| Central Piedra Buena S. A. (“CPB”) |
Central Piedra Buena is located in the port of Ingeniero White, close to the City of Bahía Blanca, province of Buenos Aires. CPB has 2 turbines of 310 MW each, totaling 620 MW which represent 2.3% of Argentina’s installed capacity. The boilers can be indistinctly fired with natural gas or fuel oil.
The supply of natural gas is made through a 22 km gas pipeline owned by CPB, which CPB also owns, operates and maintains, and which connects to the main gas pipeline system of Transportadora Gas del Sur. Furthermore, CPB has two tanks for the storage of fuel oil with a combined capacity of 60,000 m3. From 1997 to 2009, its average annual generation was 1.874 GWh, with the highest level of generation (3,312 GWh) reached in 2008 and the lowest level (189 GWh) recorded in 2002.
CPB’s revenues are mainly composed of energy and capacity sales. Total revenues for the twelve-month year ended December 31, 2009 were Ps.817 million, corresponding to a net generation of 2,391 GWh, 27.8% lower than in 2008. Such reduction is mainly explained by the plant’s lower dispatch during the last months of the year caused by an increase in the use of the hydroelectric generation system, and to a lesser extent, by an increase in maintenance works during 2009.
