Rhode Island issues its plan to achieve 100% renewable electricity by 2030

California EV V2G explores bi-directional charging, smart charging, and demand response to enhance grid reliability. CPUC, PG&E, and automakers test incentives aligning charging with solar and wind, helping prevent blackouts and curtailment.

Key Points

California EV V2G uses two-way charging and smart incentives to support grid reliability during peak demand.

✅ CPUC studies feasibility, timelines, and cost barriers to V2G

✅ Incentives shift charging to align with solar, wind, off-peak hours

✅ High-cost bidirectional chargers and warranties remain hurdles

California energy regulators are eyeing the power stored in electric vehicles as they hunt for ways to avoid blackouts caused by extreme weather.

While few EV and their charging ports are equipped to deliver electricity back into the grid during emergencies, the California Public Utilities Commission wants more data on it as the agency rules on steps utilities must take to ensure they have enough power for this summer and next year. A draft CPUC decision due to be discussed this week asks about the feasibility of reversing the charge when needed (Energywire, March 8).

“Very few [EVs], maybe a couple of thousand at the most, can give power to the grid, and even fewer are connected into a charger that can do it,” said Gil Tal, director of the Plug-in Hybrid & Electric Vehicle Research Center at the University of California, Davis. EVs that feature the ability “have it at a more experimental level.”

The issue arises as California, where about half of all U.S. EVs are purchased, examines what role the vehicles can play in keeping lights on and refrigerators running and how a much bigger grid will support them in the long term. Even if grid operators can’t pull from EV batteries en masse, experts say cash and other incentives can prompt drivers to shift charging times, boosting grid stability.

“What we can do is not charge the electric cars at times of high demand” such as during heat waves, Tal said.

The EV focus comes after California’s grid manager last summer imposed rolling blackouts when power supplies ran short during a record-shattering heat wave. State energy regulators across the U.S., as EVs challenge state grids, are also looking at their disaster preparedness as Texas recovers from a winter storm last month that cut off electricity for more than 4 million homes and businesses there.

California’s EV efforts can help other states as they add more renewable power to their grids, said Adam Langton, energy services manager at BMW of North America.

That automaker ran a pilot program with San Francisco-based utility Pacific Gas & Electric Co. (PG&E) looking at whether money and other incentives could prompt EV drivers to charge their cars at different times. The payments successfully shifted charging to the middle of the night, when wind power often is plentiful. It also moved some repowering to mornings and early afternoons, when there’s abundant solar energy.

“That can be a tool that the utilities can use to deal with supply issues,” Langton said. “What our research has shown is that vehicles can contribute to [conservation] needs and emergency supply by shifting their charging time.”

Such measures can also help states avoid having to curtail solar production on days when there’s more generation than needed. On many bright days, California has more solar power than it can use.

“As more states add more renewable energy, we think that they’re going to find that EVs complement that really well with smart charging, because grid coordination can get that charging to align with the renewable energy,” Langton said. “It allows to add more and more renewable energy.”

High-cost equipment a hurdle
The CPUC at a future workshop plans to collect information on leveraging EVs to head off power shortages at key times.

But Tal said it will probably take a decade to get enough EVs capable of exporting electricity back to utilities “in high numbers that can make an impact on the grid.”

Barriers to reaching such “vehicle to grid” integration are technical and economic, he said. EVs export direct current and need a device on the other side that can convert it to alternating current, similar to a solar power inverter for rooftop panels.

However, the equipment known as a V2G capable charger is costly. It ranges from $4,500 to $5,500, according to a 2017 National Renewable Energy Laboratory report.

PG&E and Los Angeles-based Southern California Edison already have “expressed doubt that short-term measures could be developed in time to expand EV participation by summer 2021” in V2G programs, the draft CPUC proposal said. The utilities suggested instead that the agency encourage EV owners to participate in initiatives where they’d get paid for reducing power consumption or sell electricity back to the grid when needed, known as demand response programs.

Still, almost all major EV automakers are looking at two-directional charging, Tal said.

“The incentive is you can get more value for the car,” he said. “The disincentive is you add more miles in a way on the car,” because an owner would be discharging to the grid and re-charging, and “the battery has limited life.”

