creating the internal energy market in europe
DESCRIPTION
A report on EU electricity market rules, which must reflect the energy generation mix of the future and help usher in a flexible power system with a large-scale uptake of wind power and other renewable energy sources. The report recommends: 1- Creating a level playing field for renewable energy sources by tackling structural market deficits. 2-Creating functioning markets covering larger geographical regions within Europe so as to reduce the need to balance variable renewables like wind and solar 3- Developing intraday and balancing markets at national and cross-border levels 4- Creating new markets for 'grid support services', supporting the functioning of the grid to ensure a secure supply of electricity, instead of introducing market distorting capacity payments.TRANSCRIPT

Creating the internal Energy Market in Europe

Key findings • Structural market distortions
remain the main obstacle for the IEM and wind energy integration– Large incumbents, high market
concentration, regulated prices
• Support mechanisms for wind and RES should be seen in the context of unfinished liberalisation
• Exposure of wind generators to market risks require a level playing field
![Page 3: Creating the Internal Energy Market in Europe](https://reader033.vdocument.in/reader033/viewer/2022052620/5579f617d8b42abc2e8b4bef/html5/thumbnails/3.jpg)
Key findings (…continued)• Integration of large amounts of
wind in a cost efficient manner requires changing current market arrangements
![Page 4: Creating the Internal Energy Market in Europe](https://reader033.vdocument.in/reader033/viewer/2022052620/5579f617d8b42abc2e8b4bef/html5/thumbnails/4.jpg)
Key findings (…continued)• The EU Target Model (TM) does
not effectively enable optimal wind energy integration – No emphasis on wind integration
to the extent of NREAPs– No provisions for more
competition– Lack of emphasis on intraday
and balancing markets liquidity, harmonisation and interactions. These are wind energy integration cornerstones!
![Page 5: Creating the Internal Energy Market in Europe](https://reader033.vdocument.in/reader033/viewer/2022052620/5579f617d8b42abc2e8b4bef/html5/thumbnails/5.jpg)
Key findings (…continued)• Flexibility is the main feature of
tomorrow’s power system– Low marginal costs– Fast ramping power plants– Investment recovery over fewer
running hours
• Wind energy is able to contribute significantly to system operation and flexibility– Grid support services– System adequacy
![Page 6: Creating the Internal Energy Market in Europe](https://reader033.vdocument.in/reader033/viewer/2022052620/5579f617d8b42abc2e8b4bef/html5/thumbnails/6.jpg)
Policy recommendations1. Creating a level playing field2. Implementing the EU-wide
Target Model with large share of wind power
3. Assessing system adequacy properly in a renewable EU integrated power system
4. Ensuring cost-effectiveness of the future power system: a market-based approach for ancillary services
![Page 7: Creating the Internal Energy Market in Europe](https://reader033.vdocument.in/reader033/viewer/2022052620/5579f617d8b42abc2e8b4bef/html5/thumbnails/7.jpg)
Policy recommendations1. Creating a level playing field• Tackle market distortions rather
than only focus on RES provisions – Implement and transpose
properly liberalisation packages– Provide incentives for extensive
use of commercial power exchanges
• Design market rules that recognise the intrinsic characteristics of wind energy– Large control zones for
smoothing output variability– Shorter trading time horizons for
improved forecast accuracy and reduced balancing needs
![Page 8: Creating the Internal Energy Market in Europe](https://reader033.vdocument.in/reader033/viewer/2022052620/5579f617d8b42abc2e8b4bef/html5/thumbnails/8.jpg)
Policy recommendations2. Implementing the EU-wide
Target Model with large share of wind power
• Implement the EU-wide Target Model as a minimum– Provide integrated intraday and
balancing markets– Make the best use of available
transmission capacity
• TSOs must be encouraged to analyse all aspects of firm capacity from wind power and other RES in an integrated system at EU level– Challenge for capacity payments
![Page 9: Creating the Internal Energy Market in Europe](https://reader033.vdocument.in/reader033/viewer/2022052620/5579f617d8b42abc2e8b4bef/html5/thumbnails/9.jpg)
Policy recommendations3. Assessing system adequacy
properly in a renewable EU integrated power system
• TSOs must be encouraged to analyse all aspects of firm capacity from wind power and other RES in an integrated system at EU level
• Challenge for capacity payments

Policy recommendations4. Ensuring cost-effectiveness of
the future power system: a market-based approach for ancillary services
• Grid codes in Europe should first consider market options for ancillary services instead of compulsory requirements
• Establish grid support services markets to create additional non-discriminatory revenue streams for all generators
