Zhukov spoke Wednesday at a meeting with the leaders of the Spanish Confederation of Entrepreneurs.
Zhukov said the list of Spanish companies interested in energy cooperation with Russia included Repsol, Spain's largest private oil and gas producing and refining corporation, and Iberdrola electric power operator.
The materials prepared for Zhukov's visit to Spain say that Repsol is continuing negotiations on a possible joint venture with Russian company Tambeineftegaz to develop the Tambeisky field on Yamal in Russia's Arctic, and with U.S. Anadarco to implement a project for liquefied natural gas production and transportation.
Zhukov said Russia and Spain also had good prospects for cooperation in alternative energy projects, adding that Iberdrola had already signed a contract to create a wind-turbine farm in the Krasnodar Territory in southern Russia.
Zhukov also said Spanish company Tecnicas Reunidas had started the modernization of the Khabarovsk refinery in Russia's Far East under a $800-million contract.