And right now, discharging a vehicle to the grid would violate many warranties, he said. Car manufacturers would need to agree to change that and could call for compensation in return.

Meanwhile, San Diego Gas & Electric Co., a Sempra Energy subsidy, plans to launch a pilot looking at delivering power to the grid from electric school buses. The six buses in the pilot transport students in El Cajon, Calif., east of San Diego.

“The buses are perfect because of their big batteries and predictable schedule,” Jessica Packard, SDG&E spokesperson, said in an email. “Ultimately, we hope to scale up and deploy these kinds of innovations throughout our grid in the future.”

She declined to say how much power the buses could deliver because the project isn’t yet operating. It’s set to start later this year.

Mobility needs
While BMW and PG&E did not review vehicle-to-grid power transfers in their own 2017 research ending last year, one study in Delaware did. But it was in a university setting about eight years ago and didn’t look at actual drivers, said Langton with BMW.

In their own findings from the San Francisco Bay Area pilot program, BMW and PG&E found that incentives could quickly change driver behavior in terms of charging.

Technology helps: Most new EVs have timers that allow the driver to control when to charge and when to stop charging. Langton said the pilot program got drivers to have their cars charge from roughly 2 to 6 a.m., when electricity rates typically are lowest.

There can be a lot of solar energy during the day, but in summer, optimum charging times get more complicated in California, he said. People want to run their air conditioners during peak heat hours, so it’s important to be able to get EV drivers to shift to less congested times, he said.

With the right incentives or messaging, Langton said, the pilot persuaded drivers to move charging from 10 a.m. to 2 p.m. or noon to 4 p.m. BMW technology allowed for detailed information on battery charge level, ideal charging times and other EV data to be transmitted electronically after plugging in.

The findings are a good first step toward future vehicle-to-grid integration, Langton added.

“One of the things we really pay attention to when we do smart charging is, ‘How does the driver’s mobility needs figure into shifting their charging?'” he said. “We want to make sure that our customers can always do the driving that they need to do.”

The pilot included safeguards such as an opt-out button if the driver wanted to charge immediately. It also made sure the vehicle had a certain level of minimum charge — 15% to 20% — before the delayed smart charging kicked in.

Vehicle-to-grid technology would need to wrestle with the same concepts in a different way. If a car is getting discharged, the driver would want assurances its battery wouldn’t dip below a level that meets their mobility needs, Langton said.

“If that happened even once to a customer, they would probably not want to participate in these programs in the future,” he said.

One group adding charging stations across the country said it isn’t tweaking pricing based on when drivers charge. That’s to help grow EV purchases, said Robert Barrosa, senior director of sales and marketing at Volkswagen AG subsidiary Electrify America, which operates about 450 charging stations in 45 states.

The company has installed battery storage at more than 100 sites to make sure they can provide power at consistent prices even if California or another state calls for energy conservation.

“It’s very important for vehicle adoption that the customer have that,” Barrosa said.

The company could sell that battery storage back to the grid if there are shortfalls, but some market changes are needed first, particularly in California, he said. That’s because the company buys electricity on the retail side but would be sending it back into the wholesale market.

With that cost differential, Barrosa said, “it doesn’t make sense.”

US Solar Power 2050 Target projects 45% electricity from solar, advancing decarbonization with clean energy, wind, nuclear, hydropower, hydrogen, and scalable energy storage, while modernizing the grid and transmission to cut emissions and create jobs.

Key Points

A goal for solar to supply ~45% of US electricity by 2050, backed by energy storage and other low-carbon generation.

✅ Requires 1,050-1,570 GW solar and matching storage capacity

✅ Utility-scale buildout uses ~10M acres; rooftop 10-20% of capacity

✅ Complemented by wind, nuclear, hydropower, hydrogen, and flexible turbines

President Joe Biden has called for major clean energy investments as a way to curb climate change and generate jobs. On Sept. 8, 2021, the White House released a report produced by the U.S. Department of Energy that found that solar power could generate up to 45% of the U.S. electricity supply by 2050, compared to less than 4% today, with about 3% in 2020 noted by industry observers. The Conversation asked Joshua D. Rhodes, an energy technology and policy researcher at the University of Texas at Austin, what it would take to meet this target.

