Technical Guidelines on Grid Connection of Renewable Energy Power Systems

To assist the public to better understand the technical issues relating to grid connection of Renewable Energy (RE) installations, the Electrical and Mechanical Services Department has compiled a “Technical Guidelines on Grid Connection of Renewable Energy Power Systems” (hereinafter referred to as “Technical Guidelines”). The Technical Guidelines addresses the aspects of safety considerations, system protection, power reliability, major devices and their functions, testing and maintenance for grid-connected RE power generation systems.

In view of the implementation of the revision of the Code of Practice for the Electricity (Wiring) Regulations in December 2020, the Technical Guidelines was revised in 2021 to incorporate the updates.
