tl;dr PG&E has been a criminal enterprise operating illegally in San Francisco for well over a century.
Eminent Domain PG&E.

The great PG&E debacle: A timeline 1898-1997: A deep dive into the scandalous history of the power company, including the Raker Act and Hetch Hetchy dam deal:
The more I got into the story, the more I wondered: How could this have happened? How could a private company, with the city's assent, break federal law for so long? So at one point, about 30 years ago, I flew to Washington DC and spent two weeks in the National Archives, reading and copying documents that relate to the PG&E Raker Act scandal. I carried home two big boxes full of records, and over the next few months, put together a detailed chronology of the Raker Act, the construction of the city's water and power dam at Hetch Hetchy, and the politics of how this all happened. [...]
1912: With Spring Valley's private water rates continuing to rise, and service as poor as ever, city officials press Congress to give San Francisco a radical and unprecedented federal grant: the right to construct a municipal water dam inside a national park. John Muir is furious, and rages: "Dam Hetch Hetchy? As well dam for water tanks the people's cathedrals and churches; for no holier temple has ever been consecrated to the heart of man." He has founded the Sierra Club to fight the proposal, and congressional preservationists line up against it. [...]
1925: Transmission lines are strung all the way to the South Bay, when suddenly the city announces that it has run out of money and can't do any more construction. The city's power line ends just a few hundred yards from a PG&E substation in Newark -- which conveniently connects to a new high-voltage cable PG&E has just completed from Newark to San Francisco.
On July 1, 1925, since the city lacks not only a final transmission line but the local facilities to distribute its own power, city officials agree, as another temporary measure, to sell the Hetch Hetchy electricity at wholesale rates to PG&E, which then sells it to local customers at retail. The city makes a few million dollars off the deal; PG&E makes a fortune. The remaining copper wire is stashed in a warehouse and eventually sold for scrap. Every supervisor who votes to approve the contract is thrown out of office in the next election. [...]
1935: Ickes issues a detailed opinion concluding that the city's contract with PG&E is a clear violation of the Raker Act. He urges the city to revoke the contract and move with all dispatch to establish a municipal power system. Mayor Rossi acknowledges receipt of the ruling and tells Ickes he's referring the matter to the city's Public Utilities Commission. [...]
1988: On New Year's Eve, the newly elected mayor, Art Agnos, is summoned to PG&E headquarters to meet with Dick Clarke, who tells him the facts of life: PG&E controls enough votes on the Board of Supervisors to block any effort at promoting public power. The contracts can't be changed and will never be stopped. And if Agnos doesn't want to play ball, PG&E will crush his political career. The city's budget analyst reports that the contracts are a bad deal and a violation of standard city procedures and takes the unusual step of recommending that the supervisors not approve the deal. A Guardian analysis shows that San Francisco is losing more than $150 million a year to PG&E by failing to comply with the Raker Act and establish a municipal utility. But the board votes 8-3 to go along with PG&E for another 37 and 1/2 years, and Agnos, the onetime public-power advocate who campaigned as an alternative to the pro-downtown politics of the Feinstein era, signs the contracts into law.
