Cement manufacturer, Hualien, eastern Taiwan
Problem
size behind the meter storage for a heavy industrial cement plant on a high voltage tariff.
Work
- reviewed the plant's contract capacity history, decomposed the time of use bill into its component charges, and built a revenue stack around peak shaving and time of use arbitrage.
peak shaving, not arbitrage
on this tariff, peak shaving against the existing contract capacity carried most of the modelled revenue stack, with time of use arbitrage as a secondary contributor rather than the main case.
Consequence
the sizing case was built around demand charge avoidance first, with arbitrage revenue treated as upside rather than the primary justification.
