What does PJM stand for in the context of electric grid management?

In the context of electric grid management, PJM stands for Pennsylvania-New Jersey-Maryland. This organization is a regional transmission organization (RTO) that coordinates the movement of electrical power in parts of the United States. It was established to ensure the reliability of the power grid and to promote efficient electricity markets across the three states, which later expanded to include additional regions.

PJM plays a critical role in balancing supply and demand, facilitating energy trading, and managing grid operations. Its primary objectives involve enhancing grid reliability, optimizing resource utilization, and supporting market operations in the electricity sector. By understanding the geographical and operational implications represented by its name, it becomes clear how PJM serves as a pivotal entity in the U.S. energy landscape, overseeing and coordinating a large network of electricity generation and transmission.

The other choices do not correctly reflect the formal designation of PJM and therefore do not pertain to its role in electric grid management.
