Hvad er en kWh? kWh er en måleenhed, der bruges til at tage højde for elforbruget over en periode. kWh måler energiforbruget i kilowatttimer.. 1 watt svarer til at forbruge 1 joule i 1 sekund. Derfor repræsenterer 1 kW forbruget af 1.000 Joule i 1 sekund. For eksempel vil en enhed, der bruger 1 kW og er tændt i 1 time, forbruge i alt 3.600.000 Joule.
Based on an EnergySage analysis of a Department of Energy database, a typical heat pump in a typical home uses 5,475 kilowatt hours (kWh) per year —easily the single biggest energy-user in most houses. That''s enough electricity to run nine full-size fridges year round, or power a Tesla Model 3 for 15,000 miles.

the plant. It is calculated at a flat rate of 20 paise per kWh of the total energy scheduled (in excess of the design energy 5) plus 75% of the energy consumed in pumping from the lower reservoir to the upper reservoir. The major drawback of the current pricing mechanism is that it does not take into account the grid flexibility aspects of PHES.
