As a general rule, renewable energy producers rely on a Market Representative Agent to act as an intermediary with OMIE and REE for the management and optimization of their energy sales. However, it can happen that several weeks—or even months—pass between the moment a plant begins feeding energy into the grid and the start of its representation contract.
During this period, the various Last Resort Suppliers (CUR) provide a web platform that allows producers to manage their generation forecasts either through manual entries or by uploading a file in a specific format.
If generation forecasts aligned with the plant’s technology and geographic location are not available during this time, and thus not uploaded to the CUR platform, all energy produced is considered an imbalance, with the corresponding economic losses.
Gnarum offers producers a Forecasting service that automates the submission of generation forecasts to the CUR platforms of existing distributors (Iberdrola, Endesa, and Gas Natural).

La combinaciĂłn de los más avanzamos modelos meteorolĂłgicos internacionales (NWP), con un pool de algoritmos que cubren todas las casuĂsticas asociadas a la exportaciĂłn de energĂa de cada planta, permite optimizar la gestiĂłn de desvĂos desde la puesta en marcha.
