Alstom has received a contract to upgrade an existing steam turbine at Mälarenergi power plant located in Vasteras, Sweden.

Under the contract, Alstom will upgrade two of the three rotors of the steam turbine in order to enhance their technical service life and adapt the turbine for the flow of steam from Mälarenergi’s biomass boiler, which runs on 100% biofuel.

Mälarenergi vice managing director and business area manager at Nicklas Gunnar said: "Alstom has developed a unique and attractive technical solution for Mälarenergi that will enable us to continue using this steam turbine for several more years, now only being fed steam from our biomass boiler, which means that the modernised steam turbine will produce fossil-free electricity and district heating.

Work under the contract will begin immediately to ensure that the steam turbine is ready for operation ahead of the heating season in autumn 2015.

Alstom Power Sweden managing director Mats Andersson said: "This order is very important for Alstom and confirms the company’s expertise in producing attractive, eco-friendly solutions for power station modernisations. We are looking forward to a good cooperation with Mälarenergi during project implementation."

Alstom Power in Norrköping will be responsible for the project delivery.
