Vantaan Energia awards contract to Hitachi Zosen Inova

On 23 May 2011 the Finnish energy company Vantaan Energia contracted Hitachi Zosen Inova to deliver the combustion / boiler lot to the new combined cycle power plant serving the Helsinki metropolitan area. Two factors – both high operational security and the maximal degree of efficiency – made compelling arguments in favor of the offer by the Zurich based technology supplier.
Massive CO₂ Reduction
Replacing a former coal-powered plant, the new Vaanta plant will reduce coal consumption by some 30%. The plant will be fueled exclusively by municipal solid waste from the Helsinki metropolitan area – the cities Helsinki, Vantaa and Espoo – thus reducing CO₂ emissions from fossil fuels by up to 130.000 t/a. The Waste to Energy (WtE) plant will further contribute to the mitigation of climate change as it will also reduce the emission of Methane from waste which is not longer disposed on landfills.
High Degree of Efficiency
The new facility – slated to begin operation in July 2014 – consists of two WtE units with a capacity of 64 MW each and a nominal throughput of 352.000 t/a municipal solid waste. Steam derived from the municipal solid waste fired boilers will be overheated to 520 °C using exhaust from a gas turbine for combined power and heat production. The maximal output of the combined facility will amount to 78 MW electrical and 107 MW thermal – about 7 MW higher power production compared to a solution with two individual facilities. The heat production will correspond to about half of Vantaa’s annual heat requirement
Technology from the Market Leader
With approval of its EUR 60 million contract, Hitachi Zosen Inova now stands as sole supplier for two key mandates in Finland. By providing the country’s two largest plants – Vaasa und Vantaa – the Swiss firm establishes itself firmly as the number one Waste to Energy (WtE) supplier to Finland. For the Vantaa plant, the Zurich based technology provider also draws on its experience in earlier projects, completed under its former name Von Roll Inova – Helsinki 1961 (no longer operational) and Turku 1975.
