It is a Monday morning, and a call comes in from the main grid control centre. Over the weekend, the Swedish transmission system operator Svenska kraftnät (Svk) began limiting the transmission of electricity from Finland to Central Sweden. I recalled a moment last summer when Svk was forced to limit the transmission of electricity from Norway, leading to confusion in the electricity markets – surely history will not repeat itself on the border between Finland and Sweden...?
Fingrid has developed a quick and cost-efficient solution for increasing the electricity transmission capacity between Northern and Southern Finland. The innovation, which is based on a new application of an existing technology, is a quick, cost-efficient and environmentally friendly way of adding up to 500 megawatts of additional transmission capacity to the grid.
On the electricity market, the constraining factor for the transmission grid is the amount of electricity that can be transmitted at any one time. The Flow based calculation method enables transmission capacity usage to be optimised according to demand for electrical energy.
