Direct answer
Variable or index supply contracts tie commodity price to published market indices plus supplier margin. They may beat fixed during low-price periods but expose laundromats to spikes when vended prices stay constant. Massachusetts medium C&I basic service is already monthly variable—compare supplier variable to utility default before switching. Review bandwidth, caps, and pass-through definitions. Jaken Energy helps evaluate fit; we do not guarantee index outperforms fixed.
