As part of our commitment to Biodiversity, Iberdrola Distribución Eléctrica conducts a variety of activities at the installations that enable us to reduce the impact of electricity and gas distribution on the fauna, flora and soil.
See more information: Iberdrola Biodiversity Policy [PDF].
Based on the firm commitment of Iberdrola Distribución Eléctrica to minimise the impact of the installations on the fauna, environmental improvements are being introduced into the installations.
The presence of overhead power lines in some geographical areas enables white storks to build their nests on pylons, a safe point which is not accessible to their natural predators.
However, this type of nesting poses a risk of electrocution to the storks. For this reason, a pilot project is being conducted aimed at changing the white stork's habits. This involves moving the nests once the chicks have been born.
During the breeding season, the chicks are moved to artificial nests especially designed for storks. Technicians from the public administration participate in these moves and supervise their proper execution. Monitoring field work has confirmed that both the chicks moved and their parents take up residence in the artificial nests.
You can see an example of an actual stork nest move (below).
To prevent birds from colliding with the power lines, elements like the one shown in the image are placed.
To reduce any possible disturbance caused by electrical installations coexisting with flora, a variety of actions are taken, including:
Some electrical installation equipment (transformers, switches, other switching elements, etc.) requires the use of dielectric oil as an insulating element.
To prevent spills of this type of oil, we are carrying out several preventive actions.
As a preventative measure against possible minor spills, all the maintenance units have the resources and specific training needed to avert this type of spills:
In electric power substations with equipment that uses greater quantities of oil, containment deposits are built to protect against possible spills. In the event of a leak in the transformer, it is channelled and collected in the containment deposit.
A rapid response brigade is also available, made up of staff who are expert in environmental emergencies and capable of solving them in the shortest period of time.
