Energy network price controls
Includes regulations, consultations and guidance on energy network price controls.
We set price controls to make sure energy network companies treat customers fairly, invest in improving their service and support the move to low-carbon energy.
The RIIO framework
Energy network price controls are known as RIIO (Revenue = Incentives + Innovation + Outputs), where:
- Revenue is how much money an energy network company can make
- Incentives encourage energy network companies to find new ways to improve their service
- Innovation means energy network companies finding new ways to provide a safe, reliable and sustainable network while offering value for money
- Outputs include safety, preserving the environment, customer satisfaction, social obligations, network connections, reliability, and availability
RIIO price controls encourage energy network companies to support Great Britain’s move to low-carbon energy. There are price controls for gas and electricity transmission, gas distribution, and electricity distribution.
