Electricity meter data for one billing period.

Fields

arbeitsmenge_kwh: Decimal

Total energy in kWh (Arbeitsmenge).

arbeitsmenge_ht_kwh: Option<Decimal>

High-tariff energy in kWh (HT, for Zweitarif). None = single tariff.

arbeitsmenge_nt_kwh: Option<Decimal>

Low-tariff energy in kWh (NT, for Zweitarif). None = single tariff.

spitzenleistung_kw: Option<Decimal>

Peak demand in kW (Spitzenleistung, § 12 StromNZV).

steuerung_stunden: Option<Decimal>

§14a EnWG: hours the controllable device was under NB management.

zaehlernummer: Option<String>

Zählernummer (§41 EnWG — mandatory on electricity invoices).

When set, appears as an informational position on the invoice. Overrides BillingContext::zaehler_id for this specific meter.

zaehlerstand_von: Option<Decimal>

Zählerstand at the start of the billing period.

§41 EnWG: billing invoices must show the meter reading at period start.

zaehlerstand_bis: Option<Decimal>

Zählerstand at the end of the billing period.

§41 EnWG: billing invoices must show the meter reading at period end.

metering_mode: MeteringMode

Metering mode — SLP, RLM, or iMSys (Smart Meter).

Used to validate tariff compatibility (§41a requires Imsys) and to label estimated readings correctly on the invoice.

ablesungsart: Ablesungsart

§ 40 Abs. 2 Nr. 6 EnWG — how the reading was obtained.

See also MeterInput::billable_kwh, which is what decides whether there is any consumption to price.

Stated on the invoice beside the readings themselves. Rechnerisch implies Self::is_estimated; the two are kept separate because a caller that knows only “this is an estimate” can still say so.

is_estimated: bool

true when the consumption figure is an estimate rather than a reading — either a § 40a Abs. 2 EnWG Verbrauchsschätzung or an Ersatzwert the Messstellenbetreiber formed and passed on under § 40a Abs. 1 Satz 1 Nr. 1 EnWG.

§ 40a Abs. 2 Satz 3 EnWG has the invoice state the estimate, the ground that makes it admissible and the factors behind it „unter ausdrücklichem und optisch besonders hervorgehobenem Hinweis“.

zaehler_replaced: bool

true when the meter was replaced during this billing period (Zählerwechsel).

When set, zaehlerstand_von / zaehlerstand_bis may relate to different meter serial numbers. The invoice must note the meter exchange.

coverage_pct: Option<Decimal>

Share of the billing period covered by billable readings, 0–100.

A sum over the readings that did arrive says nothing about the ones that did not: a month delivered up to the 3rd sums to a plausible Arbeitsmenge and bills as a complete month. Below 100 the invoice rests in part on a § 40a Abs. 2 EnWG Verbrauchsschätzung, which the document has to say so prominently — the MENGE_UNVOLLSTAENDIG finding carries that.

None when the source states no coverage.

Implementations

impl MeterInput

pub fn billable_kwh(&self) -> Decimal

The consumption there is to price, in kWh.

arbeitsmenge_kwh where it is stated, otherwise the HT/NT registers. A Zweitarif caller may legitimately supply only the split — the total is its sum, not an independent fact — and gating the whole Arbeitspreis block on the total alone billed such a customer nothing for their electricity while still charging them the Stromsteuer.

Trait Implementations

impl Clone for MeterInput

fn clone(&self) -> MeterInput

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MeterInput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MeterInput

fn default() -> MeterInput

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MeterInput

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for MeterInput

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
