RMI analysis indicates that clean energy portfolios—combining solar, storage, and energy efficiency—are lower cost and lower risk than JEA's proposed gas plant. While JEA's 2023 estimates suggested gas was the cheapest option, updated capital costs (which have risen by 139%) and fuel price projections suggest a gas plant could cost $4.8 billion in NPV. In contrast, CEPs are estimated to cost between $2.1 and $3.4 billion depending on energy efficiency levels. Additionally, the gas plant is projected to cause over $1 billion in negative health effects across Florida, whereas CEPs could generate up to $757 million in local economic benefits and thousands of jobs.
