The new Länsisalmi substation is important for the electricity supply of Helsinki and Vantaa and for the development of energy supply throughout the area. The opening ceremony for the newest landmark in Vantaa was held on Tuesday 27 March 2018.
The entire electricity system is undergoing an unprecedented change. Fingrid’s aim is to have effectively functioning electricity markets in the Baltic Sea region that ensure reliability of supply in all conditions. However, the “clean electricity system of the future” will require strong transmission connections in order to operate optimally.
Fingrid reacted quickly to Kemira’s plant expansion in Joutseno by renewing the main grid in Southern Karelia and building a new substation in the Joutseno area. This ensures that the growing need for power and electricity consumption can also be met in the future.
The end of August was an historic moment at Alajärvi substation, as the last air blast circuit breakers in the main grid were removed from use as part of the substation renewal project. Project Manager Sami Mäki and Expert Heikki Porkka, who planned the transmission outages, have been involved in the different stages of this substation.
The launch of a cross-border, intraday market model is an important step forward, but the European electricity market needs more changes, believes Tomasz Sikorski, Vice President and COO of PSE, which is the Polish Transmission System Operator.
Fingrid continued to make large investments and develop its operations in 2017. The company is in good financial condition and the result has developed as expected and according to regulation. Turnover was 672 million euros and more than 111 million euros were spent on investments.
Following closure of the Elektra electricity museum, its contents will be transferred to the Museum of Technology collections. One particular aim was to keep the main grid collection, which describes the construction and maintenance of the main grid, as a single entity. Part of the collection will be displayed in the new Land of Technology exhibition opening in October.
Modernisation of the Rautarouva (Iron Lady) line, which is the oldest section of Finland’s main grid, is nearing completion. Work to renew the 82-kilometre Koria-Ylilikkälä power line is currently in progress. The 110-kilovolt power line is being dismantled and replaced with a new 400-kilovolt line.
Fingrid and Teollisuuden Voima (TVO) have begun preparations to connect Olkiluoto 3 to the main grid. The connection will require special arrangements because, once completed, Olkiluoto 3 will be considerably larger than earlier electricity production units.
In accordance with its mission, Fingrid has been developing the main grid throughout its 20-year history. The grid development work consists of planning the main power transmission grid and the regional grid, which Fingrid does in cooperation with its customers. This collaboration has recently become even closer.
