The start of OL3 EPR’s regular electricity production postponed to September


According to information received from the plant supplier, the regular electricity production of the OL3 EPR plant unit starts in September 2022, instead of the previously estimated start at the end of July.

Inspection and repair needs concerning the cooling system of OL3’s generator will last approximately three weeks. The plant unit’s test production programme and electricity production will continue after the repair work. Furthermore, additional time has been reserved in the schedule for the plant unit’s upcoming testing and their analyses based on previous experiences from the test production phase.

The inspection and possible repair needs of the generator’s cooling system are not related to the information given earlier this week about the boron pumps turning on unexpectedly and related automation modifications.

The production forecast for the test production phase can be followed online at An urgent market message will be released in Nordpool on any significant changes.

The OL3 EPR plant supplier consortium is constructing the plant unit under a fixed-price turnkey contract. The supplier consortium companies, AREVA GmbH, AREVA NP SAS, and Siemens AG, have joint and several liability for the contractual obligations until the end of the guarantee period of the plant unit.
