The Nanpil River Hydropower Project is a 1600 KW run-of-the-river hydropower project located on the tropical island of Pohnpei, Federated States of Micronesia. The hydropower project will consist of an intake located at an existing water supply dam, a 4,600-foot penstock buried under the access roadway, a powerhouse, a switchyard, and a 2-mile transmission line. The construction contract includes one year of contractor operation and maintenance, with the simultaneous training of local operators. The US Army Corps of Engineers planned and designed the hydropower facility on a reimbursable basis for the State of Pohnpei. Interesting design challenges included assessing environmental impacts and designing the facilities for a minimum of operation and maintenance requirements.
