The turbine is part of a production unit that also includes a heat recovery boiler and a 50 MW steam turbine, HEP said in the November issue of its in-house newsletter.
The new production unit is expected to be commissioned for commercial operation in the second quarter of 2014.
In 2007, HEP subsidiary HEP Proizvodnja, which operates TE Sisak, hired Russia's Technopromexport to supply the technology for the new unit. The deal was signed as part of an agreement between the Russian and Croatian governments on the repayment of the debt of the former Soviet Union to ex-Yugoslavia.
TE Sisak currently operates two units of 210 MW each.
HEP group (www.hep.hr) owns and operates over 4,000 MW of installed generation capacity and 974 MW of heat production capacity, including 25 hydroelectric plants and eight thermal power plants fired by oil, natural gas and coal.
