  • Successful Launch of Swe Common Synchronised Operations with Nwe Price
    North-Western Price Coupling of South-Western Europe Regions Europe SUCCESSFUL LAUNCH OF SWE COMMON SYNCHRONISED OPERATIONS WITH NWE PRICE COUPLING 4 February 2014. The South-Western Europe (SWE) and North-Western Europe (NWE) day-ahead price coupling project partners are pleased to announce the successful launch of common synchronised operations of NWE and SWE day-ahead markets. Full price coupling on the French-Spanish border will be launched at a later stage. This has been decided by the project partners, following common testing and alignment of Gate Closure Times. Both projects operate using the systems and procedures provided by the Price coupling of Regions (PCR) initiative. This launch is a significant step towards an integrated European power market. In pursuit of European day-ahead Price coupling, NWE and SWE have designed a step-by-step approach to integrate the Iberian market and NWE. Steps to integrate the day-ahead markets in the SWE and NWE regions have been underway since April 2013, addressing the joint testing of systems and operational procedures for the combined NWE and SWE regions. Alignment of timings in the SWE and NWE day-ahead markets successfully took place on 15 October 2013, when the Iberian day-ahead Gate Closure Time was switched to 12h00 CET. The penultimate step was achieved on 4 February with the go-live of common synchronised operations of the NWE and SWE projects for delivery on 5 February 2014. SWE uses the same PCR systems and operational procedures as NWE. For the time being, PCR will operate without offering capacity at the French-Spanish border to the price coupling, so the daily explicit auction on this border will be maintained as it is today.

In the two years since our last Demand Response Map was published, we have seen improvements in almost all of the countries analysed, but progress has been gradual. Markets are slowly being opened where they were once closed, the role of aggregation is becoming more defined, and market product requirements are becoming more accessible for Demand Response. However, there is still much work to be done and flexibility potential to be realised across the continent.
