New Learning Center pages show how different resources help keep grid in balance


Many different resources help achieve the balancing act that keeps the power system stable. Two new pages on the PJM Learning Center show how regulation resources and reserves help keep the system in balance.

The PJM Learning Center is the online source dedicated to explaining in simple terms the power industry and PJM’s key priority of ensuring reliable power supplies.

The centerpiece of the new Ancillary Services Market page is an animated graphic that shows how regulation and reserves help even out “tips in the scale” to balance the grid.

The new Regulation Market page explains how regulation helps match generation and demand and illustrates an analogy for the different types of regulation products. A page about Reserves has also been moved to the Ancillary Services Market section of the website to make it easier to find information about these interconnected topics.
