The (In)Achievements of the EU Internal Energy Market(s)

  1. 1. The (In)Achievements of the EUInternal Energy Market(s)Jean-Michel Glachant(Florence School of Regulation)@ EEM13 / KTH in Stockholm29 May 2013
  2. 2. Agenda• (1st Part)Starting point: EU Internal Market Design for Gas• (2nd Part)Is EU Electricity Market Design bringing anotherdimension(s) ?• (3d Part)Need to revisit our EU Gas Target Model?
  3. 3. 3Pillar 1Enable functioningwholesale marketsFlorence School Target ModelPillar 2Tightly connectthese marketsPillar 3Enable securesupply patternsCommon foundationsImprove market effectivenessby realizing economic pipeline investments1st Part - OVERVIEW OF THE FSR TARGET MODELFOR EUROPEAN GAS MARKET INTEGRATION
  4. 4. 4EU Gas Architectures(To Enable FunctioningMarkets)• Two architecturesproposed by Florence School(1). Market Areas (= complete market fusion)• single price zone (entry/exit) + single balancing zonefrom import points to end-users• either structured as:*National (if “existing Wholesale markets” canfunction well alone); or**Multi-national (if cross-border cooperation requiredto get “functioning Wholesale markets” as 20 Bcm + 3different gas sources)
  5. 5. 5EU Gas Architectures(To Enable FunctioningMarkets)(2). Trading Regions (Balancing arrangements are left apart)• a single price zone (entry/exit) for wholesale marketswith congestion-freeinterconnection• BUT balancing zones are left to several national end-user zones.
  6. 6. 6To tightly connect the markets• Harmonisation of trading conditions (ETC)• They are measures to be implemented foremost inthe ENTSOG network codes in the areas of:– Capacity Allocation Mechanism– Congestion Management Procedure• open seasons, VP2VP-products, coordinated auctions for longerterm capacities, 1stC1stSfor the intra-day market, harmonizedcontract start dates, standards for secondary capacity trading…
  7. 7. 7– Nomination and Balancing• common gas day, harmonized nomination schedules, limits onre-nomination, …– Tariffs• harmonized date for change of tariffs, structure methodology,inter-TSO compensations within large zonesTo tightly connect the markets
  8. 8. 8COMMON FOUNDATIONS:Coherent Transportation Investments• Investments for market interconnections– Market based “open seasons” with pre-set evaluationcriteria– regulatory authority could add capacity needed forsecurity of supply or openness of markets (incl. for shortterm trade)• Investment within the markets (inside pricingzones), to be evaluated against congestion costs
  9. 9. Is this gas target model enough?• The ultimate European Union goal: a “unifiedenough” internal market– Hence a Gas target model– And a Electricity target model• But increase interactions between bothmarkets lead us (& me) to wonder…How much do these two markets designsinteract?

  13. 13. Design of trade for gas and elec.• Both gas and electricity have strong time andspatial delivery specificities (no Dropbox!)– Different economic values for time and space• Design of trade might simplify the traded products– First simplifying the commodity (to be traded)• Simplifying the products being sold• Simplifying the products being bought– Then defining a set of services complementaryto the simplified trade (= the “ancillary services”)

  15. 15. We said “market areas& trading regions” (as EU gas pillar 1)...• What does it mean now?Prices different at each trade point(nodal approach)Price the same inside a trading zone(zonal approach)• Transmission allocation entersinto the market clearing• Transmission allocation does notenter into the market clearing• Need less transmission servicescomplementary to trade• Need more transmission servicescomplementary to trade• Lower price liquidity • Higher price liquidity
  16. 16. ...the length of balancing periodis consequential tooPrices might differ at each time period(t)Price the same within several periods(n t)• Need less complementarytransmission services• Need more complementarytransmission services• Lower price liquidity • Higher price liquidity

  22. 22. Missing signals– Assume that to increase market liquidity, wesocialize temporal flexibility– Network tariffs do not reflect flexibility costs• Signals coming from the gas system areweakened

  30. 30. Conclusions• Basic design of trade (= defining spatial andtemporal characteristics of the commodities) is keyto efficiency and liquidity of markets• Coordination of transmission services and markettrading mechanisms is core of this key• Interactions gas / elec. Networks and Markets aretoo dense to ignore. They have to be taken intoaccount by the basic designs of trade >> redesignwelcome?
