The total <strong>in</strong>vestment cost <strong>of</strong> the <strong>cogeneration</strong> plant amounted to US$ 523,000 <strong>and</strong> the annual<br />
cost sav<strong>in</strong>gs expected from the self-generated electricity is estimated as US$ 243,700. The<br />
factory expects to recover the <strong>in</strong>vestment with<strong>in</strong> 3 years after the commission<strong>in</strong>g <strong>of</strong> the<br />
<strong>cogeneration</strong> plant.<br />
Encouraged by the results, the company plans to achieve a ‘zero waste’ level <strong>in</strong> the factory.<br />
There is a plan to fully exploit the excess energy by generat<strong>in</strong>g up to 2.5 MW <strong>of</strong> electricity <strong>and</strong><br />
<strong>in</strong>tegrat<strong>in</strong>g the operation <strong>of</strong> downstream activities such as the kernel crush<strong>in</strong>g plant <strong>and</strong><br />
medium density fibreboard project.<br />

The Thai Government policy <strong>of</strong> <strong>in</strong>itiat<strong>in</strong>g <strong>and</strong> decentraliz<strong>in</strong>g economic development has led to<br />
the successful creation <strong>of</strong> several <strong>in</strong>dustrial complexes away from the capital. These<br />
<strong>in</strong>dustrial complexes require considerable amount <strong>of</strong> reliable power <strong>and</strong> process steam. Many<br />
<strong>in</strong>dustries <strong>in</strong>side these complexes are excellent customers <strong>of</strong> large-sized <strong>cogeneration</strong><br />
plants. One such 300 MW gas-fired <strong>cogeneration</strong> power plant was launched <strong>in</strong> Map Ta Phut<br />
Industrial Estate as early as <strong>in</strong> 1994. 5<br />
