Contract awarded for IoT services using EtaPRO™ for Indonesian geothermal power plant

KAWASAKI, Japan, August 23, 2022 /PRNewswire/ — Toshiba Energy Systems & Solutions Corporation (hereinafter “Toshiba ESS”), through its Indonesian subsidiary Toshiba Asia Pacific Indonesia, active in the energy and infrastructure sector, has entered into an agreement with indonesia PT Geo Dipa Energi (Persero) (hereafter “GDE”) for an IoT service aimed at improving the utilization rate of the electricity production facilities of its geothermal power plant in Patuha[1]. This service uses IoT and AI technologies, including predictive fault diagnosis and plant performance monitoring. This contract is the group’s first commercial application of IoT services for geothermal power plants.

This service represents a commercial version of what was implemented as a NEDO (New Energy and Industrial Technology Development Organization) demonstration project for this power plant in October 2019[2]. The demonstration project verified the effectiveness of the company’s IoT-based predictive fault diagnosis technology and helped secure the contract. The system provided by this service uses EtaPRO™[3]a software suite acquired by Toshiba ESS last year, and represents the world’s first commercial application of EtaPRO™ to a geothermal power plant.

This system stands out technologically for its use of AI to analyze in real time the operating data of the power plant obtained from various sensors and detect signs of anomalies that can cause problems during normal operation. In doing so, it reduces the number and duration of plant outages; a demonstration project conducted by NEDO showed that it was able to reduce the occurrence rate of problems by more than 20%. Another important feature is the ability to detect signs of anomalies in conditions specific to geothermal power plants, such as the unstable state of the steam entering the turbine, which is not the case with thermal power plants.

In Indonesia, total installed power generation capacity was about 62 GW in 2020, with coal-fired power generation accounting for about half of that total. Meanwhile, in line with the Paris Agreement, the Indonesian government has pledged to reduce greenhouse gas emissions by 29% by 2030, the Electricity Business Plan (RUPTL) says that geothermal power generation will account for about 3.4 GW (about 8%) of the 40.6 GW of power generation capacity to be added by 2030[4]. Toshiba ESS has delivered equipment to several geothermal power plants in Indonesia. He will be proactive in proposing the IoT solutions that enable optimal operation that will help solve the problems encountered by current and future individual customers.

By deploying this service worldwide, Toshiba ESS aims to reduce the customer’s cost of power generation by helping to improve power plant utilization rates, thereby promoting the spread of geothermal power generation and contributing to achieve carbon neutrality.
