In the energy sector, dispatch is the operational planning of power plants. It is the process in which transmission system operators decide which power plants and generation plants are used to meet current electricity demand. This involves optimising costs and efficiency while ensuring security of supply.
What Is a Power System Dispatcher?
A power system dispatcher directs the distribution of electricity between providers and consumers, both residential and commercial. As a power system dispatcher, you monitor generator systems to ensure optimal efficiency and determine how much power is needed for each day. Discretion is particularly vital during extreme weather conditions, such as heat waves or snowstorms. Other job duties include responding to calls of shortages or repairs and coordinating crews out to the location to fix the problem.
What Are the Education Requirements to Become a Power System Dispatcher?
Power system dispatchers need to have a high school diploma or equivalent. They also need to complete an apprenticeship in electrical dispatching or electric utility operations. These apprenticeships typically last two to three years. To become a power system dispatcher, you must know GIS applications and electric utility systems such as SCADA, an understanding of how to build and maintain a database, and know how to read electrical circuit drawings.
Where Does a Power System Dispatcher Work?
A power system dispatcher works in an office setting, often in a power plant. They monitor equipment using a computer, coordinating with crews to complete needed repairs, and communicating with engineers and planners to provide information about clearances, orders, and distribution changes. Some positions may require you to work out in the field to monitor repairs and new installations. You may also travel to other offices to discuss power supplies and other issues.
What Is a Typical Work Day for a Power System Dispatcher?
During a typical workday for power system dispatchers, they regulate, track, and monitor energy distribution. To ensure all clients are receiving the correct amount of electricity at all times without disruption, you operate various supply equipment, monitor transmitters, and regulate the power flow as needed. Rotating shifts are common and being at a workstation may be required for your whole shift. You communicate with power plant operators, traders, and local companies frequently, and take note of any weather changes that may affect service. Power system dispatchers may need to be on call for emergencies, and sometimes work evenings, weekends, and holidays.
