TEPCO boosts plants efficiency with IoT optimisation center


Tokyo Electric Power Company Holdings (TEPCO) and TEPCO Fuel & Power, Inc. are utilising a new internet of things (IoT) based optimisation center to increase the fuel efficiency and operations of its thermal power plants.

The effort is the result of testing that began in 2015, and will be developed into operational support services for the thermal power plants of other electricity producers both in Japan and overseas.

The center’s projected annual revenue is 5 billion JPY ($47 million) within three years.

“Embracing IoT technology to improve our technological services make it possible to provide value-added services for our customers in terms of maintaining thermal efficiency and improving power generation availability,” says Seiji Moriya, President of TEPCO Fuel & Power, Inc.

“TEPCO intends to enhance its presence as a global O&M (operation and maintenance) company.”

By using IoT technology, the effort has improved power generation efficiency resulting in decreasing fuel costs up to 70 million yen ($658, 000) per unit a year. Also, by remotely detecting symptoms of non-conformance, the technology optimises power station operation and maintenance (reducing outages by 10-20%).

The Data monitoring and Analysing Center (DAC) was added to the trials in January 2017, and has confirmed operational improvements at TEPCO Fuel & Power’s thermal power plants at Hitachi-Naka, Chiba, Futtsu, and Shinagawa.

TEPCO worked with leading software companies to create a unique and tailored IoT platorm that includes a number of components such as; a cloud platform, data infrastructure, early anomaly detection and performance management systems.

The IoT centre was developed in collaboration with some of the world’s leading IoT companies, including OSIsoft, Amazon Web Service, BHGE Bently Nevada and Curtiss-Wright.

By utilitising DAC, both TEPCO and TEPCO Fuel & Power, Inc will comprehensively provide operational support services and platforms to international power operators, including Southeast Asia.
