The largest wind farm built by ACCIONA in India

Grid-connected in September, 2017, the 78-MW Bannur Wind Farm is the largest one built by ACCIONA in India so far. It is the fourth wind facility owned by the company, reaching 163.8 MW of operational capacity in the country.

Located in Bijapur district in the state of Karnataka (south-west India), Bannur has twenty-six AW125/3000 Nordex-Acciona Windpower wind turbines (rotor diameter 125 metres) mounted on 120-metre high concrete towers.


The new facility generates an estimated 242 gigawatt-hours (GWh) a year, equivalent to the consumption of over 224,000 Indian homes and avoiding the emission of 232,562 metric tons of CO2 to the atmosphere from coal-fired power stations. The energy generated is supplied to the utility Bangalore Electricity Supply Company (BESCOM), following the signing of a long-term power purchase agreement (PPA).

This project is the first directly developed and built by ACCIONA in the Indian market, highlighting its capacity to adapt to the specific conditions of the country. The construction of Bannur has created more than 600 direct jobs, contributing to local development in the eighth biggest state in the country in terms of population. The concrete towers on which the turbines will be mounted have been built close to the site in a purpose-built facility.

The turbine nacelles have mostly been assembled in the plant set up by Nordex-Acciona Windpower – a company partly owned by ACCIONA – in the city of Chennai (south-east India). This factory assembles the AW3000 wind turbine, a 3-MW machine in its class II and III versions, which are ideal for sites with the medium-to-low winds that prevail in India.

Social Impact Management

The project's area of influence was studied during the construction period. Information was obtained from 83 families, as well as from local authorities, regarding the basic needs situation. With this information, it was possible to plan a medium-term social action intervention in collaboration with a local social entity starting in 2017. The following actions from this initiative are noteworthy:

  • Regular participation by ACCIONA staff in meetings in the various communities which involved local and regional authorities, children, parents and volunteers.
  • Direct dialogue with members of the community that help to identify different needs.
  • Local media coverage of the company’s initiatives in the area. 2

Social action

Since 2017, a project has been underway in collaboration with Pratham, a NGO dedicated to improving the quality of education in India. Some highlights from 2019 include:

  • Continued support for the 1,394 children with whom ACCIONA worked the year before in order to continue accompanying them in their improvement and learning process.
  • Competitions to discourage school dropouts and encourage the involvement of parents in the educational process.
  • Weekly skills building sessions for public school teachers.

This initiative was chosen by the United Nations Global Compact as an example of good practices to be disseminated by networks on the 4th anniversary of the approval of the Sustainable Development Goals.
