As solar grew in CA batteries were added to store excess midday energy and release it during evening peak demand, addressing the "duck curve"

This chart shows how California is massively extending solar use into the evening

As solar energy became a larger and larger portion of California electricity generation, there were rising concerns about the infamous “duck curve.” Solar energy was starting to dominate midday electricity generation, forcing curtailments even, while peak electricity demand in the evening was a tad too late for solar to be helpful.

The core solution, of course, was for batteries to come in and soak up extra midday electricity generation and then disperse it in the evening. Thus, California has installed a lot of battery storage on the grid in the past few years.

Amid 100°F heat, California avoided emergencies, thanks to a battery boom that now bolsters the nation's top solar power producer.

Batteries power California’s newly reliable grid

California has long been an easy mark for Republicans eager to criticize clean energy policies.

The nation’s most populous state struggled with rolling blackouts in a 2020 heat wave, handing political fodder to opponents of California’s ongoing transition to a carbon-free grid. Then-President Donald Trump accused Democrats of “forcing Americans in the dark.”

But four years later, how the tables turn.

Warehouses, commercial areas, shopping centers and factories are perfect for solar and battery power stations.

How warehouses and shopping centers could produce 25% of Australia’s power

Imagine if Australian cities became major producers of clean energy, rather than relying on far-flung solar and wind farms.

Far fetched? Hardly. Our cities and towns are full of warehouses, commercial areas, shopping centers and factories. These types of buildings have one very important underutilized resource—large expanses of unoccupied rooftops, perfect for solar and battery power stations.

If our commercial and industrial areas took up solar and storage, it would be revolutionary. Electricity could be produced in cities and used in cities, reducing transmission losses. Commercial businesses could generate solar power during the day, store it in batteries on site and sell it back to the grid during the evening peak.

California’s record 10GW of grid batteries are finally pushing solar generation into post-sunset hours at a meaningful scale, new data shows.

Batteries are taking on gas plants to power California’s nights

California spent the last decade building up a massive fleet of batteries to help clean up its electrical grid. This spring, those storage plants passed a major threshold, and now are visibly reshaping the state’s power grid — just as clean energy advocates said they would.

Governor Gavin Newsom announced in late April that California hit the 10 gigawatt mark for installed battery capacity, well beyond what any other states — or entire countries — have achieved. That’s about 13 times more battery capacity than the state had installed just five years ago, and it’s enough to make batteries a meaningful portion of the state’s power supply. For reference, 10 gigawatts are enough to meet about 20 percent of the peak electricity demand recorded in the grid managed by the California Independent System Operator (CAISO).

Giant batteries are delivering solar power after dark in California and helping to stabilize grids in other states.

Giant batteries are transforming the way the US uses electricity

California draws more electricity from the sun than any other state. It also has a timing problem: Solar power is plentiful during the day but disappears by evening, just as people get home from work and electricity demand spikes. To fill the gap, power companies typically burn more fossil fuels like natural gas.

That’s now changing. Since 2020, California has installed more giant batteries than anywhere in the world apart from China. They can soak up excess solar power during the day and store it for use when it gets dark.

The US is rapidly adding batteries to store energy at large scale. Increasingly, these are getting paired with solar and wind projects.

Across the US, batteries and green energies like wind and solar combine for major climate solution

In the Arizona desert, a Danish company is building a massive solar farm that includes batteries that charge when the sun is shining and supply energy back to the electric grid when it’s not.

Combining batteries with green energy is a fast-growing climate solution.

“Solar farms only produce when the sun shines, and the turbines only produce when the wind blows,” said Ørsted CEO Mads Nipper. “For us to maximize the availability of the green power, 24-7, we have to store some of it too.”

The next wave of clean-tech adoption must focus on non-lithium batteries and take advantage of safe, affordable chemistries.

California’s new net-metering policy brings batteries to forefront

California’s net-energy metering (NEM) policy has been a key driver of the state’s solar deployment, incentivizing adoption by allowing utility customers to sell excess power generated from rooftop solar back to the grid for a profit. With approximately 1.5 million homes and businesses participating, policies like this have made California a clean energy leader in the United States, and even the world. However, the California Public Utilities Commission recently changed the solar-friendly policy.

The approved new framework (known as NEM 3.0) is expected to slash the rate paid for solar energy sold back to the grid by 75%. This revision significantly lengthens the five- to seven-year average payoff period for installing solar and puts the growth of solar power at risk. Californians must embrace an additional clean energy technology in order to shorten payoff periods and continue the momentum behind solar: batteries.

US energy storage industry has met many milestones in recent years, but 2023 should be a banner year for battery adoption across all markets.

With more compensation and incentive options, energy storage adoption is on the rise

The U.S. energy storage industry has met many milestones in recent years, but 2023 should be a banner year for battery adoption across all markets. Thanks to the new storage investment tax credit (ITC), systems of any size have access to a 30% installation credit.

Research firm Wood Mackenzie is forecasting 59.2 GW of energy storage capacity to be added through 2026, up from the market’s 13.5-GW cumulative capacity in 2022.

“The U.S. energy storage industry is reaching maturity,” said Jason Burwen, VP of energy storage at the American Clean Power Association, in a press release. “Energy storage is now regularly being installed at over 1 GW per quarter. Combined with the tailwinds of newly available tax credits from the Inflation Reduction Act, the question for investors and grid operators now is not whether to deploy storage, but how much storage to deploy — and how fast.”

Newly developed software allows the management of thousands of residential batteries, which, if used collectively, become a virtual power plant.

Residential batteries linked over internet could soon help California’s electrical grid

It has been less than a year since Andrea Divis moved back to San Diego County into a two-story Oceanside home.

“It’s comfortable and cozy, and really, the backyard is kind of like my oasis,” Divis said.

She deals with a chronic medical condition that does not allow her to go without air conditioning or refrigeration for her medicines.

“When I was in Oregon, I was paying, I don’t know, $150 a month for my utilities,” Divis said. “And now I come here, and on the lowest month, it was $200, and I got upwards of $450, $480.”

Divis saw solar as a solution. She added power-generating panels to her roof, and just inside her garage, there is a new Sonnen battery.
