The Infrastructure Investment Case for Solar and Storage

Why It Matters

Solar and storage offer predictable, fuel‑free generation that aligns with the urgent need for fast, scalable capacity, reshaping infrastructure portfolios and attracting trillions of dollars of capital.

Key Takeaways

• Data center power demand set to double by 2035.
• 30 GW solar and 12.6 GW storage added in early 2025.
• Utility‑scale solar now exceeds 160 GW, storage over 137 GWh.
• Solar LCOE fell ~90%; battery costs dropped >90% since 2010.
• Tax‑credit transferability expands capital pool for solar‑storage projects.

Pulse Analysis

The United States is confronting a seismic shift in electricity consumption. Hyperscale data centers alone are projected to more than double their load from 35 GW today to 78 GW by 2035, while advanced manufacturing and residential electrification add further pressure on grids that are already operating near capacity. Traditional firm resources such as combined‑cycle gas turbines face long lead times and supply‑chain backlogs, and nuclear or geothermal projects carry extended construction risk. This environment forces utilities and large energy buyers to prioritize assets that can be built quickly, financed efficiently, and deliver reliable power.

Solar photovoltaics and battery storage have answered that call. Over the past fifteen years the levelized cost of electricity from utility‑scale solar has fallen roughly 90 %, making it competitive with, or cheaper than, many fossil‑fuel options. Simultaneously, lithium‑ion battery pack prices have dropped more than 90 % since 2010, enabling storage to shift solar output into high‑value periods and smooth intermittency. Longer module lifespans—now often 30 years or more—further improve economics. The Inflation Reduction Act and the ability to sell federal tax credits to third parties have broadened the investor base, reducing reliance on traditional tax‑equity structures and accelerating capital deployment.

For infrastructure investors, the implication is a re‑classification of solar and storage from thematic ESG bets to core, cash‑flow‑stable assets. Their front‑loaded capital costs, absence of fuel price exposure, and predictable long‑term output align with the risk‑adjusted return profiles of classic infrastructure like highways or pipelines. Consequently, capital flows have surged, with $2.3 trillion invested globally in the energy transition last year, of which roughly $1.2 trillion targeted renewables and grid upgrades. As demand continues to outpace supply, solar‑plus‑storage is poised to become a cornerstone of future utility portfolios.
