PG&E filed a decade of burying wires the day Sacramento voted to cut the profit on burying wires
PG&E filed a 10-year plan to bury 5,000 miles of wire and claims $117 billion of benefits, more than 10 times an investment figure it never gives. Sacramento signed a law the day before that targets the profit on exactly this work, and three underground vaults exploded in San Francisco the day it was filed.

The timing is almost comic. On 1 October, PG&E filed its 10-Year Electrical Undergrounding Plan with the state: about 5,000 miles of distribution line buried from 2028 to 2037 across more than 30 counties, promising a 98% cut in ignition risk and 90% fewer outages on the lines it moves 1. That same afternoon, three of its already-underground vaults exploded in San Francisco's Financial District, sending flames into the air, closing six blocks and triggering a five-hour shelter-in-place 5.
The unnumbered bill
The release claims $117 billion in long-term benefits, "more than 10 times the value of the proposed investment" 1. It never states the investment. Run the arithmetic on what the record does carry: PG&E's quarterly capital spending has climbed from $2.6 billion in Q3 2024 to about $3 billion a quarter, and the company still plans roughly $11.4 billion of California capex in 2027 even after deferring $2 billion of it to cut borrowing costs 37. A decade of undergrounding at that run rate is a per-mile question the press release answers with adjectives. Even at $3 million a mile, 5,000 miles approaches $15 billion; the plan's 10x framing implies a denominator far larger, and no source gives it.

Sacramento just cut the return
The day before the filing, Governor Newsom signed SB 905 in the session's final hours, directing the CPUC to consider lowering utility profit on lower-risk investments, "such as undergrounding power lines," where utilities often earn 9% or 10% on new transmission projects 2. PG&E opposed the bill, warning it would discourage investment 2. Its Sep 2 strategic review, which re-evaluates the 2028-2030 capital and rate-base outlooks, already reads like a company bracing for exactly that 3.
Who is watching the ledger
The math for shareholders is simple: PG&E needs high-single-digit returns on a decade of buried wire to earn its way back to investment grade, and the legislature just named that asset class for a haircut. The stock closed at $12.17, down 24% year to date, against a $19.22 analyst average target after UBS's 23 September cut to $14 6. Director John Larsen bought 7,500 shares at $12.20 on 30 September, two days before the filing, a $92,000 vote of confidence 4. Ratepayers get a different bill and no denominator at all. Energy Safety reviews the plan next; the CPUC rules on the costs; Q3 earnings land 22 October 3.

No source states what the 5,000-mile plan will cost; that number, and whether $117 billion survives the SB 905 regime, is what October 22 and the regulatory record will have to show.
