Guyana has reached a milestone in its Gas-to-Energy (GtE) project with the appointment of Siemens Energy as operator of the country’s flagship 300MW combined-cycle power plant
The GtE project is designed to transform offshore natural gas resources into reliable, affordable power and support long-term economic development.
Announced in June 2026, the agreement advances one of the Caribbean’s most ambitious energy infrastructure initiatives, placing natural gas as a catalyst for energy security, industrialisation, and a diversified energy mix. The power plant is expected to begin operations in early 2027, with natural gas supplied by the ExxonMobil-operated Stabroek Block.
The 300MW facility is only one component of the GtE development, which also includes a Natural Gas Liquids facility and upgraded transmission infrastructure supplied by gas from the Liza field. These interconnected assets are expected to double Guyana’s electricity generation capacity, reduce electricity costs by 50%, improve grid reliability, reduce dependence on imported liquid fuels, and create a foundation for a domestic gas value chain that can support industrial expansion, attract new investment, and strengthen national competitiveness.
The project also represents a cornerstone of the country’s Low Carbon Development Strategy 2030, which integrates responsible natural gas development with renewable energy expansion to build a cleaner, more resilient energy system.
Speaking in January 2026, Prime Minister Mark Phillips described natural gas as “a reliable, efficient, and lower-emitting source of energy” capable of meeting the country’s rapidly growing electricity demand while supporting long-term sustainable development.
Guyana has begun planning the next phase of its gas development strategy through the proposed Berbice GtE project in Region Six, aiming for completion by 2030. The facility is expected to expand domestic gas utilisation, reinforce the country’s gas value chain and create new opportunities for engineering companies, technology providers and local businesses.
Continued upstream investment is ensuring sufficient gas resources to support Guyana’s growing domestic market. ExxonMobil is also advancing the Longtail development, which will combine the Longtail, Tripletail, and Turbot discoveries into one of Guyana’s largest offshore gas projects.
The development has the potential to produce 1.5 billion cubic feet of gas per day and 290,000 barrels of condensate per day over an estimated 30-year operating life, supported by an FPSO vessel with a two million barrel storage capacity.
Exploration campaigns such as the Barreleye-3 well, running through August 2026, are continuing to target additional discoveries to further expand Guyana’s domestic gas supply and strengthen future commercialisation opportunities.
The role of natural gas in Guyana’s energy transition will be a central focus at Caribbean Energy Week 2027, under the theme ‘unlocking the Caribbean energy corridor: oil, gas, LNG & investment for a new global hub’. The event will examine how gas investments are helping to reinforce energy security, support industrial development, and create new commercial opportunities across the Caribbean energy value chain.
Caribbean Energy Week 2027 will host its Guyana in-country launch at the Guyana Marriott Hotel in Georgetown on September 1, 2026, bringing together government officials, investors, operators, and industry stakeholders for an early look at the opportunities, priorities, and partnerships shaping Guyana’s energy future.
Latest developments emphasise Guyana’s strategy of leveraging its estimated 17 trillion cubic feet of recoverable natural gas resources to reinforce energy security, diversify its energy mix, and accelerate economic growth. By positioning natural gas as a complement to renewable energy expansion, Guyana is seeking to utilise its gas resources as a foundation for industrial development, improved energy resilience and a broader low-carbon transition.
