The WIT system was established to aggregate inside information as described by art. 4 of REMIT, reported by the energy market participants holding production units connected to the electricity system, in one place.
The system allows to aggregate information on planned and unplanned outages in one place and to provide information on current and future available production capacity. System participants have a possibility to report inside information required by art. 4 of REMIT on the GPI website.
Every participant, after receiving login and password, gains access to the system and a possibility to report UMM for its production units. The reported information on capacity outages are thereafter graphically presented in the record of planned and unplanned outages and aggregated by totalizing all outages for any single day.
The record of UMM information presented on the GPI website together with data on the condition of the electricity system and commercial information from exchange markets should strongly enhance the energy market transparency and facilitate the trading decision making process.
