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).

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.
