Public Utility Commission (PUC)
A state-level regulatory body (also called PSC, BPU, or CPUC depending on the state) that oversees utility operations, approves rate changes, and sets interconnection rules.
Why It Matters
Your PUC determines net metering rules, interconnection procedures, and rate structures. PUC decisions directly affect the economics of solar and storage in your state.
