Neoenergia operates in the renewable energy sector through three fronts: wind, hydro and solar. Taking into account the assets in operation and under construction, the company has a total of 44 wind farms, 5 hydroelectric plants and 2 solar parks.
Renewables and hydro
The hydroelectric generators work in such a way that the resource captured in the rivers for the movement of the machines is fully returned to the system, maintaining quality and volume, controlling any possible impact on the environment. The company has initiatives to monitor fauna, flora, and erosive processes; recovery and restoration of springs and Permanent Preservation Areas (APP), and environmental education. It also carries out studies to monitor biodiversity in reforested areas and maintains careful supervision to prevent irregular occupation, deforestation, and overhunting and overfishing.
The plants operated and maintained by Neoenergia Operation and Maintenance (NOEM) have an Integrated Management System, implemented with the scope “Operation and Maintenance, including Asset Management of Electric Power Generation Enterprises”, to comply with the standards ISO- 9001:2015 Quality Management, ISO- 14001:2015 Environmental Management, ISO- 45001:2018 Occupational Safety and Health Management, and ISO-55001 Asset Management.

Renewables and wind power
Among the assets under construction, Neoenergia has the Oitis Neoenergia Wind Farm, a strategic project for the expansion of Neoenergia's renewable portfolio, which will reach 1.6 GW in its wind asset portfolio this year.
Wind farms operated by O&M Renewables have an Environmental Management System and Occupational Health and Safety Management System implemented and certified under the scope “Operation and Maintenance of Wind Farms”, complying with the standards ISO- 14001:2015 Environmental Management and OSHAS 18.001 Occupational Health and Safety Management.
The project is part of the Santa Luzia II transmission project. In addition, the infrastructure connecting the power plants will be shared with the Chafariz Wind Complex, and therefore, it will have operational synergy with other investments of the group.
The new solar plant has already had part of its energy sold on the free market, through a twelve-year contract, starting in 2022, with Claro under the PPA (Power Purchase Agreement) modality.
