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.
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.
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.
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.
Fingrid has started the development of mobile and browser applications for main grid information contained in the ELVIS system.
Fingrid has named the 400-kilovolt transmission line connections between north and south in the spirit of Finland’s 100th anniversary:
Fingrid has received several inquiries about locating solar power plants in transmission line areas. However, it is not possible from the main grid’s perspective. Locating a wind power plant near a main grid transmission line is also problematic. Guidelines concerning wind and solar power plants are included in the updated planning guidelines meant for land-use planners from municipalities.
