Hitachi Energy deploys the first digital substation in East Java

Indonesia: Hitachi Energy has delivered a state-of-the-art 150 kV digital substation in East Java, Indonesia.

This will help Indonesian utility PT Perusahaan Listrik Negara (PLN Persero) ensure reliable power and better support economic development in East Java, as well as contribute to broader long-term sustainability goals.

The East Java and Bali Development Central Unit (UIP JBTB) substation connects the 200 ha Sidoarjo Industrial Estate (KIS), which includes large manufacturing companies, to PLN’s grid as part of Indonesia’s efforts to build resilient infrastructure and realize the benefits of industry 4.0.

The increased reliability the digital substation brings will help drive further economic growth and investment in the East Java Province, which makes up almost 15 % of national gross domestic product, the second highest contributor after the capital, Jakarta.

The digital substation also supports Indonesia’s transition to a low-carbon future by seamlessly integrating renewable energy and contributing to the decarbonization of the region’s electricity network. The project was launched and completed during a challenging 2020.

“This project is another example of how digitalization is playing a key role in shaping power systems and reaffirms our position as a partner of choice for advancing a sustainable energy future in Indonesia,” said Massimo Danieli, Managing Director Grid Automation at Hitachi Energy. “As a trusted partner to PT PLN (Persero), the nation’s utility company, we will continue to support the development of the country’s energy infrastructure and its digital transformation.”

The brand-new substation at KIS is based on the latest communication protocols for control, protection and automation. The use of a process bus communication network enables continuous bidirectional exchange of digital data between primary equipment, protection equipment, the SCADA system, and the regional control centre.
