According to NEPRA’s regulation for net-metering, mandatory safety requirements for the interconnection facility are to be fulfilled by the applicant before submitting the application. In the absence of such requirements, the DISCO will call the technical feasibility of the distributed generation facility for review.
Anti-islanding is a built-in feature in an inverter, which trips the flow of energy to the grid on grid failure. Installing an anti-islanding enabled inverter is mandatory as per the net-metering regulations
The applicant has to install an interconnection disconnect switch rated for its voltage and fault current requirements, which will cut the flow of energy back to the grid if required. That disconnect switch shall be locked and be accessible to both the applicant and the DISCO personnel, and shall meet applicable IEC and IEEE standards.
