Accumulating 8 months, the power loss rate of Northern Power Corporation (EVNNPC) is at 4.58%, decreased by 0.42% over the same period in 2020.

With a series of power-saving programs under on-going implementation, the results are achieved in the reduced power loss, continuously lower than the planned targets, from 9.23% in 2011 to 8% in 2015. In 2015, the country saved more than 2,900 billion kWh, accounting for 2.34% percentage of commercial electricity.

Power loss not only reduces the quality of power supply but also affects business outcome greatly. Therefore, the reduction of power loss has always been a top concern of Northern Power Corporation (EVN-NPC).

Thus, the rate of power loss has reduced over the years. In 1997, power loss of medium voltage grid of the whole company was 10.35%, was 4.24% in 2010 and decreased to 3.66% in the first 6 months of 2011. Calculating by the current electric prices, with 1% of power loss reduced, Bac Ninh Power Company saves VND 10.5 billion for the State.

Solar panels are usually mounted in series, to sum up their voltages, and the resulting power is sent to a large inverter, which transforms the DC voltage into AC. One big issue with this scheme is that if shade falls on one panel, or it gets dirty, the inverter lowers the current of all the other panels, and causing power losses through inefficiency.
