RMI analysis indicates that Clean Energy Portfolios (CEPs) are more cost-effective and lower risk than the natural gas plant proposed by the Jacksonville Electric Authority (JEA). The report finds that JEA's updated capital cost projections for the gas plant are 139% higher than its 2023 estimates, while CEPs—particularly those leveraging high energy efficiency—offer lower net present value (NPV) costs and significant local economic benefits without the negative health externalities associated with gas combustion.

This 2021 update from RMI analyzes the economic, health, and jobs impacts of 'clean energy portfolios' (CEPs)—which combine solar, wind, storage, demand flexibility, and energy efficiency—as alternatives to the more than 88 gigawatts of gas power plants proposed across the United States in 2021.

This RMI briefing examines the economic risks of continuing to invest in natural gas power plants and interstate pipelines in the United States, arguing that falling costs of clean energy portfolios make these investments prone to becoming stranded assets.
