Energy Decision #16: C&I Demand Charges Explained: Why Using Less Power Doesn't Lower Your Bill

Demand charges are one of the most significant and least understood components of a commercial and industrial electricity bill — and for many operators, they represent more than half of what they pay every month. This is Energy Decision #16 in the complete C&I energy management series from Tactical Energy Group. 100 decisions. Every one that matters. In this episode, Daniel Burke covers: Why reducing total energy consumption does not automatically lower your electric bill. The three charge types on every utility bill: fixed charges, energy charges, and demand charges. The difference between kilowatt-hours (kWh) and kilowatts (kW) — and why that distinction controls your costs. How the 15-minute interval measurement window determines your billing demand for the entire month. Why demand charges commonly exceed 50% of a C&I electric bill. Max/non-coincident demand, time-of-use demand, flat, tiered, and daily demand charge structures. How demand ratchets work — and how a single summer peak can determine your winter bills. Load shifting and load staggering as near-term demand management tools. Battery energy storage for peak shaving — when the math works and when it doesn't. The direction utilities are heading: residential demand charges, daily demand structures, and heavier TOU weighting. Who this is for: plant managers, facility managers, operations executives, and financial leaders at manufacturers, hospitals, schools, municipalities, and large commercial facilities who are trying to understand why their power bill keeps climbing even when they're trying to cut usage. If you're asking "why did my electric bill go up when I used less power" — this episode is built to answer that question.
