MAGALIA, CA (MPG) — Pacific Gas and Electric Company (PG&E) has begun construction on a microgrid designed to provide electricity to certain customers and shared community resources using temporary generation during future Public Safety Power Shutoff (PSPS) events.

The temporary microgrid generation site in Magalia was identified and selected through an extensive process involving the analysis of prior and expected future PSPS events, along with overall feasibility and other utility work in the region that could reduce PSPS impacts. The plan for a Magalia temporary microgrid energization zone includes approximately 40 PG&E customers served by underground power lines to be safely energized during a PSPS event.

“The Magalia microgrid is one of several sites being developed across PG&E’s service area in 2020-2021 as a part of the company’s comprehensive actions to reduce wildfire risks across our system and minimize the impact of public safety outages on our customers and communities,” said Debbie Powell, vice president, Asset & Risk Management, Community Wildfire Safety Program, PG&E. “Our specific objective with the development of temporary microgrids is to provide electricity to resources such as medical facilities and pharmacies, police and fire stations, gas stations, banks, markets and other shared community services when weather conditions make it unsafe to operate the grid.”

PG&E currently has six temporary microgrid generation sites ready to use during PSPS events throughout its service area. Including Magalia, five additional sites are currently in development. See below for the full list of locations.

The under-construction temporary microgrid generation site in Magalia is located at 14049 Lakeridge Circle. Once completed, when conditions allow, PG&E will be able to rapidly connect mobile generators to the site, allowing the fire station, sheriff’s substation, post office, water district facility, a gas station, markets, church, drug store and restaurants among other community services to remain energized during future PSPS events impacting the area. The Magalia temporary microgrid energization zone includes PG&E customers in the Skyway and Lakeridge Circle loop and north on Skyway up to approximately Drexel Drive.

Weather conditions and other operational considerations prevent PG&E from guaranteeing electricity to all customers potentially served by this temporary microgrid during all PSPS conditions or scenarios.

PG&E anticipates completing construction on this microgrid generation site in December 2020, depending on weather conditions. Once the site is operational, PG&E will be able to island customers within the temporary microgrid energization zone during PSPS events. Islanding refers to the ability of a microgrid to disconnect from the larger power grid: when the power is turned off during a broader grid outage; the area supported by the microgrid may remain energized and operate autonomously.

While performing this critical safety work during the COVID-19 pandemic, crews will maintain proper social distancing recommendations and wear protective equipment when necessary to help safeguard the health and safety of themselves and the general public.

PG&E customers in the vicinity of the construction site will receive an automated, courtesy phone call from PG&E notifying them of the work taking place.

Customers who are within the temporary microgrid energization zone will receive a separate communication from PG&E, notifying them of their inclusion in the microgrid and informing them of how it will operate during a PSPS event.

In addition to deploying temporary microgrids, which are primarily designed to keep shared community services energized, PG&E is working on a number of improvements to make PSPS events less impactful for customers, including:

Sectionalizing and Reconfiguration: Installing more than 600 additional sectionalizing devices this year capable of re-directing power and limiting the size of outages. PG&E also analyzed its grid configuration to ensure as few customers as possible are impacted by future PSPS events.

Substation Microgrids: PG&E’s substation microgrid solution is intended to reduce the impact of transmission-level PSPS events, which is when PG&E must turn off power to higher-voltage transmission lines for safety. Transmission-level shutoffs generally impact a larger number of customers—some in areas that are not directly experiencing the severe weather conditions. Sixty existing substations are now prepared to use mobile generators when needed to help keep power on for safe-to-energize customers nearby. PG&E identified these substations as having a higher likelihood of experiencing future PSPS events based on historical weather data and past PSPS events.

Community Resource Centers: Providing customers impacted by PSPS events with a climate-controlled environment and a space to charge electronic devices and receive refreshments.
