UK Grid Certification Is Changing EREC G98 and EREC G99
UK Grid Certification Is Changing; therefore prepare for for EREC G98 and EREC G99.
You may already be aware that there is a new standard coming into force called Engineering Recommendation (EREC) G98 and G99 on 27th April 2019. After that day any generators connected to UK distribution will have to comply. These two regulations, published by the Energy Networks Association (ENA), replace the G83/2 and G59/3 respectively.
- Current G83/2 will be replaced with G98 (systems up to 16A per phase)
- Current G59/3 will be replaced with G99 (systems over 16A per phase)
Any older G83/G59 devices (inverters) that are not compliant with G98/G99 will not be legally allowed to be connected to UK distribution network from May 2019 onwards.
These new standards will affect the connection and agreement process for all new solar, wind, battery storage, CHP and thermal generation plants that are planned for connection. The standard also now addresses integration of battery storage technology.
Please note: devices that fully comply with EREC G99 can be connected in advance of 27 April 2019 as they also comply with the pre-existing EREC G59 requirements.
