California reduces payments for rooftop solar power — for second time in a year

Ben Christopher and Julie Cart, CALMATTERS

The utilities commission reduced payments to apartments, schools and businesses selling solar power to the grid despite a barrage of criticism. Commissioners say it reverses unfair subsidies.

After months of debate and two postponed votes, California’s utility regulator unanimously voted today to overhaul incentives for owners of apartment buildings, schools and businesses that install solar panels.

The new regulations are the second major step that the California Public Utilities Commission has taken in the past year to reduce power companies’ financial support for rooftop solar. In December, the commission reduced payments to homeowners who sell excess power from newly installed solar panels on single-family homes.

Still, for solar advocates, it could have been worse.

Thanks to a last-minute regulatory tweak, the new rules today stop short of a previous proposal that solar industry groups and housing-related interests warned would result in the “evisceration” of the multifamily solar market.

PG&E unveils first 100% renewable remote power system at Pepperwood Preserve

Mary Callahan, PRESS DEMOCRAT

Pacific Gas & Electric Co. and Pepperwood Preserve unveiled the state’s first fully renewable, stand-alone power system at the nonprofit group’s remote site in the Mayacamas Mountains on Monday — part of the utility’s push to eliminate last-mile distribution lines from especially fire-prone areas.

The new remote, solar-powered system is owned by PG&E and will allow the utility to remove nearly three-fourths of a mile of overhead distribution lines that cascade down a wind-swept hillside. It eliminates, as well, the associated maintenance burden and wildfire liability that power lines in mountainous areas represent.

But it also will serve as a replicable model that can be used in hundreds of other locations to reduce first risk and make for a more resilient power supply, project partners said.

It is part of PG&E’s overall system hardening efforts, developed in the wake of catastrophic wildfires caused by faulty power equipment during extreme winds. Other measures include burying power lines and strengthening power poles and overhead lines.

Petaluma gets $1 million to plant more trees

Jennifer Sahwney, PETLUMA ARGUS-COURIER

The city of Petaluma announced it has received a $1 million grant from the U.S. Department of Agriculture’s Forest Service to expand its tree canopy over the next three years.

The plan is to plant about 2,550 trees, said Wendy Jacobs of ReLeaf Petaluma, a local nonprofit that will undertake much of the day-to-day project management.

The tree-planting initiative is part of the Petaluma Canopy Project, a collaborative partnership between the city and local nonprofits including ReLeaf Petaluma, Daily Acts, Rebuilding Together Petaluma, Point Blue Conservation and Cool Petaluma.

The project will “plant trees around parks, schools, residential areas, and our riverbank, with the aim of restoring native species,” according to a news release.

Part of the strategy is to prioritize areas where the city’s low-income residents live and gather, “which typically have fewer trees than other parts of the city,” the release said.

More trees support the city’s climate goals, reduce carbon dioxide in the atmosphere and decrease noise, water and air pollution. The shade they provide also lowers ambient temperatures, the release said.

After tree trimming declared ineffective, PG&E adopts new wildfire mitigation strategy

Grace Scullion, SACRAMENTO BEE

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.

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.

US residential heat pump sales pass gas furnaces for first time as interest in efficiency tech surges

Robert Walton, UTILITY DIVE

Global energy demand rose 1% in 2022 but the rate of energy efficiency improvements was double the average of the past five years boosted by “surging” sales in more efficient technologies like heat pumps and electric vehicles, the International Energy Agency said in a report Wednesday.
In the United States last year, residential heat pump sales exceeded gas furnaces for the first time, making up 53% of heating system sales.
Sales of electric vehicles grew 55% last year in the United States, and in the first quarter of this year made up more than 7% of new car sales. Globally, EVs made up 14% of new car sales in 2022 and could reach 18% this year, IEA said.

Rural counties wood pellet export scheme raises concerns

Gary Graham Hughes, THE NORTHCOAST ENVIRONMENTAL CENTER

Over the first months of 2023 Humboldt County has taken on a leadership role in a massive scheme that aims to export wood pellets from California to global bioenergy markets.

In January, Humboldt County Supervisor Rex Bohn, who is the official delegate of Humboldt County to the Rural County Representatives of California (RCRC), an organization of some 40 rural counties from around the state, was appointed to the Board of Directors of Golden State Natural Resources. The five-person board also includes supervisors from Inyo, Modoc, Siskiyou and Butte Counties.

Golden State Natural Resources (GSNR), an “affiliated entity” of RCRC, is a wood pellet manufacturing and export scheme that proposes to construct two new facilities, one each in Tuolumne and Lassen Counties, to manufacture 1,000,000 tons a year of wood pellets. GSNR would then move those wood pellets by rail to ports in Stockton and Richmond for export by ship to markets in Asia, Latin America and Europe.

Increasingly, because of political convenience and carbon accounting loopholes, coal powered electricity generating facilities are converting to burning biomass. This global trend has continued despite the growing body of evidence that shows that wood pellets are a highly carbon-intensive, polluting, expensive, and inefficient energy source.

