Greenhouse Gases

Sulphur hexafluoride (SF6) is the only greenhouse gas that is present in the installations of Iberdrola Distribución Eléctrica. This gas provides excellent electrical insulation and is used widely by manufacturers of switching equipment (switches, switchgear cubicles, etc.).

A Voluntary Agreement has been signed between the Ministry of the Environment, the manufacturers and suppliers of electrical equipment that uses sulphur hexafluoride, and electricity transport and distribution companies, including Iberdrola Distribución Eléctrica, for limiting the emissions of sulphur hexafluoride.

This Voluntary Agreement encompasses a number of actions, including:

  • Standardising the inventory of equipment installed in the national grids.
  • Providing training to the staff responsible for handling equipment containing sulphur hexafluoride and certifying their qualification to carry out this task.
