The un utilized electricity injected to the system is credited to the consumer account which can be utilised in that financial year.

It is a consumer meter which is a bi-directional energy meter for measuring the amount of electricity flowing in opposite directions and the net amount of electricity either consumed by the consumer or injected into the distribution system (grid) of the licensee in kWh (electricity units).

Either consumer or distribution licensee shall procure the meter. The distribution licensee shall test and install the same. The cost of meters, cost of connectivity and all other related cost for setting up the meters etc. have to be borne by the eligible consumers under guidance of the concerned distribution licensee. (As per OERC Net Metering Order No.OERC-Engg. 02/ 2010/ (Vol-IV)/ 1131, Dated: 19.08.2016)Cost of meter will be as per the prevailing rate at that point of time.
