Yes, it's a little buried but the article says > The energy turnover results from the coupled heating power multiplied by the duration of the discharge The numbers: > The energy turnover of 1.3 gigajoule was achieved with an average heating power of 2.7 megawatts, whereby the discharge lasted 480 seconds Also: > Within a few years, the plan is to increase the energy turnover at Wendelstein 7-X to 18 gigajoules, with the plasma then being kept stable for half an hour i.e. 10 megawatts for 30 minutes
