Fingrid’s September customer event in Vantaa addressed serious disturbances and a power shortage in the electricity system.
Fingrid has consistently been successful in the International Transmission Operations and Maintenance Study (ITOMS). The company was at the top of the 2015 study for the 11th consecutive time. ITOMS is held every two years.
What if the electricity was cut off for a couple of weeks because of exceptional weather conditions? What would happen to the flow of information if normal communication devices didn’t work? Where would citizens get heat and water and how would we secure fuel distribution? These threats were the starting points for the large Jäätyvä (dealing with a widespread power outage caused by freezing weather) exercise held in Kuopio in October.
Fingrid is asking land owners and residents living near transmission lines to provide feedback as the basis for developing communications, also using new tools. E-mail, Facebook and SMS messages have been tested for land owner communications in the Vanaja–Tikinmaa construction project. An informative tower erection display attracted a large audience in Hämeenlinna.
Many disturbance situations in overhead lines can be rapidly cleared using relay protection and automatic reclosing.
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.
Fingrid has organised its service offering to give a clearer picture of its role.
The latest addition to Fingrid’s HR unit, a software robot called Tero Tiima, has been introduced to routine payroll administration tasks. This will provide the staff with more time for personal encounters. It also speeds up the payroll process and reduces the number of human errors.
The Smart grid working group appointed by the Ministry of Economic Affairs and Employment has published its interim report. The main message is that, in the future, consumers will have more opportunities to participate in the electricity market and be able to influence their electricity bill to a greater extent. A smart electricity system will provide actors with more possibilities, and is a cost-effective way to respond to the challenges of the energy transformation.
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.
