Billing Services Agreement:

If you are interested in having National Grid perform consolidated billing services, then please also email a separate scanned copy of the appropriate agreement form below as well as a copy of Appendix A: Terms and Conditions.

The Appendix A contains the Terms and Conditions for National Grid’s Purchase of Accounts Receivable Program for both territories and is incorporated by reference into both forms of agreement and should be printed out and kept for your records.

Once the application and creditworthiness requirement are satisfied you must complete EDI Phase III testing with the company.

You will be required to post a cash deposit based on the level of testing required which will accrue interest, and be refunded at the time of commencing retail sales in the Company's service territory. If, for any reason the ESCO fails to commence retail operations within three months of completing EDI testing, the deposit will be forfeited to the Company.

EDI Core Transactions only: $5,000
EDI Core Transaction and Single Bill Testing: $10,000

Please reach out to Konica and Greg for the documents required to proceed with EDI testing. 

You may refer to the PSC website for additional information on EDI Data Dictionaries and Implementation guides. 

Once the above steps are met, we will notify the PSC that you are eligible to participate in our Gas Retail Access program. Your name will also be added to our Energy Supplier list and website.
