MRO stands for maintenance, repair, and overhaul. In power generation, MRO services cover the scheduled inspections, component repairs, refurbishment, and full overhauls required to keep gas turbines, generators, and balance-of-plant equipment operating safely and reliably across their service life.
Protect turbine availability, control maintenance costs, and extend asset life.
Maintenance, Repair, and Overhaul Services for Power Generation Equipment
Prismecs delivers MRO services for gas turbines, generators, and balance-of-plant equipment. Our engineers coordinate inspections, repairs, refurbishment, and overhauls to reduce downtime, restore performance, and provide visibility into asset condition and lifecycle costs.
Reliable MRO Services That Keep Power
Generation Assets Performing
Unplanned turbine trips, delayed inspections, and poorly coordinated overhauls can reduce power plant availability, affect grid commitments, and accelerate equipment degradation. Without a structured MRO strategy, deferred maintenance can also increase forced outages and lifecycle costs.
Prismecs coordinates maintenance, repair, and overhaul activities through OEMs, authorized workshops, and qualified specialist partners.
From combustion and major inspections to hot section exchanges and rotor life extension, Prismecs coordinates the work, schedule, quality, and technical documentation, helping operators keep equipment operational while reducing internal coordination.
What We Cover Across MRO Services
Prismecs manages the full MRO lifecycle, coordinating inspections, repairs, overhauls, and return-to-service support for critical power generation equipment.
We review operating history, previous outage findings, operating hours, start cycles, and trip data to define the appropriate inspection scope. Borescope inspections, NDT, dimensional checks, and calibration are used to identify equipment condition issues before repair decisions are made.
Prismecs manages turbine repair and overhaul programs for aeroderivative and heavy-frame gas turbines, including LM2500, LM6000, TM2500, GE Frame 5, 6, 7, and 9 units. We also support repair and overhaul programs for Solar Titan, Solar Taurus, and Solar Centaur gas turbines. Across these turbine types, the scope is based on inspection findings and may include field repairs, workshop refurbishment, component exchange, or complete engine overhaul.
To minimize downtime, Prismecs coordinates hot section and rotatable exchange programs. Pre-overhauled modules or exchange engines are prepared in advance and installed on site, allowing the removed components to be repaired separately while the power plant returns to service in days rather than weeks.
Our MRO services extend beyond the gas turbine to include generator rewind and rotor repair. We coordinate stator rewinds, rotor rewinds, insulation replacement, retaining ring inspections, and rotor balancing through qualified repair facilities to restore generator reliability and extend service life.
Prismecs assesses critical spares, verifies physical inventory, and manages repairable and rotating spares. We identify long-lead items, evaluate repair-versus-replacement needs, and track shelf life, preservation, and parts usage to reduce emergency sourcing and keep overhauls on schedule.
How Prismecs Delivers MRO Services
Prismecs follows structured engineering from asset review through repair execution and verified return to service, meeting defined scope, schedule, quality, and documentation requirements.
Why Operators Choose Prismecs for MRO Support
Prismecs combines technical coordination, OEM-neutral sourcing, and field execution management to reduce outage duration, repeat findings, overhaul costs, and long-term asset performance risks.
Single Point of MRO Coordination
Instead of managing separate OEMs, repair shops, suppliers, and technicians, operators choose Prismecs as one accountable coordinator for managing scope, schedule, quality, logistics, and documentation.
OEM-Neutral Repair Sourcing
Prismecs compares OEMs, authorized workshops, and qualified providers on various factors, securing competitive cost and faster turnaround while maintaining quality, warranty, and compliance requirements.
Reduced Downtime Through Exchange Programs
Hot section and rotatable exchange programs swap modules on site and return units to service while removed components are repaired offline, reducing planned outage duration and restoring generation capacity faster.
Structured Inspection and Lifecycle Planning
Every inspection generates documented condition data for lifecycle planning. Prismecs tracks component hours, repair history, and degradation trends, ensuring future CI/HGP/MI scopes reflect actual asset condition.
Transparent Gas Turbine Overhaul Cost Management
Prismecs provides technical and commercial comparison of repair solutions before execution. Operators see total project costs for field execution, workshop repair, parts, logistics, and contingency upfront.

Frequently Asked Questions
A hot gas path inspection examines the turbine components exposed to the highest operating temperatures, including first and second stage blades, nozzles, and shrouds. It is typically performed at a defined interval of factored fired hours and assesses thermal wear, coating degradation, cracking, and oxidation to determine whether components can be repaired or must be replaced.
A combustion inspection focuses on fuel nozzles, liners, crossfire tubes, and transition pieces. A hot gas path inspection adds the turbine blades, nozzles, and shrouds to that scope. A major inspection is the most extensive of the three inspection types and may require extensive disassembly for detailed condition assessment, repair, or component replacement.
A hot section exchange replaces the high-temperature turbine module with a pre-overhauled unit on site, allowing the power plant to restart in days rather than weeks. The removed module is then sent to a qualified workshop for offline repair and refurbishment, eliminating the need to wait for component-level repairs before returning the unit to service.
Gas turbine overhaul cost depends on the turbine model, inspection type, component condition, required repairs, and whether field repair, workshop refurbishment, or component exchange is selected. Prismecs provides a technical and commercial comparison of available options before execution, so operators can evaluate the full scope and cost before committing.
Prismecs coordinates inspection, repair, refurbishment, and overhaul activities through OEMs, authorized workshops, and qualified specialist partners. Proprietary repair limits, component life decisions, and design approvals remain with the applicable OEM or authorized repair provider. Prismecs manages the complete scope as a single point of contact, coordinating the technical work, specialist partners, quality, schedule, and documentation through final handover.
