PG&E's Landmark RFI to Underground Ten Thousand Miles of Lines


Pacific Gas & Electric

Fortnightly Magazine - October 25 2021

On the twenty-second of July, Pacific Gas & Electric announced its commitment to underground ten thousand miles of its power lines to help reduce wildfire risk and address climate change. Then, on the twelfth of August, the company issued a Request for Information, an RFI, seeking approaches to what the company termed "this feat." 

By the end of September, PG&E met with firms that responded to the RFI, each of which presented their approaches to accomplish this unprecedented project, and necessarily implement a range of innovations to succeed. We do not yet know the outcome of these monumental steps in strategic undergrounding, but given the importance for the entire electric utility industry, the PUF team provides herein the key excerpts of the RFI.

RFI's Purpose

On July 22, 2021, the company announced its commitment to underground 10,000 miles of electric lines beginning in High Fire Threat Districts across our service area to help reduce the risk of major wildfires and address the challenge of climate change. The scale of our plan is unprecedented, and the strength of our commitment is unparalleled. This represents the largest effort in the U.S. to underground power lines as a wildfire risk reduction measure.

We know that we cannot do this alone – we need help. We want partners in thought and action, with courage and conviction, that will challenge us, share our commitment, and co-create what will become the country's most modern and expansive underground electric system. As such, PG&E is inviting your response to this Request for Information (RFI) to seek creative approach(es) to achieve this feat; however, this is more than just a Request for Information – it is an invitation for industry-leading Imagination, Ideas and Innovation that will provide safe and reliable energy to California for generations to come.

Participants are requested to submit four (4) elements within their response: (1) general company overview, (2) recommended approach(es), (3) response to supplemental questions, and (4) relevant project examples. Responses are due no later than 4PM PT on Thursday, September 2nd, 2021. Information submitted in this RFI will be used to identify participants with whom PG&E is interested in furthering discussions around the proposed approaches and innovative ideas.

Thank you in advance for your interest in partnering to help us achieve this audacious and ambitious goal on behalf of our more than 5 million customers.
