Harpen AG, the decentralised energy and renewables branch of giant German utility RWE, has bought Spanish renewables developer and operator Agrupació Energías Renovables SA (AERSA) from Barcelona-based insurance company Agrupació Mutua. AERSA will be Harpen's operative platform for the Spanish market. As part of the deal Harpen will inherit AERSA's 18 MW Acampo de Amijo wind plant, now going up in Spain's Zaragoza province. Aersa's wind activities are focused mainly in the highlands of Zaragoza, where Harpen brought its first Spanish wind station on-line, the 13.5 MW Grisel plant, in late 2001 after acquiring it from Germania Windpark. Both plant use NEG Micon 750 kW technology. RWE says AERSA, also based in Barcelona, will install a further 90 MW by year end, though it does not mention where. RWE says the AERSA acquisition "significantly expands [Harpen's] international commitment to renewable energy." Harpen is planning to bring 600 MW of wind on-line within the next five years. It has 160 MW of wind power under development in Italy "of which 100 MW can be installed within the foreseeable future." A further 450 MW of wind is being developed with two regional co-operation partners in north west and south west France (Windpower Monthly, May 2002). Harpen's renewable activities in Europe have so far been dominated by hydro power, with wind comprising just 26 MW of its 210 MW portfolio.
