U.S. grid-scale energy storage hit another record high for third-quarter installations as growth in renewable energy elevated storage needs to boost the reliability of electric grids.
The latest U.S. Energy Storage and Monitor, a joint report of the American Clean Power Association (ACP) and Wood Mackenzie, show grid-scale energy storage installations hit a record 3.43 gigawatts (GW) for third-quarter 2024, a more than 80% jump compared to a year earlier.
“We are seeing the energy storage industry fill a real need across the country to provide reliability in an affordable and efficient manner for communities,” John Hensley, senior vice president of markets and policy analysis for ACP, said in a Dec. 12 news release. “With 64 GW of new energy storage expected in the next four years, the market signal continues to be clear that energy storage is a critical component of the grid moving forward.”
The increase came as power needs climb with more growth expected driven by data centers and manufacturing operations.
Installations in Texas skyrocketed to nearly 1.7 GW for third-quarter 2024, compared to the previous quarter, ACP said in the release. Looking at gigawatt hours (GWh) of installations, California topped other states with about 6 GWh added.
The residential segment also reported a record-setting 346 megawatts (MW) installed. That was a 63% increase compared with the last quarter.
“The grid-scale and residential segments will continue to lead the market, with grid-scale installations projected to more than double by 2028 to reach a cumulative volume of 63.7 GW, and residential installing 10 GW of storage in the same time period,” ACP said.
Tax credits, such as the Section 48 investment tax credit that was expanded under Inflation Reduction Act, have helped accelerate energy storage growth. The credit offers companies a 30% base tax credit if certain apprenticeship and wage requirements are met.
However, with a new administration set to take office, there is some uncertainty about the future of tax credits and how higher tariffs could impact the pace of growth.
“While there might be potential opportunities in a new pricing environment for domestic manufacturers in terms of competition, any major shifts in tax incentives or increased tariffs could outweigh benefits and have an impact on new project development,” said Allison Weis, global head of storage for Wood Mackenzie.

Drax, Pathway Energy Enter Deal for Biomass Pellets for SAF Project
U.K.-based Drax Group on Dec. 12 said it will supply Pathway Energy with more than 1 million tonnes of sustainable biomass pellets annually for Pathway’s proposed sustainable aviation fuel (SAF) facility on the U.S. Gulf Coast.
Located in Port Arthur, Texas, the $2 billion facility is expected to produce 30 million gallons of SAF per year, the equivalent of fueling for 5,000 long-haul flights per year, according to a news release.
The agreement between Drax and Pathway came as the aviation sector works to lower emissions by using sustainable fuels. SAF can lower carbon emission by up to 80% compared to traditional jet fuels, Drax said in the news release.
Pathway plans to begin constructing the facility in early 2026 with commercial SAF production beginning in 2029.
“This landmark deal has the potential to be the biggest third-party supply arrangement Drax’s pellet business has made,” said Drax Group CEO Will Gardiner. Demand for sustainable biomass is accelerating, with international businesses seeking long-term fuel supplies for a range of projects globally – including sustainable aviation fuel and bioenergy with carbon capture and storage.
In addition, Drax said it could become a partner in the project and potentially invest up to $10 million in the form of a convertible loan note.

Energy Vault, RackScale Partner to Scale Up Data Centers by 2 GW
RackScale Data Centers has teamed up with Energy Vault Holdings for 2 GW of power for data centers, the energy storage company said Dec. 11.
Plans are to utilize Energy Vault’s multi-story B-Nest hyperscale battery energy storage systems at data center sites developed by RackScale. Construction at data sites is scheduled to begin in 2026.
The partnership emerged as hyperscalers continue to lock in electricity, including from renewables and energy storage systems, to meet growing power needs. The surge in demand is driven in part by the computational power needs of artificial intelligence systems. Data center power demand is expected to surge by 160% by 2030, according to Goldman Sachs Research estimates.
“With the rapid increase in power demand from the rise of the data center sector, it is absolutely essential that renewable energy generation and storage become key points of focus to power the AI data center boom,” said Marco Terruzzin, chief commercial and product officer for Energy Vault.
The company said its B-Nest system is capable of storing up to 1.6 GWh of energy per acre, and the system’s ultra-high energy density enables it to provide each data center with full primary power for more than 10 hours.
“The B-Nest system’s high energy density and advanced safety design are game-changers for our operations, enabling us to accelerate firm grid power interconnections and onsite generation to meet the needs of our data center sites,” RackScale Data Centers CEO Trent D’Ambrosio said.

