2 Contents Introduction, objectives, methodology Identification of interconnection scenarios +1 GW & +2 GW presented today Assessment of the investment costs of interconnection links Assessment of the investment tcosts associated dto the internal reinforcements within each involved country (Algeria, Morocco, Portugal, Spain) Identification and assessment of several technical options for each interconnection scenario 2

3 1 Introduction, objectives, methodology

4 Objectives & assumptions Objective To assess the grid investment costs associated to an increase of +1GW, +2GW, +3GW of transit from West Maghreb (WMA) (Morocco and Algeria) towards France through the Iberian Peninsula (IB) South to North flows Reference scenario: Main assumptions Networks to be analyzed are the Moroccan, Algerian, Portuguese and Spanish ones The French network is not considered, although the required interconnection links between Spain and France are included. Catalonian part of Spain and South East part of France (Marseille) Basque part of Spain and the south part of Bretagne (Nantes) 4

5 Methodology Build the reference scenario Network TYNDP, National Plans & TSO inputs Expansion Planning scenario Summer peak demand with high renewable generation in the south of Spain Compute the NTC value between West Maghreb and Spain France border, for the reference 22 scenario. Available transit over the commercial transactions already foreseen in MW between Spain & France since the FR SP 4GW NTC are fully loaded by Portuguese Spain renewable export requirements 700 MW between Morocco & Spain (N 1 criterion on the AC cable) 0 MW between Algeria & Spain WesternMaghreb France NTC is therefore considered to be zero. The reference base case for the study: 4 GW of exchanges SP FR 0 GW of exchanges MO SP 5

24 4c Assessment of internal reinforcements Morocco & Algeria

25 TITLE OF THE PRESENTATION Objectives & Methodology 09 5 Objective is to evaluate the reinforcements required in Morocco and Algeria to evacuate power from generation sites to submarine cables. Reinforcement depends on Power transferred, location of generation sites and connections of submarine cables. Study is performed for the 15 scenarios identified Definition of reinforcements required on basis of: Distribution of generation and exportation as defined in scenario AC load flow calculations in both N and N-1 conditions Respect voltage magnitude constraints and branch overload criteria defined by the TSOs Determination of losses for each scenario on basis of OPF Dynamic analyses are out of scope 25

27 Additional Generation Algeria: spread among 9 different power plants Morocco: occo concentrated ce in Agadir, Laayoune and Tizgui 27

28 Internal Network Reinforcements Algeria and Morocco Internal Reinforcements.14 8 Algeria (+1GW, +2GW) Minimal reinforcement needed (total cost of 4MEUR) Transmission i losses are not highly impacted by the additional generation/export (between 2 and 4% of power exchanged) Reason: Highly meshed network and distributed generation 28

29 TITLE OF THE PRESENTATION Internal Reinforcements 09 9 Morocco (+1GW) Investment required: 340km of 400kV line Cost of investment around 120MEUR Losses around 8% of power exchanged Reason: Generation far from submarine cable Relatively linear and weak HV network 29

30 TITLE OF THE PRESENTATION Internal Reinforcements 09 0 Morocco (+2GW + 3GW) Significant investments in network reinforcements: scenarios with up to 3000 km of new OHLs Cost between 600MEUR and 1000MEUR Level of transmission losses are very high Level of losses are prohibitive in certain scenarios (up to 20% of power exchanged) Additional problems may arise in these scenarios (such as power system stability issues) Reason: Generation far from submarine cable Relatively linear and weak HV network 30
