Investors Back US Renewable Energy Projects But Want Market Uncertainties Fixed

US renewable energy is set to gain $120 billion in investment in 2026 and could add a record level of new capacity, up to 62 GW, as projects rush to meet a power demand surge and claim soon-to-end solar and wind project tax credits, said the American Council on Renewable Energy at its May 13 sector finance conference in New York City.
Renewable energy in the U.S. is set to gain $120 billion in investment in 2026 and could add a record level of new capacity, up to 62 GW, as projects rush to meet a power demand surge and claim soon-to-end solar and wind project tax credits, said the American Council on Renewable Energy in two new reports and at its May 13 sector finance conference in New York City.
But federal actions that undermine projects, still-unclear tax credit rules and slow connection to the grid could tamp down future investment, experts said. In a late April study for ACORE, S&P Global said solar and battery storage would have the most investment this year, about $53 billion and $22 billion, respectively.
"We have been building renewables first, not just because it's clean power but because it's fastest," said Brian Callaway, CFO of developer Copia Power. “What keeps me up at night are timelines for transmission. They are taking too long and will continue to be a problem. Digital demand is real. Even if comes down a bit, demand is there." Claudia Correa Welch, /managing director of Bank of America, noted: "I'm not concerned about availability of capital, That's not the primary constraint. New sources of capital are coming into the sector. The challenge is the ability to execute. Things are happening very fast. How fast can you build is really the question."
Federal tax credit use grew 10% in 2025 over 2024, to $45-$50 billion. “Investment now is 70% in non-generation areas, much changed [from recent years],” said Christopher Wilfong, an S&P Global director. Of 36 U.S. and multinational finance leaders surveyed by ACORE who invested more than $1 billion in domestic clean energy in 2025, 69% plan to increase their investments in 2026. Of project sponsors also surveyed, 83% will maintain or boost development this year, and none with $100 million or more in revenue will reduce it. Notably, no ACORE-surveyed investors said they will consider coal power spending in the near term, despite major administration incentives and lobbying.
Meanwhile, corporate commitments for clean energy reached a new milestone in 2025 and remain strong in the first months of 2026, said the Corporate Energy Buyers Association, which has about 300 members, in its 2026 State of the Market report. It said corporate buyers announced more than 27 GW of U.S. clean energy capacity procured in 2025 and some 17 GW procured in the first quarter of 2026.
“Corporate buyers are no longer just participants in clean energy markets,” said group CEO Rich Powell. “They are shaping the grid itself.” Solar remains the leading clean technology by capacity, in 2025. but nuclear surpassed wind for the first time as the second-largest tech favored by buyers. Investments in geothermal, hydropower, energy storage and emerging ones such as fusion and carbon capture also increased,. But the group said Infrastructure constraints, policy uncertainty and geopolitical instability are contributing to higher power purchase agreement prices.
Deadlines Loom to Use Federal Tax Credit
Federal tax credits requiring wind and solar projects to begin construction by July 4 and start operating by the end of 2027 are key incentives to advance work now. But vague federal rules on whether project components or investment can be sourced from countries “of concern,” such as China and Russia, could keep more renewable sector developers from claiming these incentives,

aid ACORE: "Surveyed investors explicitly named federal regulatory policy shifts and interconnection delays as their greatest roadblocks Industry leaders collectively emphasized that long-term deployment hinges entirely on Congress delivering stable, durable policy certainty."
Also, administration delays in approving roughly 80 projects, mostly wind power on military sites and elsewhere, have taken wind off investors’ top ten most attractive markets, the ACORE reports concluded. A Massachusetts court last month ordered the Trump administration to stop blocking 57 GW of clean energy projects, but it is expected to appeal the ruling.The conrinued government effort to derail the sector is expected to hinder progress of congressional negotiations on project permit reform, another market incentive investors want to see.
"I am having pipeline discussions all the time with lenders. Solar and battery storage projects will continue to be competitive," Kevin Smyth, CEO of developer-operator Cypress Creek Renewables, told attendees. "If you think gas will bail out the whole industry, it won't happen. There is a huge role for battery storage ahead. The next 24 months will be pretty dynamic."
