Lazard Report: Renewables Remain Cost-Leaders Despite Rising Costs

Lazard's 2026 Levelized Cost of Energy+ (LCOE+) report confirms that renewable energy remains the lowest-cost option for new power generation despite inflationary pressures, tariffs, and supply chain constraints affecting virtually all generation technologies. The U.S. power sector is grappling with soaring electricity demand driven by data centers, artificial intelligence, and industrial electrification. Solar and wind continue to offer the lowest unsubsidized levelized cost for new generation, expected to dominate near-term U.S. capacity additions. Meanwhile, developers are pushing forward with new natural gas projects despite gas-fired generation reaching its highest LCOE in 15 years and facing extended equipment delivery timelines. The report emphasizes the need for a diversified generation portfolio to meet rapidly growing electricity demand. Existing power plants have become more economically attractive as escalating construction costs, inflation, tariffs, and permitting delays make replacement increasingly expensive. Higher utilization rates allow existing assets to spread fixed costs across greater output, though conventional plants remain exposed to volatile natural gas and coal prices. Battery energy storage costs reversed recent declines this year, driven by tariffs on lithium-ion imports and U.S. restrictions on supply chains linked to China, accelerating diversification toward Southeast Asia and domestic manufacturers. Despite higher costs, storage remains critical for integrating intermittent renewables. The report highlights a broader market shift as developers prioritize technologies that deliver capacity quickly amid tightening supply-demand dynamics, increasing the value of both renewable energy and existing generation assets while reinforcing the need for full-system investment.

Shifts in Cost Competitiveness

■Solar and wind maintain the lowest unsubsidized levelized cost for new generation, while natural gas hits a 15-year high.

■Battery storage costs rose due to tariffs and supply chain diversification efforts away from China.

■Existing power plants gain economic appeal amid rising construction costs and permitting delays.

Surge in Energy Demand

■Data centers, artificial intelligence, and industrial electrification drive unprecedented electricity demand in the U.S.

■Natural gas projects proceed despite long lead times and supply chain bottlenecks.

■Renewables and existing assets play a critical role in maintaining grid reliability.

Markets are navigating this landscape with a focus on sustainable renewable investments. However, supply chain diversification efforts and rising costs underscore the need for strategic frameworks, particularly for Asia-Pacific investors. Lazard's findings reinforce the priority of cost-effective solutions in the energy sector while highlighting the indispensable role of storage technologies for integrating intermittent renewables.
