Case ENERCAL: Performance optimisation upgrade reduces operational costs

New Caledonian company, ENERCAL, wanted to optimise the operational cost and performance of their power plant. The solution was a Wärtsilä 46 Performance optimisation, consisting of engine tuning by means of a camshaft modification to Miller timing and an upgrade to ABB-TPL76C turbochargers. Two years of operation has established a 5g/kWh improvement for each engine, which enabled savings of about $400,000 in 2016.


Before the performance optimisation, the specific consumption of the power plant was about 218g/kWh with a utilisation rate of 52%, totalling the average annual consumption of fuel to about 55,000tons/year. In 2014, the price of the fuel amounted to approximately 73% of the global plant operational costs.

– The management of ENERCAL wanted to optimise the operational costs of the plant and decided in favour of a Wärtsilä 46 Performance optimisation, consisting of engine tuning by means of a unique camshaft modification to Miller timing and an upgrade to ABB-TPL76C turbochargers on two engines in September 2014, says Mr. Theodore.

Installation and commissioning took place during a scheduled major engine overhaul, which minimised the overall downtime. Performance tests were carried out before and after the modification.

– The two efficient Wärtsilä teams were well organised and were fully supported by Wärtsilä managers, which – to a great extent – helped to make the project a full success. The upgrade went as planned and the minor challenges only concerned the different pieces of equipment that needed to be changed for the upgrade, says Mr. Theodore.


According to Mr. Theodore, the results of the performance optimisation have been very clear and rewarding. Both the performance due to the overhaul of the engine and the performance due to the upgrade of the turbochargers were separated. Wärtsilä’s performance warranty stated a SFOC saving of 4g/kWh. However, the performance tests managed to record savings of more than 8g/kWh. These high savings results were partly due to the engine overhaul.

– After two years of operation, and comparing to the two unmodified engines, we have been able to establish a 5g/kWh improvement for each engine, which exceeds the promised saving. So, the performance improvement due to this upgrade of the power plant is real, says a satisfied Mr. Theodore. What does this performance improvement mean for ENERCAL as a company?

– In 2016, our company saved about $400,000. We could have had even greater savings if the modified engine had been in baseload operation, says Mr. Theodore. Now a couple of years after the performance improvement, ENERCAL continues to enjoy the benefits of the upgrade and Wärtsilä’s services. Mr. Theodore also appreciates the high quality of assistance from Wärtsilä and says that it is one of the reasons why he wants to continue cooperation with Wärtsilä.

– Today, we are very satisfied with this modification in terms of fuel consumption. If you have a Wärtsilä power plant running in baseload mode, I recommend doing a performance optimisation upgrade. Even for us, operating the plant as a peak load plant, it is very beneficial and fuel prices will surely rise again during the coming years, concludes Mr. Theodore.


  • Maintaining the competitive edge.
  • Reducing the operating costs of the power plant through guaranteed lower fuel consumption.

    Limbe Power Plant - Cameroon

    Eneo Cameroon’s Limbe power plant could generate only about 40% of the installed total capacity of 80MW. Wärtsilä’s solution was a complete rehabilitation; a total overhaul of four Wärtsilä 18V46 engines and five alternators.
