Appleway Substation: Avista 115 kV Substation in the United States

Appleway Substation is an operational electrical substation located in the United States, operated by Avista. The facility operates at a voltage of 115 kV, placing it in the medium-to-high voltage range typical for distribution and sub-transmission substations. As part of Avista's network, it plays a role in delivering electricity to customers in 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 set reliability standards for the bulk power system. In the United States, substations like Appleway are subject to NERC's Critical Infrastructure Protection (CIP) standards, ensuring cybersecurity and physical security. The 115 kV voltage level is common for local distribution and industrial supply. Appleway Substation contributes to grid stability and reliability in its service area. As part of Avista's infrastructure, it supports the delivery of electricity to residential, commercial, and industrial customers. The facility's operational status ensures continued power supply, and its location in the Pacific Northwest aligns with the region's hydroelectric-dominated generation mix.

The substation is located in the Pacific Northwest, a region with significant hydroelectric power generation. The local environment includes mixed urban and rural areas, with proximity to natural habitats. Substations at this voltage level typically have minimal direct environmental impact, though they are part of the broader grid infrastructure that supports renewable energy integration and load balancing.