Why such a heavy focus on solar power? Doesn’t a low-carbon future require many types of clean energy, even though wind and solar could meet about 80% of demand according to some research?
The Energy Department’s Solar Futures Study lays out three future pathways for the U.S. grid: business as usual; decarbonization, meaning a massive shift to low-carbon and carbon-free energy sources; and decarbonization with economy-wide electrification of activities that are powered now by fossil fuels.

It concludes that the latter two scenarios would require approximately 1,050-1,570 gigawatts of solar power, which would meet about 44%-45% of expected electricity demand in 2050, even as renewables approach one-fourth of U.S. generation in the near term. For perspective, one gigawatt of generating capacity is equivalent to about 3.1 million solar panels or 364 large-scale wind turbines.

The rest would come mostly from a mix of other low- or zero-carbon sources, including wind, nuclear, hydropower, biopower, geothermal and combustion turbines run on zero-carbon synthetic fuels such as hydrogen. Energy storage capacity – systems such as large installations of high-capacity batteries – would also expand at roughly the same rate as solar, with record growth in solar and storage anticipated by industry in coming years.

One advantage solar power has over many other low-carbon technologies is that most of the U.S. has lots of sunshine. Wind, hydropower and geothermal resources aren’t so evenly distributed: There are large zones where these resources are poor or nonexistent.

Relying more heavily on region-specific technologies would mean developing them extremely densely where they are most abundant. It also would require building more high-voltage transmission lines to move that energy over long distances, which could increase costs and draw opposition from landowners – a key reason the grid isn't yet 100% renewable according to experts – in many regions.

Is generating 45% of U.S. electricity from solar power by 2050 feasible?
I think it would be technically possible but not easy. It would require an accelerated and sustained deployment far larger than what the U.S. has achieved so far, even as the cost of solar panels has fallen dramatically, and wind, solar and batteries are 82% of the utility-scale pipeline across the country. Some regions have attained this rate of growth, albeit from low starting points and usually not for long periods.

The Solar Futures Study estimates that producing 45% of the nation’s electricity from solar power by 2050 would require deploying about 1,600 gigawatts of solar generation. That’s a 1,450% increase from the 103 gigawatts that are installed in the U.S. today, even as wind and solar trend toward 30% of U.S. electricity in some outlooks. For perspective, there are currently about 1,200 gigawatts of electricity generation capacity of all types on the U.S. power grid.

The report assumes that 10%-20% of this new solar capacity would be deployed on homes and businesses. The rest would be large utility-scale deployments, mostly solar panels, plus some large-scale solar thermal systems that use mirrors to reflect the sun to a central tower.

Assuming that utility-scale solar power requires roughly 8 acres per megawatt, this expansion would require approximately 10.2 million to 11.5 million acres. That’s an area roughly as big as Massachusetts and New Jersey combined, although it’s less than 0.5% of total U.S. land mass.

I think goals like these are worth setting, but are good to reevaluate over time to make sure they represent the most prudent path.

EV Boom Aftershock highlights electric vehicles straining grid capacity as policy accelerates adoption, requiring charging infrastructure, renewable energy storage, and transition models from Tesla, NIO, Toyota, GM, Blink Charging, and Facedrive's Steer subscription.

Key Points

EV Boom Aftershock is the grid and industry strain from rapid EV adoption requiring charging and storage upgrades.

✅ Policy push: fleet electrification, 550k chargers planned

✅ Grid capacity, storage, and charging infrastructure are critical

✅ Bridge models: subscriptions, rideshare, and logistics electrification

2020 ushered in the start of the EV boom, but it could have a frightening aftershock. The world is already seeing some of the incredible triple-digit gains in EV companies like Tesla and Workhorse. And this EV wave is only expected to grow bigger in the days ahead under the Biden administration.  Mentioned in today's commentary includes:  Tesla, Inc., NIO Limited, Toyota Motor Corporation, General Motors Company, Blink Charging Co.

Just a week after inauguration, President Biden reported he plans to replace the entire government fleet with electric vehicles. That's up to 643,000 vehicles turning electric on the government's dime. But Toyota's president, Akio Toyoda, had an ominous prediction for what could lie ahead.

