Czech Republic based renewable energy firm CEZ Group has announced details of an extensive refurbishment programme that would see its hydroelectric projects produce an extra 60,000MWh of power over the next 12 years.

Among the projects to benefit from the programme include the Slapy hydroelectric project in central Bohemia, which will see an increase in efficiency of 5% and production increase of 10,000MWH. Also due for refurbishment is the Lipno project in south Bohemia and the Dlouhé Stráne pumped storage power plant in Jeseníky.

Gradual modernisation of impellers and complete overhauls of most units will gradually be carried out on all the power firm’s hydro projects.
