§14a EnWG module for steuerbare Verbrauchseinrichtungen (controllable loads).

Source: BNetzA BK8-22/010-A, „Festlegung von Netzentgelten für steuerbare Anschlüsse und Verbrauchseinrichtungen (NSAVER) nach § 14a EnWG“ (Beschluss 23.11.2023). Modul 1 and Modul 2 apply ab 01.01.2024 (Tenor 1. d) and 2. c)); Modul 3 is billed ab 01.04.2025 (Tenor 3. d)).

BK6-22-300 is the companion Festlegung — it governs the netzorientierte Steuerung a Betreiber must take part in, not the Netzentgelt modules.

All three modules are mandatory for eligible controllable loads (heat pumps, EV chargers, battery storage ≥ 4.2 kW) registered with the NB. The LF/NB must offer at least Modul 1 to all eligible customers.

Variants

Modul1

Modul 1 — pauschale Reduzierung des Netzentgelts.

A flat reduction applied for the whole billing period, published by the NB either as an annual EUR amount or as a factor on the rate. It needs no additional metering, which is why it is the default where the connection holder makes no choice. It is the one base module Modul 3 may be added to.

Modul2

Modul 2 — prozentuale Reduzierung des Arbeitspreises.

The Arbeitspreis of the Netzentgelt is reduced by a percentage for the controllable device, which therefore needs its own metering — the reduction attaches to that device’s energy, not to the whole connection.

An alternative to Modul 1, not an addition to it, and it takes no Modul 3 (see Sect14aModule::combinable_with).

Modul3

Modul 3 — zeitvariable Netzentgelte, available from 01.04.2025.

Three Tarifstufen — Hochtarif, Standardtarif and Niedertarif — whose windows the NB publishes in the UTILTS Zählzeitdefinition. Requires an intelligent metering system. It may be combined with Modul 1 but not with Modul 2.

Implementations

impl Sect14aModule

pub fn bnentza_reference(self) -> &'static str

Canonical BNetzA decision reference for this module.

pub fn combinable_with(self, other: Self) -> bool

Whether two different modules may be held at once.

BK8-22/010-A offers one base module and one optional addition. Modul 1 and Modul 2 are the two forms the base takes — a pauschale reduction needing no metering, or a percentage on the device’s own Arbeitspreis — and the Anschlussnutzer picks one. Modul 3 re-prices the Arbeitspreis over time, so it composes with the pauschale Modul 1 and not with Modul 2, which would reduce the same Arbeitspreis twice.

Modul 1 + Modul 3 is therefore the only pair, in either order. A module paired with itself is not a combination and answers false.

pub fn label(self) -> &'static str

Display label for the module.
