First Wärtsilä Modular Block destined for Resolute’s Syama gold mine

Wärtsilä has announced the first order of its innovative new Wärtsilä Modular Block solution for power generation to Aggreko, with four Wärtsilä Modular Block enclosures – with one medium-speed Wärtsilä 32 engine in each – to provide 40 MW of energy to Resolute Mining’s Syama gold mine, in Mali.

The Modular Block order was placed by Aggreko in November 2019 and the contract is the first one signed under the cooperation agreement between Wärtsilä and Aggreko, announced in June.

The pre-fabricated, modular, and expandable enclosures feature medium-speed Wärtsilä 32 and 34 family engines, can run on a variety of fuels and can operate as a re-deployable power generation solution, according to Wärtsilä. “The Wärtsilä Modular Block solution can be installed in a matter of weeks, and can be expanded to accommodate increased energy needs. Similarly, it can be dismantled and relocated to alternative locations as and when required, making it highly suited to temporary power generation,” Wärtsilä said.

Resolute announced last month that it was partnering with Aggreko on this power solution, saying that the thermal element of the project was expected to be implemented in partnership with Wärtsilä using its new Modular Block technology and design.

“The Wärtsilä Modular Block solution will replace the existing diesel generators currently powering the mine,” the company said, adding that the high efficiency of the engines should result in “substantial monthly savings” in fuel costs.

It added: “Fast-starting and load following capabilities will facilitate the integration of renewables into the mine’s energy system. The mine will be powered by a reliable, flexible and affordable solution, which will help to enhance the mine’s environmental impact.”

Three Wärtsilä Modular Blocks, providing a total of 30 MW of power will be installed next to the existing power station in 2020. The fourth 10 MW Modular Block will be installed in 2022, with an option to add a fifth 10 MW unit to the power plant.

Stephane Le Corre, Strategy and Development Director at Aggreko, said: “The Wärtsilä Modular Block supports our technology investment strategy and, when included as part of a hybrid solution, has enabled us to offer Resolute an extremely cost-effective solution for 16 years.”

Jean Nabb, Director, Strategic Partnerships, Wärtsilä Energy Business, said: “The Wärtsilä Modular Block solution opens up exciting new opportunities, both for permanent and rental electricity generation. We are delighted to be partnering with Aggreko in this rapidly growing market, and this first order is encouraging for the future success of our cooperation.”

Under the agreement between Aggreko and Wärtsilä, Wärtsilä will provide the technology and design for the core power generation equipment, with Aggreko incorporating Wärtsilä’s Modular Block enclosure and power generation within its Rental/Power Solutions sales offering.
