The client's demand was a significant decrease in energy cost without heavy burdens of investment and management.

It is a project with a structure of a corporation established with an external shareholder who supplied steam and the company entering into a subcontract agreement on construction and operation of the corporation.
Facility Establishment: established the facility of producing steam by using solid fuel such as a furnace, boiler, prevention facility, water supply/pipe, electricity/instrumentation, etc.
Operation Service: by operating the established facilities, 4.5 tons worth of steam were supplied during 10 years.

42% compared to production cost and 28% compared to actual fuel cost were saved and 5.2 billion won could be reduced per year by considering only the fossil fuel purchase.
Also guaranteed higher ROI even for times of sharp oil price decrease by linking the supply price to the oil price while setting the lower price limit.
