The Alhorines Valley (Spanish: Valle de los Alhorines) is a valley and a major grain producing area of the provinces of Albacete, Alicante and Valencia in Spain. Historically it was long disputed between the towns of Caudete and Villena. A large solar thermal power plant has recently been built in the valley. The lesser kestrel was re-introduced in 1997. Conservation measures have been taken to minimize impact of the power plant on the birds.
