Solar & Storage

The US Department of Energy injected a colossal $26.5 billion loan package into Southern Company, backing 16 GW of diversified capacity additions and extensive transmission upgrades across Georgia and Alabama. This monumental federal investment, the largest in DOE history, targets a mix of battery energy storage systems (BESS), new gas generation, nuclear, and hydropower improvements, as reported by Energy Storage News, Georgia Recorder, and Power Magazine. While advocates immediately voiced concerns over ratepayer burden given the inclusion of gas generation, the sheer scale of this funding package signals a significant federal commitment to shoring up the grid, albeit with a technology-neutral approach under the Trump Administration.

Despite policy headwinds, the utility-scale solar sector continues its formidable growth trajectory. The US Energy Information Administration (EIA) forecasts a record-breaking 43.4 GW of new utility-scale solar PV capacity will come online in 2026 alone, a testament to the industry's underlying momentum. This projection comes as new projects continue to break ground and change hands. Recurrent Energy, a Canadian Solar subsidiary, sold its 200 MWh Fort Duncan battery energy storage system in Texas to Hunt Energy Network, underscoring continued investment and developer confidence in standalone storage assets, notes Energy Storage News.

California, a perennial leader in clean energy, plans to host the largest solar installation in the US, repurposing unused farmland in the Central Valley according to CleanTechnica. This mirrors successful strategies seen elsewhere, such as Rhode Island's Coventry Landfill Solar project, a new 5.74 MW solar array built on capped landfill space that went online this week, as reported by CleanTechnica. Further demonstrating innovative solar deployment, REC Solar and Ventura Energy completed a 1.73 MW solar project for Farmers Irrigation Company in Santa Paula, California, installing arrays on new reservoir covers that also support water distribution modernization, highlights Solar Power World. These diverse projects showcase the industry's agility in finding new sites and applications.

Wind Energy

Offshore wind continues its slow but steady march forward. Seatrium delivered the "C-Vess," a specialized vessel crucial for the Empire Wind project off the New York coast, despite previous disputes now reportedly resolved, according to Wind Power Monthly. This delivery signifies tangible progress for a sector that has faced considerable challenges, from supply chain kinks to permitting delays and the shifting political winds under the Trump administration. The timely arrival of specialized infrastructure remains critical for keeping these complex, capital-intensive projects on schedule and budget.

Policy & Markets

A key policy battle emerged on Capitol Hill as US Senators introduced a joint resolution aimed at reversing a recent IRS ruling that restricts the 5% safe harbor rule for utility-scale solar projects exceeding 1.5 MW under the investment tax credit. Senators argue this IRS move impedes clean energy development and could drive up energy prices, indicating the ongoing tension between administrative interpretation and legislative intent, as reported by Solar Builder. This pushback highlights the sector's vulnerability to policy shifts and the critical importance of tax credit stability, especially under an administration less inclined to prioritize renewable energy incentives.

The Intersolar & Energy Storage North America 2026 conference underscored the clean energy sector's current fragmented landscape, with panelists emphasizing the growing importance of state-level initiatives and interstate collaboration. This strategic pivot aims to maintain momentum for renewable energy projects amidst what many perceive as decreased federal support for solar under the Trump Administration, according to Solar Builder. The focus on local and regional partnerships reflects a broader industry adaptation to a less predictable federal policy environment.

Further addressing cost and regulatory hurdles, a US national lab report suggests that inverter-based approaches offer a cheaper and more accessible alternative to direct transfer trip (DTT) for shutting down distributed solar projects during outages. DTT costs frequently make solar projects uneconomical, leading to project withdrawals. The report champions undervoltage relaying and unintentional islanding detection—already part of existing inverter certification—as viable alternatives, offering a potential path to mitigate significant soft costs for developers, details PV Magazine.

LOOKING AHEAD

Southern Co. Ratepayer Scrutiny: Southern Company faces renewed advocacy group pressure regarding ratepayer impact from its $26.5 billion DOE loan and accompanying capital projects, particularly concerning costs for non-renewable generation.
IRS Safe Harbor Resolution Vote: The proposed Senate joint resolution to restore the 5% solar safe harbor rule requires close observation for its trajectory through Congress and potential White House reaction.
California Largest Solar Farm Details: Expect further details on the development timeline, financing, and exact location of California's planned largest solar installation in the Central Valley, with a close eye on any potential local opposition.

Today's Quick Answers

Q: What does the massive $26.5 billion DOE loan to Southern Company signal for mixed-resource grid development under the Trump Administration?

A: This unprecedented loan signals a clear Trump Administration priority: grid reliability and capacity expansion through a technology-agnostic approach, leveraging federal financing for large-scale utility projects across gas, nuclear, and renewables. While supporting some clean energy infrastructure like battery storage and transmission, it explicitly greenlights new fossil fuel generation, demonstrating a departure from policies exclusively favoring renewables seen in prior administrations. Developers should anticipate continued federal support for comprehensive grid-hardening projects that prioritize a diverse energy mix, even if it includes fossil assets.

Q: Why does the Senate's push to restore the 5% solar safe harbor rule matter so significantly for utility-scale solar projects?

A: Restoring the 5% safe harbor rule directly impacts the financial viability and planning certainty for utility-scale solar projects over 1.5 MW, which constitute the bulk of planned and operational capacity. The IRS's recent change created ambiguity and increased financial risk for developers, potentially delaying or even canceling projects by altering their investment tax credit (ITC) eligibility. A return to the previous rule would provide critical stability and predictability for developers like Avantus, Invenergy, and Intersect Power, allowing them to confidently forecast project economics and accelerate deployment, especially as the EIA forecasts record solar growth in 2026.

THE BOTTOM LINE: Federal capital remains available for critical grid infrastructure, even if mixed with fossil fuels, while the solar industry battles for tax credit stability amidst record-breaking deployment forecasts and leverages state-level collaboration.
