The Santo Antonio do Jarí Hydroelectric Power Plant, currently under construction, has been conceived as part of the Brazilian National Interconnected energy System and is designed to achieve 373 MW of installed capacity and reduce environmental impacts by reducing CO2 emissions drastically. The Jarí hydroelectric power plant is being developed in the States of Pará and Amapá in the Jarí River, considered the main tributary of the Amazonian basin north watershed. The hydroelectric dam consists of 3 Francis-type generating units with an installed capacity of 370 MW and one Bulb-type generating unit with an installed capacity of 3.4 MW. Once fully operational, it will allow for the reduction of fossil fuel dependent thermal energy, currently representing 70% of the regional Matrix, to 25.9% by 2016. The connection to the national network will be done by means of a 20 km long 230 KV High Tension Line, also part of the project to connect Jarí Hydroelectric dam with the Laranjal do Jarí Substation, and with the High tension Lines of the System Tucurui-Macapá-Manaus. This connectivity will enable the energy produced at Jari hydroelectric dam to be used at the cellulose and kaolin industrial complex in Port Munguba, in large regional centers like Macapá, and in other regions of the country.

EDP Energias do Brasil is developing the US $360 million power plant planned to begin operations in 2015. Jarí Hydroelectric Dam will contribute to reduce carbon emissions and to increase the reliability of energy supply in the region. Compensation measures have been properly established within the environmental licenses and in the program for the recovery of degraded areas to offset the 1,706 hectares of native forest habitat suppressed for the creation of the new lake reservoir that has reduced local biodiversity and destructed habitats.
