Electricity transmission system operator LITGRID AB received 32,4 million euros congestion income in 2020 – announced in Congestion income report for 2020 prepared by the National Energy Regulatory Council (NERC) (download).
Congestion income originates from the prices difference between bidding zones. In 2020, the largest congestion income LITGRID AB received due to the price difference between Lithuania and Sweden bidding zones (more than 20,9 million euros). The resulting amount of price difference should be paid to the transmission operator by the exchange operator.
In accordance with the requirements of the legal acts of the European Union, the congestion income received by the transmission system operator should be directed primarily to be used to invest in transmission system, i.e. construction of interconnectors, strengthening internal network and other. This is the reason to ensure the integration and development of the European Union electricity market.

In accordance with significant and large-scale investments in the National Energy Strategy, balance of unused congestion income – 62,5 million euros – will be used to finance the synchronization project with continental Europe in the future.
