SUSTAINABLE INITIATIVES

Carbon Credit

Constant concern for the environment has led countries part of the UN to sign the Kyoto Protocol, an agreement that stipulates goals for reducing greenhouse gas emissions and created the Clean Development Mechanism (CDM), aimed at the certified reduction of said emissions.

Another certificate that may generate carbon credits is the Renewable Energy Certificate issue by the I-REC (International REC Standard), a global system that permits the trade of renewable energy certificates.

Atiaia Energia has earned these certificates and has already sold over 300,000 tonnes of carbon credits generated through the energy produced at the Pedras and Garganta da Jararaca SHPs.

Renewable Energy Certificate

Atiaia Energia is part of a select group of controlled companies that feature enterprises certified as part of the REC – Renewable Energy Certificate Program, which allows it to issue RECs (Renewable Energy Certificates).

The Porto das Pedras SHP earned Renewable Energy Certification through a joint initiative with the ABEEólica (Brazilian Wind Energy Association) and Abragel (Brazilian Clean Energy Association) which certifies renewable energy generation and consumption enterprises that, besides fulfilling pertinent legal requirements, also develop voluntary social and environmental programs, which ratify their commitment to sustainability.

Spawning Channels

Atiaia Energia is a pioneer in the Mid-West region by adopting a Fish Spawning Channel (FSC) system at SHPs, allowing schools of fish to migrate upstream during spawning season.

The Paranatinga II SHP features the system, which is similar to steps built to allow fish to bypass the barriers and leap a series of relatively low obstacles to access the water on the other side. Equipped with cameras and a compartment with a glass wall, the schools of fish can be monitored 24 hours a day.

Study of Regional Fish Species

Atiaia has undertaken several studies to observe the reproductive processes of the varying fish species that serve as a food source to riparian communities, the villages of the Xavante people and tribes in the Xingu Indigenous Park, which all surround the Paranatinga II SHP. The inventory of fish species in the Culuene River is one of the most complete undertaken in a Brazilian river. An effort was coordinated by the University of São Paulo’s Zoology Museum, with the participation of universities in Mato Grosso and Minas Gerais. Over 250 species were cataloged, 20 of which were as yet unknown.

Ancestral Memory of Indigenous Peoples

In 2008, the Rodrigo Melo Franco de Andrade Award included the project that, with the support of Paranatinga II SHP, led to two Indigenous areas in Alto Xingu, Mato Grosso, to be declared permanent reserves. The sacred grounds of the Sagihengu and Kamukuwaká peoples was the stage of the first Kuarup, a ritual conducted by the Xingu tribes.

This award, granted by the IPHAN (National Historic and Artistic Heritage Institute) is one of the most important in the area of cultural and historic heritage protection in Brazil.

Protection of Archeological Sites

A unique program underway at the Porto das Pedras SHP at a rock outcrop called Alto Sucuriú, one of the oldest archeological sites in Brazil has been identified. To protect the area, which is filled with rock paintings, archeological monitoring has been implemented, with specific excavation areas, a heritage education program, the production of an informative film and printed material. The site has been isolated and sheltered, with protected native flora and now considered an area of permanent preservation at the SHP.

Run-of-the-river System

All of the plants run by Atiaia operate on a run-of-the-river system, whereby the level of water in the reservoir is regulated automatically, remaining constant. This way, the water flow in the river isn’t altered because when it reaches the dam wall, it passes downstream.
