Hawaii Pacific GIS Conference 2012: Natural Resource Management - Assessing Hydroelectric Power Potential in the State of Hawaii using GIS
1. Assessing Hawaii’s Hydropower Development Potential:
Conventional and Ocean Energy Alternatives
Hawaii Pacific GIS Conference 2012
Honolulu Convention Center, March 5th 2012
2. 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
3. History of Traditional Hydro in Hawaii 2
- Most geographically remote
major island chain in the
world
- Long history of traditional
hydro in Hawaii
- Sugar mills
- Ditch systems
Photos: Wilcox (1998)
4. 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
5. Project Elements – Traditional Hydro 4
Update 1981 report and provide ‘snapshot’ of
hydroelectric power in Hawaii
Desktop review of traditional hydro plants:
- Presently operating
- Once operational
- Proposed in the past but never built

14. Project Elements – Ocean Energy 13
• General review of
resource potential for
ocean energy in
Hawaii
• 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
