Available nuclear capacity
What this shows
This is the available nuclear capacity in a bidding zone. It is built from two ENTSO-E datasets: the zone's installed nuclear capacity (Installed Capacity per Production Type) minus the published unit outages (Unavailability of Generation and Production Units).
Planned unavailability is published up to three years ahead with an estimated start and end and the available capacity during the event, so the forecast horizon reflects scheduled refuelling and derates with real return dates rather than a value carried flat from the last reading. Forced (unplanned) outages explain dips in the recent history.
Read it as an indicative outlook, not a guarantee: estimated end dates and available capacities are revised as the date approaches, and the threshold for disclosure is a change of 100 MW or more, so very small movements are not captured.
