Poland's grid operator, PSE, temporarily disconnected its solar and wind facilities due to an oversupply of renewable energy, putting the country's electrical grid at risk.

The oversupply of electricity, which exceeded 3 gigawatts, necessitated the reduction of renewable energy sources connected to the medium and low-voltage grid. PSE's actions aimed to ensure the safe operation of the national power system and to prevent significant disruptions in the supply of electricity to customers. Poland officials had previously acknowledged that an upgrade to its power grid is necessary if the country is to cope with the transmission of energy from renewable and nuclear sources.

Poland generates about 70% of its power from coal and has been working on a new energy strategy since the start of the war in Ukraine to reduce its dependence on fossil fuels. The country's new strategy envisages nearly three-fourths of energy coming from zero-emission sources, including renewables and nuclear power. PSE's CEO, Tomasz Sikorski, said that Poland needed to invest more than $116 billion in transmission grids by 2040 to achieve its energy goals. Sunday marked the second time since September that the grid operator has temporarily disconnected solar sources from the grid due to oversupply.
