What to establish before acting
Identify the ESCO legal entity, delivery utility, service class, account identifiers, and actual supply status. New York DPS provides shopping and verification guidance. Commercial categories can affect the applicable framework, while electric and gas programs remain distinct. Ask for complete component scope, reset or adjustment formulas, renewal, fees, and authority. NYISO market information helps explain wholesale context but cannot replace account-specific retail terms or the utility’s tariff and enrollment process.
Illustrative decision boundary
A hypothetical company sees a residential offer online and assumes it prices a large demand-metered site. That assumption can fail because the class, load, scope, or eligibility differs. Request a commercial offer using the actual meter information and preserve the proposed product’s applicable terms.

Questions & answers
What is an ESCO?
An Energy Service Company can provide supply to eligible customers under the applicable arrangements. It is distinct from NYISO and from the utility’s physical delivery role.
Can one ESCO agreement include electricity and gas?
Possibly, but verify the actual fuels, entities, accounts, units, terms, and authorizations. An electric enrollment does not prove the gas account is included.
Does Con Edison deliver even with an ESCO?
For its eligible service arrangements, the utility retains delivery responsibilities. Direct outage and infrastructure issues through official utility channels rather than assume the ESCO controls restoration.
Can I compare with a wholesale NYISO number?
Only as a scoped market reference. Location, load weighting, capacity, losses, fees, other services, and delivery separate a retail bill from a wholesale energy series.
What should I verify about an intermediary?
Confirm the current applicable state requirements, exact legal entity, compensation, relationships, and granted powers. A title or familiar brand alone does not establish suitability or unlimited authority.
