GEV and ESB to Modernize Dublin Bay Power Plant to Help Boost Efficiency and Grid Reliability

Electricity Supply Board (ESB) of Ireland and GE Vernova (NYSE: GEV) have announced a major life extension and modernization project for the Dublin Bay power plant, aimed at enhancing performance, reliability, increasing output, and supporting Ireland’s energy transition goals in line with ESB’s Net Zero by 2040 carbon emissions strategy.

Under a new contractual service agreement, GE Vernova will implement its GT26 High Efficiency (HE) upgrade along with its SEMIPOLTM technology for Static Excitation Equipment (SEE) and Startup Frequency Converter (SFC). This life extension project is expected to be completed in 2026.

Commissioned in 2002, the Dublin Bay facility currently generates up to 415 Megawatts (MW) using a single -shaft GT26 gas turbine.

The major life extension project is expected to deliver:

• Up to 30 MW of additional power, which is the power needed to supply the equivalent of approximately approximately 30,000 Irish homes annually
• Efficiency gains of up to 1.8% at baseload, leading to 5% carbon dioxide (CO2) reduction
• Improved grid stability through advanced excitation and frequency conversion systems
• Lower carbon intensity, supporting ESB’s decarbonization strategy and enabling future use of hydrogen fuel blends.

“Although Dublin Bay is already one of our most efficient plants, we saw an opportunity in having an even more important role in delivering our Net Zero carbon emissions strategy by further enhancing its performance, reliability and sustainability.” said Arkadiusz Galant, Dublin Stations Manager, ESB. “Our life extension project in 2026 will help us to deliver more power allowing us to provide electricity for Irish households over the next decade while being more efficient with lower emissions and enabling possible future hydrogen blends.”

“This project builds on our long-standing partnership with ESB,” said Joseph Anis, President and CEO of GE Vernova's Gas Power business in Europe, Middle East, and Africa “The GT26 HE upgrade and SEMIPOL™ technologies will not only increase output and efficiency but also provide the flexibility and reliability needed to support Ireland’s evolving energy landscape.”
