Having been on both sides of this my guess is there's a gentleman's agreement between QPM and dyno to free up gas if the electricity price is elevated. Normally boiler operators are nursing some sort of problem so if you get a call from your gas supplier that you might need to cut consumption you come down for opportune maintenance, generally there's some reimbursement afterwards. Of course it might also have been a planned outage that Dyno bought forward.

Speaking of outages looking at the 1yr openNEM chart I would say TPS is due for their turnaround soon. Last one was 28th Aug.
