Alberta Hydro PPA's expiryI did some further digging and it seems that the Alberta Hydro PPA's expired on Dec 31, 2020. So Q1 2021 should reflect the increase in revenue from the hydro assets.
This from the footnoted in the annual report and a statement by the Balancing Pool
"Since 2018, the Balancing Pool has been managing 2,284 MW of generation capacity in Alberta's electricity market for generation assets that were governed by the terms of the Genesee, Sheerness, Keephills and Hydro PPAs (the "Remaining PPAs").
The Remaining PPAs expire at midnight on December 31, 2020. Upon expiration, the Balancing Pool will no longer have an active position in the wholesale electricity market and the role of market participant will revert back to the generation facility owner. The generation facility owner will have sole authority to make decisions regarding if and how the underlying generation assets will be operated in the market.
Following expiry of the Remaining PPAs, the Balancing Pool will continue to manage residual PPA related matters and other ongoing nonPPA responsibilities"
