Integration of renewable energies into the Iberian electricity market

Prof. Javier Contreras
University of Castilla-La Mancha, Spain


Since the 1990’s wind and other renewable technologies have a growing presence in the energy mix in Spain. The incorporation of renewable energies into the Spanish electricity market has affected the planning and operation of the system by and large. In particular, the Spanish system operator has created an operation center devoted to deal with wind energy operation. Since wind resources are highly variable in intensity and availability this has brought several implications to the operation of the system regarding security and market prices. To cope with this, fast generating units that can modulate this variability have been deployed to be available as reserves. Reserves needed in case of a high penetration wind power are determined and scheduled in terms of size and deployment time. In long-term planning, reserve requirements should also be considered as they affect the availability of the plants. The main issue is to achieve system reliability for different degrees of renewable penetration in Spain. The intermittency and lack of availability of renewable sources poses significant challenges for their integration into the Spanish electricity market and will be the subject of the talk.
