Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Industrial electricity rose 4.2% over the last 12 months, but 1 of its main inputs rose faster: unprepared bituminous coal and lignite (utility sold) +9.6%. That cost pressure may still pass through to prices.

Since 2016, this index has not followed the Henry Hub gas price closely. Over most 12-month spans the two moved by different amounts, and often in different directions.
Over the 12 months to Sep 2026, the Henry Hub gas price fell 0.7% and this index rose 4.2%.
A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Industrial Electric Power (BLS series WPU0543), published by BLS. Base Period: the index value published for September 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]
Used in contracts where power is a large cost, such as steelmaking, data centers and cold storage. Industrial power is priced on different rate schedules from commercial power, so the commercial series is not a substitute. A large plant usually also tracks its own utility tariff.
Divide the current value of BLS series WPU0543 (Industrial Electric Power) by its value at contract signing, then apply that ratio to the industrial electricity part of the price. A usable clause also names an averaging window, a rule for revised values and missing months, and a cap.
Escalake tracks US PPI — Industrial Electric Power, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
