Flexible Long-Term Agreements

At Hanwha Power, we deliver flexible, cost-effective Long-Term Service Agreements (LTSAs) for GE, Siemens, and Mitsubishi B/E and F-class gas turbines. Our agreements are designed to help plant operators reduce lifecycle costs, increase asset reliability, and improve long-term planning through structured service, support, and upgrades.

Whether you need a full-scope solution or a flexible pricing structure, our LTSA options are built to adapt.

Key Benefits:

  • Cost Control: Predictable maintenance costs and fewer unplanned outages.
  • Extended Life: Upgrades and repair solutions to improve part durability and performance.
  • Efficiency Gains: Integrated retrofits and optimization packages like FlameSheet™, LEC ultra-low emissions systems, and GTOP.

Service Agreements FAQs

Hanwha Power service agreements cover GE, Siemens, and Mitsubishi B/E-class and F-class gas turbines. This includes GE 7F, 9F, 6B,7B/EA, 9E, Siemens/Westinghouse 501F, and other heavy-duty frames. Agreements are tailored to each customer’s specific fleet, operating profile, and financial strategy.

What gas turbine frames do Hanwha Power service agreements cover?
How is a Hanwha Power LTSA different from an OEM service agreement?

Hanwha Power’s LTSAs offer flexible, modular pricing structures rather than bundled full-scope contracts. Operators can choose the level of coverage that matches their needs, from full-scope LTA to parts-only Frame Agreements. Hanwha Power agreements include access to proprietary upgrade technologies like FlameSheet, LEC III, and GTOP, which can be integrated into the service plan to improve performance and extend inspection intervals. Hanwha Power does not require operators to purchase all parts and services exclusively through Hanwha Power.

Does a Hanwha Power service agreement include remote monitoring?

Yes. Hanwha Power’s Long Term Agreement (LTA) includes 24/7 remote monitoring and diagnostics through Hanwha Power’s Intelligent Data platform. Remote monitoring is available as an optional add-on for LTMA and Frame Agreement tiers. The Intelligent Data platform provides real-time performance tracking, predictive maintenance alerts, and emissions monitoring.
