The load capacity of transmission lines varies depending on the weather conditions. Fingrid’s Dynamic Line Rating project, which began last year, seeks to measure this load capacity and take all of the available thermal transmission capacity in the built network into use. ￫
When French renewable energy expert Neoen wanted to build the Nordics’ largest battery storage unit in Finland, Fingrid was ready and eager to lend a hand. Neoen was looking for a suitable plot and the Finnish TSO had a handy solution available. ￫
Sector integration means bringing the various energy sectors together to enable them to balance out each other’s peaks in consumption and generation. Electricity, heat, gas and transport will be interconnected to provide mutual support to each other. But what does this mean for the power system and the transmission grid? ￫
One of Fingrid’s duties is to connect new, high-capacity power plants to the main grid. The company has made careful preparations for the grid connection of Olkiluoto 3, one of the world’s largest power plant units. The final phase of these preparations includes the implementation of OL3 system protection, which will ensure that the power system functions reliably under all circumstances once the power plant is ready. ￫
Sulphur hexafluoride gas (SF6) has been the primary insulating medium in high-voltage electrical switchgear and controlgear for 40 years. Fingrid prevents the potent greenhouse gas from escaping into the atmosphere by constantly monitoring the equipment where it is used. ￫
Finland has set itself a truly ambitious climate target: Finland will be carbon neutral in 2035, and carbon-negative soon after! A key means of reducing emissions is to eliminate the emissions of industry, heating and transport by electrifying them, writes Jukka Ruusunen, Fingrid's President & CEO.
The ongoing pandemic has caused an unprecedented shock to the continuity of many everyday functions that were previously taken for granted. The pandemic and the consequent state of emergency have put Finland’s overall security to the test, writes Jukka Ruusunen, Fingrid’s President & CEO, who also chairs the Council for Security of Supply and Infrastructure. ￫
Risto Uusitalo, who supervises the work on the Forest Line transmission line worksite, spends his days meeting contractors and conducting site inspections in the field. Many of his colleagues are also familiar with Risto’s dog, Ilona, who sometimes accompanies him on-site. This is the first in a new series of articles about “Professional in the spotlight”. ￫
The new control centre buildings are beginning to resemble family homes in terms of their technical building services and energy efficiency. The buildings are equipped with toilets, small kitchens, heating, ventilation and lighting. ￫
Three different solutions exist for charging electric vehicles: conventional charging, smart charging and bidirectional charging.
“Smart charging is the modern-day solution for households because it takes into consideration the needs of consumers and the environment,” says Ville Väre, Energy Service Manager at Liikennevirta Oy. ￫
This summer, Fingrid will photograph transmission lines from the air. The company intends to photograph approximately 12,000 km of transmission lines – an unprecedented amount. The remainder of the transmission lines (just over 2,000 km) have already been photographed. ￫
In the event of a severe disturbance in electricity distribution, the authorities, municipalities and electricity companies need to work seamlessly together. An extensive, prolonged disturbance in the power network could quickly paralyse society for a long period. ￫
