Energy billing
Energy bills are the basis for calculating energy flows in money. Purchases / consumption are recorded in kilowatt hours (kWh), e.g. B. for electricity and heat ( heating billing ); Volume in m³, e.g. B. for natural gas; Volume in liters, e.g. B. heating oil and liquid gas, which is also recorded in kg. There is a standard consumption price for all units; provision, delivery, measurement and peak loads are also charged. Energy tariffs are checked by the Federal Network Agency , and complaints can also be submitted there.
The individual factors are listed on the regular energy cost bills. The reactive work can be added to the electricity price for a fee. The electricity and natural gas prices include transmission costs and concession fees.
In the energy bills you can see which amount was consumed in a billing period and what the maximum consumption was.
In the case of load profile-measured customers, the peak load is calculated as the maximum provision.
For consumers who produce their own electricity ( photovoltaics , CHP , hydropower , ORC or others), the energy cost billing also records how much power is generated and the surplus that has been fed into the power grid. This is where credits are created, offset or paid out.
Load profile billed consumers can request a load profile report from their supplier. You will receive a column of numbers containing the measured values in 15-minute intervals.
By evaluating these columns of figures, the consumer can see at what point in time his purchase was highest. This is the point in time at which the highest costs arise, since the provision costs are determined from this point in time of the highest reference point until the end of the specified calculation period.
By evaluating the load profile log and reducing this power peak, the consumer can save a considerable proportion of his energy costs.
