The Storage Futures Study (SFS) was launched in 2020 by the National Renewable Energy Laboratory and is supported by the U.S. Department of Energy’s (DOE’s) Energy Storage Grand Challenge. The study explores how energy storage technology advancement could impact the deployment of utility-scale storage and adoption of distributed storage, as well as future power system infrastructure investment and operations.

There is economic potential for up to 490 gigawatts per hour of behind-the-meter battery storage in the United States by 2050 in residential, commercial, and industrial sectors, or 300 times today’s installed capacity. But only a small fraction could be adopted by customers, according to the latest phase of the National Renewable Energy Laboratory’s (NREL’s) Storage Futures Study.

“By implementing new battery capabilities in our model, we were able to do scenario comparison that revealed battery cost and the value of backup power are important drivers of distributed storage deployment,” said Ashreeta Prasanna, lead author of the NREL technical report, Distributed Solar and Storage Outlook: Methodology and Scenarios.

The study provides one of the first published estimates of distributed battery storage deployment. The NREL team of analysts — also including Kevin McCabe, Ben Sigrin, and Nate Blair — modeled customer adoption of battery storage systems coupled with solar photovoltaics (PV) in the United States out to 2050 under several scenarios. The results can help inform planning for technical grid infrastructure to capture the benefits and mitigate the challenges of growing distributed electricity generation.

PV-Plus-Battery Scenarios

The Rise of Behind-the-Meter Battery Storage

A widespread transition to distributed energy resources (DERs) is taking place. Households and businesses around the world are adopting DERs to lower their energy bills and curb carbon emissions. Local policymakers have set ambitious energy and climate goals; grid resiliency is a growing concern due to climate change and weather disasters; and more communities face high energy burdens.

In addition, Federal Energy Regulatory Commission Order 2222 enables DERs to participate alongside traditional energy resources in regional organized wholesale markets.

All these factors have contributed to a rise in DER deployment, including batteries. With declining battery storage costs, customers are starting to pair batteries with distributed solar. Behind-the-meter battery capacity totaled almost 1 gigawatt in the United States by the end of 2020, according to Wood Mackenzie.

While DERs offer many benefits to customers and the grid, like peak load shifting, integrating these resources into the power system presents complex challenges for electric utilities. “The transmission system wasn’t designed with distributed generation in mind,” said Ben Sigrin, coauthor of the report. “Projected DER adoption potential can provide a window into distributed generation and help inform future power system planning.”

Bottom-up Modeling for Bottom-up Generation

NREL’s open-source Distributed Generation Market Demand (dGen) model simulates customer adoption of distributed solar, wind, and storage using a bottom-up, agent-based approach and spatially resolved data (watch a Super Mario Bros.-inspired video to learn more).

For this phase of the Storage Futures Study, the model was modified to simulate the technical, economic, and market potential of behind-the-meter battery storage.

dGen interoperated with NREL’s System Advisor Model (SAM), which simulates the performance and efficiency of energy technologies, including cash flow analysis to calculate payback periods — an important consideration in a customer’s decision to adopt a technology.

By interfacing with SAM, dGen modeled the cost-effectiveness and customer adoption of PV-plus-battery storage systems for residential, commercial, and industrial entities in the United States with different technology costs, storage valuation, incentives, and compensation. The resulting upper and lower bounds of adoption revealed what customers consider most in their decisions.

Lower Battery Costs, High Backup-Power Value Drives Deployment

Across all 2050 scenarios, dGen modeled significant economic potential for distributed battery storage coupled with PV. Scenarios assuming modest projected declines in battery costs and lower value of backup power show economic potential for 114 gigawatts of storage capacity — a 90-times increase from today. When battery costs significantly reduce and the value of backup power doubles, the economic potential increases to 245 gigawatts.

However, only 7% of the estimated capacity is adopted by customers. The difference is largely due to the long payback period for distributed PV-plus-battery storage systems, which averages 11 years for the residential sector, 12 years for the commercial sector, and 8 years for the industrial sector in 2030.

“The estimated adoption potential translates to less than 20% of the market potential,” Prasanna said. “Customers are less inclined to invest in a system that takes a long time to be profitable.”

Modeled deployment varies by location based on specific rate structures or incentive programs but is generally driven by battery cost and the value of backup power. Similar trends are seen on the national scale, where lower battery costs and high backup-power value increase deployment.

PV and Batteries Drive Each Other’s Adoption

Several findings in the study demonstrate that PV and batteries make an economical pairing. Because an average PV-plus-battery storage system is larger than PV-only configurations, battery storage increases the PV capacity and the system’s economic value.

About 34%–40% of total annual PV installations projected in 2050 in the reference or baseline scenario are coadopted with batteries. This rate, again, is driven by higher value of backup power and lower technology costs.

