The first Siemens gas turbines for the expansion of three power plants in Bolivia have started their way to South America. In May 2016, Siemens signed the corresponding agreement to increase the power generating capacity of the country by more than one gigawatt. The two machines, manufactured at Siemens Industrial Turbomachinery in Finspang, were loaded onto a heavy load carrier in the harbor of Norrköping, Sweden. The cargo with more than 170 tons will travel first up to 14,000 kilometers on sea route to the harbor of Arica in Chile. From there the modules will be transported to Bolivia traveling additional 1,800 kilometers in partially rough terrain. In total, power plant equipment from three continents will be delivered to Bolivia and up to 400 heavy load transports will cross the Andes to bring equipment to the three power plant construction sites.
Two industrial gas turbines started their journey over the Atlantic Ocean and through the Panama Canal. After landing at the Arica port in Chile, the cargo will be loaded on a truck to travel the remaining 1,800 kilometers to the construction site at Termoeléctrica del Sur on overland route crossing the Andes at a height of 4680 meters. The slightly developed road network, rough terrain and extreme weather conditions are the main challenges for the overland transports. The two gas turbines will be installed to drive the electrical generators and produce steam to drive the steam turbine and thus increasing the efficiency of the power plant to more than 50 percent.
Siemens will supply 14 industrial gas turbines, eleven steam turbines and further power plant equipment to expand the Termoeléctrica del Sur, Termoeléctrica de Warnes and Termoeléctrica Entre Rios plants for combined cycle operation. With the expansion projects, Siemens and its Spanish consortium partner TSK are adding more than one gigawatt to the Bolivian power grid. The projects will increase the installed power generating capacity of Bolivia´s National Interconnected System by 66 percent, provide a reliable energy supply for the local population and lay the foundation for a possible electricity export.
