The following guidance document, here, contains general information on System Services Compliance Procedures. If further information is required, please contact generator_testing@soni.ltd.uk.

From 01 October 2018 submission of a unit under test has changed with guidelines here.

Units must submit a suitable load profile request form before making any changes to their characteristics, making any software upgrades or before carrying out testing.

For Conventional Generation Units, load profile forms can be found here.

For WFPS Units, load profile forms can be found here.

For DSUs, load profile forms can be found here and an updated Application form can be found here.

For Interconnector units, the Signal List which include the signals required for the provision of System Services can be found here.

For Battery units, the Signal List which includes the signals required for the provision of System Services can be found here.

For DSU units connected in Northern Ireland, the signal List which includes the signals required for the provision of System Services can be found here.

For WFPS units connected in Northern Ireland, the signal List which includes the signals required for the provision of System Services via Emulated Inertia can be found here.
