New York technically allows ESCO (Energy Service Company) supply, but the NY Public Service Commission has documented that most ESCO customers pay MORE than the default utility rate. A 2020 study found ESCO customers in NY paid $1.2B more than default supply customers over four years. Most New Yorkers should stay with their utility's default supply.
Check your current bill — is your supply already an ESCO? If so, the utility's default rate is almost certainly cheaper.
If you want to shop, only consider 100% renewable plans where the premium funds RECs.
Avoid all variable-rate ESCO offers — the PSC has documented chronic overcharging.
If you're already with an ESCO, switching back to utility default is free and takes 1 billing cycle.
When you switch suppliers, your delivery utility doesn't change — they still maintain the wires and respond to outages. Only the energy charge on your bill changes.
