WARSAW: Electricity imports into Poland from Sweden and Lithuania were cut to zero in most hours on Wednesday following technical issues that affected the country’s power exchange TGE. Hourly prices for the country’s second closing time peaked at €215.00/MWh. TGE’s technical problems prevented it from sending day-ahead bids to the power exchange Nordpool. As a result capacity was cut to zero in most hours on the SwePol and LitPol cables which have a capacity of 1.1GW. The missing capacity made the system tighter because it represents just above 6% of the country’s average demand of 18GWh.
Data from TGE indicated that on Wednesday, electricity flows on the Lithuanian-Polish interconnector will remain at zero. But some flows were nominated on the border with Sweden with 54MW in hour 7 and 300MW in hours 22, 23 and 24. The incident also delayed the calculation of the second fixing price for Wednesday’s delivery, with the Day-ahead Baseload outturn settling at Polish zloty (Zl) 240.78/MWh (€54.81/MWh). Neighbouring Germany settled at €30.58/MWh. The highest price of Zl 944.70/MWh out-turned in hour 12.
A trader said the overall second closing price was pressured by the price of the first fixing. This is because news of the event only emerged after the first fixing closed. The Polish exchange has two closing times, referred to as fixings, for day-ahead trading. The first is published at 10:30 CET and the second at 11:30.
