Balancing Pool is responsible for all the costs associated with the remediation and reclamation of ATCO Electric Isolated Generation sites. At December 31, 2011, the reclamation of 100 of 103 Isolated Generation sites was completed. The remaining three sites are large and complex with completion expected by 2012.

We are also responsible for the decommissioning cost of any legacy generating units that are currently under PPAs which retire before 2018 where the total cost to remediate exceeds the decommission funds collected by the owner in prior years. This includes HR Milner, Battle River Units 3 and 4 and Sundance Units 1 and 2. Owners of these assets have 1 year after the expiration of the PPAs to decide if they want to retire these assets and seek any possible funding from the Balancing Pool. Owners who operate these assets past the 1 year limit waive their rights to this funding.
