Annual Report - EDP

: performance :By the end of the year, the total installed capacityin Iberia (excluding wind) was 13,808.6MW, outof which 5,699MW were from hydroelectric plantsand 7.643MW from thermoelectric plants.In Portugal, hydroelectric plants represent 53%of EDP Produção installed capacity.2012 was characterized by below average inflowsto the system, resulting in an hydrological indexat the end of the year of 0.48 in Portugal andof 0.46 in Spain, quite below the 0.92 and 0.81respectively registered in 2011.In this context, the Hydroelectric Ordinary regimegeneration of EDP Produção was 5,432GWhwhich is quite lower than the generation figuresrecorded in 2011 (10,485GWh). At the end of theyear, the storage reservoirs level representedabout 57% of its maximum capacity (49% in2011). Moreover, the Thermoelectric ordinaryregime generation of EDP Produção was stronglyconstrained by the high levels of imports andby the low usage of CCGT plants (1,507GWh in2012 vs 4,072GWh in 2011), having decreased by7.2% in the year to 10,155GWh, representing thesecond lowest value in 20 years. Sines plant, onthe other hand, in a context marked by low coaland CO 2prices, increased it operations regime,raising generation to 8.6GWh, which representsan increase of 26% compared to 2011.In Spain, due to a more competitive coal price (vs.that of CCGT), coal generation increased by 25%(6,714GWh in 2012 vs. 5,354GWh in 2011), whileCCGT generation decreased by 42% (1,598GWhvs. 2,754GWh). The availability of coal plants was91.9%, which confirms the proper functioning ofits operations, particularly taking into accountits flexible operations, given its complementarycharacter between coal and gas. The availabilityof CCGT plants was 94.4%, with frequentinterruptions due to market requisitions.In terms of existing power plants, the activityof the Carregado thermoelectric plant ceasedoperations on the 1st of April (710MW), havingstarted at the end of the year the first phase ofits decommissioning process. It is noteworthythe completion, during the month of March,the decommissioning works and environmentrestoration of the Barreiro thermoelectric plantalong with the corresponding signature of itsprovisional acceptance certificate.Regarding EDP Produção hydroelectricgeneration portfolio capacity, it is worthmentioning the conclusion of construction andassembly works of Alqueva repowering, havingthe two new generator groups (256MW) initiatedits trial period on November 26 and entered intooperation on December 2012.The construction works of the hydroelectricplants of Baixo Sabor (172MW) and Ribeiradio/Ermida (81MW) with conclusion scheduledfor 2014, along with the repowering of VendaNova III (756MW) and Salamonde II (207MW),with conclusion scheduled for 2015, and theconstruction of Foz-Tua (252MW), which will beextended until 2016, proceeded as planned.Baixo Sabor Hydroelectric Power PlantEDP - Annual Report 201241
