Hawaii Pacific GIS Conference 2012: Natural Resource Management - Assessing Hydroelectric Power Potential in the State of Hawaii using GIS
Assessing Hawaii’s Hydropower Development Potential: Conventional and Ocean Energy Alternatives Hawaii Pacific GIS Conference 2012 Honolulu Convention Center, March 5th 2012
Study Purpose and Overview 1● State-Wide Assessment (Reconnaissance Level)● Partners: USACE Honolulu District (Deborah Solis, PM) Dept. of Business Economic Development and Tourism (DBEDT) EA Engineering + Helber Hastert & Fee Planners Joint Venture Hawaii National Marine Renewable Energy Center at UH● Initiated in 2009 100% Federally funded● Tool for developers & decision makers
History of Traditional Hydro in Hawaii 2- Most geographically remote major island chain in the world - Long history of traditionalhydro in Hawaii - Sugar mills - Ditch systems Photos: Wilcox (1998)
Current Energy Portfolio 3 HYDRO● Most fossil fuel dependent state in the nation● 90% of energy BIOMASS needs supplied by imported oil COAL● Spend as much as $7 billion PETROLEUM annually outside the islands to meet energy needs
Project Elements – Traditional Hydro 4Update 1981 report and provide ‘snapshot’ ofhydroelectric power in HawaiiDesktop review of traditional hydro plants: - Presently operating - Once operational - Proposed in the past but never built
Screening Criteria - Hydropower 5Environmental Endangered Species/Critical Habitat Conservation DistrictsEconomic Commercial/tourism use Capacity Calculated Incremental Energy Cost Accessibility/transmission linesSocial Cultural Impacts Water Sports Recreational useFederal Interest
