The stages in the Portuguese Electricity System (SEN) programming have the following sequence:
After the day-ahead wholesale market session has been closed, OMIE elaborates an hourly programme with the sales and
acquisitions wholesale market results (PDBC);
Next, the Overall System Manager (GGS) elaborates the
Base Daily Operating Programme (PDBF)
which consolidates the information presented in the PDBC with that relating to the bilateral contracts communicated by the Market Agents;
After running the process for the resolution of technical constraints identified in the PDBF, the GGS publishes the
Provisional Viable Daily Programme (PDVP)
which includes the changes introduced to resolve technical constraints and to provide rebalancing of production and demand;
After the closure of every Intraday Market session (6 sessions), the
Final Hourly Programme (PHF)
is drawn up, per Programming Unit, aggregating all firm transactions remaining after the resolution of the Intraday Market technical constraints;
After 8 P.M., and after every Intraday Market session, the Hourly Operational Programme (PHO) is drawn up.
This programme includes the transactions carried out in the organized market and through bilateral contracts which were
technically validated, the expected mobilizations of regulation reserve and all other mobilizations carried out by the GGS
up to its publication, 15 minutes before the beginning of every hour.
Final Hourly Operational Programme (PHOF)
at the end of the day programming period. This programme includes the transactions carried out in
the organized market and through bilateral contracts which were technically validated, the mobilizations of Provisional Reserve Programme (PPR) and all other programming
changes relating to processes for the resolution of technical
constraints and to ancillary services.
