Electricity price consists of several parts:
Foremost the is a settlement for power supply distribution from the power plant to consumer (power parameters). This part is subjected to regulation and prices are set by Energy Regulation Office (ERO) for oncoming year usually during November. This part can include the fee for ecxeeding of agreed reactive power consumption. The fee for injection of reactive power into network needs to be payed too.
KWh rate set by retailers create another part of electricity price.
We can analyze above mentioned parts of overall energy price and determine the way how minimize these parts, if it is possible, through staff measures or technical improvements in point of consumption that minimizing the active and reactive power flows in point of connection.
