The Quality of Service Code for the electricity and gas sectors (RQS), approved by ERSE, defines:

• Obligations and quality of service levels to be fulfilled by operators
• Compensation to be paid when there are non-compliance

The RQS contains rules for network operators and suppliers, with regard to:

• Continuity of service: number and duration of interruptions
