The Group Chief Executive Officer, Nigerian National Petroleum Corporation Ltd (NNPCL), Mr Mele Kyari, on Thursday said the Port Harcourt refinery would begin production by end of March.

Kyari said this after a meeting with the Senate Ad-hoc Committee, investigating the various Turn Around Maintenance (TAM) projects of Nigerian refineries.

On Warri refinery, Kyari said mechanical works had been completed, adding that the facility was undergoing the regulatory compliance processes.

He, however, said Kaduna would not be ready until December.
