Gasum Oy is an integrated gas company located in Espoo, Finland. It is the transmission system operator of the natural gas grid of Finland, as also the natural gas importer and seller. Gasum is owned by Fortum (31%), Gazprom (25%), the Finnish Government (24%) and E.ON Ruhrgas (20%). Gasum was established in 1994. The CEO and Chairman of the Board is Antero Jännes.
From 1974 to 1994 Neste Oy was responsible for a gas business in Finland, also the import of natural gas, the transmission services and the wholesale of natural gas. Gasum was established in 1994.
In 2010 Gasum sold a total of 44.6 TWh of natural gas, which covered 10% of Finland's total demand for energy.
Gasum owns 1,190 kilometres (740 mi) of gas transmission network in Finland. The transmission network is Gasum's largest asset and a major part of Gasum personnel, approximately 100 employees work in transmission maintenance duties. The natural gas volume of transmission pipeline is 261,000 cubic metres (9,200,000 cu ft).
As the Finnish natural gas system is connected only with the natural gas system of Russia, Gasum had planned to build a subsea gas pipeline Balticconnector to connect Finland with the Estonian gas system and further with a gas storage in Latvia. The line would have an annual capacity of 2 billion cubic metres (71 billion cubic feet) and cost €100-120 million. As of March 2012, the investment decision is not made.
Gasum plans to build a LNG distribution terminal in Naantali, Finland. The terminal will supply LNG-fueled ships, firstly the Viking Line's new cruise ship to be built in Turku. The terminal will be completed in summer 2013.
In 2011, Gasum started biogas production by using anaerobic digestion. Gasum is cooperating with energy company Helsingin Energia and forest industry company Metsä-Botnia for construction of a biorefinery for biogas production in Joutseno, Finland. The biorefinery would produce biogas from renewable wood raw material for transmission along the Gasum gas network to usage sites such as Helsinki Energy's Vuosaari power plant. This project is a continuation to the letter of intent signed by Gasum and Helsingin Energia in April 2011. If the plan will realised, a biorefinery of this scale could produce an annual total of biogas that is enough to cover the electricity and heat consumption of more than 50,000 homes.
According to the preliminary plan, Metsä-Botnia and its parent company Metsäliitto would be responsible for wood raw material procurement and biorefinery operation. The plan is to mainly produce biogas from forest chips and bark, both of which are available as by-products of pulp mill wood procurement. The production capacity of the planned refinery would be 200 MW.
Gasum and the Kouvola energy company KSS Energia have signed a letter of intent to build a large-scale biogas facility in the Kouvola region. The facility would be fueled by locally produced field biomass. Biogas produced by the plant could be fed into the Gasum's gas transmission system and used as a traffic fuel.[clarification needed] The parties to the letter of intent are committed to studying among other things the technical operating concept of the facility, environmental impacts, potential location and economic feasibility. The Kouvola region is good place to site a this kind of facility producing biogas from energy crops. The region is naturally located with reagds to the natural gas transmission system.
