Fuels Wärtsilä uses various fuels in its manufacturing, R&D and service operations. Major part of fuel consumption is related to engine testing. Other types of usage includes heating and transportation. Electricity Wärtsilä uses electricity in its manufacturing operations – for example, in machining components – and in service workshops and offices. Both the electrical and the heat energy generated during engine test runs can be utilised. Wärtsilä’s aim is to use the electrical energy for its own purposes while also selling part of this electrical energy to a local power company. Due to the nature of engine test runs, the production of electricity and the company’s electricity demand are not equivalent; this allows the surplus energy to be sold to a local power company.
Heat Heating for factories and offices accounts for most of Wärtsilä’s consumption of heat energy. In several factories the heat generated in engine test runs is used for heating. Some factories and offices are connected to a local district heating network, some have their own heating plant, and some use electricity for heating.
