Cutia Wind Farm Complex

The start-up of the Cutia Wind Farm Complex, initially scheduled for July 2018, was revised to August 2018. In accordance with the Reserve Energy Agreement (CER), estimated revenue for the period between October 1, 2017 and the start-up of each generating unit of the wind farms will be retained and used to offset reimbursements due arising from any annual and/or four-year generation that is below the contracted amount. Any positive remaining amount will be recorded as credit.

It is worth mentioning that, pursuant to the CER, failure to deliver energy does not subject the seller to financial exposure in the Short-term Market.
