Background

The energy transition calls for more affordable and cleaner electricity, driving a shift in power generation from fossil-based sources to variable renewable energy (VRE) technologies. However, thermal generation assets remain essential to ensure grid stability and energy security. While future energy outlooks project a fairly constant thermal generation capacity, the utilisation factor of these assets is expected to decline significantly, potentially leading to revenue erosion. At the same time, fixed and maintenance costs are likely to rise, creating pressure on asset profitability and discouraging investments in new thermal projects.

To adapt, thermal plants must become more flexible, with designs that can accommodate frequent start/stop operations. Understanding the evolving economics, market mechanisms, and regulatory frameworks is critical for stakeholders across the turbomachinery value chain.

To support this transition, the ETN External Taskforce on the “Profitability of Thermal Assets” is launching an online webinar series consisting of six interactive sessions. These will take place from September 2025 to March 2026, providing participants with a structured introduction to the economics of thermal power assets and electricity markets.

Abstract of the second seminar

The second seminar of the ETN Global series on “Profitability of Thermal Assets”, titled “Basic Economics of Power Plants”, will take place on 15 October from 11:00 to 12:30 (CET). 

The seminar will take place during the ETN Global International Gas Turbine Conference, which will be taking place on 14 and 15 October 2025 in Brussels, Belgium.

This session will explore regional energy needs and the evolving role of gas turbines in supporting low carbon energy transitions across various regions. While many countries share similar decarbonisation objectives, the actual pathways and timelines differ significantly due to local resource availability, policy frameworks, and security of supply priorities.

Drawing on perspectives from Europe, Middle East and Africa, speakers will highlight how regional realities shape investment decisions, technology adaptation and market design. The session will showcasing how flexible, dispatchable, and low-emission gas turbines can be adapted and integrated into diverse energy systems, either complementing renewables, supporting industrial growth, or ensuring reliability in regions with rapidly rising demand.
