The future of Power Industry & Prospects of Regional Energy Trading Dr Anastasios Garis Chairman & CEO LAGIE 29 April 2014 Electricity Market Operator S.A. – LAGIE SA

Key forces impacting the industry The European Electricity has been under pressure for the last few years, as depicted by the major Utilities financial performance Key forces impacting the industry Economic austerity adversely impacting electricity demand RES significant penetration driving out conventional capacity and reducing wholesale prices Retail prices increasing due to higher taxes and levies (primarily to cover RES costs) Relatively low coal prices driving natural gas generation capacity to extremely low levels (stranded assets in some companies) Electricity Market Operator S.A. – LAGIE SA

“The Problem” and “The Premise” The European Commission has embraced the problem and issued new Guidelines to be valid from July 2014 to the end of 2020 Issued Guidelines Gradual introduction of Market based mechanisms for RES “it is time for RES to join the Market” (A. Almunia) Gradual introduction of competitive bidding processes (pilot 2015-16) and replacement of FITs by feed-in premiums for some plants Promoting competitiveness of European industry Reducing the burden for a limited number of energy intensive sectors defined for the whole EU (e.g. Metals. Paper, chemicals, etc.) Supporting cross-border energy infrastructure to further the Single European Energy Market Focusing on projects that improve cross-border energy flows in less developed regions Permit aid to secure adequate electricity generation Encourage producers to build new capacity or prevent them from shutting down existing plants or to reward consumers to reduce consumption in peak hours “The Problem” and “The Premise” The remarkable growth of renewable energy over recent years, partly induced by public support, has helped to make progress on environmental objectives but has also caused serious market distortions and increasing costs to customers The Commission has reflected this in the new guidelines, which will be valid from 1 July 2014 until the end of 2020 Electricity Market Operator S.A. – LAGIE SA

Electricity Market Operator S.A. – LAGIE SA EUROPEX wellcomes the new Guideline which could potentially facilitate an effective integration of RES in the EU electricity market Power Exchanges and Trading platforms in Europe EUROPEX support for the Guidelines European solution regarding support for RES would further boost their development as well as diminish the impact of non- market based factors onto the electricity price. The main issues of current support schemes stem from the distortions they cause in the Market. These problems will be reduced by the Guidelines requirements regarding direct market participation, balancing responsibilities and reducing incentives to sell at negative prices. Already implemented market coupling projects harmonising power trading, increasing volatility, and increasing capability to cope with the intermittent nature of RES EUROPEX is a not-for-profit Association of European Energy Exchanges representing the interests of exchange-based wholesale electricity, gas and environmental markets with regard to developments of the European regulatory framework for wholesale energy trading and provides a discussion platform at European level.

Electricity Market Operator S.A. – LAGIE SA The European Power Exchanges (PXs) offer a wide variety of products to their customers to enhance market visibility and efficiency Example: ITALY GME’s mission is to organize and economically manage the Electricity Market fostering competition between producers, as well as economically manage an adequate availability of reserve capacity, under principles of neutrality, transparency and objectivity GME POWER (IPEX) ENVIRONMENT GAS Day-ahead Market Intraday Market OTC contracts platform Forward Market Derivatives Green certifictes Market Guarantees of Origin Efficiency Credits Market Emissions Allowances Market Green Certificates OTC registration platform Italian Gas Market Day-ahead & Intraday Gas Markets Forward Gas Market Long term brokering platform or compulsory sale of imports and royalties Gas balancing platform Spot Market Italy achieved in 2011 its coupling with the Slovenian market (price coupling) for trans border trading GME has agreed with EEX to use GME’s SMP as Index in EEXs derivatives business in Italy RES is operated by GSE. GME plays no part in RES GME is owned 100% by the State but its legal/operational model resembles that of private companies Electricity Market Operator S.A. – LAGIE SA

Electricity Market Operator S.A. – LAGIE SA The trend in PXs industry structure is consolidation whilst growing in scale and products bandwidth to enhance liquidity and risk mitigation (eex/epex as an example covering nine EU countries with plans to grow further) Structure of the German EEX PX (spot and derivatives arm) PX industry structure strategic direction PXs tend to offer paper and spot (derivatives/physical) trading products and perform the Clearing/Settlement tasks primarily under their own umbrella. The margins for energy trading are relatively low and would probably reduce further as the markets mature with time. It is most probable that energy derivatives trading across Europe would be operated by a few large companies who would provide the necessary liquidity for risk management. The entry of mega US energy traders and risk managers in Europe such as ICE, CMX and Nasdaq, would speed up the industry consolidation. It is unlikely that Local derivatives players will survive. Clearing and Settlement activities, whilst today offer higher margins, will probably go the same way. Spot energy trading would require local presence, although (through Coupling PCR) in some cases would be subsidiaries of regional PXs. Banks and Stock Exchanges have not made a mark in energy trading as the volumes are very small compared to that of stocks and interest markets. In the future, and when the volumes increase, they might try to enter the Derivatives energy markets as they do not have capability in Spot. They have no capability on the physical/spot energy markets. Bodies and Supervision for EEX Electricity Market Operator S.A. – LAGIE SA

