Live at gridXdays 2025 – panel 4: Energy flexibility: Tomorrow’s powerful currency

Live from gridXdays, this panel explores energy flexibility as the new currency of the power system, from dunkelflaute and long-duration storage to residential flex, regulation and smart tariffs that align grid stability with lower costs for end users.

What you’ll get from this episode

Why energy flexibility is the new currency

The panel breaks down why energy flexibility is becoming the new energy currency. They explain how a mix of long-duration storage, interconnectors and flexible demand can handle extreme events like dunkelflaute while everyday flexibility shifts consumption into sunny or windy hours instead of routinely wasting highly valuable zero-marginal-cost renewables.

Unlocking small-scale flex with smart meters

Small-scale flexibility takes center stage as the speakers discuss orchestrating millions of rooftop PV systems, residential batteries, EVs and heat pumps. They highlight why smart meter rollout and home energy management are essential to aggregate these assets into meaningful flex pools that support both wholesale markets and local grid constraints.

Forecasting, data and price signals that work

Forecasting and data transparency emerge as recurring themes. The panel explains how better weather modeling, real-time operational data and coordinated price signals from TSOs, DSOs and retailers enable smarter trading strategies, reduce curtailment and underpin simple product designs like flat EV subscriptions or dynamic tariffs that customers can actually understand.

Regulation, business models and the last ten percent

Finally, the experts unpack upcoming EU market design reforms, German grid tariff changes and capacity market design debates. They outline how bidirectional charging, battery arbitrage and new incentive schemes for grid operators can unlock energy flexibility at scale while keeping participation easy, fair and financially attractive for households and businesses.

Key quotes: Pushing flexibility into action

“Energy flexibility is not one silver bullet – it is a series of solutions that together turn variability into real system value.”

“Consumers do not care about kilowatt hours or market signals – they care about comfort and a fair bill, so flexibility has to feel effortless.”

“Without smart meters and good data, there is no meaningful energy flexibility – digital infrastructure is the entry ticket to the future energy system.”
