  1. The issue of loop flows Aleksandra Gawlikowska-Fyk Berlin, 4 December 2012

  2. Main powerflows in Europe Source: ENTSO-E Ten-Year Network Developemnt Plan 2012

  3. What are loop flows Loop flows / unplanned power flows / unannounced power flows • physical phenomena that occurs when generation and load centers diverge thus resulting in differences between commercial schedules and physical flows. Unplanned power flows result from: • internal transactions between Northern (supply of wind generation) and Southern Germany (demand) but also • exchanges within a common market area of Germany and Austria There are no explicit limits to these flows even if they are heavily using the networks of the neighbors.

  4. Sweden Export: 303.3 GWh Import: 1467.0 GWh Out: 277.5 GWh In: 1513.6 GWh Germany Export: 7233.6 GWh Import: 1983.5 GWh Export: 0.0 GWh Import: 59.6 GWh Out: 0.0 GWh In: 59.6 GWh Export: 2609.9 GWh Import: 195.3 GWh Out: 432.1 GWh In: 5135.6 GWh Ukraine Export: 3035.9 GWh Import: 224.4 GWh Out: 8261.5 GWh In: 44.0 GWh Export: 1284.5 GWh Import: 37.2 GWh Out: 3051.6 GWh In: 26.6 GWh Czech Republic Slovakia Physical and commercial power flows Source: Polish Energy Regulatory Office

  5. Problemsresulting from loopflows

  6. Winter 2011/2012 – critical • Problems associated with loop flows increased both in numbers and scale • massive renewable energy sources development not corresponding with grid development • Energiewende Source: Position of ČEPS, MAVIR, PSE Operator and SEPS regardingthe issue of BiddingZonesDefinition

  7. Why Poland and Germany will cooperate Regulation No 714/2009 and Congestion Management Guidelines • Point 3.1. capacity allocation at an • interconnection shall be coordinated by • involved TSOs. If commercial exchanges • between two countries affect physical • flow in third country – coordination • between all affected TSOs. • Point 3.2. coordinated congestion management method shall be applied by not later than 1 January 2007 in regions: Central Eastern Europe (Germany, Poland, Czech Republic, Slovakia, Hungary, Austria and Slovenia) 7

  8. Possible solutions Many initiatives aiming to address the problem: • The European Commission - study • ACER • ENTSO-E • BNetzA and Federal Ministry (internal) Many possible solutions: • short-term – better coordination and cooperation between TSOs related to operational security (re-dispatching) • mid-term – correct market design (adequate bidding zones) • long-term – infrastructure enhancement (interconnectors and internal grids) Phase Shifters  is it a real solution  Problem Shifters ???

  11. Improvements on German-Polish border • Phase shifting transformers: • better management of unplanned transits DE-PL-CZ • enhancement of transfer capacity on Polish synchronous profile. Expected NTC increase: • 500 MW for import and 1500 MW for export • greater security and reliability of the regional transmission network in Poland and in other countries of the CEE region • increased capability to accommodate more renewable energy resources in a safe and reliable manner • Third DE-PL interconnector: • strengthening market integration between member states • increasing NTC by 1500 MW for import and 500 MW for export on PL-DE/SK/CZ synchronous profile • improving network security - project contributes to increase of security of supply and flexibility of the transmission network
