To reduce your bill in Geneva, start with the tariff for your address and your consumption. Compare settings, renovation and solar using a full budget rather than assuming one price or payback period applies across the canton.
Identify the tariff for your address Find the DSO, product, year, billing period and meter on your bill. Check the schedule for your municipality and consumption profile. A cantonal average cannot replace your contract; households in a canton do not necessarily share a supplier or tariff.
Compare matching periods Match readings, estimates, kWh, advance payments and adjustments. Separate energy, network, metering, levies and VAT. A higher total may reflect consumption or a different period. Check actual charges before attributing the difference to a general price rise.
Choose measurable savings Identify heating, hot water, charging and unnecessary appliance use. Compare timing, cost, comfort and safety before changing settings. Night electricity is not always cheaper; use your contract’s time bands and prices. Assess control adjustments before buying equipment.
Calculate solar for your home Request monthly generation and consumption during the same hours. Distinguish electricity used on site from sold surplus. Include installed cost, maintenance, finance and replacement. Solar does not freeze every household cost for decades. Compare a battery with a version without storage under the same assumptions.
Confirm grants and payback Have Pronovo support calculated and local programmes checked for the specific project. Confirm conditions, combined support and application timing before ordering. Payback must follow from the quote and actual tariffs under conservative and favourable scenarios. Savings after payback are not all net profit when costs remain.
A scenario to examine in Geneva: a condominium with shared heating Consider a building where several owners are planning a renovation together. This example describes a decision to prepare, rather than a feature of every Geneva home. Before comparing equipment, identify who can commission the work and how investment, charges and benefits will be allocated.
Clarify the meter’s scope: shared areas, communal heating or apartments. A saving calculated for the entire building does not automatically produce the same reduction in each private bill. Request a diagram of energy flows and an allocation method the owners’ meeting can understand.
Then examine service continuity. Which shared equipment must operate during an interruption? Who monitors alerts and authorises an intervention? Include responsibilities in the offer and check compatibility with existing contracts.
For the vote, present alternatives with full costs and effects on each co-owner. Include necessary permissions, timing and maintenance conditions. Assess collective financing on its own terms rather than applying a detached-home calculation directly.
