TEPCO launches IoT thermal plant optimization centre

Tokyo Electric Power Company expects to save millions of dollars a year in fuel costs at its thermal power plants thanks to a new IoT optimization centre.

The remote optimization centre has been established by Tokyo Electric Power Company Holdings (TEPCO) and TEPCO Fuel & Power to increase the fuel efficiency and other operations of its thermal plants.

The centre is the result of testing that started in 2015 and will now be developed into operational support services for the thermal plants of other electricity producers in Japan and overseas. TEPCO says the centre’s projected annual revenue is $46bn 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” said Seiji Moriya, president of TEPCO Fuel & Power. “TEPCO intends to enhance its presence as a global O&M company.”

Moriya said that by using IoT technology, the effort has improved power generation efficiency, resulting in decreasing fuel costs up to $651,000 per unit a year. Also, by remotely detecting symptoms of non-conformance, the technology optimizes power station operation and maintenance with reduced outages of 10-20 per cent.

A data monitoring and analyzing centre was added to the trials in January 2017 and has confirmed operational improvements at TEPCO Fuel &Power’s thermal plants at Hitachi-Naka, Chiba, Futtsu and Shinagawa.

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.
