On 29 March 2019, we published draft versions of our Business Plan Data Templates (BPDTs), Cost Benefit Analysis (CBA) templates, Network Asset Risk Metric (NARM) templates, and all associated instructions and guidance.
These were used by gas and electricity transmission and gas distribution network companies when submitting draft RIIO-2 business plans to the RIIO-2 Challenge Group in July 2019. We also issued further updates in August 2019, which will be used by gas and electricity transmission and gas distribution network companies when submitting draft RIIO-2 business plans to the RIIO-2 Challenge Group in October 2019.
This is a final set of BPDT, CBA and NARM templates, and all associated instructions and guidance for gas and electricity transmission and gas distribution network companies to use when submitting final RIIO-2 business plans to Ofgem in December 2019. The IDP guidance and CBA templates were updated in line with the recent BEIS Carbon price values (BEIS website)
