Czech utility CEZ has awarded a US$3.4 million contract to CKD Blansko Engineering Inc. to provide mechanical overhauls of turbine-generator TG1 at the 120-MW Lipno 1 hydropower project.
CEZ most recently sought bids for the work in December for an overhaul of TG1 including disassembly and reassembly, a new runner, guide vanes, distributor, coil, lubrication units, bearings, hydraulic regulator, servo-diffuser ring, shaft, testing and documentation. The work is to be performed through next August.
CEZ awarded a contract in 2012 to Servis-Energo s.r.o. to repair or replace generator stator windings and repair generator components at Lipno 1 and 1.5-MW Lipno 2. In 2011, the utility sought replacement generator and turbine components for its hydroelectric projects in the Vlatava River cascade. In other recent Czech hydro work, South Bohemia’s water utility awarded a contract to CKD Blansko Engineering to supply a turbine-generator for the intake of the Plav water treatment plant.