EU Looks to Geothermal in Drive for Energy Security, Document Shows
EU countries plan to promote geothermal energy as they hunt for ways to replace Russian gas and bring down energy prices, a draft EU document showed.
The 27 EU members will jointly endorse geothermal energy for the first time at a meeting of EU energy ministers in Brussels next week, according to a draft document seen by Reuters, and will ask the European Commission to come up with a bloc-wide plan to get projects off the ground.
The draft requests an EU strategy to reduce emissions from heating and cooling systems, and specific EU measures to speed up geothermal projects. Ministers will suggest this includes financial guarantees to de-risk investments and simpler permitting rules, the document showed.
Geothermal projects drill underground to access local subterranean heat, which is brought to the surface to provide a constant source of heating to buildings, or to generate electricity.
“The use of geothermal energy contributes to the strategic objectives of the European Union by decreasing energy dependence and fossil fuel imports,” the draft document said.
High energy prices for industries and households, and the loss of most Russian gas since Moscow’s 2022 invasion of Ukraine, have prompted European countries to speed up their expansion of renewable energy.
But while wind and solar capacity have jumped, geothermal energy—another renewable source which the EU hopes can help replace fossil fuels—remains much smaller. Projects still struggle with high upfront investment costs and complex regulations.
EU data show geothermal produced less than 3% of the bloc’s energy in 2022. That’s despite it having the potential to cover three-quarters of EU heating and cooling needs in residential and commercial buildings by 2040, according to industry group the European Geothermal Energy Council.
Most EU countries already have geothermal district heating systems, but only a handful—including France, Germany and Italy—use it to generate electricity.

Germany Awards 4,098 MW Onshore Wind Power Capacity in Latest Auction
Germany’s network regulator on Dec. 11 said it approved 4,098 MW of new onshore wind power capacity in a quarterly auction held on Nov. 1, which was 1.5 times oversubscribed.
The Bundesnetzagentur, under a brief to ensure attractive returns for investors in low-carbon electricity systems while keeping a lid on costs for consumers, spoke of high interest in a statement.
“The extremely positive trend in bidding will be reflected in a significant commissioning number as from next year,” said Klaus Mueller, president of the authority.
The regulator will hold auctions for 10,000 MW each year up to 2028.
This happens under a remit to build up capacity successively on the way to meeting the country’s target of 80% of renewable power in the overall mix by 2030.
The price allotted in the November tender process arrived at 7.15 cents ($0.075 cents) per kilowatt hour (kWh), after bids ranged between 6.93 and 7.35 cents/kWh, and compared with a result of 7.33 cents in the last round in August.
Permits to build wind turbines were extended to 348 bidders, including big names such as RWE.
Ørsted Sells 50% Stake in Taiwan Wind Farm for $1.64B
Denmark’s Ørsted said on Dec. 11 it has agreed to sell a 50% stake in its Greater Changhua 4 offshore wind farm to Taiwan’s Cathay Life Insurance for about 11.6 billion Danish crowns (US$1.64 billion).
The site is part of Ørsted’s 920-MW offshore wind farms Greater Changhua 2b and 4, which the company is currently constructing and expects to finalize by the end of 2025.
The total sales price includes the 50% ownership share as well as a commitment to fund 50% of the cost of the wind farm, Ørsted said.
Battling to restore investor confidence, the offshore wind industry leader in February trimmed its investment and capacity targets and paused dividend payouts as part of a major review.
Ørsted will continue to own the remaining 50% ownership stake in the wind farm, Orsted said.
The transaction amount will be paid in 2024 and 2025, it added.
The Greater Changhua 2b and 4 offshore wind farms are located next to the 900 MW Greater Changhua 1 and 2a, which are in operation.
Together, the 1.82-GW Greater Changhua offshore wind cluster can produce enough energy to power nearly two million Taiwanese households, according to Ørsted.
