EREC G99/NI details the requirements for the connection of generation equipment in parallel with public distribution networks on or after 27 April 2019. This Engineering Recommendation sets out the specific technical requirements depending on the type and size of the ‘Power Generating Module’.

In some cases with older generators, it is necessary to install additional equipment in order to comply with some of the requirements such as

·        Power Quality – Voltage fluctuations and Flicker

·        Power Quality – Harmonics

·        Reactive Power Capability

·        Frequency Range Capability

·        Limited Frequency Sensitive Mode – Over frequency

·        Active Power Set Point Adjustment

·        Fault Ride Through

·        Frequency Response Tests

·        Automatic Output Power Adjustment with Falling Frequency 


In addition to the above there is a requirement for a SCADA (Supervisory Control and Data Acquisition) facility for NIE Network to monitor and control the ‘Power Generating Facility’.

We have solutions for all types of generation including older induction units fitted to wind turbines such as Vestas V27, – V5, Micon, Fuhrlander, etc.



The DC0079 Accelerated Loss of Mains Change Programme is on the cusp of being rolled out by National Grid ESO and the UK DNOs (Distribution Network Operators) and iDNOs (independent Distribution Network Operators) to accelerate compliance with the Distribution Code.

The purpose of the initiative is to consider Loss of Mains (LoM) protection and their settings. The aim being to reduce the risk of inadvertent tripping and reduce system balancing issues by giving National Grid ESO greater latitude with regards to system RoCoF limits.

Your generator will have been connected to the Distribution Network under technical standards that require it to be tripped off at times of network disturbances. This is commonly referred to as the “G59 trip” or “G59 relay”, as G59 was the number of the Energy Networks Association Engineering Recommendation adopted by all DNOs/iDNOs. When your generator was commissioned, the G59 relay would have been programmed with the settings prescribed at the time, then tested and possibly witnessed by the DNO/iDNO.

As more and more distributed generation as been connected to the grid, concerns increase about the amount of generation that can be lost during a system disturbance, due to the G59 relays doing what they were programmed to do. As well as that, nationwide experience has shown that Vector Shift loss of mains protection has not provided results as predictable as had been hoped for.

The DC0079 programme aims to reduce the likelihood of large amounts of distributed generation being lost on system disturbance by making changes to settings in G59 relays to reduce the sensitivity to tripping, and to migrate any relays still using Vector Shift onto Rate of Change of Frequency (ROCOF)

National Grid ESO and the DNOs/iDNOs will shortly start to send out invitations to participate in the programme. The set of slides below provided by National Grid ESO and the Energy Networks Association, on behalf of all DNOs/iDNOs gives the background to the programme, as well as the proposed method and timescales of implementation.
