Brazil to embark on site studies for new nuclear power plants

Brazil’s nuclear utility Eletronuclear and the Empresa de Pesquisa Energetica (EPE), part of the Ministry of Mines and Energy, have agreed a technical co-operation deal for identifying future nuclear build sites.

The two organizations will co-operate to develop preliminary studies for the selection of future nuclear sites. Brazil wants to establish four by 2030.

Led by EPE, the survey will primarily use public databases built up by various national geological and natural resource authorities.

Brazil currently has only one nuclear power plant, Angra, which features two operating reactors and another currently under construction.

In 2007, a National Energy Plan produced by EPE was adopted by the government, stipulating that four new nuclear sites should be found in the southeast, south and midwest of the country.

According to EPE, the states of Espirito Santo, Minas Gerais, Rio de Janeiro, Sao Paulo, Parana, Santa Catarina, Rio Grande do Sul, Goias and Mato Grosso do Sul would be part of the preliminary survey.

Mauricio Tolmasquim, the president of EPE, said the co-operation with Eletronuclear would be important to the study because of the nuclear operator’s expertise in the technology.

Siemens wins gas turbine order for Mississippi’s IGCC power plant

Mississippi Power Company, a subsidiary of Southern Company, has awarded Siemens Energy a contract to supply two SGT6-PAC 5000F gas turbine packages to its coal fired integrated gasification combined-cycle (IGCC) power plant.

Southern Company’s proprietary TRIG gasification technology is expected to contribute to the capturing of about 65 per cent of the 582 MWe Kemper County power plant’s carbon dioxide (CO2) emissions ” a reduction of around 3 million tonnes of CO2 per annum.

Siemens said that the Kember County plant is expected to go into operation in mid-2014.

USA’s largest ocean energy system produces grid-quality power from tidal currents

Ocean Renewable Power Company’s (ORPC) Beta Power System has successfully generated grid-compatible power from tidal currents at its Cobscook Bay site off the cost of Maine, USA.

The system’s core component, the proprietary turbine generator unit (TGU), has a maximum design capacity of 60 kW. The system is the biggest marine energy conversion device installed in US waters.

Spanish consortium to build 102 MW Honduras wind farm with 51 turbines

Gamesa and Iberdrola Ingenieria y Construccion have won a a joint turnkey contract to build the 102 MW Cerro de Hula wind farm in Honduras.

The wind farm’s owner is Mesoamerica Energy, a developer of renewable energy projects in Central America and neighbouring countries via its local subsidiary, Energia Eolica de Honduras.

The project has a 20-year power purchase agreement (PPA) contract with the state-owned power utility Empresa Nacional de Energia Electrica, and will be financed with funds from the US Export-Import Bank and the Central American Bank for Economic Integration.

The wind farm will have 51 Gamesa G87 2 MW wind turbines, and is scheduled to be completed within an 18-month period. Gamesa’s scope covers the manufacture, supply, transport and erection of the wind turbines, including supervision and start-up of the turbines.

Iberdrola Ingenieria will help design and construct the wind turbine foundations, access roads and erection platforms, as well as the site’s O&M building.

Elecnor, Sener secure Mexican hybrid combined-cycle deal

A consortium led by Elecnor and Sener has landed a contract to design, build and put into operation Agua Prieta II, a 400 MW combined-cycle plant, to be located in the northeast region of Sonora in Mexico.

The contract, which is worth $252m, will be carried out under the Mexican government’s public works financing model.

As part of the deal, the consortium will also be responsible for an adjacent 12 MW solar field, creating an integrated solar combined-cycle plant.

Uruguay plans $1.7bn investment to boost output

UTE, Uruguay’s state power company, has announced plans to invest $1.7bn over the next five years as part of an effort to meet the country’s rising electricity demand.

The country’s demand for electricity is expected to grow by 6.1 per cent this year, and by an average of just over 3 per cent in the coming years. UTE is already working on a $320m grid interconnection project with Brazil, which is slated for completion in 2012, according to BNamericas.
