New 40MW Kaplan for Iffesheim plant on Rhine

20 March 2007

The company's subsidiary in charge of the plant - EnBW Energie Baden-Wurttemburg - plans to install a 40MW Kaplan bulb turbine, generator and auxiliary electrical equipment, IWP&DC was told.

Deadline for prequalification by expressing interest to tender is 11 April, and there is a second deadline - 17 April - on protection devices.

Tender deadline is anticipated to be in August for contract award possibly before year-end.

Iffesheim is 29 years old and has a total power capacity of 110MW from its four Kaplan units. Existing average annual electricity output is 740M kW per hour.

The expansion programme will enlarge the powerhouse structure as well as install a new penstock, tailrace and the turbine-generator set, thereby making it the largest hydro plant on the Rhine, the company said.

EnBW told IWP&DC that the extra capacity for the plant, sited near Baden Baden, should be commissioned by mid-2010. The expansion works at the plant are scheduled to commence in 2008, it added.

When approval of the expansion programme was first given, in late 2005, the additional capacity from a new unit was estimated at about 38MW with a Kaplan wheel diameter of about 7.40m.

The Plant is operated by the power company Rheinkraftwerk Iffezheim, which is jointly owned by EnBW and French producer Electricite de France (EDF). The expansion project is being led by EnBW.
