On July 9 at 7:35 p.m., California’s energy grid hit an all-time peak for battery storage.
However that file is simply the primary of many. All-time peaks—like the two,519 megawatts on that night—are going to be occurring with regularity as extra battery storage techniques come on-line. What’s extra attention-grabbing is the event of the tasks which can be serving to to set these data, and the implications for remodeling the grid into one which doesn’t want fossil fuels.
The large kahuna in California’s battery fleet is Moss Touchdown Power Storage, with 400 megawatts of capability and the flexibility to run at that stage for as much as 4 hours, discharging 1,600 megawatt-hours earlier than needing to be recharged. The plant is again in motion after a chronic interval when it was barely operating.
California had 3,100 megawatts of utility-scale battery storage techniques as of April, which was far and away essentially the most within the nation, in accordance with the Power Data Administration. About 80 % of that capability is from techniques that went on-line since 2021.
This month, day by day peaks of two,000 megawatts have develop into strange, however the state’s batteries hit 2,000 megawatts for the primary time simply two months in the past, on Could 22, proper across the time Moss Touchdown was working once more after months of repairs and troubleshooting. (For perspective, 2,000 megawatts is concerning the capability of a giant coal, gasoline or nuclear energy plant, so we’re nonetheless speaking a couple of small share of the electrical energy provide.)
It was solely a yr in the past that the state’s battery techniques collectively hit their first peak of 1,000 megawatts, in accordance with figures from the California Unbiased System Operator, the nonprofit that runs the grid overlaying a lot of the state.
As battery storage crops develop into extra frequent, then what are they changing?
The reply is pure gasoline energy crops, stated Ric O’Connell, founding govt director of GridLab, a nonprofit in Berkeley, California that gives clear power experience to advocates and policymakers.
“We’re counting on these batteries to principally retailer the surplus power from photo voltaic in the course of the day, after which discharge later within the day when the photo voltaic is dropping off,” he stated.
However batteries nonetheless have a protracted solution to go to make a critical dent within the demand for gasoline. When battery use was peaking on July 9, pure gasoline energy crops have been offering greater than 13,000 megawatts to the grid.
O’Connell stated battery techniques are initially going to displace the oldest and least environment friendly gasoline crops.
GridLab has been finding out how California can transfer towards a cleaner grid, together with a report issued in Could that reveals pathways for getting the state to 85 % carbon-free electrical energy by 2030. All of them embrace massive will increase in photo voltaic and batteries.
“We predict we will retire most likely half the gasoline (energy crops) within the state and nonetheless be dependable,” O’Connell stated. By that, he implies that gasoline crops can proceed to shut as different assets come on-line over the rest of the last decade.
But when grid operators are going to rely way more on battery storage, they should be assured that these techniques can carry out. Because of this storage builders have to be taught from the issues Moss Touchdown has skilled.
Vistra Corp., the Texas-based proprietor of the challenge, introduced in January 2021 that the primary part of the Moss Touchdown challenge had completed building and was linked to the grid, with 300 megawatts of capability. The corporate described the challenge as the most important battery storage facility on the planet.
At the moment, the battery system spanned the size of practically three soccer fields, housed inside a refurbished constructing that was once a part of a pure gasoline energy plant. The system’s 4,500 battery racks might energy about 225,000 homes, Vistra stated.
Then, in April 2021, the corporate introduced that it had accomplished the second part of the challenge, including 100 megawatts to convey the full to 400.
However the challenge didn’t start discharging electrical energy into the grid for months, in accordance with the Power Data Administration, which reveals no output from the plant till June 2021.
After that, the plant was offline or operating at solely a fraction of its capability from November till April, the newest month for which data was out there.
Vistra stated in September that it had an incident on the plant by which sprinklers had gone off and broken among the batteries.

In January, the corporate launched the outcomes of an investigation that traced the issues to a defective ball bearing in an air dealing with unit, which launched smoke and triggered the sprinkler system. The smoke wasn’t coming from the batteries, however the sprinklers doused among the batteries, damaging them and inflicting them to overheat, which launched much more smoke.
