A number of payments and charges are paid or levied outside the Single Electricity Market by the Transmission System Operators, SONI and EirGrid. Most of these are related to payments for services necessary for the secure operation and restoration of the electricity system. Other System Charges are intended to incentivise the optimum performance of generators connected to ensure efficient use of the power system.
The DS3 Programme is about developing solutions to the challenges of operating the electricity system in a secure manner while achieving 2020 renewable electricity targets.

SONI and EirGrid have published a DS3 System Services Contracts for Regulated Arrangements Recommendations Paper. The aim of DS3 System Services is to put in place the correct structure, level and type of service in order to ensure that the system can operate securely with higher levels of non-synchronous renewable generation (up to 75% instantaneous penetration).
