This deliverable reports the work carried out in the direction of defining models for forecasting the electrical energy consumption, electrical and thermal energy production as well as the flexibility of a Data Centre (DC) considering different time frames and system level granularities. The time frames of the forecasting process are the day-ahead (i.e. 24 hours ahead with one-hour granularity), intra-day (i.e. 4 hours ahead with half an hour granularity) and near-real-time (i.e. 1 hour ahead) while as system level granularity we have considered the IT servers and server room sub-system, cooling sub-system, renewable energy generation sub-system, and the entire DC.
