What happened
The number arrived the way big regulatory numbers usually do: buried in testimony, then impossible to ignore. PG&E submitted testimony to the California Public Utilities Commission (CPUC) on Tuesday setting out $22.5 billion as the cost of a government takeover of its San Francisco grid, and announced the figure publicly on Wednesday in its own release and in comments reported by Reuters. The testimony ran to 1,164 pages, according to SF Standard reporting — a formal opening position in a valuation proceeding the city itself started in 2021, not a settlement offer and not a price set by any regulator.
The scale is worth pausing on. The $22.5 billion is higher than the “more than $20 billion” that Poppe previewed last week at a Climate One event at the Commonwealth Club, and it exceeds San Francisco’s entire annual budget of roughly $17 billion. On PG&E’s arithmetic, the city would be contemplating a transaction worth about a third more than everything it spends in a year. That comparison does not settle whether the purchase would be wise — assets are bought once and financed over decades, while budgets recur annually — but it frames the political problem: this is one of the largest municipal acquisition proposals in modern American history, at least on the seller’s math.
Poppe’s framing was direct. “A government takeover of our grid is not the right solution for our San Francisco customers,” she said, adding that the filing showed a takeover did not make financial sense for customers. PG&E’s release described the $22.5 billion as the CPUC-required costs of a takeover, including $8.6 billion in business severance damages and physical separation costs that the city’s valuation does not yet address. The CPUC did not immediately respond to a request for comment, Reuters reported. And no response from the city to the $22.5 billion filing itself has been reported yet — an important caveat, because the sharpest city quote in circulation, City Attorney David Chiu’s “absurdly inflated,” was aimed at Poppe’s roughly $20 billion preview, not at Tuesday’s filing.
How the two numbers are built
The headline gap — $22.5 billion against $3.4 billion, a ratio of more than six to one — invites a simple reading: one side is lowballing, the other is inflating. The filings support a more interesting reading. The two numbers were built to answer different questions.
Start with the city’s $3.4 billion, filed in April 2026. That figure estimated the fair-market value of the grid’s assets — the poles, wires, substations, underground network and associated property inside San Francisco, valued as property. It did not attempt to price what it would cost to cut the city’s system out of PG&E’s wider network, or what PG&E would lose by being cut.
PG&E’s $22.5 billion answers a broader question in two parts. The first part is the assets, which PG&E valued at $13.9 billion — already about four times the city’s figure for ostensibly the same property. PG&E argued the city undervalued its underground network, a significant point in a dense city where so much of the distribution system runs below the streets, and that the city’s number excluded more than 2,000 real-estate interests, including easements and licences — the legal rights that let equipment sit on, under and across other people’s land. An easement sounds like paperwork until you try to operate a grid without one.
The second part is the $8.6 billion the city’s number does not contain at all: severance and separation. Separating San Francisco from PG&E’s system is not like unscrewing a lightbulb. PG&E said separation would require a replacement substation, likely in San Mateo County, a new service center, and reconfigured or new power lines, so customers outside the city who are served through infrastructure entangled with the city’s grid keep their service. On top of the physical works sit business-loss costs — the severance damages a utility claims when a chunk of its service territory, and the revenue it generates, is taken. Whether every dollar of that $8.6 billion is legitimate is precisely what the CPUC proceeding exists to test. But its existence is not an accounting trick: any honest takeover budget has to pay for the surgery, not just the organ.
There is one more structural fact, and it tilts the field before the argument even starts. California regulators have already ruled that the city must pay “the highest value” a hypothetical buyer might pay for the assets. Valuation law often works with standards like fair-market value between a willing buyer and a willing seller; a “highest value” standard is more demanding for the buyer, because it prices the assets at the top of the plausible range rather than the middle. PG&E did not write that rule, but its $13.9 billion asset figure is plainly built to live under it.
Some proportions help. San Francisco accounts for about 5 percent of PG&E’s electricity demand, according to Nancy Crowley, a spokesperson for the San Francisco Public Utilities Commission, as reported by Reuters, while PG&E’s entire electric system is worth about $60 billion. Five percent of $60 billion is $3 billion — remarkably close to the city’s $3.4 billion, which suggests the city’s figure is essentially a pro-rata slice of system value, adjusted upward. PG&E’s $13.9 billion, by contrast, prices San Francisco at nearly a quarter of the whole system’s value for a twentieth of its demand — a claim resting on the density and undergrounding of the city network being worth far more per customer than the system average. Both logics are internally coherent. They cannot both be the answer.
Why this matters
The deepest issue in this fight is not the price of a grid. It is who gets to define the price of leaving. Every municipalization campaign in America — and San Francisco’s is the largest and most advanced of them — runs into the same wall: the incumbent utility controls the engineering facts. Only PG&E knows, in operational detail, which feeders cross the county line, which substations serve both sides of it, and what must be rebuilt so the lights stay on outside the city while San Francisco goes its own way. A city can hire excellent consultants, as San Francisco has for years, but the separation estimate will always be built substantially on the seller’s map of the seller’s system. That asymmetry does not make PG&E’s $8.6 billion wrong. It makes it, structurally, an opening bid from the party with the most information and the strongest incentive to bid high — which is why the CPUC’s scrutiny, rather than either side’s press release, is where the real number will be decided.
The stakes run well beyond one city. Public-power advocates across the United States watch San Francisco the way chess players watch a champion’s game: if a wealthy, technically sophisticated city with its own public utilities commission cannot get through the valuation stage at a survivable price, the lesson for smaller cities is bleak. Conversely, if the CPUC endorses anything close to PG&E’s structure — highest hypothetical value, plus full severance, plus business-loss damages — it will have set the national template for what exit costs, and every investor-owned utility facing a municipalization threat will cite this proceeding. The wider energy context underlines how much rides on grid ownership: regulators elsewhere are managing grid emergencies across 13 states under federal orders, households are absorbing energy-price shocks that pushed Brent crude to $110, and corporate buyers are paying takeover-scale prices for energy technology, as in Schneider Electric’s move on PTC. Control of wires has become one of the defining economic contests of the decade, and San Francisco is its loudest courtroom.
