What to do with the price of electricity
Three calculators that turn the day-ahead market's quotes into figures you can use. All of them work without JavaScript and can be bookmarked with their result.
When electricity is cheapest
The continuous window of time in which an appliance costs least, from the published quotes.
Charging an electric car
How long it takes, how much it draws from the grid and when it is worth plugging in.
The heat pump, at market price
The annual electricity use and the energy component, compared with another heating system.
Solar calculator
Panels, panels with a battery, or just a battery if you already have panels. The calculator uses the solar radiation where you live, your household's consumption and local energy prices to estimate the cost, the yearly saving and the payback period.
Every figure is at the wholesale price. Cost computed at the wholesale day-ahead price. It excludes the network tariff, levies, excise duty, VAT and the supplier's margin — which together are usually larger than the energy component.
