# Delta Green

> Delta Green is an energy-tech company operating a flexibility-aggregation platform. It connects household energy devices (solar panels, batteries, EVs, heat pumps) to energy markets — delivered as a white-label service for electricity suppliers (B2B).

Delta Green lets electricity suppliers monetise the flexibility of their residential customers on energy markets under their own brand, earning the supplier €20–100 per household per month depending on the market. The solution combines a software platform with the Delta Link hardware gateway, requiring no upfront infrastructure investment from the supplier.

The solution is deployed and live across 5 European markets, with leading electricity suppliers including E.ON. Delta Green is ancillary-services-ready: it was the first in Central Europe to enrol hundreds of households into aFRR (automatic Frequency Restoration Reserve) for TSO balancing, giving utilities a future-proofed flexibility solution rather than a tariff-only product. The end customer installs Delta Link themselves in about 3 minutes — it is coin-sized and ships by post. The company is backed by three VC funds, including Credo Ventures.
