Overview
Key West Substation is an operational electrical substation in Key West, Florida, United States. It operates at 138 kV and is owned by KEYS, serving the local grid.
Key West Substation is an operational electrical substation located in Key West, Florida, United States. It is owned by KEYS and operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for distribution and sub-transmission substations. The facility plays a key role in the local electrical infrastructure, supporting the power needs of the Key West area. As a substation operating under the jurisdiction of the United States, it is subject to NERC reliability standards and FERC regulation for transmission-level assets. The 138 kV voltage level is common for regional power distribution, connecting higher-voltage transmission lines to lower-voltage distribution networks. The substation's equipment likely includes switchgear, transformers, and protection systems compliant with industry standards such as IEEE and ISO/IEC 61850 for substation automation. The substation is situated in a coastal urban environment, which presents specific operational considerations such as exposure to saltwater corrosion and hurricane risks. Its role in the grid is critical for maintaining reliable electricity supply to Key West, a populated island city. Ongoing maintenance and upgrades are typical for ensuring grid stability in such a location.
Environmental context
Located in the coastal city of Key West, Florida, the substation operates in a marine environment with high humidity and salt exposure, which can accelerate corrosion of electrical equipment. The area is also prone to hurricanes and tropical storms, requiring robust infrastructure resilience measures. The substation's urban setting means it supports a dense population and tourism-dependent economy, making grid reliability a priority. Environmental considerations include stormwater management and potential impacts on local ecosystems, though specific designations are not confirmed.
Frequently asked questions
Key West Substation is located in Key West, Florida, United States, at coordinates 24.575669, -81.734182.
Key West Substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution substations in the United States.
