The time to invest in residential flexibility is now

Rising DER adoption is reshaping demand. Partnering with Synergi helps you cut costs, reduce risk, and scale flexibility 5x more efficiently.

Tap into unused flexibility

80 GW of demand-side flexibility from residential and small C&I assets remains unutilised across Europe — representing a potential market of €58 billion per year.

The flexibility exists. It simply isn't orchestrated. Yet.

Building in-house is expensive and slow

Launching flexibility programs from scratch demands significant time, deep DER expertise, and capital.

Synergi is the only scalable way to unlock hundreds of MW across a fragmented asset base — so you can go live in weeks, not years.

Avoid costly over-investment in new capacity

Europe faces a projected 60 GW peak shortfall by 2030. Without orchestration, utilities risk overspending on new infrastructure. With Synergi, you can activate existing customer assets instead — at a fraction of the cost.

Partnering with Synergi is 5x more cost-efficient.

Proven end-user adoption at scale

Household flexibility starts with engagement — and no one does it better.

More than 15,000 households across 15+ European countries are already on the Synergi platform.

With multiple years of real-world user acquisition testing, 80,000+ data points, and a proven playbook that delivers 135% improvement in pilot conversion, we turn enrolled households into reliable megawatts.
