Energy Efficiency & Renewable Energy

Proposed Wind & Water Power Program Alignment


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;


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


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


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


The renewable energy world is getting more complicated


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


Better resource estimates are needed


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.)


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
