Lindsayca, the contractor developing the integrated gas processing facility under Guyana’s Gas-to-Energy (GtE) project, said it installed three heat-recovery steam generator (HRSG) bypass stacks at the Wales, West Bank Demerara site.
The U.S.-based contractor, in a LinkedIn post on May 29, said that “three of the four HRSG Bypass Stacks have now been successfully positioned, with the fourth and final stack scheduled for installation this week”.
The contractor added that “activity continues across the site as progress advances on multiple fronts”.
The bypass stacks form part of the project’s heat recovery steam generator (HRSG) system at the 300-megawatt gas-fired power plant. HRSG systems are commonly used in combined-cycle power plants to capture exhaust heat from gas turbines and convert it into steam for additional electricity generation.
According to the industrial engineering company Forney Corporation, HRSG bypass systems help operators control exhaust gas flow between the turbine and the steam generation unit, improving operational flexibility and reducing downtime during inspections and maintenance.

Guyana’s Gas-to-Energy project is designed to use associated natural gas from ExxonMobil Guyana’s offshore Stabroek Block operations to generate lower-cost electricity and support industrial development.
The first phase includes a natural gas liquids separation plant and the 300-megawatt power facility at Wales.
The Guyana government has stated that the first gas turbine is expected to come online by the end of 2026, with full commissioning of all gas turbines targeted for the first quarter of 2027. Combined-cycle operations are expected by June 2027.
