On this page, you will find the ESO RIIO-2 Business Plan, supporting annexes and our Delivery Schedule.

What is RIIO-2?

RIIO-2 is a performance-based model to make sure that we are delivering for consumers.

RIIO stands for Revenue = Incentives + Innovation + Outputs.

This is our first price control period as a legally separate ESO. It provides an exciting opportunity for us to demonstrate how we can be more transparent, agile and innovative to enable the transition to a sustainable energy future.

Our RIIO-2 business plan: facilitating the transition to new zero carbon emissions by 2050

Our ESO RIIO-2 Business Plan is founded on a vision for the next decade and beyond, focusing on how we must evolve to meet the challenges of the changing energy landscape and maximise benefits for consumers.

The plan sets out the activities we’ll deliver to achieve our ambitions, the investments we’ll make to meet net zero targets, how we’ll innovate for the future and the performance outcomes upon which we’ll be measured.

Ours is a stakeholder-led business plan, where by working together, we have made sure that what we will deliver reflects the priorities of our customers and stakeholders, to ultimately drive real benefits for consumers.

The activities in our plan will deliver significant value to consumers, culminating in net benefits of around £2 billion over the five years - a £3 reduction on every annual consumer bill.

Climate change is the challenge of a generation, and the time to act is now.
