TEPCO Begins Using IoT to Optimize Efficiency of Its Thermal Power Plants

TEPCO, known more formally as Tokyo Electric Power Company Holdings (TEPCO), and TEPCO Fuel & Power, Inc., are leverage the Internet of Things (IoT) with a new remote optimizatoin center to increase fuel efficiency and optimize other 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 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 per unit a year. Also, by remotely detecting symptoms of nonconformance, the technology optimizes power station operation and maintenance (reduce outages by 10-20%).

The Data monitoring and Analyzing 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. In collaboration with some of the world's leading IoT companies, the technologies include:

Within the cooperation of domestic and global industry leaders, TEPCO studied software provided by these companies and developed platforms. TEPCO plans to strengthen these tools, and will offer these technologies and services to other power operators overseas.

Both companies will comprehensively provide operational support services and platforms utilizing DAC to international power operators including Southeast Asia.
