(1) The lesser of 2,000 kW or such DG Customer's peak load as measured over the prior twelve month period, pursuant to New York State Public Service Law §66-j and §66-l. If no prior history is available, utility will determine the limit of the size of generator based on an analysis of comparable facilities. Customer has the right to petition the PSC if not in agreement with the Company’s analysis.
(2) Net Metering is available on a “first come, first serve” basis determined by the date the utility notifies the DG Customer that it has received a complete project application.

(3) Demand customers will be subject to applicable actual metered demand charges consumed in that billing period. The Company will not adjust the demand charge to reflect demand ratchets or monthly demand minimums that might be applied to a standard tariff for net metering.
