Coronavirus (COVID-19) important information
In order to protect the safety and welfare of our customers and employees, we’ve paused the delivery of all non-essential and non safety-critical work. You can still complete an application form for our services. We’ll then send you a quote or give you an idea of how much the work will cost. Until the national restrictions change we’re unable to organise dates for us to carry out the work. We’re sorry for any inconvenience this may cause. If you’ve got any questions, please get in touch and we’ll be more than happy to help.

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.

Any questions?
Download our list of Frequently Asked Questions or have a browse through our Connections guides for more information. You can also email us your G98/G99 questions: G98_G99@ukpowernetworks.co.uk

Customers who were part way through the connections process before the 27th April 2019 can download our G99 Fact Sheet for in flight customers. You can also view our process flows for more information on the steps you need to follow for generation connection.
