Greendale Substation - 115 kV Electrical Substation in the United States

Greendale Substation is an operational electrical substation located in the United States, owned and operated by National Grid. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution and sub-transmission networks. As part of National Grid's infrastructure, it plays a role in delivering electricity to local communities and industries. The substation's technical specifications indicate a 115 kV voltage level, which is common for substations that step down power from higher transmission voltages for local distribution. In the United States, such facilities are subject to NERC reliability standards and FERC regulations to ensure grid stability and safety. The substation likely includes switchgear, transformers, and protection systems compliant with industry standards. Operationally, Greendale Substation contributes to the reliability of the regional electrical grid. Its location in a populated area underscores its importance in meeting local energy demands. The facility's age and specific equipment details are not disclosed, but its operational status confirms ongoing maintenance and regulatory compliance.

The substation's location in a developed area means its environmental impact is primarily related to electromagnetic fields and land use. Substations of this voltage typically have a small footprint and are designed to minimize visual and noise impacts. The surrounding environment may include residential or commercial zones, requiring adherence to local zoning and environmental regulations.
