In the frame of the outage planning coordination project (OPC), ENTSO-E Network Code Operational Planning and Scheduling requires TSOs to establish a common medium- and long-term outage planning process based on predefined standards with the following key objectives: ENTSO-E wide harmonization of regionally differing outage planning processes.
All TSOs of each capacity calculation region shall jointly set-up a regional security coordinator and establish rules governing its operations or appoint another regional security coordinator (RSC) to perform regional outage coordination.
TSOs already perform successful Outage Planning activities for areas defined over years of experience, however there is not yet a commonly agreed process, regarding the implementation of the RSCs in outage coordination, to be followed among all ENTSO-E TSOs. Therefore, ENTSO-E setup the “TSO coordination strategy implementation with RSCs” project with the goal to implement the future TSO coordination strategy as described in the ENTSO Policy Paper released in November 2014. The project aims at building an outage planning and coordination process based on already existing outage planning coordination within TSOs and experience from pilot phases and dry runs.
Coreso is working closely together with TSCNet, who is leading the working group for this coordination service. TSOs and 5 RSCs are collaborating to design these common practices and helping to develop the methodology for outage planning coordination, which will be the basis for a dry run.
Currently, TSC TSOs started a dry run, consisting in the merging of the outages for weekly and monthly process, which allows a systematic check of the planned outages and ease coordination among TSOs.
Coreso TSOs joined the experimentation end of 2016.
Furthermore, this process was enriched with new approaches :
These new approaches were tested during 2 “one month” dry runs organized in October and November 2016. Following the experiences gained from them, the methodology has been improved and some realistic timing have been proposed.
26 TSOs and 5 RSCs are involved.
In 2017, a week ahead experimentation will be proposed in 3 phases :
In the meantime, the methodology will be improved in order to define a timing for the process compliant with outages planning internal TSOs organization.