Combined cost reductions in both PV and battery storage technologies drive additional adoption compared to cost reductions in just battery technology alone. When costs decrease for both technologies, more customers adopt PV-plus-battery systems, and deployment increases by 106% in 2050.

“The process of developing and implementing the distributed storage technology within dGen revealed additional questions and needed research capabilities related to behind-the-meter battery storage adoption,” Prasanna said. “Additional enhancements of dGen will be needed to explore research questions such as projecting the adoption of community-scale DERs and storage capacity and their impact on the distribution grid, exploration of the tradeoffs between distributed and utility-scale storage, and the role of DERs in supporting the transition to a decarbonized economy.”

Is the Honda Prologue the best EV to lease right now?

The Honda Prologue continues to surprise, ranking among the top ten most leased vehicles (gas-powered or EV) in the US in the first quarter. It was the only EV, outside of Tesla’s Model Y and Model 3, that made the list.

Honda Prologue EV is one of the most leased vehicles

After launching the Prologue in the US last March, Honda’s electric SUV took off. In the second half of the year, it was the second-best-selling electric SUV, trailing only the Tesla Model Y.

The Prologue remains a top-selling EV in the US this year, with over 13,500 units sold through May. That’s not too bad, considering it only sold 705 through May of last year.

According to a new Experian report (via Automotive News), Honda’s success is being driven by ultra-affordable lease rates. In the first quarter, nearly 60% of new EV buyers in the US chose to lease, up from just 36% a year ago.

Three EVs ranked in the top ten most leased vehicles in Q1, including the Tesla Model Y, Model 3, and Honda Prologue.

Tesla’s Model Y and Model 3 took the top two spots, while the Honda Prologue ranked number seven. Those who leased Tesla’s Model 3 paid $402 per month, Honda Prologue lessees paid $486 a month.

Given the average loan rate was $708 a month for those who bought it, it’s no wonder nearly 90% chose to lease. Under 9% chose to buy, while less than 2% paid cash.

The discounts are piling up, but for how long?

To give you a better idea, the average monthly payment for a new vehicle lease in the US in the first quarter was $595.

With over $20,000 in discounts, Honda’s luxury Acura brand is selling a surprising number of EVs in the US. The nearly $65,000 Acura ZDX is sold for under $40,000 on average in May, according to Cox Automotive’s EV Market Monitor report for May.

The trend is primarily thanks to the $7,500 federal EV tax credit, which is being passed on to customers through leasing.

With the Trump administration and Senate Republicans aiming to kill off federal subsidies, the savings could soon disappear. If the Senate’s recently proposed bill is passed, the $7,500 credit would expire within 180 days. It would not only make electric vehicles more expensive, but it would also put the US further behind China and others leading the shift to electrification.

Some automakers, including GM, are expected to continue offering the incentives. “GM has been very competitive on the incentives on their end, and that is not scheduled to end.”

After outselling Ford, GM’s Chevy is now the fastest-growing EV brand in the US through May. Chevy is starting to chip away at Tesla’s lead, largely thanks to the new Equinox EV, or “America’s most affordable +315 range EV,” as GM calls it.

According to Xperian, those who leased a new Chevy Equinox EV in Q1 paid $243 less than those who financed it. The electric Equinox stood out in Cox Automotive’s EV Market Monitor report with an average selling price under $40,000, even without incentives.

The Chevy Equinox EV remains one of the most affordable EVs on the market. Starting at just $34,995, the base LT FWD model offers an EPA-estimated range of 319 miles.

After Hyundai cut lease prices earlier this month, the 2025 IONIQ 5 might just take the cake. You can now lease the 2025 Hyundai IONIQ 5 (now with a built-in NACS port) for as low as $179 per month.

Looking to test out some of the most popular EVs for yourself? With Honda Prologue leases as low as $259 per month and Chevy Equinox EV leases starting at just $289 per month, the deals are hard to pass up right now while the incentives are still here.

US energy storage set a new record in Q1 2025 but the future looks shaky

US energy storage set a new record in Q1 2025 but the future looks shaky

The US energy storage market just posted its strongest Q1 ever, adding more than 2 gigawatts (GW) of capacity across all segments, according to the latest US Energy Storage Monitor from Wood Mackenzie and the American Clean Power Association (ACP).

That makes Q1 2025 the biggest first quarter for energy storage in US history.

The surge was led by utility-scale projects, which accounted for over 1.5 GW of the new capacity, a 57% jump compared to Q1 2024.

Surging energy demand is putting the electric grid under strain,” said John Hensley, SVP of markets and policy analysis at ACP. “The energy storage market is responding to help keep the lights on and support this unprecedented growth in an affordable and reliable way.”

But that momentum is now bumping up against policy uncertainty that could derail growth in the near future.

Indiana shows what’s possible

Energy storage is no longer limited to early-adopter states like California and Texas. In Q1, Indiana added 256 megawatts (MW) of new energy storage, quadrupling its total installed capacity. It now has more than 10 GW of new storage in its interconnection queue, the fifth-largest in the country.

