Country Header Service Title Definition Source
gbAD_MWdemandAdjusted DemandA measure of the true GB electricity demand accounting for generation which is embedded in the distribution networks and not metered by the Transmission System Operator. This includes the effects of solar, wind and non-renewable peak generation. AD_MW = ND_MW + EmbSPV_MW + EmbWind_MW + EmbNR_MWAMIRA
gbADF_MWdemandAdjusted Demand ForecastAmira's own forecast of Adjusted Demand.AMIRA
gbDFS_MWdemandDemand Flexibility ServiceThe volume of demand supression requested or provided through the National Grid demand fleixibility service.AMIRA
gbEmbNR_MWdemandEmbedded Non-renewableAmira's own estimate of non-renewable embedded generation over evening peak; this is modelled using historic metered data and applies over the winter period only. AMIRA

gbEmbSPV_MWdemandEmbedded SolarAn estimate of the total generation relating to small to medium scale solar photovoltaic. Sites are typically small and embedded in the distribution system. They therefore do not have transmission system metering and the generation must be estimated to enable short-term trading and network operations.PV_Live
