8Socorridos 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
9Calheta 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.
