What is involved in gaining approval for grid connection?
Connection to the electricity grid is not simple; the solution is complex, as illustrated below: A cogeneration unit is a generating unit connected within a distribution network and not having direct access to the transmission network. This means that you require approval from the DNSP to connect to the grid. Various physical and contractual arrangements must be in place before a generation scheme can be connected to a DNSP’s network. There are physical arrangements and operating protocols that need to be met by the DNSP to meet their obligation of safety and reliability of supply; for example, electrical infrastructure such as cables, overhead lines, switchgear, civil works and addressing systems fault levels. The generator may be directly connected to the DNSP’s network or indirectly connected via a privately owned network. It may export power into the DNSP’s network or just offset (reduce) part of a customer’s large on-site demand. In all of these cases, the generator operates in pa
