For electricity consumers

What does an LEG change on the bill? The discount applies only to the grid-usage energy rate and only to the LEG share of consumption; the provider's service fee is deducted from it.

Annual consumption kWh kWh per year, shown on your electricity bill Grid tariff (energy rate) Rp. Rp./kWh excl. VAT, the «grid usage» position

LEG discount 20% (several grid levels, e.g. municipality-wide LEG) 40% (same grid level, e.g. one transformer district)

LEG provider service fee Rp. Rp./kWh excl. VAT on LEG electricity; EKZ «Gemeinsamstrom» 2026: 1.50, self-organised LEG: 0 LEG share of consumption: 30 % Share of kilowatt-hours covered by simultaneous local production. Without storage or load shifting, 20 to 40% is realistic.

Practically cost-neutral: discount and service fee cancel out. Joining costs nothing, but saves nothing either.

For solar producers

Compares selling surplus into the LEG with the standard feed-in remuneration (reference market price with minimum remuneration and certificate revenue, capped by the accountability limit).

Surplus fed into the grid kWh kWh per year (production minus self-consumption) Winter half-year share: 25 % Share of surplus in quarters 1 and 4; typically 20 to 30% for PV

LEG remuneration, winter / LEG remuneration, summer / Rp. Rp./kWh excl. VAT; EKZ «Gemeinsamstrom» 2026 for systems up to 30 kWp: 11.97 / 9.00

Feed-in remuneration, winter / Feed-in remuneration, summer / Rp. Rp./kWh excl. VAT incl. certificates; EKZ 2026: winter approx. 10.96 (Q1 reference market price 10.27, capped), summer approx. 9.00 (minimum 6.00 plus 3.00 certificates)

Defaults: EKZ tariff collection 2026 and EKZ «Gemeinsamstrom», as of August 2026, without guarantee. Consumer amounts incl. 8.1% VAT, Rp. values excl. VAT. Other grid areas: enter the values from your own tariff sheet.

How the calculator works

Effect for consumers: LEG kilowatt-hours × (grid energy rate × discount − service fee). The discount applies only to the grid-usage energy rate and only to the share of consumption covered by simultaneous local production. Energy price, levies, metering and base fees remain unchanged. Franc amounts include 8.1% VAT.
Effect for producers: Surplus × (LEG remuneration − feed-in remuneration), split into winter and summer half-years. The feed-in defaults reflect effective EKZ 2026 values: reference market price or minimum remuneration, plus certificate revenue, capped by the accountability limit.
Where the defaults come from: From the EKZ tariff collection 2026 and the EKZ «Gemeinsamstrom» product (as of August 2026). Every value can be overridden, so the calculator works for any grid area whose tariff sheet you have.
