3rd Avenue Substation - Tampa, Florida Electrical Substation

3rd Avenue Substation is an electrical substation located in Tampa, Florida, United States. Owned and operated by TECO, the facility is currently operational and plays a role in the regional power distribution network. The substation handles voltage levels of 69 kV and 13 kV, indicating its function in stepping down transmission-level power for local distribution. As part of the U.S. electrical infrastructure, this substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). TECO, as a utility, adheres to NERC reliability standards to ensure grid stability. The substation's voltage levels suggest it serves as a distribution substation, connecting the transmission grid to lower-voltage distribution lines serving residential and commercial customers in the Tampa area. The substation's location in Tampa places it within a growing urban environment with increasing electricity demand. Its role in the local grid is critical for maintaining reliable power supply to the community. The facility's operational status and integration with TECO's network contribute to the overall resilience of the regional electrical infrastructure.

The substation is situated in an urban area of Tampa, Florida, where the local environment is characterized by a subtropical climate with high humidity and frequent thunderstorms. Electrical infrastructure in such regions must be designed to withstand weather-related stresses, including lightning strikes and heavy rainfall. The substation's equipment, such as switchgear and transformers, is typically housed in weatherproof enclosures to ensure reliability. The urban setting also means the substation is subject to local land-use regulations and community considerations regarding noise and visual impact.
