    1. 1. Accommodating a Growing Share of Electricity Generated by RES Hubert Lemmens Chief Innovation Officer Amsterdam 15 October 2013
    2. 2. Elia Group - reliable and resilient networks Ownership Elia • 100% of 380-150kV network • 94% of high voltage network (70-30kV) 50Hertz • 100% of 380-220kV network  34% of the German 380kV network  19% owner of the German 220kV network Age of networks Elia • Less than 15 years for 50% of underground cables • Less than 25 years for 50% of lines & substations 50Hertz • Around 10 years for 90% of the network (refurbished after German reunification in 1989) 2
    3. 3. Elia + 50Hertz Transmission = Top 5 in Europe Elia Group 110-380 kV lines and cables 13,431 km 30 tot70 kV lines and cables 4,800 km Substations Served territory (km2) 872 ~ 143,000 Direct consumers ~ 130 Inhabitants > 30m Staff (FTE) ~ 1,900 Regulated Asset Base (RAB) € 5,843m 3 3
    4. 4. Grid development: interconnections for market convergence and RES integration 4
    5. 5. Elia TSO – investments 2013 – 2022 Onshore: Major projects Decentralised production Meer, Rijkevorsel, Merksplas Offshore Reinforcement North border Additional PST, second circuit Gramme-Van Eyck Project Stevin for shore reinforcement Project Brabo in port of Antwerp Reinforcement BaekelandMercator-Doel Reinforcement “East loop” onshore wind Reinforcement South border • Investment around € 2,0 billion over the coming 10 years in the onshore grid • Offshore grid investment amounts potentially up to € 1,0 billion, first investments foreseen in 2013 • Main risk: NIMBY effect on permitting and timing. 5
    6. 6. 50Hertz – investments 2013 – 2022 Onshore Offshore – Baltic Sea • Investment around € 4,0 billion in the grid over the coming 10 years, spread over onshore (+/55%) and offshore (45%) projects • Offshore projects are mainly Baltic 2, Wikinger, Arkona-Becken Sudost 6
    7. 7. Germany: Ten Year Grid Plan Onshore German ten year grid development plan • Cooperation 4 German TSO’s for one grid development plan for Germany, accepted by BNetzA & Bundesrat • Measures to optimize existing routes • Grid expansion in new routes, including DC corridors • Total investment value foreseen at € 16,5 billion, of which € 4,6 billion is relating to DC corridors (A,C & D) 7
    8. 8. 50Hertz: First Offshore Grid Kriegers Flak Combined Grid Solution Project of European significance • Off-shore interconnection between Danish and German wind farms • Blueprint for North Sea offshore grid with • HVDC: ca. 600 MW, cable of 90km • HVAC: ca. 400 MW, cable of 30 km Figure 1 • Several added values for both countries - integration of RES - market development - secure system operation 8
    9. 9. USA: Atlantic Wind Connection First HVDC offshore-grid in the world • up to 6000 MW wind production • 2000 MW interconnector for 4 states • Participation: Eurogrid International (10%) • Partners: Google, Marubeni, Bregal Energy and Atlantic Grid Developers • Technological challenges under development: - • Multiterminal HVDC node HVDC circuit breaker Regulatory framework with FERC and PJM 9
    10. 10. Balancing: Increased need for flexibility to cope with variable RES infeed 10
    11. 11. Physical reality Forecast – actual: 5 GW Max-min generation : 23 GW Forecast – actual : 2 GW Delta peak in 1 week: 9 GW In Belgium: Wind ~1400 MW PV ~2200 MW 11
    12. 12. Low wind conditions (Germany) 12
    13. 13. Flexibility will be needed and Valued! 1 week wind generation in Germany Examples: important differences between minimal and maximal generation from intermittent sources 1 week solar generation in Belgium  TSOs need flexibility to keep the balance between supply and demand, by mobilizing all potential sources of flexibility within the grid, generation and the demand side!  In the real-time balancing market  In the Intraday market  Outside the balancing market, but in timeframes between DAY AHEAD and REALTIME: Potential for strategic reserves 13
    14. 14. Possible solutions: working on different axis Improve System Imbalances at the source (BRP): • • • • Single marginal imbalance tariff since 01/01/2012 Enhance balancing publications: e.g. wind and solar forecastings Continued market integration (NWE intraday, etc.) Etc. Diversify assets providing balancing services: • • • • • In 2013 - R1/R2 contracts revised to allow a variety of assets Load participating in supply of primary control (2013) Participation of aggregators in the supply of interruptible load (2013) RES, Storage Realise XB-synergies: • • • • • Participation of BE to iGCC (imbalance netting with 6 countries incl. DE) Intensive participation in the Network code drafting team Study into potential BE-NL XB synergies (with Tennet NL) Further investigations for iGCC evolutions Etc. 14
    15. 15. Elia Group Innovation Priorities 15
    16. 16. Smart Regulation needed • Current regulation remunerates assets, the hardware • System operation (the software): creates value for the market players • No return to System operators for the efforts they undertake • Need to evolve to incentive regulation sharing the benefits between market players and System Operators 16
    17. 17. Conclusions • Infrastructure developments face two main challenges: – – Fair return on investments Permits • Market requires new technologies and sophisticated services: – – – HVDC, meshed offshore grids Full flexible EU markets, close to real time gate closure But maintaining high level of reliability. • Innovation in System operation is key: – – – Novel business models Long term incentives for innovation Smart regulation 17
