On the day of 27 March 2014 Ecoenergia signed a contract with Energomontaż Zachód Sp. z o.o. Wrocław covering cooperation during execution of the contract with PGNiG Termika for modernization of the boiler house containing four PTWM-100 boilers operated by WOLA district heating plant. The contract is aimed at conversion of mazout fired boilers (K2, K3 and K4) into Ekoterm light oil units. Ecoenergia will be responsible for preparation of technical documentation and supply of combustion equipment that will enable the boilers to meet the IED Directive SO2, NOx and dust emission limits that will become obligatory in the year 2016. The boilers will be modernized successively: K3 unit in 2014 and K2/K4 in the year 2015.
