Overview
Saint Helens Substation is an operational electrical substation in the United States, owned and operated by Clark Public Utilities. It operates at a voltage of 115 kV, serving the grid stability needs of the region.
Saint Helens Substation is an operational electrical substation located in the United States, owned and operated by Clark Public Utilities. The facility operates at a voltage of 115 kV, placing it within the sub-transmission voltage class typical for regional distribution networks. As a substation, it plays a critical role in stepping down transmission-level voltages for local distribution or interconnecting generation sources. 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 bulk power systems. Clark Public Utilities, a public utility serving Clark County, Washington, manages this asset as part of its electrical infrastructure portfolio. The 115 kV voltage level is common for sub-transmission systems that supply industrial and residential loads. Environmentally, the substation is situated in an urbanized area near the Columbia River, supporting the electrical needs of the surrounding community. Its operational status ensures grid reliability and voltage regulation, contributing to the stability of the regional power system. The facility's location in a densely populated area underscores its importance for local energy distribution and emergency response capabilities.
Environmental context
The substation is located in an urbanized area near the Columbia River, where it supports the electrical needs of residential, commercial, and industrial users. Its 115 kV voltage level is typical for sub-transmission systems that balance grid stability with local distribution demands. The facility's operation contributes to regional energy reliability, particularly during peak demand periods or extreme weather events common in the Pacific Northwest.
