A power producer,
in this case a hydropower plant, feeds the energy it produces to the “mains
supply” (electricity grid) from which the customer draws its power. The energy
flow is shown in the picture as a lightning bolt.
At the same time numerous
other power plants are also loading the mains supply with electricity, also
drawn on by consumers.
It is therefore physically impossible to distinguish between Green Power
and conventional electricity. The mains supply itself is better compared
to a lake consisting of a mix of various types of electricity.
Crucial to the supply of Green Power is of course, the financial and contractual
agreement at hand, which is presented in the picture using the $-sign. The
customer comes to an agreement with the electricity supplier, signs a contract,
and pays the arranged price for its electricity usage. The electricity company
then promises in return that the amount of Green Electricity required by
the customer will be ordered and supplied by the agreed upon producer.
As a result, the customer can then assume that
a) the electricity it uses was produced and fed into the mains supply
by green power sources
b) his money is distributed
to those chosen power plants, not forgetting the fees for the electricity
supplier and mains operator involved.
