Czech equipment manufacturer CKD Blansko Holding delivered a replacement runner May 23 to the 450-MW Dalesice pumped-storage project on the Jilhava River in the Czech Republic.
The upgraded nine-bladed Francis runner is 6,000 millimeters in diameter and weighs 80 tons, CKD Blansko said. It is expected to perform with higher efficiency and allow Czech utility CEZ to generate �considerably more� power, the supplier said.
Delivery of the runner is part of a 4.2 million euro (US$5.7 million) contract for upgrading and overhaul of Unit 2 of the four-unit pumped-storage project.
CKD Blansko Holding is carrying out a similar runner upgrade project for two units of the 800-MW Zarnowiec pumped-storage project in Poland. The company received a US$7.5 million contact for that work from project operator Elektrownie Szczytowo-Pompowe S.A. in 2006. (HNN 11/29/06)
