Kaua’i Island Utility Cooperative Renewable Energy Technology Assessments 6.0 Renewable Energy Financial Incentives Table 6-4. Renewable Energy Incentives Summary. Incentive Description Recommendation Misc. Loan & Grant Programs Green Power Purchasing Goal Miscellaneous grants for development of renewable energy projects. Monitor for potential grant opportunities. Goal for federal government facilities to purchase 2.5 percent of electricity from renewable sources by 2005, and 20,000 solar roofs by 2010. Non-Government Incentives Green Pricing Voluntary program where utility customers pay premium for renewable electricity. Regulated markets. Green Marketing Renewable Energy Credits Voluntary program where electricity customers pay premium for renewable electricity. Deregulated markets. Tradable credits representing the renewable attributes of electricity – separate from the actual energy. May be used to satisfy voluntary programs or renewable portfolio standard requirements. Contact military base and government facilities managers regarding joint development or purchase of renewable energy. Consider developing program to test customer demand. Not applicable to Hawaii. Evaluate as a flexible mechanism to meet RPS requirements, or sell excess credits to other Hawaii utilities. 21 March 2005 6-2 Black & Veatch
Kaua’i Island Utility Cooperative Renewable Energy Technology Assessments 7.0 Biomass and Municipal Solid Waste 7.0 Biomass and Municipal Solid Waste Biomass and waste-to-energy (WTE) power plants use substantially similar technologies. In the case of Kauai, it is possible that the best economies of scale for a solid fuel combustion project will occur by combining the two fuels in a common project. This is not typical in most locations, but constrained fuel resources make this a reasonable option to consider. This section, therefore, will combine the two fuels and technologies with alternately separate and combined discussion of plant configurations, as appropriate. 7.1 Basis for Assessment The Interim Report identified typical biomass and WTE generation technologies. The understanding and basis for these characterizations come from Black & Veatch’s extensive history of designing and constructing these plants. This section presents multiple options for biomass or WTE plants. Determining which best suits KIUC’s needs is a matter of understanding plant performance and cost, economies of scale, fuel supply, and operation and maintenance requirements. These issues can be resolved into the following questions: • On a busbar cost basis, is it better to build a small plant burning low cost residue; or a larger, more efficient plant burning more expensive fuel? • What are the options for combining biomass and WTE fuels in terms of common plant facilities? These questions will be answered in the Project Options Screening, and the preferred sizes and configurations will be characterized in the remainder of the section. Based on our design experience, we have made several assumptions regarding plant performance. These are the following: Table 7-1. Biomass and WTE Plant Performance Assumptions.
