How it works
Does it affect your comfort or your equipment? No. Activations are short — typically seconds to minutes — and designed not to affect your comfort or your equipment. Your home delivers frequency reserves in the background while everything works as normal.
NM1 works in three steps: you connect your device, we sell its flexibility as FCR-D to Energinet, and your share of the earnings is paid out to you.
1. Connect
You connect your home with the product that fits your setup. The device needs stable wifi, typically 2.4 GHz:
- Plug for electric radiators and fan heaters you don't use — plug it in and sign up with NM1, done.
- HeatSync for Metro Therm hot water tanks — fitted by a licensed electrician.
- Balance for larger installations from 10 kW.
If you already own a Shelly or a home battery with a supported inverter (incl. Solplanet), we connect it through the integrations.
See the full line-up on the products page.
2. We optimise and bid
Energinet — the operator of the Danish power grid — buys frequency reserves in daily auctions: one auction for each of the day's 24 hours. NM1 aggregates your and other households' devices into one virtual power plant and bids the combined flexibility as FCR-D.
If the bid wins, your device stands ready in those hours. It is only activated when the grid frequency deviates — briefly and fully automatically.
| Hour | Bid capacity | Status |
|---|---|---|
| 00:00–01:00 | Full | Standby |
| 06:00–07:00 | Full | Standby |
| 07:00–08:00 | Full | Activated |
| 12:00–13:00 | Partial | Standby |
| 18:00–19:00 | Full | Activated |
| 23:00–24:00 | Full | Standby |
And so it continues around the clock — 24 auctions in total. Most hours your device simply stands by; an activation lasts seconds to minutes.
