In this analysis, we assess where solar and storage have the potential to replace existing Florida peaker power plants and where their deployment may yield the greatest environmental health and equity benefits. Across Florida, 35 gas- and oil-fired peaker power plants and peaking units at larger plants help meet statewide peak electric demand. These facilities include primarily gas turbines as well as internal combustion engines and steam turbines. One-third burn primarily oil, and two-thirds burn natural gas, although many burn both. Nearly half of Florida’s peaker units are located at larger plants, including two located at coal plants. Many of Florida’s peaker units are inefficient, infrequently used, and aging—24 are over 40 years old. These features suggest that they may be good targets for replacement with energy storage and solar, demand response, and other clean alternatives. The siting of many of these units at larger plants, however, means that careful planning is required to ensure that energy storage replacements are not charged with high-emission resources (e.g. coal), which could inadvertently increase grid-wide emissions. Florida does not have policy targets supporting renewable energy or energy storage, but utilities in the state have begun to take advantage of the state’s significant solar resources by procuring large-scale solar and storage. These technologies can help displace high-emitting peaker plants on the grid. While Florida’s peaker units are located in both rural and urban areas, the latter tend to be located near minority and low-income populations which experience high levels of cumulative environmental, health, and socioeconomic burdens. Investments in distributed energy storage and clean energy resources in historically under-resourced communities near some of these plants have the potential to mitigate air pollution while providing resilience benefits to the surrounding community. Storage is currently most cost-competitive with peaker plants, but moving forward this approach can set a precedent for displacing fossil fuel power plants across the grid.

Technical Documentation: Look up data sources, methods, and a discussion of state-level policy and regulatory considerations. Florida Peaker Power Plant Mapping Tool: Explore and visualize peaker plant data for gas- and oil-burning power plants used statewide to meet peak electric demand, including data on operations, greenhouse gas and criteria pollutant emissions, and nearby population demographics. We include combustion turbine, steam, and internal combustion power plants as well as units at larger plants that are 5MW or larger and burn oil and gas at a low capacity factor—less than 15 percent. The data do NOT include nuclear, solar, wind, hydro, biomass, coal, natural gas combined cycle, or geothermal generation.

Florida Peakers: Statewide Map and Demographics
Explore a map of Florida’s peaker power plants in relation to demographic indicators. Hover or click on an individual plant on the map to pull up its data. Use filters to select measures such as Plant Name or Plant Unit Type. Note: Many of the units used to meet peak demand in Florida are located at larger natural gas or coal plants; if energy storage located at these facilities were charged by those or other coal or gas units, this could increase total emissions. Some plants report negative generation (they use more electricity on site than they produce) which results in negative values for certain indicators in the figure below. Example question: Which plants are located in urban, low-income or minority communities?
Cumulative Vulnerability Index
We developed a Cumulative Vulnerability Index to compare the socioeconomic, health, and environmental burdens on communities living near each power plant. This index is calculated by averaging the state percentiles of populations living near each plant for three health indicators, ten environmental indicators, and four demographic indicators, and then summing the scores for these three categories. If the population near a plant scored the median value on every indicator, its index score would be the reference value of 150. For full methods, see the technical documentation. Below, select a Distance from Plant of 1 or 3 miles to compare the populations living within this distance of each plant. Example question: Which plants are located in communities with high cumulative environmental, health and socioeconomic burdens?
Individual Plant Demographic View
Look up an individual Plant Name to find the demographics of populations living near the plant. Select a Radius of 1 or 3 miles to find average data for populations living within the chosen distance from the plant. Example question: What is the total population living within one mile of a plant?
Individual Plant Operational View
Look up an individual Plant Name to find information such as where the plant is located and the plant’s historical generation and emissions. Use the Year filter to find the average annual generation and emissions over the selected time period. Click on additional tabs to view a table or figure on its own. Example questions: How many times does a plant start per year? How many hours does it run when it is turned on? Plant start-up periods have higher emission rates, and 3-5 hours might be a good match for energy storage.
Plant Indicator Ranking
Hover below a column and click the ranking icon to re-rank the plants by a given environmental, demographic or operational indicator value. By default, plants are ranked by capacity (size). Use filters to select the Plant Unit Type and the Distance from Plant used to aggregate population data. By default, the columns are ranked by the plant size (capacity). Note: Some data, such as generation on poor air quality days, are missing for certain plants. Additional plants in Florida report negative generation (they consume more electricity on site than they produce) which plots as negative emission rates. Example question: Which plants have the highest emission rates of nitrogen oxides (NOₓ) for every megawatt-hour (MWh) of electricity generated? A MWh of an alternative resource would have the greatest emission benefits from displacing a MWh from one of these plants.
Data Comparison View
Choose which datasets to compare to create your own plot. Select X-Axis Selector and Y-Axis Selector to choose two datasets to compare. Use the Distance from Plant filter to select population in a 1- or 3-mile distance from the plant. Note: Some data, such as run times, are missing for certain plants. In this case, individual plants without data will not show up under search bar. Additional plants in Florida report negative generation (they consume more electricity on site than they produce) which plots as negative emission rates. Example question: Which plants are old and have low capacity factors? These might be good candidates for replacement.
