Total capital expenditure in US clean energy and manufacturing hit $74 billion during the first half of 2026, with annual investment poised to reach $180 billion, according to Crux’s 2026 Mid-Year Market Intelligence Report. Key drivers include surging power market investment, rapid data center load growth, and a shifting risk environment, signaling an intensified push toward new project financing and technology adoption.
Key figures
$74 billion deployed in H1 2026
$180 billion expected 2026 total capex
$59 billion in greenfield debt financing
$70 billion 2026 tax credit monetization target
Capex momentum rises with market shifts
The first half of 2026 saw robust US clean energy and manufacturing capital deployment, with capital markets continuing to move despite ongoing regulatory changes. Crux’s analysis points to a strong pipeline, fueled largely by power sector investment and the accelerating demand for energy from hyperscale data centers and AI-related compute loads. This rapid growth in load is driving liquidity through traditional and new channels, allowing projects to proceed even as policymakers alter the rules for legacy subsidies such as the production and investment tax credits.
Wind and solar projects previously relied on federal tax credits, but eligibility criteria for these incentives shifted as of July 4, 2026. Only projects that began construction before this cutoff date are eligible if they come online by 2028; those in progress may still qualify until roughly 2030 if they move expeditiously.
The phasing of these credits, and the resulting focus on project timelines, has added urgency for developers and investors to secure timely financing, creating intense competition for quality sites and contracts. Alongside renewables, energy storage has rapidly emerged as a priority segment, with market economics increasingly enabling storage-focused projects to compete without subsidies as firming resources for both grid and digital infrastructure use cases.
Data center load and power demand
AI-driven capital expenditures and the growth of large-scale data centers are exerting considerable influence on the energy sector’s financial outlook for 2026. Electricity demand spikes, particularly for hyperscaler and high-performance compute installations, have increased the urgency for new capacity and accelerated investment decisions by both utilities and independent power producers. This new demand is shaping procurement and interconnection strategies, as developers seek to match capacity additions with corporate or wholesale off-take agreements.
The competition for access to affordable, reliable power has been intensified by energy supply constraints and regional grid limitations. Developers are responding by increasing investment in projects with strong interconnection prospects and focusing on flexible financing arrangements that account for evolving policy and market dynamics. Affordability pressures are mounting in regions with acute demand growth, especially in ISOs like ERCOT and PJM, where data center expansion is colliding with grid congestion and permitting backlogs.
Clean energy financiers are adapting to this environment by emphasizing projects with clear paths to completion, bankable off-take, and risk management approaches tailored to load growth from digital infrastructure. As capex outlays remain strong, the mix between utility-scale, distributed generation, and storage is being recalibrated, but projects tied to data center loads are generally winning out in competitive financing processes.
Tax credit market developments
Tax credit monetization continues to be a major lever for clean energy deal structuring. Crux projects overall tax credit value across tax equity, preferred equity, and transfer markets to reach $70 billion by the end of 2026, marking an 11% increase over prior year levels. Transferable tax credit volume hit $21 billion in H1 2026, with a record $14.9 billion closed in the second quarter as tax buyers finalized their 2025 obligations. Crux forecasts full-year transfer activity will land between $47.5 billion and $49 billion, reflecting robust secondary market liquidity.
Tax equity and preferred equity volumes are also expanding, with $46.3 billion projected in 2026. Notably, preferred equity volume is expected to more than double from 2025, rising from $3.05 billion to $7.45 billion. Preferred equity is gaining popularity among investors, particularly in tech-neutral 48E projects, which allow greater ownership flexibility compared to traditional tax equity structures limited by Prohibited Foreign Entity (PFE) rules.
This shift in deal structuring mechanics is notable for institutional investors and developers seeking to access new pools of tax credit value without running afoul of tightened ownership restrictions introduced in recent federal policy updates.
Debt and equity flows accelerate
Greenfield debt financing for US power, manufacturing, and clean fuels increased 12% from H2 2025 to reach $59 billion in the first half of 2026. Given this growth trajectory, Crux expects total clean energy lending to climb to $143 billion by the end of the year, a 19% year-over-year increase. This expansion highlights both the strong appetite among lenders for clean infrastructure exposure and the robust demand from developers bringing new projects forward in a tighter policy environment.
Competitive terms in both senior and preferred lending reflect not only increased liquidity but heightened scrutiny on deal structure, policy risk, and guaranteed off-take agreements. Institutional buyers are looking for assurances in execution, timeline, and creditworthiness, while developers are facing pressure to de-risk portfolios and front-load equity commitments.
Risk premiums and spreads remain sensitive to federal policy shifts, especially provisions such as the OBBB Act’s PFE clause, which can restrict participation for foreign entities. This is reordering the market for secondary tax credit purchases and prompting innovations in equity syndication to address ownership caps.
Policy, regulation, and risk
Legislative and regulatory changes in 2026 are exerting significant influence on transaction structure and investment pacing. The expiration of certain tax credits and more aggressive enforcement under the OBBB Act have put regulatory risk at the forefront of deal negotiations. Prohibited Foreign Entity status has become the dominant variable impacting structure and pricing, particularly for large-finance transactions that would have previously relied on familiar tax equity mechanics.
At the same time, sector participants are showing resilience by pursuing diversified transaction models and adapting to the evolving federal posture. As construction deadlines tied to tax credit eligibility approach, sponsors are working to ensure projects are shovel-ready and closing ahead of uncertain rule changes. The risk environment is shifting, but the overall capital commitment to clean energy projects appears undiminished, with new strategies emerging to monetize federal incentives and hedge against future rule clarifications.
Market observers can expect continued adaptation and innovation from both the buyer and seller sides in financing negotiations. While some projects may face executional hurdles, particularly around qualification windows or foreign-ownership limits, the broader investment cycle in clean energy is maintaining momentum due to these structural adjustments.
What this means for buyers
Sustained capital inflows and shifting deal structures create opportunities and challenges for institutional buyers evaluating US clean energy assets. Understanding new risks from evolving tax incentives and ownership restrictions is crucial for due diligence. The rapid rise of data center-driven demand and storage as a project focus may widen deal flow but raise competition for grid access. Buyers should prioritize regulatory agility, bankable off-take, and proactive risk management when evaluating transactions in 2026’s capital-intensive landscape.
