Frequently Asked Questions
Some customers do not want their generation systems, like solar panels, to export power to the electrical grid and wish to interconnect their system so they consume all energy generated on-site. However, these systems are still grid-connected and, as such, need rules in place to ensure they do not negatively impact the grid.
