Note 1: The monthly gas usage on your Vineyard invoice may vary slightly from the usage on your NFG invoice due to the fluctuations in meter read cycles. VOG invoices customers on a monthly basis (1st of the month to EOM), whereas, NFG invoices transportation customers based on the meter read cycle as determined by NFG (i.e. If your meter is read on the 15th, your usage will be based on the read taken on the 15th of the pervious month and the 15th of the current month). Please contact your Marketing Representative if you should have any questions regarding your billing cycle.