He stated that if EVs are adopted too quickly, we may not have the energy to support them at this point. In fact, he predicted Japan would run out of electricity by summer if they banned all gas-powered vehicles now. He even went as far as to say that if we rush the process of transitioning to EVs all at once, "the current business model of the auto industry is going to collapse."

While the buzz for electric vehicles has only grown over the last year, many often miss this key piece in making such a drastic shift in such a short period. And although it's expected to create plenty of demand for solar, wind, nuclear, and geothermal energy sources…

At this point in the game, they are still too expensive and lack the storage capacity we'd need for those to be the final solution. That's why companies bridging the gap to the EV world are thriving.

Facedrive, a company known for its "people and planet first" approach, has seen incredible success over the last year, for example. They recently acquired EV subscription company, Steer, from the largest clean energy producer in the United States. Steer's subscription model for EV cars is putting a major twist on the traditional car ownership model. So instead of everyone going out and buying their own EV, they can borrow one as-needed instead.

With Facedrive's acquisition of Steer, customers pay a simple monthly fee like with Netflix, and they get access to a fleet of EVs at their disposal.

Over the last year, big moves like this have helped Facedrive sign a number of important partnerships and deals including government agencies, A-list celebrities, and major multinational corporations. And they've even managed to grow their business throughout the United States and Canada during a time when ridesharing as an industry suffered during global lockdowns.

Smartest in the World Making Bold Predictions

While Toyota's president made a dark prediction about where we could be headed, he's not alone in being concerned. Elon Musk expressed his own concerns about the issue recently as well.

In an interview in December, he said that the world's electricity consumption would likely double once EVs become the norm. And that's only accounting for this mass adoption in electric vehicles.

The situation could become even more pressing as the rest of our lives grow increasingly digital too, sucking up more electricity in the process. With the "internet of things" creating smart cities and smart homes, the demand for electricity will only go up as everything from Peloton bikes to Nest thermostats are now connected by the internet.

With thousands of cars on the roads during morning and evening commutes, it's not hard to imagine times where we simply wouldn't have enough grid capacity to charge all EVs that need it at once.

But in the meantime, Facedrive's moves are putting them squarely in position to smooth out the transition. And in addition to the monthly membership model used with Steer, they're helping keep the number of cars on the road down through their signature ridesharing service.

Their model is simple. When customers hail a ride, they have the choice to ride in an electric vehicle or a standard gas-powered car. After they get to their destination, the Facedrive algorithm sets aside a portion of the fare to plant trees, offsetting the carbon footprint from the ride. In other words, customers ride, they plant a tree.

Through next-gen technology and partnerships, they're giving their customers the option to make a more eco-friendly choice if they choose. Plus, Facedrive has added a booming food delivery service, which has expanded at a record pace while folks were stuck at home during global lockdowns.

They're now delivering over 4,100 orders per day on average. And after growing to 19 major cities, they plan to expand to more cities throughout the U.S. and Canada soon. It's this kind of innovative thinking that has many so optimistic about the opportunities that lie ahead.

Who Will Win In The EV Boom?

Elon Musk warned that, like with the boom in smartphones, we're not likely to see the EV revolution all happen at once, and industry leaders still see mainstream hurdles ahead for broad adoption. Because just like with smartphones, you can't replace them all at once. But it's undeniable that the movement is growing at a remarkable pace, with many arguing it has reached an inflection point already in several segments today.

Even under an administration that was not supportive of climate change and green initiatives, the EV markets have soared throughout 2020, and U.S. EV sales are surging into 2024 as well across segments.

Tesla was one of the biggest market stories of the year, locking in over 700% gains on its way to becoming one of the largest companies on the S&P 500. And experts are expecting to see massive spending on the infrastructure needed for EVs under the Biden administration too.

In addition to his vow to spend more on clean energy research, President Biden also reported plans to build out 550,000 EV charging stations across the country. With the growth we've seen in this area already, it's also caused shares for companies like Plug Power to soar over 1,000% in 2020. And Facedrive has been sharing in this success too, with incredible gains of 834% over the last year.

Facedrive hasn't been the only company riding the EV wave, however.  Tesla (TSLA) was among the biggest market stories of 2020 with incredible gains of over 700%. This helped them become one of the highest-valued stocks in the United States with other Big Tech giants. It is now the most valuable car maker "of all time". It is now worth almost $800 billion.

