6 FAQs about [Bulk electric system vs bulk power system]
What is a bulk power system (BPS)?
NERC defines the bulk power system (BPS) as the facilities and control systems necessary for operating an interconnected electric energy transmission network (or any portion thereof); and electric energy from generation facilities needed to maintain transmission system reliability.
What is a bulk electric system?

What is a fine bulk power system?
fine Bulk-Power System? What equipment is included/excluded? The Bulk-Power System is the facilities and control systems necessary for operating an interconnected electric transmission network, to include those lines rated at 69 kV or more, and
Does NERC use the term 'bulk power system'?
NERC‟s reliability standards, however, do not generally use the term “bulk-power system.” The current standards were adapted from NERC‟s pre-EPAct operating policies and planning standards, which used the term “Bulk Electric System” or “BES” to identify their scope.
What are the components of bulk power system reliability?
Reliability is often measured and evaluated separately on the distribution network and the transmission/generation network. Components of bulk power system reliability include three elements that we refer to in this document as the “three R’s”: resource adequacy, operational reliability, and resilience (Geocaris 2022). Figure 1.
Why is reliability important in a bulk power system?
Maintaining reliability of the bulk power system, which supplies and transmits electricity, is a critical priority for electric grid planners, operators, and regulators. As we move toward a cleaner electricity system with more technologies like wind, solar, and battery storage, the way in which we plan for and achieve reliability will change.
