This paper reports the results of small scale wooden biomass Co-Generation System (we call it WBCGS) that had been introduced into S Prefecture T city in 2007. WBCGS uses LPG to start the gas engine and produce heat and electricity sent to the demand side. The fuel of the engine is a wood chip. The raw material of the wood chip is local thinned wood, forest reminder material, and mill ends. As the result of the yearly total efficiency was 62.9%, the power generation efficiency was 10.6%, and thermal efficiency was 52.3%. After WBCGS had been introduced, 101 t-CO 2 a year was reduced 88.6% has been reduced compared with conventional system.
