Other than during testing and commissioning, the Procuring Authority did not closely monitor performance during the construction phase. The PPP contract set key milestones that the Project Company was required to achieve, which were:

•  Obtaining environmental licences;

•  Start of construction;

•  River flow detour;

•  Start of electromechanical assembly

•  Start of commissioning

•  Start of commercial operation

Failure to achieve the milestones can result in payments due to the Procuring Authority, the liability for which is guaranteed by a performance bond provided by the Project Company. If there are any issues or failure in meeting the milestones, the Procuring Authority could undertake site visits to investigate the causes.

The Procuring Authority's role in the monitoring of the project reduces after the testing and commissioning phase is completed. When the power plant entered into service, the Grid Operator took over the performance monitoring of the Project Company from the Procuring Authority. The operations are monitored in real time and the associated performance monitoring reports are made available on the public domain. The Procuring Authority continues to be responsible during the operations phase for the monitoring of the Project Company's compliance with the contract terms and any breaches could lead to liabilities for the Project Company for agreed compensation payable to the Procuring Authority.
