Etisalat Egypt aims to complete and operate 70 new solar powered cellular phone towers by the end of this year, Chief Corporate Affairs Officer Khaled Higazi said, according to Al Mal. The company currently operates 100 solar-operated towers which “cost six times more to develop than regular ones but are part of Etisalat’s strategy to increase its use of clean energy.” No details were mentioned about the investment cost or source of financing, but Etisalat had announced earlier this week a decision to increase investment in network infrastructure upgrades to EGP 3.5 bn this year.
