Page 2 Kaua’i Island Utility Cooperative B&V Project 137174 Renewable Energy Technology Assessments 21 March 2005 - Added page references to list of technologies on page 1-2 4. Renewable Energy Technology Screening - Revised charts to clarify the MSW Mass Burn option 5. Project Characterizations - Capacity credit for hydro and wind changed to zero. This reduces the competitiveness of these two technologies relative to firm resources. - Note added that levelized cost calculations are performed in 2009$, the year assumed that all projects will come on-line. Previously evaluation assumed startup of all projects in 2005. This change impacted all project economic calculations, essentially escalating the previously reported 2005$ to 2009$. Although the costs increased somewhat, the relative rankings of projects remained essentially unchanged. 6. Renewable Energy Financial Incentives - Added updates and additions to several of the incentives (production tax credit, REPI, accelerated depreciation, etc.). - Added Section 6.2 – “Valuing Renewable Energy Attributes” discussing green pricing, renewable energy credits, etc. - Added new summary Section 6.3 7. Biomass and Municipal Solid Waste - Reduced capital cost of biomass and biomass/MSW combination plant by 5 percent. The previous report had double-counted some indirect costs. - Noted increase in estimated biomass cost between first and second phases of the study. 8. Hydro - Updated information provided for the Upper Lihue and Wailua projects. Revised Upper Lihue capital cost estimate and generation estimate based on latest information. 9. Wind - The capital costs for the Hanapepe and Anahola sites have been adjusted to account for higher site access costs (roads and transmission). This increases the levelized costs of these two sites. 10. Landfill gas - Added minor clarifications noting that (1) there is another small landfill on the island, but it is not technically feasible for LFG production, (2) the Kekaha site could be developed now (before completion of Phase II), if desired. However, no additional technical information is provided on these options. 11. Final Renewable Energy Project Scoring - Updated scoring based on changes in previous sections. MSW plant with high tipping fee is now the number one ranked project. 12. Conclusions - Updated conclusions based on changes in previous sections. No substantive changes from before. - Noted increase in estimated biomass cost between first and second phases of the study.
