Struct SettlePosition 

pub struct SettlePosition {
    pub description: String,
    pub legal_basis: String,
    pub kwh: Decimal,
    pub rate_ct_kwh: Decimal,
    pub eur: Decimal,
}

A single billing component of a settlement calculation.

Each position represents one regulatory charge line: net_eur = kwh × rate_ct_kwh / 100.

Convert to a billing::LineItem for invoice generation via .to_line_item().

Fields

description: String

Human-readable description of this charge line.

legal_basis: String

Legal basis for audit trail (e.g. "§21 EEG 2023", "§23a EEG 2023 i.V.m. Anlage 1").

kwh: Decimal

Energy quantity this position applies to (kWh).

rate_ct_kwh: Decimal

Rate in ct/kWh. May be negative (e.g. PostEegSpot at negative EPEX).

eur: Decimal

Net amount in EUR (kwh × rate_ct_kwh / 100, rounded to 5dp).

Positive = NB owes Anlagenbetreiber (typical). Negative = Anlagenbetreiber owes NB (post-EEG at negative EPEX).

Implementations

impl SettlePosition

pub fn to_line_item(&self) -> LineItem

Convert this position to a billing::LineItem for use in billing::BillingDocument generation (invoice, settlement receipt).

Uses billing::LineItem::for_usage() with the signed rate — negative EPEX prices produce a negative net_amount on a Sign::Debit item, correctly modelling the post-EEG scenario where the plant owes the NB.
