The Flexibility Gap: Is Europe's Grid Ready for a Future Without Russian Gas and with Peak Renewables?

05.08.2025

Europe’s energy system is entering an era of unprecedented challenges. The phase-out of Russian energy resources and the rapid growth of renewable energy sources (RES) are creating a “perfect storm,” leading to a systemic flexibility gap—a critical issue that threatens grid stability and energy security across the continent.

This challenge will be the central theme of discussion at the Energy Club’s international forum, “Balancing Europe’s Energy System: Challenges, Solutions, and Prospects,” taking place on October 9, 2025, in Vienna.

What is the Core of the Problem?

“Flexibility” is the ability of an energy system to react quickly to changes in electricity production and consumption, maintaining balance in real time. In the past, this function was primarily provided by traditional power plants (gas, coal), which could rapidly increase or decrease their generation.

Today, the situation has changed dramatically for two reasons:

• The Phase-Out of Fossil Fuels: Europe is gradually decommissioning dispatchable power plants that acted as a “shock absorber” for the energy system.
• The Rise of RES: Solar and wind power plants produce energy intermittently, creating significant volatility that must be compensated for by other means.

The result is a dangerous gap between the growing need for flexibility and the available tools to provide it. The consequences of this deficit are already visible today in the form of extreme price volatility in balancing markets and an increased risk of systemic failures.

Where Can We Find Solutions?

Without new technologies and market approaches, the further integration of renewables and the stability of the European energy system are impossible. Comprehensive solutions are needed, including:

• Large-scale deployment of Battery Energy Storage Systems (BESS).
• Smart Grids and the use of Artificial Intelligence for forecasting and management.
• New market models that incentivize flexibility services from consumers and distributed generation.

It is precisely to find answers to these strategic questions that the Energy Club is gathering leading European experts in Vienna.

At the “Balancing Europe’s Energy System: Challenges, Solutions, and Prospects” forum, leaders from Transmission System Operators (TSOs), Distribution System Operators (DSOs), regulatory bodies, and the world’s leading technology companies will discuss practical steps to overcome the flexibility gap and build the resilient energy system of the future.

Join the discussion that will define the future of European energy.
