The net-metering provision as approved by the NH PUC limits net-metering to 1% of a utility's historical peak load. National Grid has a historical peak load of 188 MWs, making the 1% limit 1,880 KWs.
As of March 27, 2012, there are 156 KWs with net-metering service. There are 72.33 KWs with net metering applications in the process of being interconnected.
Who is eligible:
Customers with renewable generation systems up to 100 kVA
NET IMPORT OF POWER OVER BILLING MONTH
If your generation system produces less power during a billing month than your facility/home uses during that billing month, you only have to pay for the net amount of power you draw from the grid. The power you generate and use on site is worth "full retail value". For example, if your generator produces 700 kWH over a billing month, but you use 1,000 kWH in your facility/home, you will have a net import of 300 kWH over the billing period. You will only have to pay energy charges on the net 300 kWH. The power you generate has a real value equivalent to the full retail value.
NET EXPORT OF POWER OVER BILLING MONTH
If your generation system produces more power than your facility/home uses during the month over which you are billed, your account will carry forward the excess power as kWH credits. For example, if you use 1,000 kWH in your facility/house over a month, but your generator produces 1,300 kWH, you will export a net 300 kWH to the grid. You will not have to pay any energy related charges during that month and your account will carry forward a credit of 300 kWH which can be used in subsequent months.