Indiana’s growth is being driven by available land and clear permitting processes, two major barriers in other states.

“We’re now seeing significant deployment in emerging markets like Indiana, while states across the Southwest like Nevada and Arizona continue to expand their energy storage portfolio,” said Noah Roberts, VP of Energy Storage at ACP.

Home battery boom

Residential storage also set a new record, with 458 MW installed in Q1, the most ever in a single quarter. California and Puerto Rico led the way, accounting for 74% of that growth, while Illinois and other emerging markets began to pick up pace.

Trouble on the horizon

Despite a strong near-term outlook, the long-term picture is cloudier. The five-year forecast for utility-scale storage remains solid, but looming changes to federal policy could slash future growth.

If proposed changes to the Investment Tax Credit (ITC) in the House’s reconciliation bill become law, the total storage buildout over five years could fall 27% below the current base case.

  • Distributed storage would take the biggest hit, with a projected 46% drop.
  • Utility-scale storage could shrink by 16 GW.

The CCI (community, commercial, and industrial) segment has already seen a 42% cut in its five-year outlook, weighed down by tariff risks and slow adoption of California’s NEM 3.0 rules.

The Q1 2025 results demonstrate the demand for energy storage in the US to serve a grid with both growing renewables and growing load,” said Allison Weis, global head of energy storage at Wood Mackenzie. “However, the industry stands at a crossroads, with potential policy changes threatening to disrupt this momentum.”

In the near term, the report expects 15 GW/49 GWh of new storage capacity to be installed across all segments in 2025, with utility-scale installations projected to grow 22% year-over-year. However, the utility-scale segment is at risk for a potential 29% contraction in 2026 due to policy uncertainty.

Bottom line: the energy storage boom isn’t slowing down – yet. But all eyes are on Congress.

Cadillac just delivered the first Celestiq, a hand-built ultra-luxury EV that costs 0,000

The Celestiq is more than an ultra-luxury electric sedan. Cadillac is saying it “marks a new milestone in American luxury and innovation.” The ultra-luxury EV is hand-built at Cadillac House at Vanderbilt, but it’s not cheap. Cadillac’s flagship electric sedan starts at around $350,000.

Cadillac delivers the first ultra-luxury Celestiq EV models

Cadillac is back and better than ever. After delivering the first Celestiq models to customers on Tuesday, Cadillac said it’s out to re-establish the brand as the “Standard of the World.”

The ultra-luxury electric sedan was delivered during a private event at GM’s Global Tech Center in Warren, Michigan.

Each Celestiq model is hand-built at Cadillac House at Vanderbilt, where you can customize the vehicle through a “highly personalized experience.” Cadillac designers and engineers wanted to create the most technologically advanced vehicle possible.

Although the Celestiq was first unveiled in 2022 and was expected to go into production in 2023, the ultra-luxury EV arrives with a slight increase in power.

The electric sedan features a dual-motor AWD powertrain, packing 655 horsepower and 646 lb-ft of torque (with Velocity Max), good for a 0 to 60 mph sprint in 3.7 seconds. Powered by a massive 111 kWh battery, Cadillac says its flagship EV has a range of 303 miles.

Inside, you’ll find ample screen space with a 55″ advanced interactive display that spans the entire dashboard. It’s Cadillac’s first vehicle to feature five standard HD interactive displays, including two 12.6″ entertainment screens for rear passengers.

Other interior features include a panoramic Smart Glass Roof with four independently controlled sections, a 38-speaker AKG audio system, and Climatesense, a “world first” four-zone microclimate system.

Each Celestiq is built to order and assembled at GM’s new Artisan Center on its campus in Warren, Michigan. Prices start in the “mid-$300,000 range.” You can inquire for more information on Cadillac’s website.

Electrek’s Take

Cadillac is coming off one of its best sales quarters since 2008. With a full lineup of electric SUVs, Cadillac is aiming to be the bestselling luxury EV brand in the US this year.

With the entry-level Optiq, midsize Lyriq, three-row Vistiq, and massive Escalade IQ, Cadillac offers an EV in nearly every segment.

Earlier this week, GM announced that the 2026 Cadillac Optiq will be its first vehicle to launch with a built-in NACS port, allowing it to access Tesla’s Supercharger network.

Although Cadillac said the Celestiq would help re-establish the brand as the “Standard of the World,” it will likely play only a minor role. The Optiq, Lyriq, Vistiq, and Escalade IQ will be the growth drivers over the next few years in a competitive luxury EV market.

GM said over 75% of Optiq buyers were new to Cadillac last month. After delivering the first models in late 2024, Cadillac sold over 1,700 Optiqs in the first quarter, outpacing Mercedes-Benz, Genesis, and other luxury rivals in the US.
