Why is the RIIO-3 framework being brought into place?
Energy networks in Great Britain need extensive investment to support decarbonisation, clean energy, reliability, energy security, and a shift away from imported gas. RIIO-3 is intended to unlock that investment.
The framework aims to balance the need for investment with protecting consumers. It includes mechanisms to control costs, incentivise efficiency and innovation, and deliver value, not just for today’s customers but for the future.
Given the scale and urgency of transformation (Upgrading grids, accommodating renewable energy, ensuring resilience), RIIO-3 provides a stable, predictable regulatory environment so network companies can plan major upgrades with confidence.
