IN Brief:
- Salko UK has secured a four-year framework covering Enfield, Grain, and Taylors Lane within Uniper’s UK power station portfolio.
- The Enfield scope includes a high-priority tube bundle replacement on the once-through cooler, alongside ongoing gas turbine exhaust maintenance.
- The work sits alongside wider GT26 modernisation activity across Uniper’s fleet, including GE Vernova’s upgrade programme at Grain due to begin in 2026.
Salko UK has been awarded a four-year contract covering supply and on-site works for the Once-Through Cooler and gas turbine exhaust systems at Uniper’s Enfield Power Station in Brimsdown, London, while also continuing maintenance activity at Grain and Taylors Lane power stations under the same framework. The agreement covers ten planned projects over the term and extends Salko’s role in maintaining critical plant systems across Uniper’s flexible UK generation assets.
At Enfield, the main scope centres on a high-priority tube bundle replacement for the high-pressure cooling system within the station’s once-through cooler. The work includes removal of existing components, fabrication, installation, inspection, testing, and commissioning, with the objective of improving thermal performance, restoring mechanical integrity, and reducing the risk of unplanned outages. Salko will also continue maintenance on the gas turbine exhaust system, where the focus is on extending asset life and supporting plant reliability during starts and operation.
The package brings together mechanical, electrical, and tooling work under a dedicated specialist team. In practical terms, the Uniper award links planned outage work with longer-cycle maintenance support across three stations rather than treating individual repairs as stand-alone interventions. That reflects the way ageing gas assets are increasingly being managed, with reliability work, refurbishment, and performance upgrades advancing in parallel.
The framework also lands against a wider programme of GT26 asset modernisation within Uniper’s fleet. At Grain, GE Vernova is due to upgrade three GT26 gas turbines from 2026, following earlier work at Enfield that improved output, efficiency, fuel consumption, and maintenance intervals. Together, those projects point to a broader strategy of extending the operating life and flexibility of existing gas-fired generation while lowering carbon intensity per megawatt generated.
For Uniper, the latest contract keeps balance-of-plant reliability work moving alongside turbine upgrade activity across sites that remain important to flexible power supply. More on Salko UK’s services is available on its website.
