Slashing emissions from dirty diesel backup systems, the use of which is growing, is the focus of energy and air quality regulators. Diesel generation is widely used because it is cheap, accessible, and established. Panelists at a joint agency workshop tout alternative technologies fueled by gas, more so when supplied with renewable gas or green hydrogen. But hurdles remain.

The Federal Energy Regulatory Commission has a new chair...

A potential air quality crisis in the state best known for pollution regulation pushed the California Energy Commission into a full day forum Thursday on alternatives to diesel generators.

The use of backup generators has soared in California with the growing frequency of preventive power outages during climate-exacerbated fire conditions. That includes large diesel projects recently permitted by the Energy Commission and hundreds of megawatts of utility diesel generators approved by the California Public Utilities Commission...

One of the avenues for helping secure power supplies during safety shutoffs and heat waves is a proceeding on clean microgrids. But a new California Public Utilities Commission decision makes little headway on advancing the microgrid market because of concerns about ratepayer costs and safety. Those concerns do little to appease low-income advocates who object to putting private utilities in the driver’s seat...

Correction made Jan. 21

Half of California’s sole remaining nuclear plant, Diablo Canyon, is offline for the third time in six months, and it's not expected to be back in continuous service for several more weeks. The plant’s 1,150 megawatt Unit 2 went down Dec. 2.

Both of the unit's two unplanned outages earlier last year were due to a hydrogen leak from an electric component at Pacific Gas & Electric’s plant...

Federal energy regulators shoot down a proposed order requiring the grid operator to prove the August outages were not caused by its unreasonable tariff. Two of the three voting Federal Energy Regulatory Commission members reject interfering with the California Independent System Operator's work with state energy agencies to fill grid reliability gaps.

The California Public Utilities Commission approves lower electric vehicle charging rates, more EV investments in disadvantaged communities and inching ahead on vehicle to grid projects...

The California grid operator dodged a bullet Dec. 17 when federal regulators voted down an order that would have required the California Independent System Operator to prove its mid-August outages were not caused by an unreasonable market tariff.

Federal Energy Regulatory Commission member Rich Glick said FERC has already exacerbated problems in three eastern regional transmission organizations and shouldn’t intervene in California's market, which integrates large amounts of renewable power...

What is the best way to mix in growing levels of intermittent renewable resources in networks such as California's, as it marches towards a 100% clean energy portfolio by 2045? Among the usual suspects are better interconnections, and more generation diversity, including more storage and price responsive demand, a resource traditionally neglected. A newly released book, Variable Generation, Flexible Demand, provides a broad lens on the subject...

The Diablo nuclear power plant’s Unit 2 shuts down just two days after it goes back online over the Thanksgiving holiday weekend. The $100 million rebuild of the electric generator part malfunctions for a third time. A watchdog wants to know the cause, who is on the hook for the repair and whether there will be heightened monitoring.

A little more than a day later, the California Public Utilities Commission approves Pacific Gas & Electric’s request for an additional $9 billion in revenue this year, and more the next two years...

One of two main units at the Diablo Canyon Nuclear Power Plant is down for the third time. Soon after Unit 2 was restarted over the Thanksgiving weekend after a month-and-a-half long outage, Pacific Gas & Electric again had to take it offline. The problem continues to be with an electric generator component that was rebuilt last year.

"Operators have previously taken the unit offline twice this year to allow for needed maintenance on this component, which had been refurbished in 2019 and is located on the non-nuclear side of Unit 2," PG&E stated the evening of Dec...

State utility regulators aim to move on demand side resources to avoid outages when it is roasting hot next summer. They plan to take the unusual step of expediting changes to California Public Utilities Commission resource adequacy, demand response and other load reduction programs.

Over at the nation’s capital, the Federal Energy Regulatory Commission holds its first post-election meeting. The demoted Republican Chair Neil Chatterjee stands by his decision to support carbon pricing...

Pacific Gas & Electric pitches a plan to transfer $7.5 billion of shareholder debt to ratepayers, which gets raked over the coals. Consumer advocates argue that substituting long-term ratepayer-backed bonds for the bankruptcy debt puts customers' pocketbooks at risk and fails to meet legal requirements. Those mandates include that the financing be rate neutral and boost the utility’s chances of attaining investment grade ratings...

Neil Chatterjee, who has served as the Federal Energy Regulatory Commission chair for more than two years, is suddenly replaced. President Trump late Thursday names James Danly the new FERC chief.

In blue California, state utility regulators approve Southern California Edison’s plan to issue $337 million in ratepayer-backed bonds to recover the costs of making its system more fire resilient. The California Public Utilities Commission also suspends a controversial multi-million- dollar bonus program for shareholders for squishy energy savings...

The rolling blackouts, according to the Preliminary Report on Causes of August Rotating Outages, were fundamentally caused by a California Independent System Operator software glitch and community choice agencies, utilities and direct access providers collectively under-scheduling customer demand in the Day-Ahead Market by ~7% to 8% on Aug. 14 and 15.

Ordinarily the under-scheduling wouldn’t have been a problem because how much demand Load Serving Entities choose to schedule in the Day Ahead Market should never impact the stability of the market—by design...

Bureaucratic red tape at the California Public Utilities Commission prevented East Bay Community Energy from contracting for clean, behind-the-meter electricity last year that could have provided power or lowered demand during the August heat waves. The resources were designated to help meet East Bay’s 2020 resource adequacy obligations. The community aggregator says it also is hitting a wall with regulators who have limited its ability to invest in clean demand response and capitalize on aggregated residential solar-plus-storage resources, Stefanie Tanenhaus, EBCE senior regulatory analyst, told Current...

California is striving to attain a clean, reliable, and affordable grid, but getting there requires huge changes—from institutional to technological. Part and parcel of this transition is the age-old battle between the established and the newbies, with the former fighting to hold onto turf and the newcomers struggling to get some viable sod in an evolving landscape.

A prime example is the struggle at the California Public Utilities Commission to advance non-utility owned clean microgrids...

The untimely Oct. 15 shut down of the Diablo Canyon nuclear plant’s Unit 2 is the second malfunction in a critical component of its electric generator, which was just rebuilt. In July, the same Pacific Gas & Electric unit was forced offline because then, as now, the cooling system that lowers the extreme heat inside the spinning generator was leaking hydrogen gas, which is the cooling fluid...
