At PowerSeraya, the primary and direct sources of energy used for our business are fuel oil and natural gas which are bought on the open market. There was a reduction in fuel oil consumption of about 16.5% between FY06/07 and FY07/08, or 255,355 tonnes in absolute terms. Natural gas consumption for FY07/08 was about 34,457 BBTU (Billion British Thermal Units), which is about the same as FY06/07.

Note Fuel oil refers primarily to heavy fuel oil and intermediate fuel oils. However, the figures include a very small proportion of diesel oil which is used as contingency and for peaking purposes.

In PowerSeraya's context, our direct and primary source of energy used for our business (i.e. electricity consumption) is from the fuel oil and natural gas that we use/consume (this we measure in Tonnes or BBTU rather than Joules).