After a much-touted Battery Day event and expectations of Musk developing a "Million Mile Battery" in the near future, Tesla recently joined the S&P 500.

Billionaire Elon Musk had his eye on this trend far before the hype started building. He released the first Tesla Roadster back in 2008, making electric vehicles cool when people were still snubbing their noses at the first-generation EVs. Since then, Tesla's stock has skyrocketed by over 14,000%. But while Tesla's EV threat to the industry is clear, the competition is heating up in China's EV market right now as rivals scale.

Nio (NIO) is Tesla's biggest competitor, dominating the Chinese EV markets. After going public in 2018, it's been on a tear, producing vehicles with record-breaking range. They recently unveiled their first electric sedan with a longer range battery, which sent shares surging in early January.

Nio's current performance is a far cry from just one year ago In fact, many shareholders were ready to write off their losses and give up on the company. But China's answer to Tesla's dominance powered on, eclipsed estimates, and most importantly, kept its balance sheet in line. And it's paid off. In a big way. The company has seen its share price soar from $3.24 at the start of 2020 to a high of $61 this month, representing a massive 1600% returns for investors who held strong. 

By NIO's fourth quarter report in October, the company announced that its sales had more-than doubled, projecting even greater sales in 2021. The EV up-and-comer has shocked investors and pulled itself back after its rumored potential bankruptcy in 2019, and if this year shows investors anything, it's that its CEO William Li is as skilled and ambitious as anyone in the business.

Toyota Motors (TM) is a massive international car producer who hasn't ignored the transition to greener transportation. In fact, the Toyota Prius was one of the first hybrids to hit the road in a big way. While the legacy hybrid vehicle has been the butt of many jokes throughout the years, the car has been a major success, and more importantly, it helped spur the adoption of greener vehicles for years to come.

And just because its Prius hasn't exactly aged as well as some green competitors, Toyota hasn't left the green power race yet. Just a few days ago, actually, the giant automaker announced that three new electric vehicles will be coming to United States markets soon.

Toyota has a major hold over U.S. markets at the moment. In fact, it maintains a 75% share of total fuel cell vehicles and a 64% share in hybrid and plug-in vehicles. And now it's looking to capture a greater share of electric vehicles, as well.

General Motors (GM) is one of the legacy automakers benefiting from a shift from gas-powered to EV technology. Even with the downfall of Detroit, GM has persisted, and that's due in large part to its ability to adapt. In fact, GM's dive into alternative fuels began way back in 1966 when it produced the world's first ever hydrogen-powered van for testing. And it has not stopped innovating, either.

With the news of GM's new business unit, BrightDrop, they plan to sell electric vans and services to commercial delivery companies, disrupting the market for delivery logistics. This is a huge move as delivery sales have absolutely exploded during the COVID-19 pandemic, and are projected to grow even further over the coming years.

And in January 2021, the giant automaker announced that it will discontinue production of all gas-powered vehicles, including hybrids, by 2035. This is a key factor in its commitment to become carbon-net zero by 2040.  The move will likely sit well with shareholders which are increasingly pushing for companies to clean up their act.

Blink Charging (BLNK) is building an EV charging network that may be small right now, but it's got explosive growth potential that is as big as the EV market itself. This stock is on a major tear and all that cash flowing into it right now gives Blink the superpower to acquire and expand. 

A wave of new deals, including a collaboration with EnerSys and another with Envoy Technologies to deploy electric vehicles and charging stations adds further support to the bullish case for Blink.

Michael D. Farkas, Founder, CEO and Executive Chairman of Blink noted, "This is an exciting collaboration with EnerSys because it combines the industry-leading technologies of our two companies to provide user-friendly, high powered, next-generation charging alternatives. We are continuously innovating our product offerings to provide more efficient and convenient charging options to the growing community of EV drivers."

US Plug-in EV Miles 2021 highlight BEV and PHEV growth, DOE and Argonne data, 19.1 billion electric miles, 6.1 TWh consumed, gasoline savings, rising market share, and battery capacity deployed across the US light-duty fleet.

