Overview
Kawaihae Substation is an operational electrical substation in Hawaii, United States, owned by Hawaiian Electric Company. It operates at voltages of 69 kV and 12.47 kV, serving the local grid.
Kawaihae Substation is an operational electrical substation located in Hawaii, United States. Owned and operated by Hawaiian Electric Company, this facility plays a key role in the state's electrical infrastructure, stepping down transmission voltages for local distribution. The substation operates at two voltage levels: 69 kV for transmission and 12.47 kV for distribution, typical of medium-voltage substations in the US. As part of the Hawaiian Electric grid, it is subject to NERC reliability standards and FERC regulation, ensuring stable power delivery to the region. Located on the Big Island's Kohala coast, the substation supports the local community by facilitating electricity distribution. Its coastal location requires resilience against tropical weather and salt spray, common challenges for Hawaiian infrastructure. The facility contributes to grid stability in a region with growing renewable energy integration.
Environmental context
Located on the Big Island's Kohala coast, Kawaihae Substation operates in a tropical marine environment. The substation's coastal proximity exposes it to salt spray and high humidity, which can accelerate corrosion of electrical equipment. The area is also prone to tropical storms and volcanic activity, requiring robust infrastructure design. The substation supports the local grid, which increasingly integrates renewable energy sources like wind and solar.
