Energy is a critical input to our operations, and our challenge in Latin America and the Caribbean is to secure sources of energy while simultaneously reducing our impacts on the environment and society.


In 2013, our operations had their lowest energy intensity since 2009, with a 1.3% reduction over the prior year. Energy-efficiency efforts and idled capacity were the primary reasons for the decline.


Estreito Hydroelectric Power Plant

Estreito Hydroelectric Power Plant

In the majority of our operations in Brazil, we primarily consume hydroelectric power. We are a partner in the Estreito Hydroelectric Power Plant, which became fully operational in the first quarter of 2013. We have established a social agreement with stakeholders and government authorities at three levels to promote the sustainable development of the 12 municipalities located near the Estreito facility. Along with our partners and Brazil’s National Bank for Economic and Social Development, we have developed a fund to invest in social projects for these municipalities. Through the end of 2013, approximately US$30 million was invested in 112 social projects in five major areas: social development, education, health, sanitation, and economic development.


We are also a partner in three other operating hydroelectric power plants in Brazil—Barra Grande, Machadinho, and Serra do Facão. The Pai Querê Hydroelectric Power Plant, in which we are also a partner, is in the licensing stage. Another plant that was in the licensing stage—Santa Isabel—was returned to the government in 2013.


In 2013, we revised our energy strategy in Jamaica to focus on evaporator operation, boiler operation, and steam consumption. As a result, those operations secured an 8% reduction in energy intensity over 2012.


In Suriname, we own and operate a hydroelectric power plant that produces electricity for our operations in that country and also provides 80 million kilowatt hours of electricity to the government of Suriname. In 2013, these operations had a 3% increase in energy intensity due to production curtailments that decreased energy efficiency.
