A final decision published in October 2021 confirmed this decision. These determinations do not apply directly to Northern Powergrid, but aspects of the proposals are capable of application at Northern Powergrid's next price control, (ED2), which will begin in April 2023 In July 2021, Northern Powergrid submitted and published its draft business plan for the RIIO-2 price control period (i.e., April 2023 to March 2028) - If adopted, this plan would involve annual capital and operating expenditures of £642 million, a 36% increase relative to the £471 million average expenditure expected over the current price control period. The increase is primarily related to decarbonizing the U.K. energy sector A final business plan will be submitted in December 2021, ahead of the U.K. Gas & Electricity Markets Authority's draft in June 2022.
