Hatwai Substation: High-Voltage Electrical Substation in the United States

Hatwai Substation is an operational electrical substation located in the United States, with coordinates 46.469230, -116.910354. The facility operates at high voltage levels of 500,000 volts and 230,000 volts, indicating its role in bulk power transmission and distribution. As a substation, it serves as a critical node in the electrical infrastructure, stepping down voltage for local distribution or interconnecting transmission lines. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards and FERC oversight for transmission-level assets. The voltage levels suggest it is a major transmission substation, likely part of the interconnected grid managed by a regional transmission organization (RTO) or independent system operator (ISO). Such facilities are essential for maintaining grid stability and ensuring reliable electricity supply to residential, commercial, and industrial consumers. Hatwai Substation's location in the Pacific Northwest region places it within a grid that integrates hydropower, wind, and other renewable energy sources. The substation's operational status and high voltage capacity underscore its importance in supporting the region's energy needs and facilitating the integration of diverse generation sources. Its role in the electrical infrastructure contributes to the overall resilience and efficiency of the power system.

The substation's location in the Pacific Northwest is characterized by a mix of mountainous terrain and agricultural valleys, with a climate that includes wet winters and dry summers. The high-voltage equipment is designed to withstand local weather conditions, including potential ice storms and wind events. The facility's operation supports the integration of renewable energy sources like hydropower and wind, which are prevalent in the region, thereby contributing to reduced greenhouse gas emissions compared to fossil fuel-based generation.
