Retrofitted turbocharger reduces operating costs for power plant

The Central Electricity Board (CEB) of Mauritius improved the performance as well as reduced the operating costs of their power plant by having a turbocharger retrofit. “The result was very satisfying: improved performance, less operating costs due to lower fuel consumption and reduced emissions,” says Mr. Manoj Kumar Jahajeeah, Officer-in-Charge of the Production Department at the Central Electricity Board, Mauritius.

The Pointe Monnier power station is located on Rodrigues Island, about 600 km northeast of the Mauritius main island. The Wärtsilä 6L32 engine, with an output of 2.5 MW, is the primary baseload generating set because of its generating capacity, generally producing more than 30% of the total monthly electricity generation on the island.
