US clean energy investment on track for record $180 billion in 2026

Investment in United States clean energy technology is tracking toward a record high of $180 billion by the end of 2026, despite significant rollbacks of previous federal incentives. Capital expenditures in the sector reached $74 billion in the first half of the year, according to the State of Clean Energy Finance: 2026 Mid-Year Market Intelligence Report published by fintech firm Crux. This surge in spending is being driven by market forces that operate independently of federal government policy, indicating a resilient investment climate even after the tax law changes of the previous year.

Alfred Johnson, CEO and co-founder of Crux, stated that the market is demonstrating resilience in the face of regulatory shifts. He noted a significant volume of investment activity following the recent legislative changes. The primary driver of this capital influx is the insatiable energy demand generated by data center hyperscalers and the broader artificial intelligence boom. These sectors are fuelling a wave of investment into various energy projects, with a particular emphasis on renewable sources due to their advantages in energy security and affordability. These benefits have become increasingly apparent amid recent volatility in fossil fuel markets, which has been exacerbated by the war in Iran and resultant supply chain vulnerabilities.

John Ketchum, CEO of NextEra Energy, recently told Reuters that renewables and storage remain the fastest method for adding new electricity to the grid until additional gas-fired generation capacity can be constructed. Miguel Stilwell d’Andrade, chief executive officer of the Portuguese electric utilities company EDP, described the current period as one of the best times to invest in United States renewables in the last two decades. In line with this assessment, EDP is directing approximately $5.3 billion, which represents more than half of its capital expenditures, toward United States renewable energy projects over the next three years.

This expansion of renewable capacity is accompanied by an unprecedented increase in battery storage buildout, which is rapidly transforming the national energy grid. Over the past three years, utility-scale battery storage capacity has grown at an average rate of 70 percent per year, reaching a total of 52 gigawatts. Of this total, 8.3 gigawatts, or nearly 16 percent, was added in the first half of the current year alone. Industry reports indicate that this expansion relies heavily on co-locating batteries with solar photovoltaic plants to exploit wholesale price arbitrage across major energy markets. This model allows operators to store excess clean energy during peak production hours for release during the evening, when demand rises and electricity rates reach a premium. This lucrative business model has sparked a construction boom across solar-heavy states, establishing temporary energy storage as a primary driver of modern grid infrastructure.

Grid operators have plans to add another 54 gigawatts of battery capacity by the end of 2028. This trajectory implies that the nation’s energy storage capacity will double again by 2030 compared to current levels. The United States is not the only market experiencing this growth, as the energy storage renaissance is proving to be a global trend. China leads the buildout by a wide margin, controlling more than half of global capacity. However, other major economies are moving to secure a foothold in the rapidly expanding market. The European Union formalised a plan this month to triple the bloc’s energy storage capacity by 2030. European leaders are relying on energy storage, alongside renewable energy expansion, to stabilise the continent’s energy markets and protect member states from future energy crises.
