Brussels, 28th April 2010: On the 13th of April at Hotel Silken, Brussels, the European Wind Integration Study launched its final report with a discussion meeting of network and wind generation experts, policy makers and stakeholders. Project consortium leader Mr. Hubert Lemmens and project manager Dr. Wilhelm Winter welcomed approximately 100 participants to the meeting.
- the benefits of transmission network capacity in harnessing diversity in wind production across Europe and sharing the required backup generation sources;
- the need for a market model tool which accurately represents network physical limits in order to identify economic wind integration measures;
- the potential for increasing congestion in the immediate future on key pinchpoints such as cross-border lines and the quantification of the costs and benefits of relaxing these constraints;
- the quantification of system balancing costs and the best ways of acquiring these services;
- the urgent need to progress key reinforcements for both economic and security reasons, unblocking previously identified measures in national plans and adding new measures identified by EWIS;
- the need to use best practice operational techniques to maximize the benefit of existing network capacity;
- the need for TSOs to coordinate their use of such measures to avoid unwanted interactions between different network areas;
- the need to have harmonized grid code requirements for wind power generators; and
- the synergies between offshore wind connections and cross-border links for the longer term (2020-2025) development of offshore grids.
Guest speakers gave their perspectives on the study and how the issues identified could best be taken forward:
Mr Frans Van Hulle, representing EWEA and the TradeWind study, identified the complementary features of the EWIS and TradeWind studies and also areas where results from the studies are consistent. He highlighted the co-operation achieved between EWIS and TradeWind including the sharing of Europe-wide wind scenarios and network models. He identified the importance to the industry of harmonizing grid code requirements and welcomed the contribution that EWIS had made in taking this issue forward with the EWEA grid code group and the new ENSTO-E grid code initiative.
Mr Marcel Cailliau of Eurelectric recognized the benefits of the low marginal cost energy produced by wind generators as quantified in the EWIS report but also highlighted how the more volatile spot prices that would be caused by the integration of wind generation in Europe’s electricity markets were necessary to incentivise and fund the required flexible backup generation capacity. He warned that regulatory interventions in the market that might cap price spikes during low wind periods would cause “missing money” and deter establishment of the required backup generation. He therefore highlighted the importance of regulators recognizing these necessary aspects of future spot market behavior
Mr Jean Verseille identified how ENTSO-Es activities, see ENTSO-E website, have picked up the key issues identified in the EWIS study and how ENTSO-Es strategic activities are closely aligned with achieving the successful integration of wind power in Europes electricity networks. He highlighted ENTSO-Es strategic focus on delivering the required innovation and Reseach and Development, of ensuring adequacy of the integrated grid system, developing an integrated electricity market, and ensuring reliable system operation. In the specific case of the Ten Year Network Development Plan (currently subject to consultation) he explained how the reinforcements include not only the measures identified by TSOs in their individual national development plans but has also collated those measures which could bring pan-European welfare benefits including those identified by EWIS.
Mr Patrick Van Hove, European Commission Research Directorate, appreciated the need for a focus on near term issues but highlighted the importance of feeding into the longer-term research efforts necessary to achieve Europe’s sustainable energy vision. He noted that the data collated in EWIS and improvements implemented in the market model would be very valuable to other researchers and on-going projects. In particular, he highlighted the importance of developing the long-term strategic view of Europe’s electricity networks and so be able to answer questions concerning the form of Europe’s supergrid network and when to initiate its implementation.
Questions and discussions in the meeting examined results from EWIS and explored their implications for such topics as the prospects for new storage facilities, the importance of enhancing demand side participation and response, the benefits of offshore transmission networks, and the potential for new network technologies like multi-terminal voltage source converter HVDC. A key question raised was whether there should be a successor phase to the EWIS project or whether the new European regulatory and TSO organisations have now been established.
Closing the meeting, Mr Hubert Lemmens gratefully acknowledged the participation and support of the project’s stakeholders especially the European Commission DG-TREN.
