Transcript of Hawaii Pacific GIS Conference 2012: Natural Resource Management - Assessing Hydroelectric Power...
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 ● 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
1
History of Traditional Hydro in Hawaii
- Most geographically remote major island chain in the world
2
- Long history of traditional
hydro in Hawaii
- Sugar mills
- Ditch systems
Photos: Wilcox (1998)
Current Energy Portfolio
● Most fossil fuel dependent state in the nation
● 90% of energy needs supplied by imported oil
● Spend as much as $7 billion annually outside the islands to meet energy needs

• General review of
resource potential for
ocean energy in
Hawaii
Project Elements – Ocean Energy
• Consideration of
opportunities and
constraints in a
spatially explicit
context (e.g. low-level
marine spatial
planning)
• Hawaii is already a
leader in ocean
energy R&D