There is also a quieter question of what the money would buy. PG&E says it has invested $3 billion in San Francisco’s grid over the past decade and plans nearly $2 billion more over the next five years. If the city pays tens of billions simply to acquire the existing system, that is money spent on ownership rather than on a single new wire, battery or undergrounded mile — capital that cannot simultaneously fund the reliability improvements the takeover is supposed to deliver. The city’s counter-logic is that ownership changes the flow of money for a century: no shareholder return, cheaper public financing, and rates set by a public board rather than negotiated with a regulated monopoly. Municipal utilities in the United States do, on average, charge less than investor-owned ones, though averages conceal wide variation. Both stories can be true at once: the takeover could be the right long-term structure and still be priced, at $22.5 billion, beyond what its own economics can carry. At some number, price is not a detail in this argument. Price is the argument.
Background: a takeover fight since 2021
San Francisco’s ambition to own its power system is older than PG&E’s current corporate form. The city already runs a substantial public power operation through the San Francisco Public Utilities Commission, generating hydroelectric power at Hetch Hetchy and supplying municipal buildings, the airport and other public customers — but most homes and businesses buy their electricity over PG&E’s distribution wires. The modern push began in earnest in 2021, when the city started the valuation proceeding that Tuesday’s filing now dominates, and it was championed under former Mayor London Breed. The current mayor, Daniel Lurie, has kept the reliability pressure on: according to reporting by The Inference, Lurie has asked the state to examine at least 40 large outages in the city since January.
The relationship has deteriorated in public, step by step. In September, the Board of Supervisors unanimously rejected PG&E’s appeal of the city’s environmental review, clearing a procedural hurdle for the city. Earlier this month the argument turned rhetorical: Poppe previewed a figure of more than $20 billion at the Climate One event, and City Attorney David Chiu called that figure “absurdly inflated.” Tuesday’s 1,164-page filing is, in part, PG&E’s answer: not a speech number, but testimony the company must now defend line by line before the CPUC. A chief executive’s round number at a climate forum is positioning. A formal valuation filing is a commitment.
Both sides
PG&E’s case
The company’s argument has three layers. First, the assets are worth more than the city admits: $13.9 billion, reflecting a dense, heavily undergrounded network and more than 2,000 real-estate interests — easements and licences — that the city’s appraisal left out. Second, separation is real engineering with real costs: a replacement substation likely in San Mateo County, a new service center, and reconfigured or new lines, all inside the $8.6 billion severance figure. Third, the record: $3 billion invested in the city’s grid over the past decade and nearly $2 billion more planned over the next five years, offered as evidence that the incumbent is addressing the system’s problems and that customers would pay an enormous premium to change the name on the substation fence. Poppe’s conclusion follows her premises: the takeover “is not the right solution,” and it does not make financial sense for the customers who would ultimately finance it.
The city’s case
The city proposed the takeover citing long-term cost savings, service reliability and affordability, and its officials dispute PG&E’s valuation. The reliability limb is not abstract: the mayor has pressed the state over at least 40 large outages in the city since January, and officials argue the current arrangement is failing residents on the most basic measure of a power system — whether it stays on. The affordability limb is structural: a public system borrows more cheaply, pays no dividend, and answers to elected supervisors rather than shareholders, so even an expensive acquisition could, in the city’s telling, pay for itself across the decades-long life of the assets. And the democratic limb is the oldest one: San Francisco built Hetch Hetchy a century ago, and city leaders frame the grid as the missing piece of a system the public already partly owns. What the city has not yet done, as of publication, is answer the $22.5 billion filing itself — neither publishing a rival all-in number that includes separation, nor conceding that severance belongs in the price at all. That silence is a position for now, but it cannot hold through the proceeding.
What happens next
The fight now moves from podiums to the proceeding. Regulators are weighing both the asset value and the separation cost, and the CPUC process will test PG&E’s 1,164 pages against the city’s appraisal under the “highest value” standard the commission has already set. Expect the contest to narrow to three battlegrounds: the underground network — how a buried system in a dense, seismically active city should be valued, and whether the city genuinely undervalued it; the easements — whether more than 2,000 real-estate interests carry the weight PG&E gives them; and severance — how much of the $8.6 billion is unavoidable engineering and how much is business-loss damages the commission may trim.
Three scenarios follow. In the first, the CPUC lands in the middle — an asset value well above $3.4 billion and severance well below $8.6 billion — and the city must decide whether a total in the low-to-mid teens of billions is a price its voters and budget can carry; at that point the argument becomes a bond measure and a political campaign. In the second, the commission endorses most of PG&E’s structure, the figure stays north of $20 billion, and the takeover stalls not on principle but on financing. In the third, the proceeding drags: valuation fights of this complexity rarely resolve quickly, PG&E’s planned investment proceeds under the incumbent anyway, and the question passes to the next mayor and the next board. For investors, the immediate exposure is narrower: San Francisco is about 5 percent of PG&E’s demand, and even a completed takeover would unfold over years.
What neither side can do is make the arithmetic disappear. San Francisco wants to buy a grid. PG&E has now stated, formally and at length, what it believes leaving would cost. Somewhere between $3.4 billion and $22.5 billion sits a number the CPUC will eventually defend in writing — and that number, more than any speech, will decide whether public power in San Francisco remains a century-old aspiration or becomes the largest municipal takeover in American utility history.
