Wood Mackenzie Raises U.S. Wind Forecast as Tax Credit Sprint Meets Tech Demand
A 5% upgrade to the firm's five-year greenfield wind outlook reflects a developer rush on expiring federal tax incentives and contracted demand from large technology companies.
Wood Mackenzie lifted its five-year forecast for U.S. greenfield wind development by 5% in a July 20 (2026-07-20) note, citing contracted demand from large technology companies and a developer push to qualify projects before expiring federal tax credits close. "Large technology companies are turning to wind power as an additional energy source to meet their growing needs," the firm wrote.3
The revision arrives as the U.S. power market faces an acute supply shortfall. Bank of America analysts estimated on July 17 (2026-07-17) that the country will need more than 230 GW of new generating capacity over the next five years, while regulated utilities are expected to add only about 93 GW of accredited supply — a gap exceeding 100 GW that developers of all stripes are racing to fill. Data centers alone could account for a substantial portion of that incremental demand, BofA said.7
The tax credit window is the immediate driver. Canary Media reported on June 15 (2026-06-15) that wind and solar developers had just weeks left to lock in lucrative federal tax incentives following changes signed by President Trump. That deadline was either closing or had passed by the time Wood Mackenzie published its July 20 note. The firm's 5% upgrade likely captures projects that qualified in the final sprint. Wood Mackenzie's note does not break out how much of the upgrade reflects locked-in pull-forward versus genuine new pipeline entering development.3
Post-deadline wind projects face a different underwriting reality. Without the subsidy backstop, developers depend more heavily on long-term corporate power purchase agreements to close the economics. Technology buyers have been willing to sign, but a signed contract is not a spinning turbine. Permitting delays, interconnection queues and supply chain timelines all sit between an offtake agreement and first power.3,7
Part of the greenfield momentum also reflects the near-total collapse of U.S. offshore wind development. E&E News reported on May 26 (2026-05-26) that the Trump administration had been paying companies to exit offshore contracts, and Canary Media noted in April (2026-04-21) that U.S. offshore development had "all but screeched to a halt." E&E News found that financiers had grown wary of committing capital to the sector given the administration's track record. Capital retreating from offshore has to find a new home. Onshore greenfield is one of the few viable outlets left in domestic clean energy.2,1
The gas price outlook adds texture to the wind contracting case. Wood Mackenzie argued in a separate July 5 (2026-07-05) report that U.S. natural gas prices are set to rise through 2035, driven by AI data center demand and expanding LNG export infrastructure. NYMEX Henry Hub front-month stood at $2.87/MMBtu at Friday's (2026-07-24) settlement, well below the firm's forecast of prices approaching $5/MMBtu by 2035. Corporate buyers willing to sign decade-long wind contracts are partly hedging against that trajectory.5
The consensus case for greenfield wind has real vulnerabilities, though. Political support for the tax credit framework remains contested, and a further legislative reversal could erode the economics of projects still in development. Interconnection queues have ballooned as the gap between gigawatts requested and gigawatts built has widened. Technology companies are simultaneously being pursued by solar developers, battery storage operators and nuclear suppliers. The Atlantic Council noted in a July 1 (2026-07-01) policy paper that nuclear power already provides 55% of U.S. carbon-free generation, and several tech companies have signed nuclear offtake agreements that directly reduce the market available to wind.6,7
Storage is growing quickly enough to complicate the picture further. Wood Mackenzie and the American Clean Power Association reported in June (2026-06-23) that the U.S. added 3.3 GW/8.4 GWh of energy storage in the first quarter of 2026, with utility-scale, residential and commercial segments all posting records. Battery systems capable of providing firmed around-the-clock power are an increasingly credible alternative to wind-backed PPAs for data center operators whose reliability requirements go beyond raw capacity.4
Interconnection queue data in the second half of 2026 will be the first real test of this upgrade. A 5% increase in projected greenfield wind means little if the grid constraints that have bottlenecked previous pipelines persist. Post-deadline, developers no longer have the tax credit backstop to justify holding positions in speculative queues while timelines stretch — and tech buyers shopping for firmed power have more options than they did a year ago.7,3
