PJM Generation Dispatcher Practice Exam 2025 – Complete Preparation Guide

Forecasting is vital for Generation Dispatchers because it directly informs decisions about resource deployment. Accurate forecasting allows dispatchers to predict electricity demand and generation needs based on various factors such as historical usage patterns, weather conditions, and expected system changes.

When dispatchers have a clear understanding of anticipated demand, they can efficiently allocate resources to meet that demand. This ensures that the right amount of generation capacity is online at the right time, minimizes the risk of outages or supply shortages, and enhances the overall efficiency of the power system. Forecasting also allows dispatchers to make informed decisions about which generation units to bring online or offline, optimizing fuel use and cost-efficiency.

This strategic alignment between forecasting and resource deployment ultimately leads to improved reliability in the power supply and can have positive financial implications for the utility.
