The company performing imbalance settlement for balance responsible parties across the Nordics, jointly owned by the four transmission system operators.
Definition
eSett Oy was founded in 2013 by Svenska kraftnätSweden's system operator for the transmission network - equivalent to Statnett's role in Norway., FingridFinland's transmission system operator - owns and operates the Finnish high-voltage grid and runs the Finnish Datahub. and StatnettNorway's system operator for the transmission grid - owns and operates the high-voltage network and operates Elhub., with the aim of establishing one joint imbalance settlementTurning metering data into money. Consumption and production per metering point become what each party owes or is owed. for Sweden, Finland and Norway. In 2017 the company took over operational responsibility for settling and invoicing market participants in those three countries.
Denmark followed later. EnerginetDenmark's system operator for electricity and gas - operates the transmission network and runs DataHub Denmark for market data exchange. signed an agreement to become a shareholder in 2019, and the Danish market was integrated into Nordic Balance SettlementFinancial settlement between BRPs and the system operator for energy imbalances in a given period. from 1 February 2021. Ownership is now split equally between the four transmission system operators, 25 per cent each.
The job is the same for all four: calculate each balance responsible party's imbalance, meaning the difference between what was scheduled and what was actually delivered or consumed, and invoice it. The background is that this used to be done separately in each country, with its own deadlines, formats and processes.
⚠️ **Imbalance settlement really is Nordic. The hubs are not.** That is a distinction worth holding on to: every balance responsible party in the Nordics follows the same settlement rules and has eSett as a common operator, while metering data and market processes run through four different national arrangements, and Sweden has none yet.
The format going into eSett has been a practical question for parties without a customer information system that supports it. They have solved it by mapping to older message formats along the way, the same translator role the EDI platforms have played towards Elhub.
