Hybrid Greentech has begun trading Emaldo's residential batteries alongside its utility-scale fleet, clearing a barrier that has long kept individual home batteries out of Nordic wholesale and balancing markets. Those markets set a minimum bid size of 1 MW per hour, far beyond what any single battery can offer alone. Now, by folding Emaldo's fleet into Hybrid Greentech's existing retailer portfolios, batteries in individual Danish homes can bid into the same markets as its utility-scale assets, without any change to the customer's retailer relationship, billing or the hardware itself.

Previously, Emaldo One Home batteries ran on fixed local rules. Under the partnership, each unit installed in a Hybrid Greentech-balanced household now trades automatically, both intraday and into ancillary service markets, as part of a larger, actively managed portfolio. Hybrid Greentech, which acts as the sole balance responsible party for the retailers it works with, buys power when prices are low and sells when they rise, rather than merely following the day-ahead spot price.
Building on an existing platform
The aggregation runs on the same automated trading engine Hybrid Greentech already uses for its utility-scale battery assets, spanning more than 80,000 EV chargers, the largest cross-operator EV platform in Denmark, as well as several thousand residential heat pumps. “We don't just optimise a battery, we trade the home it sits in,” said Rasmus Rode Mosbæk, Hybrid Greentech's chief executive. "Our batteries are engineered to perform," said Alasdair Firth, Emaldo's chief product officer. "Partnering with Hybrid Greentech means that performance now shows up in the market itself, not just on a household dashboard." The deal currently covers Emaldo's residential batteries only, though both companies say it could extend to Emaldo's commercial and industrial product line in future.
Opinion: Battery storage is becoming growth infrastructure
In the Nordic countries, where flexible assets, batteries, EV chargers and heat pumps, are increasingly pooled to meet the scale thresholds required by wholesale and balancing markets. Emaldo already pays customers around €1 million a month through a separate grid-balancing scheme covering more than 150 MW of controllable capacity, underlining how much of that flexibility is now being aggregated and monetised through platforms such as that offered by Hybrid Greentech.
