The Demand Charge
Subject area

Cost Models, ROI and Incentives

A demand reduction project competes for capital against everything else the business could buy, and it wins or loses on the same terms: payback, internal rate of return, effect on the cost line. This section builds those cases. It covers avoided-cost modeling from interval data, how to price a kilowatt of avoided peak correctly when a ratchet is in force, total cost of ownership for batteries and controls, federal investment tax credit and depreciation treatment as they apply to energy equipment, utility incentive and demand response program payments, and measurement and verification protocols rigorous enough that a finance function accepts the savings claim. The recurring theme is that the engineering is usually right and the financial framing is what fails.

The base demand rate is not the answer. Riders, taxes, the ratchet and seasonality all change the figure, usually upward, and the correct number decides every project after it.
