DUBLIN, IRELAND (September 8, 2025) – Electricity Supply Board (ESB) and GE Vernova (NYSE: GEV) have unveiled a comprehensive modernization and life extension initiative for the Dublin Bay power plant. The project is designed to boost operational performance, improve reliability, and increase electricity output, while aligning with ESB’s Net Zero by 2040 decarbonization strategy.

Under a new long-term service agreement, GE Vernova will deploy its advanced GT26 High Efficiency (HE) upgrade alongside SEMIPOL™ solutions, including Static Excitation Equipment (SEE) and a Startup Frequency Converter (SFC). Completion of the upgrade is scheduled for 2026.

Originally commissioned in 2002, the Dublin Bay facility currently produces up to 415 MW using a single-shaft GT26 gas turbine. The planned enhancements are expected to deliver:

• Up to 30 MW of additional capacity—enough to power approximately 30,000 homes annually
• Efficiency improvements of up to 1.8% at baseload, reducing CO₂ emissions by around 5%
• Strengthened grid stability through upgraded excitation and frequency control systems
• Lower carbon intensity and readiness for future hydrogen fuel blending

Arkadiusz Galant, Dublin Stations Manager at ESB, emphasized that while the plant is already among the company’s most efficient, the upgrade will further strengthen its role in delivering reliable, low-emission power. He noted that the project will enable increased electricity generation while supporting long-term sustainability goals and potential hydrogen integration.

Joseph Anis, President & CEO of GE Vernova’s Gas Power business for Europe, the Middle East, and Africa, highlighted the project as a continuation of the longstanding partnership between GE Vernova and ESB. He stated that the integration of GT26 HE and SEMIPOL™ technologies will enhance output and efficiency while ensuring the flexibility required for Ireland’s evolving energy landscape.

Advanced Technology Upgrades

The GT26 HE upgrade, introduced in 2019, incorporates innovations from GE Vernova’s F- and H-class turbine platforms. These include additive manufacturing components and advancements in aerodynamics, materials science, and combustion technology. Together, these improvements optimize fuel consumption, increase power output, and extend maintenance intervals.

Globally, more than 100 GT26 units are in operation, delivering approximately 37 GW of capacity. These turbines are capable of operating on fuel blends containing up to 40% hydrogen, supporting future decarbonization pathways.
