Tasnee announces scheduled maintenance at SEPC

Tasnee affiliate maintenance shutdown to coincide with ethylene cracker expansion works

National Industrialization Co. (Tasnee) announced that Saudi Ethylene and Polyethylene Co. (SEPC), a joint venture between Tasnee and Sahara Olefins Co. that is 60%-owned by Tasnee, will undergo scheduled periodic maintenance starting Jan. 2, for approximately 66 days.

According to a statement to Tadawul, the company said that the shutdown coincides with the extended outage related to the ethylene cracking unit expansion project, in line with technical and operational standards to ensure efficiency, operational safety, and production sustainability.

The shutdown falls within scheduled operational plans aimed at enhancing operational efficiency, improving the plant’s technical performance, and completing the expansion works.

The company pointed out that the financial impact of the shutdown will depend on the actual duration and the average selling prices of products during the shutdown period, and will be reflected in the Q1 2026 financial results. 

Tasnee is taking all necessary measures to mitigate the financial and operational impact of the shutdown period by enhancing the readiness of maintenance and operations teams, the statement noted, adding that it will announce any material developments should they arise.

According to Argaam data, in addition to Tasnee's 60% ownership in SEPC, Sahara International Petrochemical Co. (Sipchem) holds a 32.55% stake in the company.
