The addition of the world’s largest sand battery to the Vääksy district heating network and Enico’s domestic battery solutions show that the reserve market now includes more than just large industrial loads. It is about smart trading and technological leadership.
Solar power is a cheap, renewable and emission-free energy source, and the construction of a solar power plant is fast. Producers appreciate Fingrid’s willingness
to work with them.
Finland’s first grid energy storage facility with grid-forming capabilities was opened in Valkeakoski last autumn. Other new grid energy storage systems are expected to have the same capabilities.
A fair and effective electricity market is in
everyone’s best interests, and up-to-date
information is required to ensure this. Data from a variety of sources plays a key role in optimising electricity production, consumption and transmission.
Balancing market in the Nordic electricity system was overhauled in March. The balancing of production and consumption is now separately done for each bidding zone, whereas balancing was previously done for the Nordic synchronous area as a whole. There is an increased need for balancing in the Finnish electricity system, and price spikes have become more common.
Traditional power plants have been increasingly replaced by wind and solar power, whose output varies according to weather conditions. This poses predictability challenges and new requirements to ensure the stability of the electricity grid.
Power exchanges are constantly innovating and developing to respond to the transformation of the electricity market.
Turnkey service providers can help their clients enter the reserve market. Optimisation solutions identify the best possible return per megawatt.
Lidl Finland and Lumme Energia sell their capacity for flexible electricity consumption to Fingrid, helping to keep the power system in balance. Flexibility
can be found in surprising places and can be handsomely rewarded.
An electricity network can transmit a limited volume of electricity within the constraints of system security. Fingrid manages electricity transmission to ensure that it remains within the limits of the transmission capacity at all times.
