Engineering Recommendations G98 and G99
Engineering Recommendations G98 and G99 come into effect on 27 April 2019. There are significant new requirements for generation of all sizes, including domestic scale photovoltaic generation, which connect to the distribution system. New G98 and G99 application forms have also been introduced.
If you are planning to undertake a generation connection or commissioning on or after 27 April 2019 you will need to comply with the new requirements and complete the new application forms below.
We will not be able to connect and commission any generation connection that does not comply with either G98 or G99, as appropriate, after midnight on 26 April 2019.
