Citizens Advice's response to Ofgem's consultation on Market Wide Half Hourly Settlement (MHHS): Consultation on the governance, funding and operation of an Event Driven Architecture (EDA)
We think that both REC and BSC represent competent bodies to manage the logistical challenges of the governance, operation and funding of the EDA. We understand the new architecture is a hybrid comprising ElectraLink’s Data Transfer Network with minor modifications and a new EDA platform to meet the requirements of the MHHS Target Operating Model (TOM). We view ensuring a long term strategic fit that enables clear synergies with other services provided via the governance provider as a priority for Ofgem given the potential consumer benefits of the right approach. To this end, we think the EDA should be closely aligned to the BSC, half-hourly settlement reform and wider reforms in utilising metering to enable innovative settlement solutions. These are key developments that support access to markets and support competition which are potential drivers of efficiencies and uptake of low carbon technologies.
