5 4 Empresa de Electricidade da Madeira, S.A. Serra de Água Socorridos Covão Curral das Freiras São Vicente Ribeira Brava Campanário Câmara de Lobos Sª. Quitéria The Socorridos Multipurpose System is the largest and most significant hydro engineering project in public water- supply, irrigation, and hydro-power in the Autonomous Region of Madeira (RAM) km of tunnels and open-air channels upper reservoir capacity of 7.500m3 hydroelectric plant (3x8 MW). Contribution to electricity production basically restricted to the rainy part of the year. The management of these infrastructures makes possible to transfer water from the north of Madeira (with major water availability) to the south of the island (where is located the majority of population) Socorridos Multipurpose System

6 5 Empresa de Electricidade da Madeira, S.A. Main goals: To transform the Socorridos Hydroelectric Power Plant - a winter-only power-station, manifestly dependent on rainfall into a reversible-function power plant used throughout the year; To contribute to install new renewables, namely wind farms; To improve the public water-supply system and of irrigation dependent on the southern arm of the North channel; Main components (projects): 1.Covão tunnel (upper reservoir) 2.Socorridos gallery (lower reservoir) 3.Pumping station 4.Water storage reinforcement Serra de Água Socorridos Covão Curral das Freiras São Vicente Ribeira Brava Campanário Câmara de Lobos Socorridos Multipurpose System Socorridos Hydro Power Plant reversible

7 6 Empresa de Electricidade da Madeira, S.A. Covão tunnel (upper reservoir) Socorridos gallery (lower reservoir) Pumping station Water storage reinforcement on Encumeada and Canal do norte tunnels m lenght, between Campanário and reservoir of Covão (7.500 m3), allowing a total storage capacity of m3. The Socorridos gallery has a capacity of m3, allowing to store the turbinated water in the hydro power plant of Socorridos. Based on 4 pumps of 3,7 MW each, and all auxiliary electromecanic equipment allowing to put the storage water in the lower reservoir to the upper reservoir, during the night (off peak period). The reinforcement of Encumeada and Canal do Norte tunnels, make possible an additional water storage of m3, wich enables a better management of hydro resources in Socorridos system.

9 8 Empresa de Electricidade da Madeira, S.A. Financing of the four projects (reversible system) EEM (50%) FEDER (50%)* * Under the terms of the Autonomous Region of Madeira's funding-programme POPRAM III (from the Portuguese "Programa Operacional Plurifundos da Região Autónoma da Madeira"). The joint participation of FEDER, approved on the 29th of July 2004, guarantees an incentive up to 50% of the total cost of the project, with the remaining cost being entirely assumed by EEM. Socorridos Hydro Power Plant reversible (*) – Received 15.2 Millions of Euros from FEDER Calheta Hydroelectric Reversible System – Calheta III

10 9 Empresa de Electricidade da Madeira, S.A. Why Calheta III? Calheta Hydroelectric Reversible System – Calheta III Limited capacity of Socorridos Reversible System for integration new renewables (only m3 of water storage capacity) Accumulated experience and confidence with Socorridos, specially in the pumping system (high height) To strongly contribute for the expected targets for 2020: 50% electricity production based on renewables, in line with orientation of regional politics for energy To constitute a strategic reserve of water, for public consumption, irrigation and the electricity system managing.
