Overview
- Since early 2025, new heat-pump installations fall under §14a EnWG and must use a smart meter that allows temporary throttling during grid bottlenecks.
- Owners receive network-charge relief tied to this setup, with discounts of up to 60% or a flat rebate of up to €190 a year, and the entitlement applies even before installation is completed.
- The local grundzuständige Messstellenbetreiber is responsible for fitting the device, though customers may switch to a competitive operator if the rollout stalls.
- No upfront charge applies when the meter is installed under the legal mandate, while voluntary installations typically cost about €100 after courts curbed excessive one-off fees.
- Annual costs are capped at up to €50 for meter operation plus up to €50 for the required control unit, and suppliers must offer dynamic tariffs, though studies report limited household savings without added services.
