendations on how this tool can be improved?

The primary audience for this workshop includes representatives that are focused on DER project development evaluation, including utilities, project developers, DER vendors, and policy makers.