Even as the imperative to stop burning coal is becoming clearer by the day, the switch to biomass is climate suicide. Per unit of electricity produced, burning wood coughs up more carbon emissions at the smokestack than burning coal.

In fact, greenhouse gas emissions and air pollution would be emitted at every step of the GSNR project, exposing this wood pellet export scheme as a losing proposition for the climate.

Cutting forests, trucking trees long distances, chipping the wood, manufacturing pellets, transporting the pellets by rail hundreds of miles to ports, and shipping the pellets to be burned overseas — every single one of these steps would be a significant source of climate pollution.

3 new-tech geothermal plans to be considered for boosting power at The Geysers

Jeff Quackenbush, NORTH BAY BUSINESS JOURNAL

Three cutting-edge technologies that could give California a big boost in always-generating emission-free electricity are being eyed for pilot projects in and around massive geothermal field straddling Sonoma, Lake and Mendocino counties.

The Sonoma Clean Power board, made up of public officials from city and county governments the utility serves in Sonoma and Mendocino counties, on March 2 is set to consider cooperation agreements with Canada-based Eavor Technologies, Chevron New Energies and Salt Lake City-based Cyrq Energy. Each agreement calls for building a demonstration power project, each capable of generating up to 20 megawatts If successful, each plan would scale up to production of 200 megawatts.

The agency’s Community Advisory Committee on Feb. 16 recommended board approval of the agreements.

If the three pilot projects are successful, the full-scale projects producing a combined 600 megawatts would move California toward its goal of 1,160 megawatts of new geothermal power generation over the next five years. It would also increase by 85% the current roughly 700 megawatts of power output from existing plants in The Geysers.

Op-Ed: California’s problems won’t be solved by building in wild areas

THE WASHINGTON POST

The Feb. 10 news article “Gentrification by fire” raised valid points but did not address some important issues on building housing in California’s wildland-urban interface.

California’s policies concerning development in the wildland-urban interface are incoherent. The Board of Forestry and Fire Protection, whose members are appointed by California Gov. Gavin Newsom (D), has issued minimum fire-safe regulations. For more than 30 years, the rules have required roads accessing new development to be wide enough so that incoming firefighting apparatus and fleeing civilians can pass each other concurrently. New development on dead-end roads more than a mile long is forbidden. In the past two years, the board was heavily lobbied by counties (including Sonoma County) and developers opposing road limitations for building in the wildland-urban interface, and the board proposed to eviscerate the regulations to allow commercial and residential development in fire-prone areas without safe evacuation routes. This approach failed when a group of retired firefighters lambasted the board’s willingness to jeopardize the safety of firefighters and the public.

Sound regulations remain in place, but the state does not enforce them, letting local jurisdictions ignore many of their protections. California’s housing crisis will not be solved by building in fire-prone rural areas; rather housing needs should be addressed by building as infill near transit hubs and safe evacuation routes.

Gentrification by fire

Scott Wilson, THE WASTHINGTON POST

The West’s new climate is exacerbating housing inequality in the quintessentially blue state of California.

Many of the victims have been left without adequate insurance or financial means to rebuild. Those who remained are in large part the well-off and the well-insured, a trend helping remake and re-sort communities across the state by rich and poor.

SANTA ROSA, Calif. — Climate change and its most extreme consequences are pushing up the price of homes throughout much of the American West, as fires and flooding carve into existing housing stock and restrict the amount of land suitable for future building.

Over several harrowing weeks in October 2017, the Tubbs Fire swept over this city’s eastern hills to destroy about 5,600 homes, an estimated 5 percent of the region’s already threadbare housing stock. Twenty-two people died in the flames.

It was the first mega-fire of California’s new mega-fire era, a flashing red light along the West’s path into a new climate. The Tubbs Fire was also the start of a new kind of economic gentrification, one caused by the increasingly harmful effects of climate change, the higher costs of rebuilding and insuring homes in fire-prone areas, and a housing stock diminished by fire and flooding.

The results have undermined California’s push to build more affordable housing, a goal set by Gov. Gavin Newsom and the rest of a state Democratic leadership, whose political ethic has made a priority of narrowing the gap between rich and poor, an imbalance particularly pronounced in the nation’s most populous state.

Sonoma County airport electric-car-rental plan faces power-supply bottleneck

Jeff Quackenbush, NORTH BAY BUSINESS JOURNAL

A plan for electric-vehicle fast chargers at an envisioned new car-rental facility at the Charles M. Schulz–Sonoma County Airport has hit a speed bump: A power provider says it could take several years to provide the large amount of electricity those chargers require.

The facility proposal is being updated for EV rentals to fit with California’s recently accelerated push to electrify transportation to cut emissions.

But a local bottleneck in the electrical grid has the project team exploring ways to lessen the anticipated multi-megawatt power demand from chargers needed to quickly get returned EVs ready for the next renter.

Plans for the consolidated rent-a-car facility have been in motion since late 2019, according to documents presented to the Board of Supervisors early this year. The five rental companies operating at the county-run airport want to increase the number of vehicles available and add joint services such as fueling stations for the fleets, automated car wash and a shop for light maintenance.
