Neste to invest over EUR 400 million in Porvoo refinery turnaround
- Neste will shut its Porvoo refinery for an approximately nine-week maintenance turnaround between August and October 2026.
- Total estimated cost is over EUR 400 million and about 7,500 people will work on the turnaround, including around 1,000 Neste employees.
- More than a hundred contractor companies will supply specialists; over 80% of the selected contractors are Finnish and experts will arrive from Germany, Poland, Spain, Sweden, the Netherlands and the UK.
- Fuel deliveries, the Kilpilahti port and the Porvoo distribution terminal will operate normally; increased local traffic, short-term flaring and potential noise disruptions are expected.
Scope and schedule
Neste will carry out an approximately nine-week maintenance turnaround at its Porvoo refinery between August and October 2026. The turnaround will focus on tasks that require a refinery shutdown, including statutory inspections, routine maintenance and asset improvement initiatives; such maintenance is typically held at intervals of 2.5 to 3 years.
Cost and workforce
The total estimated cost of the project is over EUR 400 million. Around 7,500 people will participate in the work — roughly 1,000 are Neste employees and the remainder are experts from more than a hundred contractor companies, says Jim Holmbäck, Director, Turnarounds.
Supply continuity
Fuel deliveries to customers will continue throughout the maintenance turnaround. Security of supply will be maintained by producing and storing goods in advance, and the Kilpilahti port and the Porvoo distribution terminal will operate normally during the work.
Local impacts and logistics
The turnaround will significantly increase traffic in the Kilpilahti area and special traffic arrangements will be published on the local Kilpilahti website prior to the work. Short-term flaring and potential noise disruption may occur during both shutdown and startup; Neste says it aims to minimise disturbances to local residents and other traffic.
