Enemalta has taken over the Delimara Power Station extension following the successful completion of performance tests, carried out under the supervision of the corporation and external consultants DNV KEMA.
The plant is covered by a 12 month guarantee.
The corporation said in a statement that during the performance tests it was noted that the plant was more efficient than originally specified and was producing an extra 1MW of electricity from the exhaust heat recovery and steam turbine, giving a total of 150MW of electricity, 4MW of which are used within the plant itself.
The tests also confirmed that the abatement system has been producing results which go further than the ones guaranteed in the contract as shown in the following table.

Enemalta’s consultants, DNV KEMA confirmed that the performance test methodology and procedure were in accordance with the contractual requirements and were suitable for the purpose of measuring and calculating the plants performance in terms of the contractual guarantees.
They declared that the tests were satisfactorily carried out and that Enemalta may proceed with the taking over of the plant.
Enemalta will be starting some of the engines to meet this evening’s peak demand.
