TECO Energy Inc. operates as an energy holding enterprise headquartered in Tampa, Florida, functioning as a subsidiary under Emera Incorporated. Its portfolio includes Tampa Electric, which provides electricity to the Tampa Bay Area and regions of Central Florida; Peoples Gas Company, recognized as Florida’s largest natural gas distributor; and TECO Services, delivering support in IT, human resources, legal matters, and facilities management. Formerly part of the S&P 500 index, TECO Energy transitioned to private ownership following its acquisition by Emera.

Tampa Electric ranks among Florida’s most prominent investor-owned electric utilities, catering to more than 830,000 customers throughout West Central Florida. Peoples Gas System Inc. supplies natural gas to close to 470,000 residential and commercial clients across the state.

History

Established in 1899 by Colonel Peter O. Knight to address Tampa’s increasing demand for energy, Tampa Electric Company initiated operations with its first steam power plant in 1903 and introduced its initial turbo-generator by 1906. The company experienced rapid growth by promoting electric amenities and constructing extensive service networks linking Tampa with neighboring communities.

By 1914, the company inaugurated modern office facilities downtown. By the end of the twentieth century, Tampa Electric and TECO Energy collectively employed over 5,000 personnel spanning six states and territories in South America.

On September 4, 2015, Emera, a utility holding firm based in Halifax, declared its intention to acquire TECO Energy. This transaction was finalized on July 1, 2016, resulting in TECO becoming a wholly owned subsidiary of Emera.

Environmental record

In late 2021, Tampa Electric unveiled its commitment to reach net zero carbon emissions by the year 2050. The utility intends to broaden its use of zero- and low-carbon technologies by investing in innovative approaches such as carbon capture methods, biofuels, hydrogen energy, wind power installations, and battery storage systems. It will also trial renewable energy distribution at the community level and maintain partnerships with the University of South Florida to foster technological advancements aligned with its net zero ambitions.

Additionally, Tampa Electric is upgrading existing facilities to enhance fuel efficiency and reduce pollutant outputs, including converting Big Bend’s Unit 1 into a combined-cycle unit fueled by natural gas. These improvements aim to decrease emissions while optimizing fuel expenses for consumers. In 2022, the company contributed $5 million toward USF’s Clean Energy Research Center to advance its sustainability objectives.

Historically, TECO Energy was ranked in 2006 as the thirty-seventh-largest corporate source of air pollution within the United States, emitting approximately 11 million pounds of hazardous substances annually as of 2002. Key contaminants released included hydrochloric acid, sulfuric acid, chromium compounds, arsenic, and nickel-based pollutants. In 2000, TECO incurred a $3.5 million penalty for altering emission-producing equipment without implementing updated pollution control technologies. This violation spurred a transition from coal reliance toward natural gas usage alongside enhanced emission reduction strategies targeting sulfur dioxide and nitrogen oxide outputs.

On July 6, 2019, People's Gas—a division of Tampa Electric—was implicated in legal claims concerning a gas explosion at Plantation’s Market on University shopping center. Lawsuits alleged failure to properly close and secure a gas line following a customer request in December 2018—actions that contravened federal and state regulations. TECO attributed the problem to a software malfunction that canceled hundreds of shutoff commands across its system and partly faulted the shopping center owner for not capping the gas line after tenant equipment removal. More than sixty lawsuits were filed subsequently, many remaining unresolved.

In 2017, an explosion at TECO’s Big Bend power station resulted in five fatalities during maintenance work on a coal-fired furnace. Despite having safety protocols established after a similar incident ten years prior, TECO reportedly did not provide sufficient worker training. In May 2022, TECO admitted guilt for breaching OSHA safety standards related to employee training deficiencies. By August 2022, the company faced a $500,000 fine and was placed on probation for three years following acknowledgment of willful safety violations.
