Our RIIO-T2 Business Plan is based on a Certain View - where we are able to identify the need and forecast the cost for intervention with certainty.
All future energy scenarios reveal that additional significant investment will also be required, but cannot always predict the timing or the precise details at the beginning of the price control.
This paper proposes the mechanisms to release efficient expenditure when we have that certainty. They are a means to manage the risk associated with events outside our control.
These mechanisms protect us from being forced to make decisions at the wrong time and so over or under forecasting our investment needs and protect consumers by only allowing us to invest when the need is certain.