Key Points

They represent 19.1 billion electric miles by US BEVs and PHEVs in 2021, consuming 6.1 TWh of electricity.

✅ 700 million gallons gasoline avoided in 2021

✅ $1.3 billion fuel cost savings estimated

✅ Cumulative 68 billion EV miles since 2010

Plug-in electric cars are gradually increasing their market share in the US (reaching about 4% in 2021), which starts to make an impact even as the U.S. EV market share saw a brief dip in Q1 2024.

The Department of Energy (DOE)’s Vehicle Technologies Office highlights in its latest weekly report that in 2021, plug-ins traveled some 19.1 billion miles (31 billion km) on electricity - all miles traveled in BEVs and the EV mode portion of miles traveled in PHEVs, underscoring grid impacts that could challenge state power grids as adoption grows.

This estimated distance of 19 billion miles is noticeably higher than in 2020 (nearly 13 billion miles), which indicates how quickly the electrification of driving progresses, with U.S. EV sales continuing to soar into 2024. BEVs noted a 57% year-over-year increase in EV miles, while PHEVs by 24% last year (mostly proportionally to sales increase).

According to Argonne National Laboratory's Assessment of Light-Duty Plug-in Electric Vehicles in the United States, 2010–2021, the cumulative distance covered by plug-in electric cars in the US (through December 2021) amounted to 68 billion miles (109 billion miles).

U.S. Department of Transportation, Federal Highway Administration, December 2021 Traffic Volume Trends, 2022.

The report estimates that over 2.1 million plug-in electric cars have been sold in the US through December 2021 (about 1.3 million all-electric and 0.8 million plug-in hybrids), equipped with a total of more than 110 GWh of batteries, even as EV sales remain behind gas cars in overall market share.

It's also estimated that 19.1 billion electric miles traveled in 2021 reduced the national gasoline consumption by 700 million gallons of gasoline or 0.54%.

On the other hand, plug-ins consumed some 6.1 terawatt-hours of electricity (6.1 TWh is 6,100 GWh), which sounds like almost 320 Wh/mile (200 Wh/km), aligning with projections that EVs could drive a rise in U.S. electricity demand over time.

The difference between the fuel cost and energy cost in 2021 is estimated at $1.3 billion, with Consumer Reports findings further supporting the total cost advantages.

Cumulatively, 68 billion electric miles since 2010 is worth about 2.5 billion gallons of gasoline. So, the cumulative savings already is several billion dollars.

Those are pretty amazing numbers and let's just imagine that electric cars are just starting to sell in high volume, a trend that mirrors global market growth seen over the past decade. Every year those numbers will be improving, thus tremendously changing the world that we know today.

Texas Battery Storage Investment Boom draws BlackRock, SK, and UBS, leveraging ERCOT price volatility, renewable energy growth, and utility-scale energy storage arbitrage to enhance grid reliability, resilience, and double-digit returns across high-demand nodes.

Key Points

Texas sees a rush into battery storage, using ERCOT price spreads to bolster grid reliability and earn about 20% returns.

✅ Investors exploit price volatility, peak-demand spreads.

✅ Utility-scale storage enhances ERCOT reliability.

✅ Top players: BlackRock, SK E&S, UBS; 700 MW deals.

BlackRock, Korea's SK, Switzerland's UBS and other companies are chasing an investment boom in battery storage plants in Texas, lured by the prospect of earning double-digit returns from the power grid problems plaguing the state, according to project owners, developers and suppliers.

Projects coming online are generating returns of around 20%, compared with single digit returns for solar and wind projects, according to Rhett Bennett, CEO of Black Mountain Energy Storage, one of the top developers in the state.

"Resolving grid issues with utility-scale energy storage is probably the hottest thing out there,” he said.

The rapid expansion of battery storage could help, through efforts like a virtual power plant initiative in Texas, prevent a repeat of the February 2021 ice storm and grid collapse which killed 246 people and left millions of Texans without power for days.

The battery rush also puts the Republican-controlled state at the forefront of President Joe Biden's push to expand renewable energy use.

Power prices in Texas can swing from highs of about $90 per megawatt hour (MWh) on a normal summer day to nearly $3,000 per MWh when demand surges on a day with less wind power, a dynamic tied to wind curtailment on the Texas grid according to a simulation by the federal government's U.S. Energy Information Administration.

