Global Solar-Plus-Storage Investment Hits Record $25 Billion
Investment in colocated renewable energy projects, dominated by solar-plus-storage, reached a record $25 billion globally in the first half of 2026
Global investment in colocated renewable energy projects hit a record $25 billion in the first half of 2026. This figure is nearly double the previous record set in the second half of 2025.
This surge is driven by growing interest in pairing solar farms with grid batteries. Solar power's intermittent generation often fails to align with electricity demand. Adding storage allows these projects to function more like traditional, dispatchable power plants, ramping output up or down based on grid needs and power prices.
Investment Trends and Grid Impact
The $25 billion invested marks a dramatic jump for the sector. While the category includes any mix of solar, wind, and storage, solar-plus-storage dominates the spending. This growth contrasts with stagnation in overall renewable energy investment during the same period.
BNEF identifies the United States as a leading country for solar-plus-storage investment. This aligns with a thriving U.S. Grid battery sector, which recently had its best quarter ever for installations. Nearly half of the storage capacity added in that quarter was built alongside solar farms. Falling battery cell costs and growing developer comfort with the technology are cited as key factors.
The Broader Renewable Energy Context
Despite the boom in colocated projects, they remain a relatively small portion of total renewable energy investment. Broader clean energy investment stayed flat between the first half of 2026 and the second half of 2025. Investment in offshore wind, in particular, plummeted.
BNEF notes that poor auction results in countries like Denmark and Germany reduced the number of projects able to secure financing. The firm concludes, however, that "the numbers show that the broader growth story for renewables remains intact."
The Challenge of Scaling Up
Canary Media's report shows a critical challenge. To reduce emissions while meeting rising global energy demand, overall clean-energy investment must accelerate rapidly. The current growth in solar-plus-storage, while significant, is not sufficient on its own.
The data illustrates a clear shift in grid and generation management. Investors are increasingly backing projects that combine generation with storage, aiming for more reliable and valuable clean power. The record spending signals a major step in grid hardening through flexible, hybrid generation assets. The focus now is on expanding this momentum across the entire clean energy sector.
