Looking to the future

The power system vision will be completed in the autumn. The network vision’s scenarios for the future foresee dramatic changes in the current power system and clarifies the energy sector’s overall status in the energy revolution.

Batteries as part of the energy system

The energy revolution requires the main grid and the entire energy system to be prepared for the fluctuations in generation output caused by renewable forms of energy. Batteries offer the possibility of the quick and accurate balancing of generation and consumption.


The importance of electrical systems to society

We live in two worlds. One is the physical world, and the other is a digital world based on technology people have created. We have adapted and evolved to live in the former throughout the history of humankind, but the digital world is still relatively new to us, writes Jarno Limnéll.

Henna Virkkunen: A market-based energy system is the key to sustainable growth

Henna Virkkunen, a member of the European Parliament, believes that a diverse, market-based energy system is the most effective operating model for Europe’s sustainable growth economy. Investment subsidies for new energy sources are justified in the early phases of production, but over the long term, societally-funded energy needs to establish a competitive position in the market through demand.

20 years of intraday trading

The 1st of March was an important milestone in the European electricity market. On that day 20 years ago, continuous intraday trading between Finland and Sweden started with the ELBAS product. At the same time, Fingrid removed the cross-border transmission tariffs from its Nordic connections.


New measurement systems – better reliability

A renewed system to measure power quality and new travelling wave fault location will improve power quality monitoring and disturbance clearing in Fingrid’s main grid. The investments in new measurement equipment allow more effective anticipation, location and investigation of faults that pose a threat to the main grid. This will also enhance electrical safety in the main grid.

What challenges does the power system face during the summer?

For the power system, summer doesn’t just mean warm and gentle breezes. We asked Operational Development Manager Jonne Jäppinen to tell us about the challenges that summer presents in terms of the electricity grid and electricity production.
