MADRID, June 15 (Reuters) - Spain's Telefonica has approved a plan to start selling electricity to its big corporate clients as part of a combined package with telecommunications services, El Periodico reported on Sunday, citing sources close to the company.
By signing up to get electricity from Telefonica, companies will also be required to buy a package of technological solutions related to energy efficiency, the newspaper said.
Telefonica declined to comment.
