How PJM and Generators Continually Balance the Grid


A new Learning Center page, How PJM and Generators Continually Balance the Grid, explains and shows – through creative animations – how at all times, the electricity generated and sent out onto the bulk electric power grid must match customers’ demand for it. This requires a constant balancing act achieved by PJM dispatchers working hand-in-hand with generators and other energy suppliers.

The page covers:

  • How the grid is balanced
  • What the signals to generators mean
  • How the markets affect the way PJM schedules generation
  • Looking at the Day-Ahead Market
  • Looking at the Real-Time Market


The Learning Center at is a 101-level education online resource source dedicated to explaining in simple terms the energy industry and PJM’s key priority of ensuring reliable power supplies.

It provides readers with information on a wide range of subjects, from electricity basics to innovations in the industry.  Featured articles cover such topics as grid security, how PJM interacts with the Federal Energy Regulatory Commission and the Regulation Market.
