Hitachi Energy’s power quality solution
October 2025
Electrical Power & Protection
Hitachi Energy has announced the deployment of its power quality solution to connect Tanzania’s leading gold producer, Geita Gold Mine (GGML) securely to the national grid, which comprises 45,5% renewable energy sources. The project replaced 80% of the fossil-fuel gensets used by GGML for power generation, and is expected to reduce the site’s carbon emissions by at least 50 kilotons of CO2 per annum.
AngloGold Ashanti, the owner of GGML, collaborated with the government of Tanzania, its power utility Tanzania Electric Supply Company (TANESCO), and Hitachi Energy to execute the project.
As part of the project, Hitachi Energy delivered a state-of-the-art power electronic converter that stabilises the mine’s connection to the grid, featuring a PCS 6000 STATCOM system. The system’s performance is further optimised through MicroSCADA, which provides crucial real-time monitoring and control.
With extensive project execution capabilities, Hitachi Energy engaged with partners in Tanzania, providing supervision and training to contractors, fostering skills development and contributing to community upliftment. The company strengthened local capacity through these efforts, ensuring long-term success and sustainability while delivering cutting-edge technology.
“We are proud to support Geita Gold Mine Limited in this landmark achievement. AngloGold Ashanti’s unwavering commitment to sustainability and climate resilience across their business, value chain and communities sets a remarkable standard in the industry,” said Mohamed Hosseiny, managing director at Hitachi Energy in Africa. “It is reassuring that our pioneering technologies and solutions are advancing a sustainable energy future for all.”
The project is a testament to Hitachi Energy’s expertise in providing solutions, executing projects and developing pioneering technologies. The PCS 6000 STATCOM system was pre-assembled, tested to the highest standards and shipped as a containerised package for fast installation on site. Its compact design and adaptability to harsh mining environments make it a compelling solution for industrial and remote grid applications.
Electrification solutions like the STATCOM system are vital to accelerating the global energy transition. By delivering innovative technology to high-impact markets, Hitachi Energy empowers the world’s energy system to be more sustainable, secure, resilient and affordable.