Lithium-ion batteries are extremely flammable, so any incident involving warmth and smoke is a priority, however Vistra stated it was capable of cope with the issue by itself with none accidents to workers. The report included corrective actions to cut back the probabilities of a recurrence.
Then, the plant had one other incident on Feb. 13 by which the discharge of smoke led to a shutdown. The native fireplace chief stated the scene was much like what he had seen in September, with moist batteries and melted plastic across the battery racks, as reported by Monterey County Weekly. Quick ahead to July 11, when Vistra stated it had resolved the issues and had practically the entire plant’s capability on-line for the summer time.
Now Moss Touchdown is operating, and Vistra is engaged on a 3rd part that will add one other 350 megawatts and could possibly be full by subsequent summer time.
Right here’s hoping that the plant can put collectively a monitor file of reliability to go together with its notoriety for being the most important.
Different tales concerning the power transition to pay attention to this week:
After Manchin Rejects Local weather Provisions of ‘Construct Again Higher,’ What’s Subsequent?: Sen. Joe Manchin, the West Virginia Democrat, has stated he gained’t assist the local weather and clear power provisions in a proposed spending invoice that the Senate Democrats have been struggling to cross. The obvious loss of life of these provisions implies that clear power industries gained’t be getting among the funding they’d hoped for and shoppers gained’t get a beefed-up tax credit score for electrical autos. On Wednesday, President Joe Biden was in Massachusetts to speak about his local weather agenda, as ICN’s Marianne Lavelle studies. He warned Congress that if it doesn’t act, he’ll transfer ahead along with his local weather agenda via govt actions.
Postal Service to Quadruple Order for Electrical Autos: The U.S. Postal Service stated on Wednesday that it’ll electrify a minimum of 40 % of its new supply fleet, a rise from the earlier pledge to affect 10 %. The shift is a victory for local weather activists who’ve steadily pushed for al Service to extend its dedication to EVs, as Jacob Bogage studies for The Washington Put up. “al Service reiterates its dedication to the fiscally accountable rollout of electric-powered autos for America’s largest and oldest federal fleet,” the company stated.
GM’s Mary Barra Talks Electrical Autos: The Normal Motors CEO shouldn’t be backing off of her audacious prediction that by the center of this decade her firm will promote extra EVs than Tesla. She stated she’s assured that GM can beat Elon Musk in creating high-range EVs that individuals can afford, as Tom Krisher studies for the Related Press. GM has already stated it should reduce the beginning worth of the Chevrolet Bolt EV to $26,000 by the tip of this yr. “To essentially get to 30, 40, 50% EVs being bought, it’s important to enchantment to individuals which can be in that $30,000 to $35,000 worth vary,” Barra stated.
In Indiana, Photo voltaic Web Metering Guidelines Go from Dangerous to Worse: Indiana photo voltaic installers have been anticipating their prospects to be worse off when new, lowered charges for extra photo voltaic era took impact on July 1. However the modifications made by utilities go far past these expectations, and photo voltaic advocates argue that utilities have exceeded the parameters of a 2017 state regulation that changed the principles for photo voltaic compensation, as Kari Lydersen studies for Power Information Community. Advocates at the moment are difficult the principles in court docket. Indiana is considered one of many states the place utilities are attempting to cut back the monetary advantages of photo voltaic, together with by lowering the compensation that photo voltaic house owners obtain for promoting extra electrical energy again to the grid.
U.S. Photo voltaic Firm to Open a Photo voltaic Shingles Plant in Texas: U.S. photo voltaic firm GAF Power stated it should open a brand new manufacturing facility in Texas to make residential photo voltaic roof shingles, selecting to construct in the US reasonably than in China. The announcement comes at a time of rising considerations in the US concerning the reliance on Chinese language-made photo voltaic merchandise, as Nichola Groom studies for Reuters. The manufacturing facility, which can have about 260 workers, is a part of a broader push to popularize the concept of shingles that generate electrical energy. Tesla is among the many different corporations that’s making a photo voltaic roof product.
