What does Grid Saturation Mean?
Grid Saturation is a measurement/ study that is done by HECO in which they study/ determine the amount of electrical load created by alternative energy that goes back to grid. This can be reviewed by the Location Value Map that HECO present on the website. The map will show what areas are tied up and which areas are ok to install. The area that usually approved quickly are 25%-75% grid saturated this also means that they do not need any study or upgrades. The grid saturated areas that are 75%-100% means that the grid maybe full and that you may be charged an upgrade fee to interconnect.
