Connection of Generation < 3.68kW (G98)

Engineering Recommendation G98

On 4th August 2008, the Health & Safety Executive issued a Certificate of Exemption that effectively relaxes the timescales for notifying a DNO when comissioning Small Scale Embedded Generation (SSEG). The DNO must still be notified but in the case of SSEG this no longer needs to be before, or at the time of, comissioning. Notification must now be made within 28 days of comissioning. Once connection forms have been completed they should be sent to the DNO in your area, ENA is not able to process these documents. You can find out who your DNO is on our Who is My Network Operator? page. 

Please note that from 27 April 2019 only equipment compliant with G98/G99 is accepted for connection to the networks due to the European Network Codes Requirements for Generators (RfG) legislation that come into effect
