Traditionally EGAT's approach has been to respond to projected increases in demand by planning new large-scale power plants. But this is not the only way of doing things. International best practice is to consider electricity planning as holistically as possible, as a problem in delivering energy services, not just delivering kilowatt hours of energy. Thus, it makes more sense to consider all least cost measures that will provide the same service, comfort and convenience, even if this means not having to sell more electricity. Taking this Integrated Resource Planning (IRP) frame substantially broadens options (Swisher, 1997; D’Sa, 2005). The broader menu of choices include investments to acquire energy savings, clean renewable energy generation, cogeneration, as well as plant life extension, repowering, and brownfield siting of conventional power plants.
