OL3 EPR’s electricity production starts at the end of February


The OL3 EPR plant unit’s electricity production starts at the end of February, and regular electricity production starts in July 2022. The start of electricity production is postponed due to modification needs observed during the test production phase.

At the test production phase of a nuclear power plant, the plant unit and its safety systems are tested to verify that the plant operations comply with design. During the OL3 plant unit’s test production phase, it was observed that there is a need for modifications in the plant unit’s automation related to control functions, as well as further testing related to the modifications. Corrective measures are under way, but they cause a delay in the test production programme.

The production forecast for the test production phase can be followed in more detail on TVO’s website at www.tvo.fi/ol3forecast. An urgent market message will be released in Nordpool on any significant changes. TVO will also release a stock exchange release in the case that the schedule of the test production phase changes by over three weeks from the previously communicated schedule.

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.
