Requirements
» Timeliness› Is becoming even more important as people become more
interested in short-term forecasts (e.g. next 30 minutes at 5 minute increments)
» Standardized metadata
» Quality assurance / quality control

Closing remarks
» 3TIER does not collect the observations directly -> agnostic to where it comes from
» Meteorological observations cover only part of the data needs required for power forecasting (power data, turbine availability, etc)
» Data owners are generally very protective of their own data
