System Adequacy Retrospect 2007 published

The System Adequacy Retrospect 2007 report concludes that there was certainly enough generating capacity available in 2007 to cover the demand with the usual level of security.

The actual pace of development in generation facilities balances the continuing growth of load and peak demand. The analysis of the commercial or contractual congestions on cross-border lines shows that the eastern part of UCTE in Central Europe was still the main area of congestion. Generation Adequacy In 2007, Remaining Capacity had its minimum value in November with 71.5 GW of Net Generating Capacity reliably available on top of the Load. It reflects the cold temperature at the end of November 2007 that resulted in an unexpected high load. The lowest value of the Remaining Margin was observed in November due to cold temperatures in the second half of the month which increased load much more than expected. The level of the minimum Remaining Margin in 2007 was 5.3% of the Net Generating Capacity, close to the 6-year average value of 5.7%. The high level of the minimum Remaining Margin in 2006, namely 7.6%, was exceptional and due to mild temperatures all year long. In 2007, fossil fuel generation increased the most, namely by 43 TWh. This is related to the decrease of nuclear power generation by 42 TWh. Renewable energy sources (RES) generation increased by 25 TWh and counted for 5% of the total generation on the UCTE grid. In 2007, about 140 TWh have been produced with renewable energy sources, excluding hydro. Almost 70% of the UCTE RES generation (excluding hydro) has been generated in Germany and Spain. Wind power generation counted for 60% of the RES generation on the UCTE grid. Transmission Adequacy The analysis of the commercial or contractual congestions on cross-border lines shows that the eastern part of UCTE in Central Europe was still the main area of congestion. Notably, interconnection lines around Hungary have been used at their maximum capacities almost 100% of the time in 2007. One additional interconnection line between Former Yugoslavian Republic of Macedonia and Greece has been achieved in 2007. New or upgraded components led to an increase cross-border capacity from France to Belgium and between Portugal and Spain.
