Small Engines Large Engines Aftermarket Services Military Engines Space Propulsion Power Systems Mobile Power and Distributed Generation Defined • DG resources are smaller scale power generation equipment (up to 50 MW) located close to where the power is used; MP power generation is equipment designed to be • conveniently movable to suit load shift requirements; • DG and MP equipment include: micro turbines, combustion turbines, reciprocating engines, Fuel Cells, etc; • DG and MP equipment is used to complement central power systems, provide incremental capacity in a short time, and avoid/reduce the cost of T&D system upgrades.

Mobile Power and DG Applications • Supporting the grid in situations where new load requirements cannot be met without costly T&D upgrades; • Meeting demand for power in emergency situations or in areas not served by the grid; • Avoiding voltage sags, voltage spikes and noise which can cause problems for sensitive industrial equipment; • Reducing overall load by using highly efficient generators in lieu of grid supplied power; Mobile Power and DG Applications (cont.) Supplementing grid capacity to meet seasonal or event • related power requirements (international meetings and sporting events such as World Cup, Africa Cup, etc); • Improving power reliability and quality for high tech equipment used in industrial parks, mining operations and refineries; • Peak shaving to reduce load demand on the grid during peak times.

Advantages of MP and DG • Combustion turbines can be installed in record times (3 weeks); • Combustion turbines can be relocated to suit load shifts or be resold if no longer needed; • Provides alternatives in case of catastrophic failure of central power plants; • Avoids or reduces T&D upgrade costs; • Reduces transmission losses; Facilitates the entry of local entrepreneurs in the IPP sector • because of lower capital cost. Disadvantages of MP and DG Do not always offer economies of scale involved in central • power plants; • Depending on the applications, initial capital costs could be higher; • (see if we add some more!!!)
