Swiss Electricity Tariffs (ElCom)

Official Swiss electricity prices per municipality and grid operator, from the federal regulator ElCom, 2011 to 2027. You get the total price and its components in Rappen per kWh, per consumption category (H1-H8 households, C1-C7 businesses). USD 0.002 per tariff row (USD 2 per 1,000). One clean row per tariff, instead of a SPARQL query.

Year	Municipality	Grid operator	Category	Total Rp./kWh	Energy	Grid usage
2027	Zürich	Elektrizitätswerk der Stadt Zürich	H4	24.632	7.884	11.122
2027	Zürich	Elektrizitätswerk der Stadt Zürich	C3	24.432	8.787	11.985
2027	Bern	Energie Wasser Bern	H4	31.113	10.75	13.45
2027	Bern	Energie Wasser Bern	C3	29.39	10.75	14.1

The rows come from a real cloud run of 04.11.2026 (2 municipalities, 2 categories). The full item is under Output.

Who uses it

• Energy advisers, solar and heat-pump installers: the local tariff for the payback calculation of an offer.
• Proptech and real-estate portals: the electricity cost of a home per municipality, with H4 as the benchmark.
• Price comparisons and research: all ~2,100 municipalities of a year, or the trend since 2011.

What it does not do

• Prices exclude VAT. The total has no fixed costs (they are separate fields).
• Next year's tariffs appear each September, when ElCom publishes them.
• The operator's own tariff sheet (tariffSheetUrl) is authoritative for a bill.

Input

{ "years": ["2027"], "municipalities": ["261", "Bern"], "categories": ["H4", "C3"], "product": "standard" }

Field	Meaning
years	Four-digit years, 2011 or later (the data starts in 2011). Empty = the latest year in the data.
municipalities	BFS municipality numbers (261 = Zurich) or official names (exact, case-insensitive). Empty = all ~2,100. An unknown name fails the run; a number without tariffs gives a warning.
categories	H1-H8, C1-C7. Empty = all fifteen. H4 is the usual benchmark.
product	standard (the operator's default product, ~2,270 municipalities a year) or cheapest (its cheapest product, ~770 municipalities).

Categories (annual consumption, as ElCom defines them): H1 1,600 kWh 2-room flat; H2 2,500 kWh 4-room flat; H3 4,500 kWh 4-room flat with electric boiler; H4 4,500 kWh 5-room flat, electric cooker and dryer, no electric boiler; H5 7,500 kWh 5-room house with boiler; H6 25,000 kWh house with electric resistance heating; H7 13,000 kWh house with a 5 kW heat pump; H8 7,500 kWh large, highly electrified flat; C1 8,000 kWh to C7 7,500,000 kWh businesses (C1-C4 low voltage, C5-C7 medium voltage with their own transformer station).

}

Prices are Rappen per kWh, excl. VAT. totalRpPerKwh is ElCom's total of all variable costs (energy + grid usage + levies + federal surcharge + metering); fixed costs are not in it. Values are passed through as published: a few rows (43 of 30,811 in 2027) have no total, and the field is then null. Where the source itself states two different values for one tariff (it happens in a handful of older observations - e.g. municipality 295, operator 589, 2020, where the total reads both 16.077 and 14.727 Rp./kWh), the smaller value of each such field is given, and conflictingFields lists the fields concerned (empty for all of 2027); the run logs a warning with the number of such rows. Treat a row with a conflict as unreliable and check ElCom's own viewer.

Pricing (pay per event)

Event	Price	When

A whole year for all of Switzerland, standard product (about 30,800 rows in 2027) costs about USD 62; one municipality's benchmark a fraction of a cent. A run that finds nothing is free. You can set a maximum charge for a run.

Data source and terms

• Source: ElCom's open-data cube "Electricity tariff per provider" (https://energy.ld.admin.ch/elcom/electricityprice) on LINDAS, the Confederation's linked-data service, read through its public SPARQL endpoint (https://lindas.admin.ch/query, no key). ElCom's own viewer is https://www.strompreis.elcom.admin.ch/.
• Terms: the cube's metadata on LINDAS states its licence as "Open use" (opendata.swiss terms of use NonCommercialAllowed-CommercialAllowed-ReferenceNotRequired: commercial use allowed, no attribution required). Each item names its source anyway. ElCom's tariffs are facts published by a federal authority.
• The tariffs are the operators' reports to ElCom; the operator's own tariff sheet (tariffSheetUrl) is authoritative for a bill.

Run summary

The run summary is in the default key-value store under SUMMARY. The data comes as the source publishes it, without warranty.
