3 Endesa. Main Figures Endesa is the leading company in the Spanish electricity sector and the largest private electricity multinational in Latin America. Enel Group, which owns 92.06% of Endesa s share capital, is a multinational group based in Italy, a leading integrated player in the power and gas markets of Europe and Latin America. Presence in: 9 countries Installed capacity: 39 GW Output: 141 TWh Energy Sales: 176 TWh Distributed Power: 194 TWh Gas sales: 55 TWh Customers: 25 millions Employees: Endesa countries

4 Endesa in Spain. Main Figures Endesa is a vertically integrated company Data 2012 Generation (1) Transmission Distribution Supply Market Share Endesa LIBERALIZED REGULATED Monopoly REGULATED LIBERALIZED REE (System Operator) 32% -- 40% 37% (1) Conventional Generation

5 Generation Mix in Spain Conventional Generation Total Installed Capacity in Spain: 69 GW Endesa Installed Capacity: 22 GW (32%) Endesa Production in Spain Renewable Generation Total Installed Capacity in Spain: 38,5 GW Endesa Installed Capacity: 1,8 GW (5%)

7 The Energy Management Centre handles the technical and economic operation of Endesa s power plants, aiming to maximize profit: Main Functions BIDDING Hydrothermal Optimisation Bilateral wholesale transactions Wholesale power markets trading: Day-ahead, intra-day, transmission constraints, secondary, tertiary and imbalances Cross-border trading for the Iberian Peninsula REAL TIME OPERATION Scheduling monitoring AGC operation System restoration, outages and contingencies management Renewable production monitoring The EMC got the ISO-9002 Certification in 2002

9 The Control Centre Besides the intraday and real- time markets, the operators at the Control Centre are in charge of the plant schedule dispatching, the operation of the AGC (Automatic Generation Control) and the monitoring of the units schedule fulfillment The Control Centre monitors and controls 18 thermal units, 7 combinedcycle units (two of them in Portugal), 4 nuclear units, 6 pumping-storage plants and 152 hydro basins (243 units). In addition, Endesa Real Time System monitors 3 shared nuclear units Dispatching Services were provided to 63 wind farms and 5 hydraulic plants belonging to EGPE (1490 MW of installed capacity ) and also to 6 participated cogeneration plants (98 MW of installed capacity) Real-time demand, renewable production and network stability are monitored as well

10 The Control Centre The grid is operated locally at the thermal power plants and at the hydraulic control centers. The Control Centre coordinates the power plant and substation maintenance when a different grid owner (typically REE) is involved. Applications to REE are done for short-term maintenance of transmission network elements The Control Centre has an active participation in the System Restoration process, coordinating Endesa power plants according to REE instructions. They also update system restoration plans and instructions, both for local or national black-outs After a blackout, all Generation and Distribution control centers in Spain, coordinated by REE, should perform several actions to minimize the impact on the consumers. As the last national blackout happened in 1981, procedures updating and operators training are the only activities currently running on this topic

12 Real Time Control System The Endesa Real Time Control System is an ABB Network Manager 3 upgraded in 2009 from a previous ABB SPIDER installed in 2003 The control system receives 6900 analogical signals, indications, 720 meters, sends 90 orders and provides a set of advanced applications for generation monitoring and operation The three basic blocks of the system are: SCADA, Generation Manager System (GMS) Applications and the Historian and Data Warehouse (UDW) The main GMS applications included in the System are Automatic Generation Control (AGC), Reserve Monitor (RM) and Voltage Monitor (VM) The control system is linked to the off-line bidding systems to gather market information and to the settlement system to dump real time unit productions. The application used for this exchange is Data Communication Interface (DCI) Applications AGC Infrastructure Graphical Data Engineering Network Manager Graphical User Interface GMS Applications External Data Exchange Reserve Monitor SCADA Communication Front-End External Applications & Systems VM Historian and Data Warehouse

13 Hot Emergency Center The whole system is redundant and is fully duplicated in an emergency location a few kilometers away The Hot Emergency Center is constantly in contact with the Main Center and continuously receives logs of the database updates to keep its databases up to date

16 Endesa AGC does not need to do a schedule optimization (DE) as this is done by the market Customized AGC Due to the special characteristics of its regulation resources and the RCP (Peninsula-wide Distributed Regulation) response criteria, Endesa AGC needs to use a different and specific LFC algorithm Standard LFC algorithm: ACE is distributed among the units proportionally to their current reserve or to their ramp rate Endesa s algorithm: Developed by Endesa and an University Institute Firstly tested in an offline simulator (Matlab/Simulink developed). Designed to meet RCP requirements The main improvements of this algorithm are: Minimize the fuel consumption by distributing the area requirement economically Minimize unit wear and tear (thermal stress) by minimizing changes in unit setpoints Comply the speed requirements imposed by RCP avoiding penalties because of underperformance
