The legislative assembly establishes a state renewable and recycled energy objective that ten percent of all electricity sold at retail within the state by the year 2015 be obtained from renewable energy and recycled energy sources. The objective must be measured by qualifying megawatt-hours delivered at retail or by certificates representing credits purchased and retired to offset nonqualifying retail sales. This objective is voluntary and there is no penalty or sanction for a retail provider of electricity that fails to meet this objective. The objective applies to all retail providers of electricity in the state, regardless of the ownership status of the electricity retailer. Municipal and cooperative utilities that receive wholesale electricity through a municipal power agency or generation and transmission cooperative may aggregate their renewable and recycled energy objective resources to meet this objective.
