Power outage at Polish plant is felt across European grid
Print Edition
Energy experts worked on Tuesday to restore full operations at Poland鈥檚 biggest power plant after a network failure switched off 10 of the brown coal-fueled Belchatow plant鈥檚 11 units, a disruption felt across Europe鈥檚 power network.
Poland needed emergency energy imports from Germany, Sweden, the Czech Republic and Slovakia to fill in for the suddenly missing power supply. It was a second major outage since 2015 at Belchatow, which provides up to 20 percent of the energy in Poland.
The outage at the lignite-fired station was felt across Europe鈥檚 continent-wide network of power grids.
Operators recorded a sudden drop in mains frequency from the standard 50 Hz to about 49.85 Hz. Other power supply companies had to scramble to compensate for what was a major deviation to prevent consumers from feeling the change.
Officials said the outage was the units鈥 automatic reply to a failure at a nearby power switchboard where 10 of Belchatow鈥檚 units are connected. The 11th unit, the largest, is connected to a different switchboard and was not affected.
Poland鈥檚 chief energy distributor, state mining and energy giant PGE, said on Tuesday that eight of the units had been restored but that restarting them after a total cut was a big challenge.
PGE spokesperson Beata Jarosz-Dziekanowska said the nationwide energy system was working properly and no power shortages were expected.
鈥淎s the system鈥檚 operator, we have the required reserves, and we can always use imports,鈥 Jarosz-Dziekanowska said.
The outage underscored the need for a diversification of Poland鈥檚 energy sources. The country of 38 million gets 65 percent of its power from black coal and lignite, mostly from its own deposits.
Environmental groups say Poland is Europe鈥檚 laggard in phasing out polluting fossil fuels and introducing clean energy.
