How to Become an Electricity ESCO

To be eligible to participate in NYSEG supply choice program, suppliers must first apply to and meet the requirements of the Public Service Commission (PSC) and the New York Independent System Operator (NYISO).

The PSC can be contacted at 518.486.2432 and the NYISO at 518.356.6060.

ESCOs (Energy Service Companies) that the PSC and the NYISO determine eligible to participate then must submit forms and agreements  (see Electric Qualification Steps below) to NYSEG and meet operating standards, where applicable.

For your convenience, the Supplier Manual  is available online.
