8 Socorridos Hydro Power Plant reversible Calheta Hydroelectric Reversible System – Calheta IIISocorridos Hydro Power Plant reversibleFinancing 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.(*) – Received 15.2 Millions of Euros from FEDER
9 Calheta Hydroelectric Reversible System – Calheta III Why 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 energyTo constitute a strategic reserve of water, for public consumption, irrigation and the electricity system managing.

19 Calheta Hydroelectric System Calheta III - New reversible system Main Components4 - Penstock/pump up pipe1500 mm steel tubing3.460m length, ensuring a dual role, functioning either as penstock (powering at peak load hours) or as a pump up pipe (pumping water during load diagram’s valley hours from Calheta and Paul stations to Pico da Urze’s bayou).5 - Water Pumping Station of Paul2x150 kW electric pumps will be connected to the penstock/pump up pipe, through a conducting stretch allowing, this way, to pump the collected water by Paul I water channel (Levada do Paul I), below the Pico da Urze dam, and also by Paul II water channel (Levada do Paul II), both to Pico da Urze bayou.
20 Calheta Hydroelectric System Calheta III - New reversible system Main Components6 - Paul II Water Channel (Levada do Paul) Expansion10,6 km length between the Juncal stream (Ribeira do Juncal) and the forebay of Paulthe work will be done only between the beginning and km 8,6 and will consist in raising about 25 cm the side walls of the water channel in order to increase its transport capacity.7 - Paul Old Water Channel (Levada Velha do Paul) Expansionmain source of supply to Pico da Urze’s bayou1.600 meters length , between the Lajeado stream (Ribeira do Lajeado - where it takes in the water) and the Alecrim stream (where it gives back the intake water)The work will consist in building a channel of variable section (in concrete material) in order to increase the carrying capacity of the water channel and also in the installation of a restraint of solid material in the water intake area, giving it back in the right bank of Pico da Urze’s bayou.
21 Calheta Hydroelectric System Calheta III - New reversible system Main Components8 - Lombo Salão Water Channel (Levada do Lombo do Salão) Renewal1.690 meters long, located between Calheta I Hydroelectric Power Plant and Lombo do Salão forebayThis refurbishment aims to reduce water flow losses during its path, increasing this way, the water delivery to irrigation and adduction to Calheta II Hydroelectric Power Plant (Central de Inverno da Calheta - Calheta II).
22 Calheta Hydroelectric System Calheta III - New reversible system Expected Results - Electricity29 GWh (about 30% of annual average hydropower production), of which 18 GWh will result from direct water exploration and the remaining 11 GWh will be the result from pumped water flow, using wind energy resources.Integration of more 25 MW of wind power, with an estimated annual production of about 60 GWh (equivalent to about 7% of the total production in 2010 in Madeira Island).
