TNEI delivers G99 training as part of 2019 training programme

27 Mar 2019

Last month TNEI’s experienced consultants Jonathan and Ali delivered an in-depth training session to industry professionals on the new Engineering Recommendation (EREC) G99.

EREC G99 was issued in July 2018 by the Energy Networks Association (ENA) following the assimilation of the EU Commission Regulation on harmonising network standards into GB Distribution and Grid Codes. It has been written to comply fully with RfG as well as including other requirements for connecting into the GB Power System.

G99 sets out a system of generator classification, based on rated export capacity (in MWs) and connection voltage, and defines generator configurations either as power generating modules or as power generating facilities. The manner in which technical compliance requirements are applied and demonstrated depending on these issues is also explored within this document.

The new G99 application form should be used for all applications where the date of connection is on or after 27 April 2019.

Our detailed training session covered need to know information about the changes from G59 to G99 including type classification, technical requirements, connection arrangements and the compliance processes for each generation type.

The session was delivered in an interactive format to allow attendees to gain better understanding and to enable them to apply the learnt knowledge to their scenarios. The course was well received by attendees with 100% agreeing they would recommend it.

The next G99 training session will take place on the 8th May at TNEI’s Manchester office. For further details or to book your place, please get in touch with our training team at or call +44 (0) 161 233 4800.
