Polish day-ahead electricity increased for a third day amid lower supply from Sweden and unplanned output reductions at domestic plants.
Next-day power in Poland gained 5.9 percent to 192.81 zloty ($60.85) a megawatt-hour, according to exchange data compiled by Bloomberg.
Electricity flows via the undersea cable from Sweden were set to be cut by 50 percent to 300 megawatts from 9 a.m. to 8 p.m. Stockholm time tomorrow due to maintenance, grid company Svenska Kraftnaet AB said in a filing to the Nord Pool Spot AS exchange. The link predominantly supplies Poland with cheaper Nordic hydropower output. Meanwhile, GDF Suez SA and Enea SA were set to have 485 megawatts of Polish power capacity halted tomorrow, data on company websites showed.
Next-day electricity on the coupled markets of the Czech Republic and Slovakia advanced 4 percent to 54.74 euros ($70.78) a megawatt-hour in a daily auction, according to the countries’ market operators. The day-ahead contract in Hungary settled 3.9 percent higher, also at 54.74 euros a megawatt-hour.
