Spanish utility Endesa has made its first trade of voluntary emission reduction credits, equivalent to 20,000 tons of carbon dioxide avoided by repowering of the 80.2-MW Callahuanca hydroelectric project in Peru.
Endesa’s Peruvian subsidiary, Empresa de Generacion Electrica de Lima (Edegel), carried out repowering of the four-unit 72.7-MW project in 2007. By replacing 67-year-old turbine-generators and transformers of three 12.6-MW generating units, the utility increased project capacity by 7.5 MW.
Callahuanca, on the Santa Eulalia River in Peru’s Lima Province, is one of seven hydropower projects operated by Edegel totaling more than 750 MW. (HNN 5/30/07)
The transaction of voluntary emissions reductions (VERs) was brokered by Spanish energy broker Wind 2 Market. VERs are emissions reductions not contemplated under the United Nations’ Clean Development Mechanism for carbon reduction. VER buyers generally are companies and individuals that use them to voluntarily offset emissions from buildings, travel, vehicle fleets, and other activities not covered by the mandatory Kyoto Protocol emissions markets.
