Project Overview:
Atlantic LNG operates 28 Frame 5 gas turbine compressors in a simple cycle configuration. CADA is currently developing a preliminary design to enhance energy efficiency by integrating an Organic Rankine Cycle (ORC) bottoming system. This innovative retrofit has the potential to generate approximately 500 MW of additional power, resulting in projected efficiency savings exceeding USD 89 million.

Technical Approach:
The proposed solution involves retrofitting each gas turbine with a high-efficiency heat exchanger. These exchangers will capture exhaust heat and transfer it to a working fluid, which will then be routed to ORC units for power generation—without the need for additional fuel input.

Sustainability and Operational Benefits:
The additional power generated is classified as renewable, effectively displacing the fuel otherwise required for plant electricity needs. This contributes to a reduction in greenhouse gas emissions and qualifies the project for carbon credits under baseline improvement metrics.

The ORC system offers several operational advantages:

• No additional staffing requirements: Unlike traditional steam plants, ORC units do not require stationary engineers.
• Compact footprint: The system occupies significantly less space.
• Flexible installation: Waste heat can be transported to optimally located ORC units for efficient power generation.
