Make the switch and save money

Want another way to improve your bottom line? Sign up for Dual Fuel service. With this plan, you'll enjoy significantly lower rates all year for agreeing to switch to an alternate fuel source during peak demand days. You can expect natural gas savings of up to 20 percent before curtailment costs.

Program details

Average January usage of 20,000 therms:
7,000 gallons #2 oil storage
