In 2010, the community of Kokhanok, Alaska, installed two 90-kW wind turbines, battery storage, a converter, and equipment for integration. Researchers at the National Renewable Energy Laboratory performed an analysis and modeling using the HOMER and REopt software modeling packages.The analysis was designed to answer the following questions: 1) What is required to achieve a 50 percent reduction in power plant diesel fuel consumption in a diesel microgrid? 2) What is required to achieve a 50 percent reduction in 'total' (diesel and heating oil) consumption in a remote community? 3) What is the impact and role of energy efficiency? This presentation provides an introduction to the community of Kokhanok, Alaska; a summary of energy data; and an overview of analysis results and conceptual design.
