Energy Efficiency & Renewable Energy
Water power R&D was restored in FY 2008
• DOE directed to establish marine and hydrokinetic technology program
• $10 million in FY08 to address advanced water power technologies (including conventional hydro)
• The majority of ’08 funds will be distributed to industry, academia and others via competitive solicitations
• $3 million requested for ’09
• ’09 House mark $40m;
Energy Efficiency & Renewable Energy
Program priorities are driven by EISA language this year
Reestablish effective Water Power Program
Marine and Hydrokinetics
• Understand the full-range of technologies and their performance characteristics
• Investigate potential environmental impacts and how they can be mitigated or minimized
• Reduce costs and improve performance through technology development and testing Develop National Marine Energy RD&D Centers
• Work with industry leaders to develop international standards
• Encourage information-sharing within government, regulators and the industry
Conventional Hydropower
• Increase turbine efficiency
• Improve environmental performance
Energy Efficiency & Renewable Energy
Competitive solicitation is the major FY2008 activity
• Three primary areas:
– Cost-share agreements with industry partners to improve technologies and reduce manufacturing and operational costs via technology development and testing
– Grants or cost-shares to industry experts to address marine and hydrokinetic resource assessments, environmental concerns, interconnection requirements, and other barriers to development and deployment
– Cost-share agreements with one or more universities or university-led consortia to help develop marine technology RD&D centers
• Proposals due June 16; awards to be announced in August
Energy Efficiency & Renewable Energy
Other FY2008 activities are underway• Report on environmental impacts
(as directed by EISA 2007 -- Sec 633 b)
• Identification and comparison of existing marine and hydrokinetic technologies
• International collaboration and standards development (IEA, IEC)
• Inter-agency collaboration
• Competitive Research and Development Agreements
• Industry/stakeholder collaboration

Water Use Optimization is a growth area for hydropower
• WUOW help August 2004 in Hood River, OR– 20 participants representing
industry, agencies, and environmental NGOs
– Draft report completed and circulated for comment
• Need for more federal R&D investment was confirmed
• Future Directions:– Draft Implementation Plan and
Peer Review by Spring 2005– SOS Review by September
2005
Four types of hydropower optimization were identified
Type 1:Individual machines
Type 2:Single dam with
multiple powerplants
Type 3:River basin with
multiple dams
Type 4: Hetergenous power

Examples of constraints Modeling (and scheduling/planning) components
Energy Efficiency & Renewable Energy
Time scales and planning horizon vary
• Modeling across time scales
– Aligning energy, water, and ecological model timing
– Transferring energy, mass balance, and other constraints between nested models,
• Resolving events and processes—examples:
– Reproduction, mortality, growth
– Drought, floods, climate change
– Reservoir stratification and turnover
– Peak energy and ancillary services valuation
Energy Efficiency & Renewable Energy
Hydrometeorology is critical to water power development
Needs/requirements• Maximum precipitation and
flows (e.g., for dam safety)• In-channel velocity distribution• Short, mid, and longer-term
forecasts of flows, including climate change
• Magnitude and duration of river flows, wave height, and tidal currents
• Demonstrations of new data and tools
Challenges/gaps• Educate industry on available
tools and demonstrate use• Resource data at appropriate
scales for energy development• Tools for integrated power
systems (wind-hydro integration)
• Incorporation of environmental quality variables into power system optimization (flows, temperature, habitat, etc.)
Energy Efficiency & Renewable Energy
Industry conferences are good for technology transfer
For example, Climate & Hydro Symposium at Waterpower XV, July 2007– Session 6A – Science and Products
• Dale Kaiser – CDIAC, Oak Ridge National Laboratory• Arun Kumar – CPC/NCEP, NOAA• John Schaake – National Weather Service (retired), Office of
Hydrology
– Session 6B – Applications• Rolf Olson, CREEL, Corps of Engineers• Ed Bruce, Duke Energy• Luis Melendez, EDELCA, Venezuela
