Make a utility-and-commodity account map

List electricity and gas separately for each service address. A property can have different delivery arrangements for the two commodities, and a regional brand can represent different operating utilities. Use the legal utility name, account identifier and rate class from the bill rather than a general corporate logo.

Con Edison’s official information describes its delivery role and ESCO supply choice. National Grid’s business resources identify territory-specific supplier information. Use the correct territory and commodity resource; a Long Island gas page or an upstate electricity page should not be treated as universal New York business eligibility.

Compare the actual supply choice within each utility

For every eligible account, identify current supply, available default arrangements and competing ESCO proposals. Review included charges, fixed or variable formulas, recurring fees and contract dates. New York commercial-class rules and products can differ from residential shopping summaries, so verify the applicable documents.

Changing an ESCO does not replace the local delivery network or emergency response. Keep delivery and supply costs distinct in a worksheet. An account with a high demand component can have a different total cost profile from a gas-heated site whose principal energy expense is winter therms.

Hypothetical mixed-commodity example

Consider one property with 15,000 kWh of electricity and 2,000 therms of gas in a period. At invented supply prices of $0.10 per kWh and $0.70 per therm, modeled commodity costs are $1,500 and $1,400. Adding the quantities to call the property a 17,000-unit energy user would be meaningless; add the $2,900 while preserving each unit separately.

Neither price represents Con Edison, National Grid or an ESCO offer. Delivery, demand, taxes and fees are outside the example. For an annual comparison, include full seasonal histories for both fuels instead of assuming the selected period repeats twelve times.

Keep enrollment authority and billing evidence clear

Confirm which entity can authorize each account change, especially in leased buildings with landlord-paid heat or common-area electricity. Ask an ESCO to identify the named contracting seller and the utility accounts in scope. Save the accepted terms and inspect subsequent bills for the intended supply designation.

A useful comparison may reveal a procurement opportunity on one commodity and no attractive change on another. Do not force a combined recommendation simply because both utilities appear in the portfolio. This guide provides no universal utility winner or current rate claim; it helps a business avoid confusing delivery territories, fuel units and supplier contracts.

Questions & answers

Could my building have different utilities for electricity and gas?

Yes. Read each bill and map the commodity and meter separately rather than assuming one brand covers every service.
