Build a Next-Gen Flexible Tariff

See how we enabled E.ON to launch the market’s first truly smart tariff in record time.

01

Win the race
for flexibility

Flexibility is the next era of energy. Everyone is talking about it, but the market is still wide open. The first utility to master flexibility won't just lead, they will capture the most valuable customers before the competition wakes up.

02

Don’t cut margins, create value

Turn household assets into revenue streams

In a commodity market, the lowest price wins. But cutting prices kills margins. With Delta Green, you don't cut margins, you create value. Use flexibility trading profits to lower customer bills, creating a price advantage that no standard energy supplier can compete with.

03

Monetize the assets you don't own

Your customers have built a decentralized power plant for you. You just haven't turned it on yet. Trading residential flexibility is a completely new income source. Turn every battery in your network into a profit generator.

We spent months listening to customers to map their fears and misconceptions. The result is a product that doesn't just technically work, but emotionally resonates.

Flexibility as a Service

Leveraging our own live portfolio, we help you define flexible tariffs that work. From designing rewarding systems to understanding customer fears and biases, we use our direct operational experience to help you overcome objections and build a product that resonates with the market.

I enjoy watching the system react in ten-second intervals, switching assets on and off. I appreciate that I don't need to guarantee availability—I can disable the service at any time. That is a huge benefit for customers.
