India’s National Hydroelectric Power Corp. (NHPC) reports it fully commissioned the 390-mw Dulhasti hydroelectric project on the Chandra River in Jammu and Kashmir State.
NHPC said the project’s third unit was synchronized to the transmission grid March 26. The first two units were synchronized February 28 and March 18.
The run-of-river project was built in the Middle Himalaya Mountains by Jaiprakash Associates Ltd. (JAL), a unit of the Jaypee Group. It has a 65-meter-tall, 186-meter-long concrete gravity dam, 10.5-kilometer headrace tunnel, 298-meter tailrace tunnel, and an underground powerhouse containing three 130-mw turbine-generators.
Although work initially began in 1989 under a French consortium, civil construction was suspended in 1992, with the partially completed works taken over by NHPC. The company awarded a completion contract to JAL in 1997. In 1998, the government committed to fully fund Dulhasti.
A setback occurred in January when a tunnel collapsed, killing two workers, injuring 13, and flooding the Kishtwar area.

IN MEMORIAM: Veltrop remembered for contributions to dams, hydropower community
Jan Veltrop, an engineer whose contributions to the global dam community included a term as president of the International Commission on Large Dams (ICOLD), died March 24. He was 85.
Veltrop, a leading international authority on dam design, joined Harza Engineering Co. in Chicago, now MWH, in 1954. From 1979 to 1984, he was Harza’s chief engineer. He retired from the consulting engineering firm in 1994 as senior vice president.
Veltrop was a prolific writer, author of more than 70 technical papers and articles while at Harza. During that time, he also guided project planning, design, construction, and monitoring of dams, including their environmental and social aspects. Veltrop worked on projects throughout the world.
He directed the design of the Mayfield and Mossyrock dams in the United States, both part of Tacoma Power’s 462-mw Cowlitz River project, in Washington, and the Karadj and Karun 1 dams in Iran. As project manager and director, Veltrop led the development of the Tachien hydroelectric project in Taiwan, Mangla spillway in Pakistan, Karun 1 hydro project in Iran, and 2,316-mw Bath County Pumped-Storage project in the U.S.
Veltrop also worked on the 3,478-mw Tarbela project in Pakistan and 10,300-mw Guri (Simon Bolivar) project in Venezuela. For a year and a half in the 1980s, he was resident manager in Chengdu, China, for the preparation of contract documents for international bidding for the 3,300-mw Ertan hydroelectric project. In the 1990s, he was based in Haifa, Israel, as project manager for a proposed pumped-storage project near the Dead Sea.
In the early 1980s, Veltrop served a two-year term as chairman of the U.S. Committee on Large Dams. In 1988, he began a three-year term as president of ICOLD.

DEVELOPMENT: Austria utility to build 350-mw Reisseck 2
Austria utility Verbund announced plans in March to build the 350-mw Reisseck 2 pumped-storage project.
Verbund General Director Hans Haider said the project represents an investment of about 215 million euros (US$287 million) and 3,000 person-years of employment. Verbund’s hydropower subsidiary, Verbund Austrian Hydro Power AG, is to plan and build the project.
Reisseck 2 is to undergo an environmental impact assessment process, with a declaration submitted by mid-2008. If that is completed according to schedule, the project should be on line by 2014.
Reisseck 2 will be an addition to the six-plant, 138.1-mw Reisseck/Kreuzeck hydroelectric complex in Upper Carinthia. The six plants include 67.5-mw Reisseck annual storage, 23.2-mw Reisseck daily storage, 45-mw Kreuzeck daily storage, 1.6-mw Niklai, 600-kw Muhldorf, and 200-kw Steinfeld.
Verbund said a special feature of Reisseck 2 is that existing storage and equalizing basins with a head of 580 meters will be used. A 5-kilometer tunnel will connect the Reisseck annual storage reservoir and the 730-mw Malta Hauptstufe power plant. Reisseck 2 is to have an underground powerhouse.
The existing Grosser Muhldorfer See Reservoir on the Reisseck Lake plateau will be used as an upper reservoir in pump operation while the lower reservoirs will be the Gosskar and Galgenbichl reservoirs of the Malta power plant group, Malta Hauptstufe, 120-mw Malta Oberstufe, and 41-mw Malta Unterstufe.