That volatility, a product of demand and higher reliance on intermittent wind and solar energy, has fueled a rush to install battery plants, aided by falling battery costs, that store electricity when it is cheap and abundant and sell when supplies tighten and prices soar.

Texas last year accounted for 31% of new U.S. grid-scale energy storage, with much of it pairing storage with solar, according to energy research firm Wood Mackenzie, second only to California which has had a state mandate for battery development for a decade.

And Texas is expected to account for nearly a quarter of the U.S. grid-scale storage market over the next five years, a trajectory consistent with record U.S. solar-plus-storage growth noted by analysts, according to Wood Mackenzie projections shared with Reuters.

Developers and energy traders said locations offering the highest returns -- in strapped areas of the grid -- will become increasingly scarce as more storage comes online and, as diversifying resources for better projects suggests, electricity prices stabilize.

Texas lawmakers this week voted to provide new subsidies for natural gas power plants in a bid to shore up reliability. But the legislation also contains provisions that industry groups said could encourage investment in battery storage by supporting 'unlayering' peak demand approaches.

Amid the battery rush, BlackRock acquired developer Jupiter Power from private equity firm EnCap Investments late last year. Korea's SK E&S acquired Key Capture Energy from Vision Ridge Partners in 2021 and UBS bought five Texas projects from Black Mountain last year for a combined 700 megawatts (MW) of energy storage. None of the sales' prices were disclosed.

SK E&S said its acquisition of Key Capture was part of a strategy to invest in U.S. grid resiliency.

"SK E&S views energy storage solutions in Texas and across the U.S. as a core technology that supports a new energy infrastructure system to ensure American homes and businesses have affordable power," the company said in a statement.

Wind farm reliability services now compete in wholesale markets, as FERC and NERC endorse market-based solutions that reward performance, bolster grid resilience, and compensate ancillary services like frequency regulation, voltage support, and spinning reserve.

Key Points

Grid support from wind plants, including frequency, voltage, ramping, and inertial response via advanced controls.

✅ Enabled by advanced controls and inverter-based technology

✅ Compete in market-based mechanisms for ancillary services

✅ Support frequency, voltage, reserves; enhance grid resilience

American Wind Energy Association CEO Tom Kiernan has explained to a congressional testimony that wind farms can now compete, as renewables approach market majority, to provide essential electric reliability services. 

Mr Kiernan appeared before the US Congress House Energy and Commerce Committee where he said that, thanks to technological advances, wind farms are now competitive with other energy technologies with regard to reliability and resiliency. He added that grid reliability and resilience are goals that everyone can support and that efforts underway at the Federal Energy Regulatory Commission (FERC) and by market operators are rightly focused on market-based solutions to better compensate generators for providing those essential services.

AWEA strongly agreed with other witnesses on the panel who endorsed market-based solutions in their submitted testimony, including the American Petroleum Institute, Solar Energy Industries Association, Energy Storage Association, Natural Resources Defence Council, National Hydropower Association, and others. However, AWEA is concerned that the Department of Energy’s recent proposal to provide payments to specific resources based on arbitrary requirements is anti-competitive, and threatens to undermine electricity markets that are bolstering reliability and saving consumers billions of dollars per year.

“We support the objective of maintaining a reliable and resilient grid which is best achieved through free and open markets, with a focus on needed reliability services – not sources – and a programme to promote transmission infrastructure.”

Kiernan outlined several major policy recommendations in his testimony, including reliance on competitive markets that reward performance to ensure affordable and reliable electricity, a focus on reliability needs rather than generation sources and the promotion of transmission infrastructure investment to improve resilience and allow consumers greater access to all low-cost forms of energy.

The CEO of the North American Electric Reliability Corporation (NERC) has recently testified that the state of reliability in North America remains strong and the trend line shows continuing improvement year over year. Technological advances and innovation by over 100,000 US wind workers enable wind farms today to provide the grid reliability services traditionally provided by conventional power plants. NERC’s CEO emphasised in its testimony at last month’s hearing that “variable resources significantly diversify the generation portfolio and can contribute to reliability and resilience in important ways.”
