Business Area


Mitsubishi Power is leading the development of the smart power plant of the future with TOMONI, a suite of intelligent solutions enabled by decades of O&M and plant knowledge. Our solutions use advanced analytics and are driven by customer collaboration to deliver powerful financial and environmental advantages.


TOMONI is driven by collaboration

TOMONI, a Japanese word meaning "together with," reflects the emphasis Mitsubishi Power places on collaborating with customers to solve their unique challenges. Mitsubishi Power works together with customers, partners and society to deploy solutions that support the decarbonization of energy and deliver reliable power everywhere.

 TOMONI means "together with"

TOMONI is supported by our extensive accumulated knowledge

TOMONI is supported by Mitsubishi Power's extensive experience and knowledge in technology, R&D development, design, manufacture and maintenance of power generation equipment and total power plant systems.

Solution architecture

TOMONI systems can be customized to work with user's existing platform to provide benefits of O&M Optimization, Performance Improvement and Flexible Operation.


For over 20 years, Mitsubishi Power has been steadily expanding the capabilities of its TOMONI HUB (Analytics and Performance Center) and has been successfully providing remote monitoring and increasing the use of advanced analytics to make power plants more reliable and profitable. TOMONI HUB provides connected software and services that monitor and provide real-time early warning of impending issues or needed corrective action to avoid unit trips or load reductions, reduced energy efficiency losses and avoidance of unnecessary maintenance.

Notes: TOMONI is a trademark of Mitsubishi Heavy Industries, Ltd. The service name for Chinese market is TOMONICHN.


Netmation® Protect Pack

Netmation® Protect Pack (NPP) is a security solution that protects the power plant control system DIASYS Netmation from the threat of cyber-attacks. NPP helps power producers meet the requirements of various cyber security standards and keeps the software up-to-date with regular security patch updates. It enables power plants to avoid the possible unplanned downtime, equipment damage, financial losses and penalties that can arise when they fail to meet cybersecurity standards.

GT Remote and Automatic Combustion Tuning

A new service from Mitsubishi Power allows combustion tuning to be performed remotely via a TOMONI HUB, thereby satisfying the power plant operator’s requirements while eliminating the need to send a technical adviser to the power plant.

IGV (Inlet Guide Vane) Optimization

With the intermittent nature of renewable electricity generation technology and the ever-changing demands of the grid, IGV (Inlet Guide Vane) Optimization is a digital solution that can help to meet these challenges. It is a control modification that closes the gas turbine inlet guide vanes in a controlled way to reduce air flow at partial loads and thus increase exhaust temperature while minimizing emissions.

CBM (Condition Based Maintenance)

With the rise of decarbonization and renewable energy, we need to optimize maintenance intervals to reduce Gas Turbine Combined Cycle (GTCC) maintenance costs and to improve capacity value and opportunities to sell electricity. By compiling extensive accumulated experience, big data and knowledge in Mitsubishi Power, CBM optimizes maintenance intervals and maximizes GTCC asset value.

Block Insulation Package

Mitsubishi Power's Block Insulation Package comprises modular insulating blocks and an intuitive guide system. The package enables gas turbine operators to attach and remove insulation more efficiently, thereby generating significant time and labor savings.

Trip Prevention Package

While the prediction of power plant malfunctions tend to focus on diagnosing anomalies in gas turbines, failure on start-up is actually often the result of an issue with an associated system. By offering holistic diagnosis and support for not only turbines but also their associated systems, Mitsubishi Power's Trip Prevention Package, which is part of the TOMONI intelligent solution, helps to avoid failures on start-up.

Turbine Cooling Air Optimization

"Turbine Cooling Air Optimization" improves the performance of gas turbines in power plants. It improves the power generation efficiency of air-cooled gas turbines through control of the turbine cooling air (TCA) fans to optimize the rotor cooling air (RCA) temperature. The technology has already been proven on 14 commercially operating units (as of Dec. 2021).
