G59 to G99
As of the 26th April, the Energy Network Association (ENA) G59 regulatory standard for distributed generation connections, will be replaced with G99.
Whilst many things remain the same, we think something to note on the new application is the much-improved ability to capture more diverse information on projects.
Co-Located Energy Generation & Storage Assets
For example, there are sections for a wide range of generation and storage asset types, combined with a range of network connection options.
We believe this will help to facilitate more complex installations, projects where maybe you need to install co-located assets, e.g. PV & Storage, with an imposed export constraint (requiring a G100 export management system.)
This is precisely where the future of behind the meter generation and storage is - complex, co-located, and export constrained.
The Need for Control
This will require a control system that is both G100 compliant and has the capabilities to control multiple assets, and overcome physical constraints.
Solving these challenges is at the core of Argand’s GridGEM G100 system, currently controlling over 50MW of assets across the UK.
Fault Level Calculation
One element within the G99 application that will cause some headaches is the requirement to calculate fault level currents & other technical calculations. We can solve this through our G99 application consultancy service which will utilise our engineering capabilities to ensure applications are correct and have everything that the DNO requires.
