Average Time between Completion of Solar Photovoltaic Systems Installations and Grid Connection, and Measures to Accelerate Process

Ms Valerie Lee asked the Minister for Trade and Industry (Energy and Industry) (a) over the past two years, what has been the average time between the technical completion of solar photovoltaic systems and their grid connection, for residential and industrial installations respectively; and (b) what measures are being taken to shorten this interval so that generated renewable electricity can be exported to the grid promptly.

We do not have data on the lag time between the completion of solar installations and their grid connection, as solar installers are not required to report the actual date of completion of solar installations to the Government or to SP Group.

For embedded solar photovoltaic (PV) installations with capacity below one megawatt alternating current (MWac), once the installation has been completed, tested and certified by a Licensed Electrical Worker (LEW), the LEW should promptly notify SP Group. If all technical requirements have been met and the required information is submitted, SP Group can inspect and turn on the installation within 10 calendar days of receiving a complete application.

For larger-scale solar PV installations with capacity of one MWac and above, and solar installations that are connected to the High Tension network, once the installation is completed, the LEW must submit a turn-on application to SP Group indicating preferred appointment dates that are at least four business days away. The inspection and turn-on are conducted during the appointment. Thereafter, the LEW must also submit a completed declaration to SP Group within seven business days. Compared to small installations, additional technical and regulatory requirements apply, and an SP PowerGrid officer may have to be present during commissioning to ensure that all necessary standards are met before the system is connected to the grid.

Details of the grid connection process are available on SP Group's website.

To minimise delays in grid connection, the Government encourages the timely commencement of the grid connection process and the prompt completion of the necessary applications and technical requirements by the relevant parties. This includes engaging SP Group on the feasibility of grid connection before commencing installation works and promptly completing the remaining grid connection procedures upon completion of the installation.

The Government will continue to work with SP Group and industry stakeholders to explore ways to further expedite the grid connection process.
