US Target Aims to Make Solar Energy Cheaper Than Fossil Fuels Without Subsidies
Washington, Tuesday, 11 August 2026.
The Department of Energy aims to cut solar power costs to three cents per kilowatt-hour by 2030, allowing clean energy to outcompete fossil fuels without relying on subsidies.
Sunshot 2030 Cost Targets
The United States Department of Energy (DOE) has reaffirmed its commitment to the Sunshot 2030 initiative, aiming to reduce unsubsidized utility-scale photovoltaic generation costs to $0.03 per kilowatt-hour by 2030 [1]. This objective represents a significant -50 change from the 2017 benchmark of $0.06 per kilowatt-hour, positioning solar energy to economically outperform traditional fossil fuel generation without relying on federal tax credits [1]. The initiative originally launched in 2011 when solar provided less than 0.1% of domestic power, contrasting sharply with 2017 capacity levels that exceeded 47 gigawatts [1].
Integrating Storage and Grid Stability
To ensure reliability alongside cost reductions, the DOE targets concentrating solar power costs at $0.05 per kilowatt-hour for baseload configurations with at least 12 hours of thermal storage [1]. Peaking configurations with less than six hours of storage are targeted at $0.10 per kilowatt-hour, while federal roadmaps set a 2040 goal of $100 per kilowatt-hour for 8-hour battery storage systems [1]. Federal agencies are funding research in advanced heat transfer fluids and deploying tens of millions in funding for grid-forming inverter technology to manage these inverter-based resources [1].
Economic Implications and Market Parity
Federal urgency is driven by statutory phase-outs of Investment Tax Credits and Production Tax Credits, requiring the industry to achieve unsubsidized parity faster than previously modeled [1]. Solar energy is currently the fastest growing and most affordable source of new electricity in America, supporting household savings and grid reliability [2]. As the cost of solar energy systems drops significantly, more Americans and businesses are taking advantage of clean energy to support energy independence and economic opportunities [2].
