The dimmable heat pump
APIs through which grid operators can shed and shift load. Where the plant allows it, not across the board.
- One integration instead of one per device and operator
- Flexibility markets access for your end customers
- Regulation aware along the rules of each country
- Grid operator The request comes from the control room: reduce output when the grid needs it. It goes to an interface, not to a device.
- Interface A handover point with two directions: request out, feedback back. One integration for every device and every grid operator, over EEBUS from July 2027.
- Plant The heat pump steps down rather than being switched off. Reduction happens where the operating state allows it, and the operator keeps control.
- Market The end customer gains something from it: access to flexibility markets and grid operator tariffs, without an integration of their own.
What the platform offers the grid
Grid operators can shed and shift load through APIs. The plant has a say: reduction happens where the operating state allows it, not uniformly across the fleet.
What that means for you as a manufacturer
Regulatory requirements for controllable consumption devices apply to your equipment whether or not you are prepared for them. The alternative to a platform integration is your own connection per device and per grid operator.
There is a second side to it: your end customers gain access to flexibility markets and grid operator tariffs.
Who this does not concern
Controllable loads are electrical loads. A biomass or pellet boiler is not one, and this chapter does not apply to it. Everything else in the platform applies there unchanged, see Biomass and pellets.
Rules
The relevant rules are section 14a EnWG in Germany, the EAG in Austria and the requirements of the respective grid operators. HVACloud implements them technically. We do not offer a legal interpretation, that belongs with your type approval.
In Germany subsidy eligibility has hung on this since July 2026: the federal subsidy requires an interoperable interface under section 14a, in EEBUS format from July 2027. EEBUS is implemented in HVACloud, ahead of that deadline. What that means for manufacturers is under Staying eligible.
