AEA Proposal •Purpose is to provide funding assistance to utilities for projects that expand utility-scale wind power in rural Alaska •Eligibility: certified electrical utilities and independent power producers •Proposals due Sept 15th, 2010 Renewable Energy Fund Grant Application Round IV Nushagak Community Wind Power Proposal •Two 200-300 kW wind turbines (ex. Aeronautica 29) •Produce 900 mega watt hours annually •Serve as an important educational tool for the community to gain the important skills and expertise for operating and maintaining state of the art renewable technology. •Such knowledge is a central component to Dillingham developing a sustainable energy system that integrated renewable power sources with existing diesel technology.
