Compare two supply offers
Use one month’s therm usage, prices in dollars per therm, and monthly supplier fees. Only compare offers with equivalent included services. Delivery, tax, volume settlements and other excluded items are not modeled.
Formula: therms × $/therm + monthly fee. 10 therms = 1 MMBtu. CCF and Mcf need the utility’s heat-content conversion and are not converted here.
Ask about an offer →Work backward from a deadline
Enter the actual notice deadline from the agreement, then choose how far ahead to start preparing. This is date arithmetic, not a legal interpretation or an automatic reminder.
Check required notice method, time zone, receipt conditions and business-day rules in the agreement. Add the verified deadline to your own calendar; this website does not send reminders.
Ask about a renewal →Unit reference: EIA units and calculators. For a contract comparison, use the full offer worksheet.
