This issue concerns the ability to provide better quality regulation and to send more rapid regulation signals to more flexible resources. The emergence of alternative technology resources capable of near instantaneous changes in output in response to the control signal sent to them provides the opportunity to implement a faster regulation signal. However, no compensation model exists in PJM to recognize and reward this unique capability or provide incentives to respond more accurately to the traditional regulation signal used today. The existing PJM regulation market compensation scheme lacks the ability to distinguish between good and poor performers and prevents the ability to utilize new technologies to their full capability. Additionally, the North American Electric Reliability Council (NERC) has identified reliability concerns due to the declining frequency responsiveness of the US interconnections.
