PCP
A kilowatt-hour measures quantity
Consumption is expressed in kilowatt-hours. A variable tariff is the price charged for each unit. Higher consumption can therefore offset a tariff reduction. Comparison starts by checking both figures and the billing period.
More time in the home or a new use can change quantity. An estimated bill uses different information from a statement based on a reading. Attributing a change requires checking the period and calculation method rather than comparing payment totals alone.
Different charges pay for different functions
The energy component concerns supply. Network use finances delivery through available and maintained infrastructure. Metering is identified separately in tariffs. Other levies have particular public bases and purposes.
Those components can move in different directions. Regrouping invoice lines can also change presentation without removing a cost. If metering has been separated, network and metering need to be compared together. Adding only lines retaining the same name can mislead.
Published tariffs belong to a particular operator and product. A “Swiss electricity price” does not mean one uniform amount applies everywhere. National averages and medians describe a distribution; they do not replace the local tariff sheet.
Fixed charges affect small users differently
Consider a purely illustrative calculation: CHF100 in annual fixed charges and an overall variable tariff of 25 centimes per kilowatt-hour give CHF600 for 2,000 kWh within the assumed scope. This is neither a real offer nor an official model bill. It demonstrates two mechanisms.
If consumption falls by 10%, the variable amount drops from CHF500 to CHF450 and the total to CHF550. The bill therefore does not fall by 10%, because the fixed charge remains. Taxes, VAT and any components outside the assumption would need to be added according to the actual invoice.
For the PCP, the fixed-variable split is also a social question. A high fixed charge can fall proportionally harder on small users. Saving incentives need assessment alongside unavoidable needs and the household’s ability to change equipment.
Compare the same profile and tariff year
ElCom uses, among other categories, the H4 profile of 4,500 kWh annually. It enables standardised comparison, not a prediction for every home. A different quantity, operator or tariff structure produces another result.
A useful comparison identifies the tariff year, supply area, product and fixed components. It also checks what the displayed amount includes. Every percentage needs its base: energy alone, the network or the total bill.
From the invoice to public scrutiny
ElCom does not approve every tariff in advance. It supervises and can examine costs within its powers. That distinction matters when citing the regulator is offered as a sufficient answer to a question.
The PCP supports invoices that make the tariff sheet and reasons for changes accessible. Controlling costs requires distinguishing procurement, network investment and public levies. Otherwise the debate can ask consumers alone to save enough to offset decisions over which they have no direct influence.
