2 . Context Red Eléctrica is the Spanish Transmission System Operator (TSO) Red Eléctrica was the first company in the world dedicated exclusively to power transmission and the operation of electrical systems. A pioneer in its field, the company occupies a position of leadership today in these activities. 2

3 . Context 3

4 . Context Electricity is not storable and instantaneous balance between production and demand is needed Excess of generation Excess of demand RED ELÉCTRICA DE ESPAÑA 4

5 . Opportunity for storage Storage as opportunity to integrate renewable energy, to improve flexibility, security and efficiency of electric system Need for renewable integration Storage: an open opportunity Need for improving system efficiency and flexibility Need for keeping security of supply 5

6 . Opportunity for storage 6

7 . Applications Non conventional Storage 1 2 FLYWHEEL ELECTROCHEMICAL STORAGE 7

8 . Non conventional storage Non conventional Storage 1 2 FLYWHEEL ELECTROCHEMICAL STORAGE 1 VOLANTE DE INERCIA FLYWHEEL Device that storages energy as movement (kinetic energy) Applications: Frequency stabilization Voltage stabilization Lanzarote Project: Power: 1,65 MW Time: 12 seconds 8

9 . Non conventional storage Non conventional Storage 1 2 FLYWHEEL ELECTROCHEMICAL STORAGE 2 ELECTROCHEMICAL STORAGE Device that storages energy as electrochemical potential (battery) Applications: Power-Frequency control Voltage control System flexibility ALMACENA Proyect (Carmona) Power: 1 MW Time: 3 hours 9

10 . ALMACENA PROJECT 10

11 ALMACENA is an innovation project led by REE(the Spanish TSO) and with A1223 Energy Solutions (now NEC ES) as technology provider. The consists of a 1MW, 3MWh grid battery system (GBS), includes a Power Conversion System (PCS) and is connected to the Spanish Transmission Grid in Carmona Substation (Sevilla) Dibujo / Foto del sistema 11

12 . Initial Targets ALMACENA project s main target is to analyze challenges and features of electrochemical storage systems connected to the grid 1 To especify and to define the energy storage system 2 To identify challenges in engineering and building MW 0:00 2:00 4:00 6:00 8:00 10:00 12:00 14:00 16:00 18:00 20:00 22:00 M 0 W Real Programado Bateria 3 To test technical capabilities (flexibility) for system operation 4 To get valuable experience and key aspects in O&M 12

13 . The LEGO ALMACENA system is highly modular Container with 32 Racks Every Rack contains 22 modules 13

14 . Online diagram ALMACENA is connected to transmission grid through the tertiary of a 400/220 kv transformer in Carmona s substation 14

15 . Functionalities 3 simultaneous control modes 1 Imagen Closed Loop Application: Power- Frequency Regulation (PF) 2 Imagen Profile Dispatch Application: Load Shifting (LS), for both Active and Reactive Power. 3 Imagen Closed Loop Application: Voltage Regulation (VR) 15

16 . Functionalities that can be mixed in real operation 16

17 . Control system Control systema allows to manage the system both, locally and remotelly Local control inside de container Remote control from any desk in REE 17

18 . Control system Control software for monitoring and control, adapted to REE needs 18

19 . Where we are? 1 Standar O&M afternec purchasing by NEC ES 2 Gathering leassons learned 3 4 Analysing performance Colaboration with Sevilla s University Colaboration with EPRI International benchmarking 19

20 . Where do we go? 1 Learning on Maintenance 2 Developing operation tools (long/ short term) 3 Modeling aging (key element for business models) 4 Going on with EPRI s colaboration 20
