Flex Appeal: Europe's Grid Is Worth €12 Billion

McKinsey projects Europe's demand-side flexibility market will reach €12B by 2030, as renewable growth strains grid balance

2 Apr 2026

Europe's electricity grid is undergoing a quiet transformation, one measured not in new power plants but in how, and when, consumers choose to use electricity. According to an analysis by McKinsey's Electric Power and Natural Gas practice, the continent's demand-side flexibility market is forecast to triple from €4 billion in 2024 to €12 billion by 2030, propelled by rapid renewable expansion and accelerating electrification of industry and transport.

The growth reflects a fundamental shift in grid management strategy. As wind and solar capacity scales up across the continent, grid operators face mounting pressure to balance supply and demand without building costly new infrastructure. Demand-side response, the practice of adjusting electricity use in response to grid signals or price incentives, is emerging as a faster and cheaper alternative, analysts said. McKinsey projects its share of Europe's total flexibility supply will roughly double, rising from approximately 10 percent in 2024 to 21 percent by 2030.

The commercial stakes are considerable. Of the projected €12 billion value pool, approximately €8 billion is expected to be accessible to commercial and industrial players through grid services and wholesale market arbitrage, according to the analysis. Europe will require as much as 75 percent more flexibility capacity by 2030 than it currently has. The European energy regulator ACER has cautioned that network costs could rise between 20 and 40 percent by decade's end without broader flexibility deployment, while ENTSO-E estimates that fully mobilizing the continent's flexibility potential could save up to €5 billion annually in generation costs.

The regulatory architecture is beginning to catch up. An EU-wide Network Code on Demand Response, expected to take effect by 2027, is designed to harmonize market access rules across member states, potentially reducing the fragmentation that has slowed cross-border participation by industrial consumers.

Yet the gap between projected value and realized deployment remains substantial. Whether European businesses move quickly enough to capture the commercial window, or whether regulatory delays and market complexity blunt the transition, will determine how much of the €12 billion materializes in practice.
