Metso will supply advanced automation systems and solutions to two new bioenergy power plants currently under construction in Finland, while receiving another replacement order.

Porvoon Energia Oy has ordered a Metso DNA automation system including safety automation for its new biomass-fired power plant located in Tolkkinen, about 50 km northeast of Helsinki. Representing the latest know-how and technology, the plant has a capacity of 12 MW of electricity and 38 MW of thermal heat that will be used for district heating in the town of Porvoo. The boiler will be supplied by MW Power Oy, a company co-owned by Metso and Wärtsilä. The delivery also includes an electrostatic precipitator controlled with Metso DNA. The plant, which will be started up in early 2013, will be fueled by forest residues, bark and sawdust.

Another Metso DNA system including safety automation, field design as well as information and reporting applications will be delivered to a bioenergy plant built by Hämeenkyrön Voima Oy in Hämeenkyrö, located about 220 km northwest of Helsinki. The BFB boiler plant will run on forest residues and other wood-based fuels, with peat as auxiliary fuel. It will produce electricity and process heat for the nearby M-real Kyro paper and board mill, as well as electricity and district heat for Leppäkosken Sähkö Oy, a local electricity company. When started up in the fall of 2012, it will have an electricity capacity of 12 MW and thermal capacity of 55 MW.

Additionally, Metso has received an order from Helsinki Energy, one of the largest energy companies in Finland, for a Metso DNA system to replace an existing automation system in its 118 MW Kellosaari reserve power plant. With the modernized system, the plant ensures that electricity will be available for the Helsinki region in case of sudden nationwide disturbance situations. The delivery also includes safety interlockings, field design, field devices, an information management application and integrated vibration monitoring. The new system will be integrated with the Metso DNA system already used at the Salmisaari power plant, which runs the Kellosaari plant. The renewed automation will be started up in February 2012
