Lethabo Power Station: Turbine Safety Valve Refurbishment

Location: Lethabo Power Station, Eskom

Date: May/June 2026

Team: JAG Site Support

 The Challenge:

During a planned shutdown at Lethabo Power Station, the turbine safety valves required full refurbishment and pressure testing within a tight outage window. These valves protect critical turbine equipment from sudden overpressure events, so precision and timing were equally non-negotiable.

 What JAG Delivered:

The team stripped down, refurbished, and pressure tested the turbine safety valves to exacting standards, working in lockstep with Eskom’s shutdown coordination teams and adapting quickly as schedules shifted.

 Results:

• On-time completion within the shutdown window, with no delays to the wider programme
• Zero quality issues: every valve met technical and performance standards for safe return to service
• Zero safety incidents throughout the project
