German company Siemens Energy is preparing to operate and maintain the 300-megawatt (MW) combined-cycle power plant, which is part of the larger Wales Gas-to-Energy project on the West Bank of Demerara.
In a release from the Office of the Prime Minister, it was noted that the arrangement with Siemens Energy includes a five-year operations period, with an option for renewal, as well as a 20-year long-term maintenance programme for the turbines. Siemens Energy will also hold overall responsibility for coordinating operations and maintenance across the integrated Gas-to-Energy facility, with the NGL plant operations integrated into that framework.
The Siemens Energy team is currently in Guyana to advance mobilisation and technical coordination ahead of the commencement of operations. Guyana's Prime Minister Brigadier (Ret'd) Mark Phillips told the team that the effective management of the facility will be integral to realising the wider benefits of the Gas-to-Energy project for Guyanese households and businesses, including improved electricity supply and reduced energy costs.

"Your presence in Guyana at this stage is important. The focus now is on the technical work, mobilisation and preparations required to ensure that the plant is ready for start-up and, importantly, that it operates safely, reliably and efficiently. You bring the expertise that is critical at this stage of the project as we work towards delivering stable and reliable electricity to the people of Guyana," he was quoted as saying in the release.
About 50 million cubic feet per day (mcf/d) of gas will be supplied to the Wales Gas-to-Energy project to fire the 300-megawatt power plant, providing energy to the national grid and powering new industrial developments. Operations are expected to commence in early 2027.
Additionally, a Natural Gas Liquids (NGL) processing plant will treat the gas, removing liquids such as propane and butane for commercialisation.
This long-anticipated project has been touted as one that will slash the cost of electricity in half while satisfying Guyana's growing demand for energy.
Beyond Siemens Energy, some of the other known stakeholders in the project include:
- ExxonMobil — the operator in the Stabroek Block, responsible for supplying the natural gas through the pipeline
- Lindsayca — the primary engineering, procurement and construction contractor for the integrated natural gas and power plant facilities at Wales
- Phoenix Park Gas Processors Limited — alongside GuyGas, this Trinidadian company will operate and maintain the NGL plant
