When a fuel is burnt in order to produce electricity, heat is produced. But many buildings that use electricity also use heat. If the electricity is generated in the building, the inevitable heat generation need not be wasted, but can be used for comfort heating, water heating, steam raising, product drying, and cooking, etc. Cogeneration requires an investment in an engine and electrical controls, etc. Again, the most obvious solution may not be the only, or indeed the best.
Many diesel generators lose their value as their operating time approaches their life expectancy.
Of course, some of the capital savings would have to be invested in a thorough survey of the diesel generator's equipment. These will provide power in some circumstances which would otherwise lead a power outage. Carefully consider whether a second feeder will meet your requirements. Some electricity distribution companies offer no-break and standby power supplies for an annual fee related to your maximum demand.
