Our objective: preserve and protect

In the Iberdrola group, we manage aspects related to biodiversity through four priority lines of action: protect, study and preserve, raise awareness and inform, and collaborate with stakeholders.

Aspects relating to biodiversity are managed following the basic principles of action defined in the Biodiversity Policy:

  • To protect biodiversity, applying a preventive approach (avoid and minimise impacts) in decision-making at the implementation, operation and dismantling stages of infrastructure projects.
  • Biodiversity understanding and preservation biodiversity, through the application of positive conservation management and site research, with the aim of achieving a net balance in relation to the environment.
  • A commitment to raise awareness about the importance of biodiversity and communicate internally and externally about the impact of our biodiversity conservation activities and actions.
  • Collaborate with Stakeholders, considering their needs and expectations in matters of biodiversity in order to integrate them into action plans and collaborate on research projects.

These basic action principles are developed in priority lines of action and are put into practice with specific activities classified in the following categories:

  • To avoid, minimise and remedy the impacts of our activities on nature: this includes preventive, palliative and compensatory actions.
  • Understanding the environment and assessing the impact of our activities throughout their entire life-cycle: this includes pre-construction studies and monitoring during and after construction, as well as specific studies during operation.
  • Awareness-raising and communication: this includes internal and external training and education, awards, publications, cooperation, sponsoring and financing activities, etc.

Iberdrola has been working for many years on biodiversity programs and plans on an ongoing basis, following the above lines of action. In June 2017, and as an example of this commitment to nature conservation, Iberdrola received an award from the General Management for the Environment of the Extremadura Regional Council for its conservation work in the Monfragüe National Park.

  • United Kingdom

    ScottishPower Renewables (SPR), at the wind farms in the United Kingdom, uses the Biodiversity Conservation Strategy as a reference for both the development of new wind projects as well as existing ones, with a special concern for improving the environment (flora and fauna) of the facilities, and establishes Habitat Management Plans (HMPs) as a tool for each installation. This allows SPR to compensate or mitigate for any habitat lost through the construction of a site, and often provides additional enhancement. This requires SPR to work together with statutory bodies, including Scottish Natural Heritage, the Royal Society for the Protection of Birds and the Forestry Commission, to ensure that management complements national biodiversity aims and follows best conservation practice. These HMPs have different aims and targets depending on the characteristics and types of habitat, which is why a specific plan is produced for each affected area. Biodiversity Action Plans (BAPs) continue to be developed at each facility, except at the Daldowie sludge drying plant. These plans define the goals for maintaining and improving natural habitats on their lands as well as an implementation schedule. Activities and goals include the following: providing natural and artificial refuges for various types of birds and bats, and encouraging the availability of food for them (by increasing the diversity of the flora, etc.); encouraging the preservation of habitats for the development of individual species of flora and fauna; improving the management of arboreal and woodland species; developing aquatic habitats; controlling plagues and animal diseases; limiting the use of herbicides, and establishing good practices for their use; planning work activities so as to minimize the impact during the breeding season; raising employee awareness; and facilitating fish travel (by means of fish ladders, the installation of counters to track the specimens that use them, etc.).

    More information at the section ScottishPower Biodiversity Action Plans, which includes records of downloadable information regarding biodiversity and its management at each generation plant.

    Generally, the centres work in close cooperation with official bodies, NGOs and volunteer groups to promote BAP goals and carry out specific projects to manage potential impacts on protected sites, improve awareness of conditions at protected sites, and improve the conditions of species included in the UK Biodiversity Action Plan (UK BAP).

    The company's network organization in the United Kingdom has a Biodiversity Procedure that affects large projects, including the construction of overhead lines and substations. The procedure covers projects from the planning and consultation phase to the development of specific plans to protect biodiversity and habitats during the construction phase.

    In addition the following specific actions are worthy of note:

    Gas storage plant Implementation of Biodiversity Action Plans (BAPs) at each facility e.g. creating nesting areas, sanctuaries and food for native species. Providing habitat for the populations of nesting birds. Communication, training and monitoring of ecological activity.(more information is available at Recover and promote regeneration of natural habitats and of the flora and fauna characteristic of facilities' environments.
    Wind farms 62 actions in 20 areas included in the Habitat management plan, basically monitoring of birds and of reforested areas and 39 management actions, such as restoration, elimination of invasive species, vegetation management through grazing, etc. To recover and improve land affected by construction activities.

    To reduce the impact on wildlife.
    Foundation projects Sussex Wildlife trust in the environmental and educational project "Wild Side of the Track". Sustainable improvements to habitats.
  • United States

    In the regions where Avangrid subsidiaries operate, areas with high biological diversity (whether protected or not) are avoided in new overhead power line projects. Moreover, Iberdrola is working with the Audubon Society and the New York Department of Environmental Conservation in order to provide nesting areas away from power lines, e.g. for the Osprey.

    The Renewables Business continues to implement the Avian and Bat Protection Program (ABPP), which is aligned with the new biodiversity guidelines and recommendations for wind energy facilities from the US Fish and Wildlife Service, an organisation with which it actively cooperates.

    Also, extensive studies of birds and bats at the wind farms has been done, and scientific research work supported. Every year, activities for the conservation of biodiversity related directly or indirectly to wind farms are developed, as required by the laws and regulations of the United States. The actions carried out include studies on the effects on wildlife of wind power plants, always validated by expert biologists, studies on birds and bats in wind farms environments, in which NGOs are involved, and monthly monitoring of indicators associated with biodiversity.

    In addition, the following specific actions are worthy of note:

    Power lines Water treatments in collaboration with land owners in two river basins, treating runoff from impermeable areas in the basins prior to its entry into the river. Improve water quality and the aquatic and riverbank habitat.
    Adaptation of power lines. To minimise impact on the osprey in its nesting and reproduction processes.
    Collaboration in obtaining wetlands with the organisation Ducks Unlimited through financial collaboration, stemming from the Auburn Transmission Project. To improve the quality of the aquatic habitat and help the species.
    Wind farms Recover natural habitats and foster their regeneration, avoid the displacement of indigenous species, monitor species, raise awareness, and train local communities. In 2018, 20 monitoring and mitigating activities were undertaken. Reduce impact on flora.
    Raise social awareness of the area's rich biodiversity.
