Responsibilities of TSO & DSOs

TSO: is responsible for system supervision, operation

planning, balance service, grid maintenance, construction and development, and promotion of the electricity market http://www.fingrid.fi/en/

DSOs:The local distribution grid is a natural monopoly, and

requires a permit from the Energy Authority. The grid operator has to connect electricity consumers and producers into the grid and transmit electricity and take care of the voltage quality.

The balancing power marketIs maintained in Finland by Fingrid as a part of the Nordic

balancing power market. The prices of balancing power are determined on the basis of

regulations carried out in the Nordic balancing power market. Both an up-regulating and a down-regulating price is specifiedfor each hour. More here: http://www.fingrid.fi/en/customers/Balance%20services/management/powermarket/Pages/default.aspx
