23 Generation Increase of the Distributed Generation by reducing its size. 2. Increase of the system reliability: storing energy has the effect of segregation or also eliminate blacks. 3. Reduction of peaks in the system. Load based schedule of the system: asset management improved Aging extended: Reducing cost of equipments (reduction of power requirements) 4. Energy price arbitring in real time pricing situation 5. Frequency and voltage regulation.

24 Renewable Energies Characterized by its variability. 1. Ability of having a firm renewable generation with a high increase of disposal. 2. Provide ancillary services to transmission. Millions/ Year *Source: EPRI Wind Penetration Price Off- Peak Wind Generation 24

25 Transmission and Distribution Increases Grid reliability. 2. Increases effective capacity of transmission and distribution (high speed of charging and discharging). 3. Some assets become low- stressed. As a reliability tool, reduces faults. 4. Allows to shift investments in the grid because of the peak shaving effect. 5. Reduces grid congestion patterns, specially daily ones. 6. Increases capacity to distribute energy nearer to the consume so the technical loses in the whole chain value are reduced.

26 Final consumers Improvement of the control system 2. Reach to high rates of reliability that could compensate the impact that is going to provoke particular and uncontrolled distributed generation. 3. Gives the possibility of capturing distributed renewable energy, like the photovoltaic solar or the wind one, and use it after its storage, directly connected or not to the grid. 4. Optimize grid performing, specially if the end consumer can coordinate with the operation of the grid, for instance, peak shaving, peaks assumed by the storage systems. 5. G4V and V2G interaction, take advantage of the energy stored in EV, and have the chance to send this surplus energy to the grid when it is needed.

30 30 GENERAL VISITON OF GENERATION AND ENERGY STORING ENDESA s objective: 1. Diversificate its generation mix 2. High rate of technologies composed by: - Pumping technologies - Batteries - Other storing technologies that will allow us to generate and manage energy more efficiently. Canary Islands is a very attractive scenery to develope storing technologies that could allow us to increase the efficiency of the electric system management reducing fluctuations, intermittences that growing renewables are going to create in the Electric Insular Canary System.
