Global investment in renewable energy reached $327.5 billion in the first half of 2026, with co-located solar-plus-storage projects in the United States and Australia attracting a record $25 billion. According to BloombergNEF, this sharp increase reflects a strategic shift as developers and capital providers adapt to mounting revenue risks and policy-driven market dynamics.
Key figures
$25 billion invested in co-located solar-plus-storage, H1 2026
$327.5 billion global renewables investment, H1 2026
54% growth in US renewable energy investment year-on-year
Shift toward hybrid projects
The first half of 2026 continued a trend of US capital flowing into flexible power assets, with nearly double the investment in hybrid solar-plus-storage compared to late 2025. The pivot was driven by revenue pressure from price cannibalization, curtailment risk due to grid congestion, and evolving market rules impacting traditional standalone solar economics.
Co-location enables developers to store excess solar generation for discharge during peak demand or higher-priced market intervals, addressing volatility in power prices and improving project revenue certainty. BloombergNEF’s data show the United States and Australia leading this surge, reflecting both regions’ policy incentives and grid modernization programs.
For project developers, hybrid configurations increasingly mitigate financial risk and unlock value under existing offtake structures or merchant power arrangements. The scale and rate of US investment suggest that these projects are rapidly moving from niche installations to a core utility-scale model for the coming years.
Standalone solar faces headwinds
The report highlights a notable 20% year-on-year decline in financing for standalone utility-scale solar PV, totaling $75.4 billion, the sector’s lowest level since the market uptick began in 2021. In contrast to the hybrid surge, conventional solar projects are increasingly exposed to market price declines during periods of surplus generation.
These challenges stem from grid saturation in key ISO and RTO markets, as well as the tendency for supplementary solar output to depress energy prices during daylight hours. With grid curtailment and declining capture rates affecting returns, investors are recalibrating portfolios toward assets that maximize dispatch flexibility or stack multiple revenue streams via storage participation.
Wind investment, while also subject to policy and market shifts, has not declined as sharply; onshore and offshore wind remain integral, though drag in China and offshore development softened the global outlook.
US market dynamics accelerate deployment
The United States emerged as the world’s second-largest market for new renewable investment in H1 2026, outpacing the European Union and only trailing China. The report notes 54% year-over-year growth in total US renewables capital deployment, bolstered by time-sensitive project financing runs to qualify for federal tax credits.
This window for tax incentives, scheduled to phase down after 2026, spurred both developers and buyers to close transactions and begin construction ahead of deadline-driven cliffs. During the period, US solar investment alone increased to $45.8 billion, a 41% jump that coincides with wind investment more than doubling to $13.8 billion.
Data center expansion and surging electricity demand from the digital economy were key demand drivers, with project sponsors seeking to secure grid interconnection and long-term contracts to match load growth. The trend is expected to maintain near-term activity even as overall market growth may pause before resuming in 2027.
Policy and revenue considerations
BloombergNEF projects that total new renewable installations in 2026 will fall below 2025 levels, marking the first such decline in over a decade. This anticipated softness results from a combination of regulatory changes, price uncertainty, and slowed growth in the Chinese and offshore wind sectors, though US market activity may partially offset the global dip through 2030 due to existing incentives.
Hybrid project structuring, particularly in markets with high congestion or volatile prices, is emerging as the preferred approach for institutional investors. By combining solar and storage, asset owners achieve better grid value realization and enhanced optionality to participate in ancillary service or capacity markets.
Looking ahead, developers eyeing projects with a 2027 to 2030 commercial operations date may need increasingly sophisticated market analytics, especially as federal incentives come to an end and merchant risk returns to the forefront of buyer and lender considerations.
What this means for buyers
Power and storage project developers operating in the United States should note that $25 billion was invested in co-located solar-plus-storage assets in H1 2026, nearly double the prior period. This rapid rise in hybrid project investment is a direct response to both regulatory-driven tax credit deadlines and increasing market risk from standalone solar. Buyers prioritizing flexible grid assets and seeking to secure interconnection before incentive phase-downs will face heightened competition this quarter.
