8 Preliminary cable route Greece Crete Cyprus Israel The route consists of three sectors: Israel Cyprus section between Hadera site in Israel and Vasilikos site in Cyprus. Cyprus Crete section between Vasilikos site in Cyprus and Korakia site in Crete. Crete Continental Greece section between Korakia site in Crete and Attica region in Continental Greece.

11 Technology issues Request for Information has been prepared and distributed to the main manufacturers of HVDC equipment Four manufacturers answered the RFI: Alstom as a HVDC converter manufacturer ABB as a HVDC converter and submarine cables manufacturer Siemens as a HVDC converter manufacturer Prysmian as a sub marine cables manufacturer Siemens and Prysmian participated in RFI as a consortium.

12 Technology issues cable Mass Impregnated (MI) Cable The technology is available for voltages up to 600 kv and a transmission capacity of up to 2200 MW XPLE Cable The technology is available for voltages up to 320 kv and a transmission capacity of up to 1000 MW in one cable Preliminary conclusion: The project is technologically feasible based on MI 500kV 500 MW cables. Project schedule is determined by the submarine cable availability including R&D stage and manufacturing/installation duration Doing business with Israel summit 12

13 Technology issues converter Line commutated LCC LCC is the most widely adopted technology with many years of service experience but has limitation for bidirectional energy flow. Preliminary conclusion: feasible Self commutated VSC VSC technology allows bi-directional energy flow and true multi-terminal control. VSC converters have already implemented in a few projects, and planned for on-going projects at +/- 300kV and 350kV. Theoretically there is no limitation to voltage level and +/- 500kV VSC converter is feasible. Doing business with Israel summit 13

14 Technology issues configuration There are three main HVDC basic systems: Monopolar HVDC systems Bipolar HVDC systems Multi terminal HVDC systems Preliminary conclusion: At this level of information the best alternative is a bipolar configuration with monopolar bypass and sea electrodes. The final choice of the configuration will be optimized according to energy flow and reliability needs. Doing business with Israel summit 14

15 Network analysis. Study Objectives DC link impact study on existing transmission system. HVDC connection to the transmission system Steady State analysis of existing system with DC cable connection from the thermal limits and voltage constraints perspective Transmission expansion plan to make possible the connection of up to 1000 and 2000MW Power flow calculation of DC link power losses and voltage changes Contingency Analysis Doing business with Israel summit 15

16 Network analysis. Israel Dynamic Analysis In order to maintain stability after a fault, imported power should not exceed 30% of the local load. An HVDC Interconnection with a 1000 MW capacity is not expected to present a problem at any point in time. An outage of the HVDC Interconnection with a capacity of 2000 MW during export could: Risk the integrity of the Israeli power system during 3.7% of the time in the year Cause severe disruptions in energy supply during 5.5% of the time in the year The risk posed by an outage of a 2000 MW HVDC Interconnection could be reduced by lowering the capacity factor or by redesign of system protections.

17 Network analysis. Cyprus Importing power into the Cyprus system, maximum power loss of 225 MW may be tolerated. It will result in disconnection of 11% of the consumer loads for at least minutes. The disconnected consumers will be restored within minutes by starting the five peaking open cycle gas turbine units, provided that they are available. For a sudden loss of power import higher than 225 MW, the resulting shed consumer loads will require a substantially higher restoration time, ranging from 4 to 6 hours, depending on the system conditions, as large steam generating units will have to be committed. Doing business with Israel summit 17

18 Network analysis. Cyprus The maximum power that can be imported is between MW, but if one of the two DC cables is tripped during such an operation, at least 27% of the system load will be shed and the corresponding restoration time will be of the order of several hours, which is unacceptable. Higher import is not feasible, due to the constraint imposed by the minimum stable loading levels of the generating units. Doing business with Israel summit 18

19 Market analysis. Greece Greece is an electrical peninsula. Greek Wholesale Market has a weak correlation with the major European markets and exhibits higher level of wholesale prices All the northern neighbors of Greece have lower prices and are net importers to the Greek market Italy another electrical peninsula is the only stable net importer from Greece. Note: we do not examine here the feasibility of Crete-Greece interconnection, which is clearly proved already Doing business with Israel summit 19

20 Market analysis. Greece Electricity production costs in Israel in the medium perspective are going to be lower than the Greek ones This situation dictates the Greek market as a primary target for EuroAsia Interconnector project The Italian market is considered as a secondary target, (+) characterized by high level of prices and (+) much larger trading activity, but ( ) access to the market is limited due to the lack of transmission capacity Dominant power flow through EuroAsia Interconnector South (Cyprus, Israel) to North (Greece) Doing business with Israel summit 20

21 Market analysis Main scenarios Development plans of Cyprus, Greece and Israel based mainly on gas fired CCGT units and use of renewable energy sources We are expecting a stable gap of 7 8 $/MMBTU between Greek and Israeli NG prices in favor of Israel. It s equivalent to /MWh difference in marginal costs (operational variable costs) for modern units The price of Cypriot natural gas is less certain. We consider three scenarios which are dictated by three Cypriot gas prices possibilities Doing business with Israel summit 21

22 Market analysis. Scenario A No change Fuel prices in Cyprus are similar to the current level The marginal costs are the highest in Cyprus Cypriot export to other countries in such conditions is uneconomical, so Cyprus is going to be electricity net importer from the cable. Both Greek and Israeli electricity is competitive for Cypriot market, but Israeli electricity, due to their lower costs, has a priority Greek export to Cyprus is hardly possible as a stable business pattern Relatively small Cypriot market can't fully use the Cable capacity The remaining part of electricity is sold at the Greek market Doing business with Israel summit 22

23 Market analysis. Scenario B Gas parity scenario Fuel prices in Cyprus are similar to those in Israel. The marginal costs (operational variable costs) is highest in Greece. Greek export to other countries in such conditions is uneconomical, Greece is energy net importer from the cable. Both Cypriot and Israeli electricity is competitive for Greek market, nobody has a priority. Israeli export to Cyprus or Cypriot to Israel is hardly possible as a stable business pattern. Doing business with Israel summit 23

24 Market analysis. Scenario C Cypriot energy hub scenario Fuel prices in Cyprus are much lower than in Israel. The marginal costs (operational variable costs) will be lowest in Cyprus Cypriot export to both other countries Greece and Israel is economical, so Cyprus will be energy net exporter to the cable. Both Greek and Israeli electricity are going to consume Cypriot electricity This scenario dictates a need for construction of CCGT plants in Cyprus which will produce electricity mainly for export.
