R.19-09-009 Order Instituting Rulemaking Regarding Microgrids Pursuant to Senate Bill 1339

Energy Division will host a public workshop as part of Track 5 Value of Resiliency of the Microgrids proceeding (R.19-09-009) on Tuesday, May 10, 2022 from 2:00 PM-4:00 PM.

TOPIC: Economic and Equity Impacts of Large Disruptions 

Rulemaking 19-09-009 facilitates the commercialization and deployment of microgrids while prioritizing system, public, and worker safety and avoiding shifting costs between ratepayers. On September 12, 2019, the Commission initiated this Rulemaking to design a framework surrounding the commercialization of microgrids associated with Senate Bill (SB) 1339 (Stern, 2018), as well as to account for the Commission’s commitment toward utilizing additional technologies, tools and activities that may be useful for achieving overall resiliency goals.

As part of the development of Track 5 issues focusing on the value of resiliency, the CPUC is holding workshops to explore topics previously identified in the Resiliency and Microgrids Working Group meetings as those that need more in-depth discussion and consideration. The topics may be subject to change and reprioritized as the discussions evolve over the course of the series of workshops.

This is the first workshop in Track 5 of the Microgrids proceeding R.19-09-009 focusing on “Economic & Equity Impacts of Large Disruptions”. We will have presentations on two tools developed by Lawrence Berkeley National Labs (LBNL): The Interruption Cost Estimate (ICE) calculator, and the Power Outage Economic Tool (POET). While we had a presentation on these tools during the Resiliency and Microgrids Working Group meeting series on value of resiliency, it was the first time many stakeholders had heard of either of the tools, and only briefly touched on the POET. 

LBNL is in the process of conducting an update of the ICE calculator, used by many utilities around the country to estimate value of lost load or value of service in GRC cases and other proceedings where value of service and/or customer outage impact is sought.  The ICE calculator is intended to be a tool to estimate short-duration economic outage impacts on customers.  The POET tool is currently being piloted to estimate long-duration economic outage impacts on customers.  The presentations will discuss the components behind the tools including the customer surveys reflecting willingness-to-pay, what is new in the updated version of the ICE 2.0 tool, what information gaps the POET tool aims to fill, and how it differs from the ICE calculator.  We are looking to use this workshop to deepen stakeholder’s education, knowledge, and inquiry about these tools.
