PT Kertas Leces (Persero) is one that specializes in state-owned pulp and paper industry which produces various kinds of paper, such as writing printing paper, newsprint, tissue paper and paper industry, production capacity of 600 tons / day with the main raw material bagasse, waste paper (OCC & ONP), and wood pulp.

PTKL energy required to meet the production process from his own generation, which consists of 5 (five) Power Boilers, 2 (two) Chemical Recovery Boiler and 3 (three) Steam Turbine.

In the vessel energy efficiency, PTKL plan to build coal boilers, which is fuel substitution efforts of natural gas to coal, the basic consideration that since March 2005 the supply of natural gas tend to experience a "shortage", but that price tends to increase (from U.S. $ 2.9 / MMBTU in 2003 to U.S. $ 5.2 / MMBTU in 2007).

With this project, expected PTKL can save energy costs of U.S. $ 94 per ton of paper (with lower energy cost component of 18.51% to 11.29%)
The source of financing in the implementation of the project was obtained from the Boiler Budget Year 2007 through the State Capital Investment (PMN) which was budgeted in the 2007 Budget year.

Coal Boiler planned consisting of 2 (two) unit, will be built with the capacity of each boiler of 120 tons / hour, and steam pressure of 44 bar with a temperature of 4400C. Old equipment was to be used for permanent standby unit and can be used to combine with the new units to meet certain conditions (peak demand).

And on June 14th, 2007 in Building Cafeteria PT Kertas Leces (Persero) has been implemented Construction Aanwijzing Coal Boilers, followed by 7 companies considered to have passed the selection stage of prequalification. This is carried out based on Presidential Decree. 80 In 2003, along with Rule change is.
