Polk Power Station is an operating power station of at least 1166-megawatts (MW) in Mulberry, Florida, United States with multiple units, some of which are not currently operating.

Table 2: Unit-level details
| Unit name | Status | Fuel(s) | Capacity (MW) | Technology | CHP | Start year |
|---|---|---|---|---|---|---|
| CC2 | Operating[1] | fossil gas: natural gas, fossil liquids: diesel[1][2] | 1166[1] | combined cycle[1][2] | no[1] | 2017[1] |
| Unit 1 | Mothballed | coal: unknown, fossil gas: natural gas, fossil liquids: fuel oil | 192.9 | IGCC | – | 1986 |
CHP is an abbreviation for Combined Heat and Power. It is a technology that produces electricity and thermal energy at high efficiencies. Coal units track this information in the Captive Use section when known.

Demonstration plant
In 2010 TECO said it was partnering with RTI International and the Shaw Group to conduct a study on a technology to "clean" synthetic gas (syngas) of sulfur dioxide at elevated temperatures. The study will evaluate the construction of a pilot project to demonstrate the technology on a 30 percent side stream at the Polk IGCC plant.[3]
Gas-Fired Generation
The power station has an installed capacity of 1,492.5 MW[4] between two combined-cycle units. Unit 1 is a one-on-one dual-fuel combined cycle unit capable of burning natural gas or solid fuel through the IGCC process. According to the Tampa Electric's website, the company has placed the IGCC process in long-term reserve standby while utilizing natural gas as the most cost-effective fuel to produce power and reduce costs to their customers[5]. However, the unit is still listed as using the IGCC technology on the website of the Florida Department of Environmental Protection[6].
Unit 2 is a four-on-one natural gas combined cycle unit constructed in 2017 by converting four simple cycle combustion turbines into a modern, efficient combined cycle facility. Two of the four combustion turbines are dual fuel using natural gas and ULSD (Ultra-Low Sulfur Diesel) oil[5].
Carbon Capture and Storage Project
In August 2022, the agency’s Office of Fossil Energy and Carbon Management (FECM) announced $31 million in funding for 10 CCS projects, including front-end engineering design (FEED) study completion for carbon capture systems at the Polk power station[7]. The project would add ION Clean Energy, Inc's CCS technology at the plant. It plans to capture at least 95% of CO2 emissions equating to nearly 3.7 tonnes per year to be stored in geological deposits[8].

Death and disease attributable to fine particle pollution from the Polk Power Station
In 2010, Abt Associates issued a study commissioned by the Clean Air Task Force, a nonprofit research and advocacy organization, quantifying the deaths and other health effects attributable to fine particle pollution from coal-fired power plants.[9] The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma-related episodes and asthma-related emergency room visits, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, peneumonia each year are attributable to fine particle pollution from U.S. coal-fired power plants. Fine particle pollution is formed from a combination of soot, acid droplets, and heavy metals formed from sulfur dioxide, nitrogen oxide, and soot. Among those particles, the most dangerous are the smallest (smaller than 2.5 microns), which are so tiny that they can evade the lung's natural defenses, enter the bloodstream, and be transported to vital organs. Impacts are especially severe among the elderly, children, and those with respiratory disease. Low-income and minority populations are disproportionately impacted as well, due to the tendency of companies to avoid locating power plants upwind of affluent communities.
The table below estimates the death and illness attributable to the Polk Power Station. Abt assigned a value of $7,300,000 to each 2010 mortality, based on a range of government and private studies. Valuations of illnesses ranged from $52 for an asthma episode to $440,000 for a case of chronic bronchitis.[10]
Table 1: Death and disease attributable to fine particle pollution from the Polk Power Station
| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 1 | $6,200,000 |
| Heart attacks | 1 | $120,000 |
| Asthma attacks | 11 | <$1,000 |
| Hospital admissions | <1 | $15,000 |
| Chronic bronchitis | <1 | $210,000 |
| Asthma ER visits | 1 | <$1,000 |
