Wärtsilä engines to deliver reliable power for Guyana gold mine

Technology group Wärtsilä will supply the equipment for a power plant needed to operate a new gold mine in Guyana. The Oko West Gold Project is a new gold discovery in northwest Guyana located approximately 95 km west of Georgetown. It is a remote region where tropical conditions pose significant challenges. Wärtsilä’s engines were specifically chosen for their proven ability to operate reliably under these environmental conditions. The order was placed by GMIN Ventures Guyana Inc, a subsidiary of Canada based G Mining Ventures, a public gold mining company listed on the Toronto Stock Exchange (TSX), and was booked by Wärtsilä in Q3 2025.

Once fully operational, the 56MW power plant will operate with all six Wärtsilä 32 engines. It will provide the power necessary for maintaining the mine’s production under all circumstances. The proven efficiency and reliability of the Wärtsilä 32 engine will, therefore, play a key role in supporting production schedules. The project is expected to create around 1,500 jobs for local communities.   

“Wärtsilä’s proven engine technology is designed for high ambient temperatures and limited water supplies, which makes our engines the practical solution to providing power for mining operations in remote locations. We are delighted to once again deliver the support needed for a mine to be able to operate,” comments Tganni Louisy, Project Sales Director, EPP at Wärtsilä Energy.

GMining Services, sister company of G Mining Ventures, serves as the project’s consultant and comes with prior consulting experience on mining projects where Wärtsilä has also been selected to provide power solutions. The power plant is expected to be commissioned and fully operational by the second half of 2027.
