Bulk purchasing of fuel over multi-year timeframes and combining volumes with other purchasers to achieve economies of scale. Prices for fuel are comprised of two components - fuel itself and the transportation cost to get it to site. The fuel itself is generally pegged to the world price so there is not much alternative but to pay the price on delivery, however competitive forces can come into play in the transportation component.

Installation of fuel-efficient engines. The newer generation of diesel generators supplied by manufacturers are generally more fuel-efficient than the earlier models. This is due to the use of electronics and the evolution of engine design.

Installation of individual genset fuel monitoring. This will enable undertaking genset maintenance based on actual fuel consumption rather than engine-hours. This should lengthen overhaul intervals.

Installation of power plant control equipment to match engines to loads and to operate running engines as close to peak efficiency as possible. The Corporation will continue to, install such equipment (called Programmable Logic Controllers or PLC's). These devices have brought significant improvement in fuel efficiencies in plants in which they have been installed.

Installation of energy efficient auxiliary equipment in powerhouses such as lighting and Variable-Frequency Drives (VFD) for radiator fans.

Utilization of jacket water heat from operating engines to heat plant spaces and keep standby gensets warm.