Electricity Market Operator S.A. – LAGIE SA As another important step towards an effective integration of EU markets, EUROPEX has announced the full coupling between NEW and SWE regions by 14th May 2014 Μη σύγκλιση των τιμών μεταξύ Γαλλίας και Γερμανίας. NWE Project: Coupling of CWE, Scandinavia, Baltic Region and GB NWE and CWE are coupled since Feb. 2014 SWE (France, Spain, Portugal) coupling until mid 2014 Price Coupling of Regions (PCR) is an important step for the implementation of the internal energy markets in EU, to be accomplished by end 2014 through day- ahead and intra-day market solutions PCR optimises the use of cross-border capacities delivering signals for a more effective use of investment in the Power sector across Europe leading to: Increased liquidity Decreased volatility Drive for optimising buyers and sellers surplus across all involved markets The coupling of NWE with SWE will cover 17 EU countries accounting for some 75% of the EU power market Electricity Market Operator S.A. – LAGIE SA

Electricity Market Operator S.A. – LAGIE SA Despite the Market coupling in NEW/CWE and the consolidation of PXs across Europe, wholesale prices are not converging as yet Εξέλιξη ΟΤΣ σε Γαλλία και Γερμανία (2011-2014) Μη σύγκλιση των τιμών μεταξύ Γαλλίας και Γερμανίας. Η μη σύγκλιση των τιμών οφείλεται κυρίως στη μεγάλη διείσδυση των ΑΠΕ στη Γερμανία. Αυτό είχε ως αποτέλεσμα τις εξαγωγές ενέργειας από την Γερμανία προς την Γαλλία. Έτσι οι μέσες τιμές ενέργειας στα έτη 2012-2014 είναι μικρότερες στη Γερμανία από τις αντίστοιχες της Γαλλίας. Το Market Coupling επιτυγχάνει βέλτιστη χρήση των διασυνδέσεων και του ευρωπαϊκού κοινωνικού πλεονάσματος. Θα υπάρξει απόλυτη ταύτιση των τιμών μεταξύ δύο περιοχών που είναι συζευγμένες μόνο στην περίπτωση μη συμφόρησης των διασυνδέσεων. Κάτι τέτοιο μπορεί να επιτευχθεί μόνο με τη κατασκευή νέων διασυνδέσεων. Electricity Market Operator S.A. – LAGIE SA

Electricity Market Operator S.A. – LAGIE SA In Greece, the Electricity industry has also significant structural challenges Economic recession has stalled electricity consumption The whole electricity Market is subsidised at various degrees Drive to meet EU 2020 targets has resulted in expensive and uncontrollable RES growth with adverse effects in the RES industry liquidity as well as in the whole electricity industry structure Wholesale prices are kept at relatively low levels and display erratic behaviour Retail prices are rising (primarily due to extra taxes and levies) but the overall cost structure across the industry value chain has to be altered to allow full competition at the retail side Generation appears to be in oversupply whilst RES capacity continuous to increase The conventional generation sector industry structure excebits imbalances between the participants in terms of size, cost and fuel mix Electricity Market Operator S.A. – LAGIE SA

Electricity Market Operator S.A. – LAGIE SA Greece is expected to enter Market Coupling within the CSE region and from there to the whole EU power markets EU Commission has been decided to start a cooperation for elaborating a design for a day ahead market coupling on Italian borders using PCR. A Cooperation agreement for a Design Phase was signed end of 2012 between the following parties : Coupling advantages to Greece Increase of market liquidity Decrease of price volatility in the wholesale market Optimal use of the interconnections Leverage existing technical and processes architecture as already in use by the other PCR PXs On TSO side: ADMIE, APG ELES RTE Swissgrid TERNA On Power exchange side: BSP Southpool EPEX Spot EXAA GME LAGIE Electricity Market Operator S.A. – LAGIE SA

Electricity Market Operator S.A. – LAGIE SA NOME type auctions, due to start 9/2014, would allow retailers competitive access to the Market Introduction of NOME-type auctions of part of the incumbent PPC (Public Power Corporation) baseload capacity (PPC owns at the moment 98% of the supply market), to create new suppliers. NOME stands for “Nouvelle Organisation du Marché de l'Electricité”. It is a transitional reform of the electricity market. Eligible participants in NOME-type auction are limited to generators and suppliers.  Ensuring that implementation of NOME-type products is compatible and coherent with the privatization process of PPC and the creation of small PPC.   The NOME auctions and products will remain until the Greek electricity retail markets are fully competitive. The creation of a fully operational small PPC will constitute a necessary milestone in this regard.  To bring competition in the supply side of the electricity market, the auctioning of PPC capacity (NOME) would be brought ahead and started on September 2014.   Electricity Market Operator S.A. – LAGIE SA
