The U.S. Department of Energy's $26.5 billion loan package for Southern Company still stands as one of 2026's biggest grid-finance moves, but the story looks clearer six weeks later. Alabama Power has now moved into active installation at its Gorgas battery site, with Tesla Megapacks arriving through early March, giving this financing package a visible on-the-ground storage project instead of a generic future pipeline. In Europe, Trina Storage and Gore Street Capital have filled in more of the roadmap behind their new fund. The platform is still targeting about €1 billion and 12 GWh across the continent, but the companies now say first project signatures are expected by mid-2026, with initial deliveries targeted for the fourth quarter. That gives the fund a much tighter execution timeline than this article had when the deal first broke. A utility-scale battery storage installation. Image: AI-generated DOE's $26.5 Billion Bet on Southern Company The loan package, split between Alabama Power and Georgia Power, will fund development or enhancement of more than 16 GW of electricity generation. That includes 5 GW of new gas-fired capacity, 6 GW of nuclear power improvements through uprates and license renewals, hydropower upgrades, battery storage systems, and over 1,300 miles of transmission and grid improvement projects. When fully disbursed, the DOE estimates the loans will cut Southern Company's interest costs by more than $300 million per year , savings the agency says should translate into lower electricity prices for customers across the Southeast. $26.5B Total DOE loan package 16+ GW Generating capacity covered $300M+ Projected annual interest savings Alabama Power's 2025 integrated resource plan includes both traditional battery storage (available from 2028) and medium-duration energy storage systems with roughly 12 hours of capacity (available from 2033). The utility announced Alabama's first utility-scale BESS last March, a 150 MW project in Walker County built on the site of the retired Gorgas coal plant. Southern Company's portfolio spans nuclear, gas, hydro, and storage. Image: AI-generated Southern Company has also been exploring non-lithium technologies. In January, the company announced plans to install an 80 kW/1.5 MWh iron-sodium battery from Inlyte Energy at its test site in Wilsonville, Alabama. And in 2024, it completed testing of a concrete thermal energy storage pilot at a gas plant in the state, claimed at the time to be the world's largest of its kind. Georgia Power, meanwhile, opened a 2025 Request for Proposals to acquire 500 MW of BESS, with the procured systems expected online by the end of 2031. The subsidiary's resource plan also models compressed air energy storage and pumped hydro as potential medium-duration options. Trina Storage and Gore Street Target 12 GWh Across Europe At the Energy Storage Summit 2026 in London this week, Trina Storage (the BESS division of Trinasolar) and fund manager Gore Street Capital unveiled a partnership for a new EU-focused private battery storage fund. The venture is targeting a total size of roughly $1.18 billion (€1 billion), including primary commitments and co-investments, by the end of 2026. The deal was announced at the Energy Storage Summit 2026 in London. Image: AI-generated The fund plans to deploy 12 GWh of long-term BESS projects across the continent, with initial target markets including Germany, Ireland, Poland, the Iberian Peninsula, and Italy. First project signatures are expected by mid-year, and initial deliveries are targeted for Q4 2026. Why a Private Fund? Publicly listed BESS funds in the UK have struggled with revenue volatility and depressed share prices. The Harmony Energy Income Trust was sold and delisted in 2025. Gore Street's shift to a private structure reflects a broader industry move toward capital sources that can tolerate longer investment horizons without public-market pressure. Trina Storage brings system integration expertise and manufacturing scale to the partnership, while Gore Street contributes project development experience from its existing UK and international portfolio, which includes a 200 MW/400 MWh system in California. Recurrent Energy Sells 200 MWh Texas Battery Project In a separate deal announced the same day, Recurrent Energy (a subsidiary of Canadian Solar) sold its Fort Duncan battery energy storage project in Texas to Hunt Energy Network. The system is rated at 200 MWh. Texas continues to attract battery storage investment alongside its massive wind and solar fleet. Image: AI-generated Texas has become a hotbed for grid-scale battery storage, driven by the state's deregulated power market, extreme weather events that have exposed grid vulnerabilities, and a booming renewable energy sector that creates natural demand for storage to manage intermittency. ERCOT, the state's grid operator, has seen battery capacity grow from virtually zero a few years ago to multiple gigawatts installed. Hunt Energy Network, the buyer, has been building a portfolio of flexible generation and storage assets across ERCOT. The Fort Duncan acquisition adds to a growing list of BESS projects changing hands in Texas as early-stage developers build and sell to operators focused on long-term grid services revenue. What Changed After Publication Alabama Gorgas moves from plan to installation Alabama Power says Tesla Megapacks started arriving at the retired Plant Gorgas site on Feb. 2. The project uses 92 Megapacks, 46 medium-voltage transformers, and a control house tied directly into the utility's high-voltage grid. Performance 150 MW, roughly 300 MWh Once commissioned, the Gorgas system is expected to store 150 MW of electricity, enough to serve about 9,000 homes for two hours during peak periods. Alabama Power says the system can charge in a little over two hours. Europe Fund timeline is sharper now Trina and Gore Street now say the first project signatures should land by mid-year, with initial deliveries planned for Q4 2026. Ireland and Poland are among the most advanced pipeline markets, with Germany, Iberia, and Italy also in view. Why it matters Capital is being matched with execution The new details matter because they show storage money moving beyond announcements. In the U.S., hardware is already landing on site. In Europe, developers are putting dates on signatures and deliveries. The Bigger Picture: Capital Flowing In From All Directions Battery manufacturing capacity is scaling to meet surging demand. Image: AI-generated This week's announcements share a common thread: battery storage has moved from a niche technology to a core component of energy infrastructure planning. Government loans, private equity funds, and project acquisitions are all converging on the same conclusion. Grid-scale storage is essential, and the economics increasingly support it. The DOE's $26.5 billion package is notable not just for its size but for what it includes alongside storage. By bundling BESS with nuclear uprates, gas generation, and transmission upgrades, the loan reflects a pragmatic approach to grid reliability: storage works best as part of a diversified portfolio, not as a standalone solution. In Europe, the Trina-Gore Street fund highlights a different dynamic. Public markets have punished standalone battery storage funds, but private capital sees opportunity in the same assets. The 12 GWh target across multiple EU markets suggests that European utilities and regulators are creating enough revenue certainty (through capacity markets, ancillary services, and policy mandates) to attract long-term investment. The pace of deals is accelerating, but the more interesting shift is how quickly those announcements are hardening into projects. Southern Company's storage plans are no longer just IRP language, the Gorgas site is now stacked with delivered hardware. In Europe, Gore Street's private-fund model is a sign that storage developers are looking past the volatilit
