La Castellana

active

La Castellana wind power project (the “Project”) includes the construction and operation of a 100.8MW wind power plant, a transformation substation and a 37 kilometer transmission line connecting the plant and substation to the national grid. The Project is located in the department of Villarino, near the city Bahia Blanca, Buenos Aires Province, Argentina. The Project will use 32 Acciona Windpower AW125/3.15MW wind turbine generators (WTGs),   each one linked to the on-site 33kV collector switchgear. The voltage will then be stepped up to a transmission voltage of 132kV at the on-site Project substation and will be evacuated through the Project transmission line which will finally connect to the Chañares substation. The Project will be developed and directly owned by CP La Castellana S.A.U. (“CPLC”, the “Company”) a special purpose vehicle organized under the laws of Argentina, predominantly owned on an indirect basis by Central Puerto, S.A. (“CEPU”, the “Sponsor”), Argentina’s largest privately-owned power generation company.The construction of the Project considers a multi-contract approach and as such, the procurement and installation of the wind turbines and the construction of the civil and electrical works are tasks covered under separate agreements between CPLC and different contractors or suppliers, ultimately supervised and managed by CEPU and by Ventus acting as owner’s engineer. During operations, Acciona will provide operating and maintenance services to the WTGs and CEPU will provide full corporate, operation and maintenance services to the Project.The Project will sell power through a 20-year Power Purchase Agreement (“PPA”) with the Compañía Administradora del Mercado Mayorista Eléctrico, S.A. (“CAMMESA”), awarded under round 1.0 of Renovar, the new renewable energy program launched by the Government of Argentina in 2016. The PPA with CAMMESA is USD denominated (with payments made in local currency).
