Solar Arrays are Great, But Big Batteries are Better
Last spring California quietly achieved a milestone that, despite its ramifications for homeowners, businesses, and the planet itself, generated few if any headlines: the use of battery-stored energy surpassed that of natural gas.
In other words, California homes and businesses are now pulling more energy from battery storage systems than from natural gas solutions. And with the cost of batteries plummeting by as much as 80-90 percent, there is little reason to think other sun-drenched states won’t soon be following suit.
The numbers in California are startling. Just five years ago California had 770MW of battery storage. Today that figure is nearly 10.4GW and by year’s end may top 14GW. Since 2020, California has installed more batteries than any other part of the world except for China.
Historically, California has depended on natural gas, nuclear power, hydroelectric services to feed its massive appetite for energy. Batteries – and the green energy solutions that keep them fed – are eating into the market share of those solutions. And bringing cleaner air with them.
“As we’re building more solar and batteries and other renewables on the grid, we’re seeing more and more reductions of gas, and eventually the gas will be eliminated,” said Mark Jacobson, a professor of civil and environmental engineering at Stanford University. “There was an eclipse on April 8, when solar supply went down precipitously for a couple of hours and immediately the batteries kicked in and replaced the solar.”
There’s an old saying that ‘where California goes, America follows.’ That may prove particularly true when it comes to battery storage systems. As the nation’s most populous state races toward a net-zero future, other states are paying attention.
And it’s not as if battery storage systems are an option. With the nation’s aggressive push toward renewable energy solutions, batteries necessarily come with that move. “If you want more renewables on the grid, you need more batteries. It’s not going to work otherwise,” said Andrés Gluski, chief executive of AES Corporation.
As for California, the state is keeping the proverbial pedal to the metal. Huge new investments are being made in solar and battery production to ensure the state reaches its 2045 net-zero goal.
And it should be noted that the Golden State isn’t alone. Texas recently passed California as the nation’s leading generator of solar power.

We’re excited to announce that Pasture Voltaics LLC and its unique SunTracker technology have joined the PlanitWorks partner family.
Using raised, high-tensile cables positioned nine feet above the ground to control a solar grid array to track the sun, SunTracker enables ranchers, farmers, Native American tribes, and other entities with vested land management interests to:
- Provide green energy development
- Protect their herds from excessive heat
- Regenerate land
- Feed power back to the grid
The elevated, cabled solar canopy is particularly ideal for livestock, because they provide badly needed shade (for animals and the land), thereby reducing stress on the animals and mitigating evaporation.
A typical 1,200-acre installation generates up to 200MW of electricity. Additionally, the cabling systems are based on well-known bridge-building principles, enabling them to withstand the kinds of high winds typical on open ranges.
While Pasture Voltaics does the actual instllations, PlanitWorks is managing all development efforts including planning, permitting, and working with ranchers.

Federal hurdles, including onerous fees and development delays, are seriously hampering tribal nations’ efforts to implement ambitious alternative energy projects that could generate reliable power, new jobs, clean energy, and massive new economic opportunities.
Although the Inflation Reduction Act (IRA) committed hundreds of billions to support clean energy initiatives across the country, a perfect storm of interconnection requirements, a high volume of complex interconnection requests, and Federal Energy Regulatory Commission (FERC) fees to remain in the development queue have all conspired to create a logjam in the system.
This has proved particularly challenging for many tribes, which are looking to alternative energy solutions,(e.g., solar, wind, and geothermal) as reliable sources of power rather than purely green power initiatives.
“Tribes are unfairly being lumped into the same pool as speculative developers,” says Brian McLaughlin, CEO of PlanitWorks. “At the end of the day, these communities simply want access to reliable power. Understandably, they’d like to take charge of their own energy destinies.”
Big Fees Are Impeding Progress
Per FERC’s Order 2023, within 14 to 30 days, all interconnection requests must be accompanied by a commercial readiness deposit of $5 million (reduced from an original $7.5 million). These fees are designed to limit speculative requests from developers that are actually unprepared to perform the work or that abruptly withdraw (the $5 million would cover withdrawal penalties).
But for most tribes, coming up with that kind of money on such short notice is all but impossible. And to reiterate, the tribes aren’t interested in speculating, they’re interested in generating reliable power.
In its August 2023 report to Congress, DOE’s Office of Indian Energy released the results of a tribal survey showing that 72% of tribes had no ownership or control of their electrical infrastructure. The survey also revealed that tribes suffered an average of 10.5 power outages per year compared to a national average of just 1.6 annual outages.
In other words, far from dabbling in speculative bidding for interconnection opportunities, the tribes simply want access to, and some modicum of control over, a reliable power source.
“If you have homes that don’t have electricity in them, do you believe that they’re really thinking about clean energy,” asks Onna Labeu, the Indigenous Power & Light Fund’s managing director and the former director of the Office of Indian Economic Development at the U.S. Department of the Interior.
Labeu added that while it’s understandable the federal government is focused on reducing emissions, it’s important to remember “there are communities that are way ahead of everybody else, but the tribal communities are significantly behind.”
Reliable Power is the Focus
Ironically, Order 2023 is designed to accelerate the approval process for interconnection requests. According to a report by the Berkeley Lab of the Lawrence Livermore Laboratory, the number of requests in recent years has exploded, most in solar, wind, and storage.
Today more than 10,000 projects (a 40% year over year increase) representing roughly 1,350GW of power generation and another 680GW of storage await approval to connect to the grid. Because part of that effort to speed up things includes the hefty fees to ward off speculative types, tribes are asking for an exemption.
“We have petitioned FERC on behalf of the tribes we serve to waive [or defer] the commercial readiness deposit … and to allow tribes to remain in the interconnection queue,” said Chéri Smith, CEO of the Alliance for Tribal Clean Energy.
She noted that large alternative energy projects are “big economic engines” that not only could produce reliable sources of energy, but also generate new jobs and other economic opportunities.
Despite what may seem like a steady drumbeat of bad news regarding electric vehicle (EV) sales and leases, the industry is actually enjoying sufficient growth to suggest it soon may achieve a 10 percent share of the domestic auto industry.
Kelley Blue Book estimates EV sales in the third quarter hit 346,309 units, reflecting a year over year growth rate of 11%. EV sales also established new volume and market share records. Even Tesla, which struggled in the first half of the year, enjoyed strong growth in Q3.
Stephanie Valdez Streaty, director of Industry Insights at Cox Automotive, acknowledged much of that growth was likely due to an aggressive slate of government and industry incentives and discounts (at 12%, industry incentives for EVs were significantly higher than the 7% offered for other vehicle types).
But Valdez Streaty believes that “as more affordable EVs enter the market and infrastructure improves, we can expect even greater adoption in the coming years.”
What is perhaps most important is that EV’s domestic market share climbed to 8.9% compared to last year’s rate of 7.8%, leading industry observers to believe a 10% market share may not be far off.
