The ITVC project partners including CWE-Nordic TSOs, Power Exchanges and EMCC would like to inform market parties that they have been working on the long clock change process over the last month.
Since all involved Power Exchanges and EMCC have different rules to handle the additional hour on 30 October 2011 (between 2:00 and 3:00 a.m. during the night), a potential for adverse flows in hours 3A and 3B was identified. This could also have implications for the other hours on 30 October. All ITVC partners have been working in close cooperation over the last month in order to mitigate possible adverse flows. The outcome of that cooperative work is that a security process to mitigate possible deficits will be tested beginning of week 43 between EMCC and all concerned Power Exchanges. Depending on the test results, the ITVC Steering Committee will take a decision for solution A or B explained below.
A In case the EMCC deployment for the long clock change is validated, there will be two new routines. Please note that they are exclusively valid for the shift from summer to winter time:
In hour 3 and hour 4, equal flows on the NorNed interconnector have to be sent to Nord Pool Spot and to APX. In case of two different values, the EMCC system will select the lower value for the two hours.
In hour 3 and hour 4, the flow direction on the interconnectors will have to be identical. If there is a flow from North to South in one hour and from South to North in the second hour, the EMCC system will calculate zero flow for both hours. Ramping restrictions towards neighboring hours will be followed.
B In case the new deployment is not validated, all ITVC parties have agreed to stick to the current ITVC process and let each individual capacity holder decide on the most appropriate fallback solution for their individual interconnector, such as shadow auctions, for example.
All market parties will receive final information on this process on Thursday 27 October in the morning.
