In 2014 then revised in 2019 the European Commission published regulations on the minimum specifications of new Eco Power Transformers. These regulations also required that transformers not meeting these requirements could no longer be installed or sold except under defined exceptions. Typically, almost all networks above 11kV operate with a parallel plant; especially when it comes to transformers. Using models of some transmission/distribution sites and by inputting twelve months of half-hour transformer loading data into these models; the amount of unnecessary losses, due to their parallel orientation, should be quantifiable. Since these sites need to be capable of supporting a varying load profile, they are for considerable periods of time oversized. Using the model, a sequence of taking offline excess plant will definable not only reducing network losses (a reduction in transformer losses of 35% per site is feasibly achieved in the model) but also marginally improve the sustainability of some of these existing sites.
