PG&E Corp. is axing its enhanced tree-trimming program aimed at reducing wildfire risk after deeming it largely ineffective, the Wall Street Journal reported.

The $2.5 billion program thinned and cleared more than one million trees near power lines across Central and Northern California since it went into effect in 2019, the newspaper said after interviews with executives.

Pacific Gas & Electric, which provides electricity and gas to 16 million across the state, credited the program with reducing total fire ignitions by 7% and ignitions during the fall fire season by 13%.

The embattled utility, which has been blamed for several of California’s worst and deadly wildfires, said it would still trim its backlog of about 385,000 potentially hazardous trees that have yet to be cleared — an effort expected to take nine years.

The Oakland-based company also said it would continue its regular tree-trimming maintenance. Twice per year, the company inspects trees around power lines for hazards. It is also piloting a targeted tree-trim program focused on heavily forested areas of the Sierra Nevada foothills.

Since 2017, Pacific Gas & Electric (PG&E), California’s largest utility, has racked up more than $30 billion in liabilities for wildfire-related damages caused by its equipment. In January 2019, PG&E filed for Chapter 11 bankruptcy protection with the goal of shedding these liabilities.

This grave situation also represents a golden opportunity for the Golden State.

Experts have been weighing in on what should become of PG&E. Ideas include making PG&E a public authority controlled by the state, breaking it up into municipal utilities, and making it a fully deregulated utility.

But there’s a better solution, one that should be applied to all the state’s investor-owned utilities (IOUs): require the utilities to divest their transmission assets. This solution avoids another utility bailout, protects utility customers from rate increases and wildfire risks, and fixes a major obstacle to California’s zero-emission, clean energy future.

A broken business model

The current utility business model is fundamentally broken and needs to change. IOUs now earn a guaranteed rate of return on infrastructure investments, which incentivizes them to build more transmission infrastructure and has led to out-of-control transmission costs around the country.

Because transmission costs are the fastest-growing part of electricity bills, it could soon cost more to deliver energy than to generate it. And it’s worse than it looks.

The capital costs of transmission infrastructure, high as they are, represent a fraction of total transmission costs. Operations and maintenance (O&M) and returns on investments drive up transmission costs significantly over the life of these assets, with those excessive costs borne by ratepayers.
