This process helps IDNOs to ensure that the system has sufficient capacity and can continue to operate in a safe and reliable manner. It can provide assurance to third parties that all appropriate checks have been carried out and, in some instances, may be a requirement of household insurance cover.
The connection process has been developed by the Energy Networks Association (ENA), the main industry body that represents DNOs and IDNOs including GTC.
The ENA website also includes guidance for installers on assessing the capacity of existing services to buildings. Most domestic services provided by GTC are 100A single phase (230V), but some 80A or 60A services may exist. Older services from other DNOs may be rated less than this.
