MAN Diesel & Turbo has completed installation of eight type 18V48/60 engines in the Planta MAN 140 power plant in Los Brasiles, Nicaragua.
The plant, which replaces older diesel power plants and balances electrical generation fluctuations, will now be operated by ALBA Generacion S.A.
Nicaragua has ambitious plans with regard to power generation. It is aiming to produce 90% of electrical power from renewable sources by 2020. Renewable sources, primarily wind power and hydropower, already account for 57% of the country's electricity demand.
"Engine power plants are ideal as a back-up for renewable energies," explains Thorsten Dradrach, Head of Sales for Power Plants on the American continent at MAN Diesel & Turbo. "Not only can the engines be started up and reach full load in 3-5 minutes, they also operate efficiently at partial load. In the event of low wind levels or even no wind at all, our MAN48/60 engines generate energy reliably and in a highly flexible manner in order to compensate for fluctuations in the power network."
Transporting the engines 156 kilometers from the port of Corinto to Los Brasiles was a highly logistical challenge. At temperatures of up to 40 °C and under increased volcanic activity, each of the eight 320-ton engines had to cross more than 60 bridges, many of which first had to be bridged with fly-over ramps.
