The Nigerian National Petroleum Company Limited (NNPC Ltd) has announced that the Port Harcourt Refining Company (PHRC) will undergo a planned maintenance shutdown.

Olufemi Soneye, the chief corporate communications officer of the company, in a statement on Saturday said the scheduled maintenance and sustainability assessment will commence on 24 May.

“The Nigerian National Petroleum Company Limited (NNPC Ltd) wishes to inform the general public that the Port Harcourt Refining Company (PHRC) will undergo a planned maintenance shutdown. This scheduled maintenance and sustainability assessment will commence on May 24, 2025.

“We are working closely with all relevant stakeholders, including the Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA), to ensure the maintenance and assessment activities are carried out efficiently and transparently,” Mr Soneye said.

He said NNPC Ltd remains steadfast in its commitment to delivering sustainable energy for Nigeria.

“Further updates will be provided regularly through our official channels, including our website, media platforms, and public statements,” he said.

The Port Harcourt Refineries comprise two units, with the old plant having a refining capacity of 60,000 barrels per day (bpd) and the new plant 150,000 bpd, both summing up to 210,000 bpd.

The refinery has not operated maximally for over two decades. It was shut down in March 2019 for the first phase of repair works after the government secured the service of Italy’s Maire Tecnimont to handle the review of the refinery complex, with oil major Eni appointed technical adviser.

In 2021, NNPC Ltd said repairs had started at the refinery after the Federal Executive Council (FEC) approved $1.5 billion for the project.

On 21 December 2023, the Nigerian government announced the mechanical completion and the flare start-off of the refinery.
