(4) Updates on Application Process for Generating Facility

The Electrical and Mechanical Services Department (EMSD) established data link with the power companies for exchanging data in order to automate the registration process of generating facility (GF) as far as practicable.  After the meter installation and grid connection of the GF, relevant data such as the Feed-in Tariff (FiT) application number and commencement date of the FiT Scheme will be transferred from the power company to the EMSD automatically.  Hence, the GF registration applicant no longer needs to send a copy of the "completion letter" Note 3 to the EMSD.

Under the new GF registration application process, the GF registration applicant has to submit "Form GF1" together with the required document for the supporting structures of GF stipulated by the relevant government departments (such as below listed) to ensure compliance with the relevant structural safety requirements.  For the change of particulars regarding the registered GF, the applicant is to submit "Form GF2" together with the required document for the supporting structures of GF stipulated by the relevant government departments if relevant minor works or alteration and addition works to the supporting structures of GF have been carried out.

The above-mentioned process will be implemented on 14th June 2024.

Note 3: The applicant, who participated in FiT Scheme on or before 31st December 2023, shall submit a copy of the "completion letter" in order to complete the registration.
