Coolodge Substation - Vermont Electric Power Company Electrical Substation

Coolodge Substation is an operational electrical substation located in Vermont, United States, owned and operated by Vermont Electric Power Company (VELCO). The facility handles high-voltage transmission at 345 kV and 115 kV, positioning it as a key node in Vermont's bulk power system. As part of VELCO's network, it supports the integration of renewable energy sources and ensures reliable electricity delivery across the region. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for transmission-level assets. With voltage levels typical of major transmission substations, Coolodge Substation is equipped with modern switchgear and automation systems, likely adhering to ISO/IEC 61850 standards for substation automation. Its location in rural Vermont aligns with the state's focus on grid modernization and resilience against extreme weather events. Coolodge Substation plays a critical role in maintaining grid stability for central Vermont, serving both urban and rural communities. As part of VELCO's transmission infrastructure, it facilitates the flow of electricity from generation sources to distribution networks, supporting the state's goal of 100% renewable energy by 2030. The substation's operational status and voltage capacity underscore its importance in the regional electrical infrastructure.

Coolodge Substation is situated in a rural area of Vermont, a state known for its mountainous terrain and forested landscapes. The substation's high-voltage equipment is designed to withstand harsh winter conditions, including snow and ice accumulation, which are common in the region. Its location away from densely populated areas reduces potential electromagnetic field exposure, while the surrounding environment supports biodiversity. The substation's role in integrating renewable energy sources, such as wind and solar, contributes to Vermont's low-carbon electricity grid.
