The renewal of technology group Wärtsilä’s operations and maintenance (O&M) agreement with QIT Madagascar Minerals (QMM), which is part of the Rio Tinto group, has been expanded to include a decarbonisation agreement.

Wärtsilä says the agreement is a groundbreaking offering in the energy sector and allows for optimising all of the assets in the microgrid, including renewable-energy use, thereby not only reducing emissions but also producing notable cost savings.

The continued O&M agreement covers QMM’s 24 MW engine power plant located at the company’s ilmenite mineral sands mine at Fort Dauphin in south-eastern Madagascar. The order was booked by Wärtsilä in June.

Key elements of the agreement include optimised dispatch of the plant’s six Wärtsilä 32 engines and QMM’s battery energy storage and renewable assets with Wärtsilä’s GEMS Digital Energy Platform.

The GEMS software uses machine learning technology to optimise multiple energy generation assets and ensure maximum use of renewable energy.

“The O&M agreement with Wärtsilä has been in place since 2008 and we have been pleased with Wärtsilä’s performance. The reliability and efficiency of the power plant are critical to our operations and we are, therefore, excited to extend this agreement.

“The renewed agreement allows us to take advantage of Wärtsilä’s competence in power system optimisation and use renewables in the most efficient way, supporting Rio Tinto’s decarbonisation objectives and sustainable mining vision,” says QMM integrated operational services director Jean-Francois Richer.

Wärtsilä explains that the hybrid power plant supplies the electricity required to operate the mine and also to the nearby town of Fort Dauphin.

“Our decarbonisation agreement is taking energy optimisation to a new level by enabling cost savings, a reduced environmental footprint and higher efficiency. What is more, the partnership is outcome-based with mutual incentives. This is the way forward in making decarbonised operations a viable reality,” says Wärtsilä Energy decarbonisation services director Christoffer Ek.

“This agreement strengthens our long-lasting partnership with QMM. We are delighted to continue to support their operations, both with our technology and our regional service network. By working in close cooperation with the customer, we are able to ensure a reliable and sustainable power supply to the mine,” adds Wärtsilä Energy Africa and Europe VP Kenneth Engblom.
