Since 2012, ACCIONA Producciones y Diseño has been developing ‘carbon neutral’ events for its clients and offsetting the CO2 emissions associated with them through the Tuppadahalli Wind Energy project in Karnataka (India).


Wind is an inexhaustible force that provides a clean and renewable source of energy. The renewable sources are the necessary base for sustainable development The Tuppadahalli Wind Energy project consists of a 56.10 MW wind farm with 34 turbines of 1,65 MW which prevents the emission of 128.809t CO2 a year going into the atmosphere. It is registered before the United Nations as CDM (Clean Development Mechanism) under the Voluntary Carbon Standard (VCS), receiving 54.000 VERs for the generation of clean energy.

Contribution to sustainable development

The project clearly contributes to sustainable development, following the guidelines to evaluate the contribution to sustainable development in CDM projects. These guidelines stipulate that the project must ensure social, environmental, economic and technological well-being to the local community.

Social well-being and employment
  • The activities of the project result in direct and indirect benefits to the region by generating local employment, besides creating better conditions for the development of economic activities.
  • The purchase of the turbines was made within the country itself, thereby generating employment from the construction of the turbines which benefits the country receiving the investment. The construction was developed by an Indian company
  • Maintenance of the wind farm is carried out by ACCIONA’s Indian team, all locally employed.
  • The energy generated supplies the network of electricity which benefits the local communities who see the improvement in their electrical supply. In this case, the supply of electricity is renewable which helps to reach the objective of energy security for present and future generations.

Environmental well-being
  • Energy from wind farms is one of the least contaminating and most sustainable forms of generating electricity since, among other things, it does not produce emissions (CO2, SOx, Nox) nor particles.
  • In the case of India, the energy-mix is heavily based on carbon, so the emissions from generating energy are high: the production of each MWh creates the emission of 0,9445t CO2.
  • The Tuppadahalli Wind Energy project prevents the emission of 128.809t CO2/year.
  • Following ACCIONA Energy’s internal regulations, a previous study was carried out on environmental impact, even though this is not required by the country’s legislation.
  • Cabling was laid underground, and the transformers were covered, which is usually not done for projects carried out in India.
  • The topography was respected as best as possible, which meant an increase in investment.
  • Special care was taken in restoring the vegetation of the surroundings.

Technological well-being
  • The project contributes to the transference of technology to the country. The fact the turbines are acquired in the country itself results today in the project acting as a catalyst and accelerator in the development of the sectors of wind farm and renewable energy in India.
  • The turbines used are of advanced technology and from a recognized supplier of international prestige (Vestas).
