Our data sources

What it measures: the average price of electricity to residential customers, in cents per kWh, for each state and for the US as a whole. It comes from Table 5.6.A of the U.S. Energy Information Administration’s Electric Power Monthly.

How often: monthly, published with about a two-month lag.

How we use it: as the default price for US calculators, by state. Because it is an average, it spreads typical fees and taxes across each kWh. EIA data is in the public domain.

What it measures: household electricity prices for the consumption band of 2,500–4,999 kWh a year, including all taxes and levies, in national currency. The dataset code is nrg_pc_204 and it covers around 40 countries.

How often: twice a year, for January to June and for July to December.

How we use it: as the default price for European countries in the dataset. We reuse Eurostat data with attribution.

What it measures: the Direct Debit average unit rate and standing charge for electricity in Great Britain under the energy price cap.

How often: quarterly.

How we use it: the unit rate is the default price for UK calculators. We do not add the standing charge to single-appliance costs, because you pay it whether or not the appliance is on. Actual rates vary by region, so check your own bill for the rate that applies to you.

What it measures: modelled residential prices in each province and territory for a household using 1,000 kWh a month on the cheapest available rate plan, including delivery charges and excluding sales taxes. It comes from the Canada Energy Regulator's market snapshot on what households across Canada pay for electricity.

How often: we check it every year, when the regulator publishes a new snapshot.

How we use it: each province's figure is shown on the Canada page. The national figure is our own population-weighted average of the provinces and territories, using Statistics Canada population estimates. Sales taxes are not included, and the page says so.

What it measures: the regulated default offers that cap standing-offer prices: the Australian Energy Regulator's Default Market Offer for New South Wales, south-east Queensland and South Australia, and the Essential Services Commission's Victorian Default Offer. Each gives a yearly bill, GST included, for a flat-rate household at an assumed yearly use.

How often: once a year, from 1 July.

How we use it: we divide each yearly bill by its assumed use to get an all-in price per kWh that includes the daily supply charge. The national figure is the simple average of four regions. Western Australia uses the government-set Synergy A1 tariff.

What it measures: the slab rates for residential customers of the state-owned distribution companies and K-Electric, set by the federal government on the regulator NEPRA's advice.

How often: whenever the government notifies a new tariff, usually once a year, plus monthly and quarterly adjustments that we do not include.

How we use it: the price shown is the rate of the slab a household using about 250 units a month reaches. It excludes sales tax, fuel and quarterly adjustments, surcharges and fixed charges, so your bill's real price per unit is higher. The full slab table is on the Pakistan page. Rupee comparisons in US dollars use the State Bank of Pakistan rate.

What it measures: the euro reference exchange rates published by the European Central Bank.

How we use it: only for the approximate “≈ USD” column that helps you compare countries. It never changes a result shown in your own currency. For currencies the ECB does not publish, such as the Pakistani rupee, we use the national central bank's rate.

For countries not covered above, we do not guess. You enter the price per kWh from your electricity bill. If your country uses slab or tiered tariffs, our bill analyzer can help you find the rate for the slab you are in. We add more countries as we check each regulator's published tariff.

An automated job checks every week for new data. New data is validated before it is published. If it is malformed, the build fails and the site keeps the last verified data. We would rather show an older correct price than a new wrong one.

Prices we copy from a regulator by hand carry the date we last checked them and a date by which we check again. The weekly job warns us when that date has passed.

For countries without an automatic feed, we copy the household tariff or official average from the national regulator or a regulated utility, and cite it with a link, the date it took effect and the date we last checked it. The table below lists every one, and each country's page explains exactly what its figure includes and leaves out.
