Effects of residential customers´ energy efficiency on electricity distribution business

Energy efficiency has been a topic of discussion for a long time, and now it seems to have effects on energy consumption. Energy efficiency actions will influence on customers´ electricity usage. This can also be seen in the amount of transmitted electrical energy and power through distribution network. Total effects of energy efficiency on transmitted electrical energy and power are not known. Changes in transmitted energy through network will also have effects on distribution system operator´s (DSO) business. This paper presents methodology for estimating effects of energy efficiency on electricity distribution. It is concluded that energy efficiency will have effects on transmitted electrical energy and power. Regionally those effects may differ. Finally, changes will happen also in electricity distribution business.
