Conservation voltage reduction and voltage optimisation on Irish distribution networks

Conservation Voltage Reduction, reducing the supply voltage by a small percentage such that customer equipment and distribution transformers may operate more efficiently, has been shown in the US to be very beneficial in delivering Energy Savings. ESB Networks, is trialling the effect of this on Irish Networks with positive results emerging from early stages trials. This paper looks at the actual results of the triled and considers these results in the context of expected results through modelling and simulation and comparison to international results.
