The £223m facility, which has been developed EPC contractor CNIM/Lagan, is undergoing reliability testing in preparation for performance testing scheduled in April.
The project, which created 600 jobs during the peak of construction phase, is currently going through final testing and will validate its R1 status.
R1 is required to ensure that the facility is operating at, or in excess of the energy efficiency threshold required to be officially classified as an Energy Recovery Facility. The facility is capable of processing 350,000 tons of residual waste, or post-recycling waste, per year in order to generate electricity.
Viridor Trident Park ERF general manager Dai Stephens said: "Trident Park is exporting 30MW of base load electricity to the grid, enough energy to power around 50,000 households."
Viridor capital projects and engineering director Alan Cumming said: "It’s great to see Trident Park ERF move into its operations phase.
"The project has provided employment, training and wider economic and community benefits and will now provide an essential service and jobs for those working on the Plant and supporting it during its 25 year life.
