Enercal

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.
