The Role of Public-Private Partnerships in Advanced Turbine Development
Michael J. SaleConference on Environmentally Enhanced Hydropower Turbines
Washington, DC, May 19, 2011
Hydropower is a well-established industry
Slide 2
• Clean, renewable energy since 1901• ~2000 operating power plants in U.S.• ~280 TWh average annual generation
Even “mature” technology changes• What hasn’t changed
– Power equation:
P = k * H * Q– Turbomachinery options
• What has changed– Environmental demands
• Fish passage• Instream flows• Water quality
– Competition• Other uses of water• Alternative energy sources• ROI expectations
Slide 3
There is a lot of old equipment out there.

Slide 5
Opportunities exist for significant additional generation:
New Opportunities in Hydropower
1) Improvements at existing power plants:• Efficiency upgrades• Capacity upgrades
2) Development of non-powered dams
3) Small hydropower (< 5 MW):• Low-head dams or
conveyance structures• New sites (waterfalls or
diversions)• Water distribution systems
4) Pumped-storage hydropower
Multiple forces drive technology development

Advanced Hydropower Turbine Systems Program
• 1992 Kansas City R&D Forum started new thinking
• February 1994 meeting of DOE, EPRI, and NHA led to formation of AHSTP
• Industry collected $500K and asked DOE to match it
• Hydro Research Foundation formed to manage industry funding
• Steering and Technical committees established for management and oversight

Example of partnerships
First, focus on conceptual designs• DOE solicitation to study new turbines with improved
performance issued in October 1994– Variable speed/pitch runners and generators– Self-aerating turbines– Innovative, cost-effective fish passage technologies– Durable, lightweight, cavitation-resistant materials
• Two teams selected competitively; 1995 awards to:– Harza-Voith-TVA-Normandeau-GaTech focused on modifications to
traditional Kaplan and Francis machines– Alden-NREC focused on a new, innovative design
• Final reports completed 1997– Voith Hydro Inc., Rpt. No. 2677-0141– ARL, Inc. and NREC, ARL Rpt. No. 13-97/M63F, DOE/ID-10571– Summary report, Odeh 1999, DOE/ID-13741
• Supporting R&D at DOE Labs on Design Biocriteria
AHTSP Phase I
Second, build and test fully engineered prototype models
• Testing of Alden-NREC design was needed with fish to validate concept
• Closed-loop test facility constructed at Alden Research Lab, along with prototype runner– Design report, Sept. 2000– Full operation, Sept. 2001
• Fish survival for multiple species, measured under controlled conditions, with and without wicket gates
• Active Technical Committee direction and oversight
AHTSP Phase II
Changes in fixed-bladed reaction turbines
Slide 10
Third, build and test full-scale turbines in the field
• Competitive solicitation in two steps:– Notice of Interest for
technologies to study– RFP for sites to apply them
new technology• Three financial assistance
agreements, September 2002:– Osage Project, AmerenUE– Priest Rapids Project
(Wanapum Dam), Grant Co. PUD
– Box Canyon, Pend Oreille PUD
• Additional joint-funded work with Corps of Engineers via Interagency Agreement

AHTSP Phase III
Slide 12
Investments will dictate Hydropower’s future
• Equipment will have to be replaced eventually– What will it be replace with?– Win-win possibilities strongest with Best Available
Technology
• We have proven that innovation is possible in conventional hydropower (AHTSP and others)
• Both public and private investments are critical for successful technology development
• Looming federal budget problems mean that partnerships of all types will be more important than ever
