(Bloomberg) -- Utility giant PG&E Corp. capped its best day since going bankrupt in January thanks to California’s governor.

Gavin Newsom called on lawmakers on Friday to find a way to help the state’s utilities cover the costs of devastating wildfires -- costs so crippling that PG&E was forced to file for Chapter 11 in January while facing $30 billion in liabilities. He issued a report outlining possible solutions -- including an insurance fund utilities could tap into -- sending the clearest signal yet that California will move to keep its power companies solvent.

“We all have a burden and a responsibility to assume the costs," Newsom said in a news conference when the report was released. As a result of the wildfires, he said, “We are in a very precarious state.” Newsom, a Democrat, asked for legislation to be passed by July 12. His party holds the majority in the state legislature.

In doing so, Newsom delivered what Wall Street has been waiting on for months: Clarity on exactly what the state will do to help utilities, including Edison International and Sempra Energy, avoid the same fate as PG&E. Edison’s Southern California Edison utility and Sempra’s San Diego Gas & Electric have both seen their credit downgraded due to the wildfire risks and face junk status within months without a fix from the state.

PG&E, which didn’t immediately respond to a request for comment, jumped 21 percent to $23.08, its highest close since Jan. 24. Edison surged 7.2 percent at $67.13, and Sempra gained 1.4 percent.

While he called for action to aid utilities, Newsom wasn’t shy in addressing PG&E’s culpability during a press conference. He raised the idea, on several occasions, of a possible government takeover should PG&E continue to be “bad actors” and “mislead” the state. Newsom noted that, in the report, “there is a word that drives shivers up people’s spines: It’s called municipalization.” And, he added, “If they don’t get it done. We will get it done.”

Newsom’s report outlines policy options that include a catastrophic wildfire fund utilities could use for liabilities and a liquidity fund. It doesn’t make an outright recommendation on whether the state should kill a legal doctrine known as inverse condemnation that holds utilities strictly liable for damages should their equipment cause a fire. But it does suggest that lawmakers consider changing the doctrine to a “fault-based standard” that would make utilities responsible if there was misconduct involved.

Newsom’s report drew a mixed reception. Key lawmakers pledged to work with him, with Senate President Toni Atkins saying legislators will “dive into the details” of the report in the coming weeks. Advocacy group Consumer Watchdog meanwhile said a “PG&E bailout shouldn’t be buried in the fine print of legislative action.”

While California’s utilities rallied, Moody’s Investors Service said the impact on the companies’ credit remains to be seen. “The report represents concrete progress toward options for managing wildfire risk – a credit positive,” the ratings company said. While Moody’s said none of the report’s suggestions alone would mitigate utility risk, “combined, the strategies start to exhibit more promise.”

Other reactions:

• “This can’t be a bailout for the utilities, nor can it allow them to continue ‘business as usual,’ or duck responsibility for the catastrophic damage they’ve caused,” said Patrick McCallum, a lobbyist for wildfire victims and their lawyers.
• “Customers obviously can’t afford to bail PG&E out of billions in liabilities when it is negligent,” said Mark Tony, executive director of the Utility Reform Network. “We’re already paying top dollar for fire safety, although PG&E isn’t delivering.”
• SoCalEd said in a statement that it’s “encouraged" by the broad scope of Newsom’s report, adding that it “appropriately reflects the need to address wildfire liability and regulatory reform.”
• Sierra Club praised Newsom for making clear that the state remains dedicated to fighting climate change and that “there will be no jailbreak from commitments to transition to clean, renewable energy.”
• “At the end of the day, we need stability in our utilities to keep the lights on,” said California Assemblyman Chris Holden, who helped write legislation last year assisting utilities.
