Riyadh, Saudi Arabia - NOMAC Maintenance Energy Services (NMES), the field service affiliate of Saudi-based ACWA Power, and EthosEnergy, a global leader in gas turbine components, refurbishment and engineering, have signed a strategic collaboration agreement to introduce a transformative, on-site, Rotor Lifetime Assessment and Extension (RLE) solution for GE Frame 7E, EA, and FA gas turbines within the Kingdom of Saudi Arabia.
EthosEnergy is proud to partner with ACWA Power’s affiliate, NMES, to launch a first-of-its-kind on-site Rotor Lifetime Assessment and Extension (RLE) solution for GE Frame 7E, EA, and FA turbines.
This collaboration marks a significant step forward in providing end-to-end on-site rotating equipment services with unmatched speed and efficiency across the region and beyond.

The company offers proven experience in designing, manufacturing, and installing Frame 7 rotors and subcomponents.
NMES, ACWA Power’s internal LTSA and field service provider, is a global partner to independent power producers (IPPs) and government utilities. Specializing in delivering advanced workshop-level capabilities directly on-site, NMES offers services including rotor unstacking and restacking, laser welding and precision machining, on-site balancing and inspection, as well as critical NDT and on-site component replacement, which eliminates the risks and delays of overseas transport, customs clearance, shipping, and related costs.
Through this collaboration, NMES and EthosEnergy will jointly offer a fully integrated RLE solution that includes:
- Supply of seed rotors (new or certified refurbished)
- Full on-site rotor lifetime assessment and extension
- On-site Critical NDT and machining services
- Parts replacement and recertification
- Open/close/inspect of the unit as part of a HGP or MI
We’re thrilled to partner with EthosEnergy, enabling us to deliver not only the expertise and machinery to perform these works on-site, but also the required parts, providing a comprehensive solution in the shortest timeframe, and at the most competitive price
This partnership is a testament to what’s possible when two industry leaders come together with a shared commitment to innovation and performance. By combining our technical depth in rotor engineering and manufacturing with NMES’s world-class field execution, we are enabling operators to significantly reduce outage duration, cost and risk. It’s a positive step for the region’s energy infrastructure, and we are proud to be a part of it.
