Kahului is a diesel power plant located in Kahului, Hawaii, United States, with a capacity of 34 megawatts. Owned and operated by Maui Electric Co Ltd, the facility plays a role in the local power grid, providing electricity to the island of Maui. As an oil-fired plant, it operates within the context of Hawaii's energy landscape, which includes a mix of fossil fuels and renewable sources. The plant uses diesel technology, which is common for smaller-scale or peaking power plants due to its ability to start and stop quickly. With a capacity of 34 MW, Kahului falls into the small-to-medium scale for power generation in the United States. The facility is subject to federal and state environmental regulations, including the Clean Air Act, which governs emissions of pollutants such as SOx, NOx, and particulate matter from stationary sources. Kahului contributes to the reliability of Maui's electricity supply, supporting residential, commercial, and industrial customers. Its operation is integrated with other generation sources on the island, and it may serve as a backup or peaking plant. The facility's environmental footprint is managed through compliance with applicable emission standards and permits, reflecting the balance between energy needs and environmental stewardship.
Environmental context
Kahului's oil-fired diesel generation produces CO2, SOx, NOx, and particulate emissions, contributing to local air quality considerations. Located in Kahului, a populated area on Maui, the plant's emissions are regulated under the Clean Air Act and state air permits. The facility's age and technology (diesel) influence its efficiency and emission profile, with potential for higher emissions per MWh compared to modern combined-cycle plants. Proximity to residential areas may require additional controls to meet ambient air quality standards.
