Net Metering – Between December 2014 and May 2015, nearly 821 MW solar capacities have already been added across India. No wonder solar energy segment has been flourishing following Indian government’s decision to revise the target from 20GW to 1 Lakh MW, a fivefold increase, by 2022.
Scaling to 100GW from the current 3.8GW capacity is a huge, and achievable task. The decision has attracted investment, and led to various technological and business innovations. These together have opened up the possibilities to ‘solarify’ India.
Solar rooftop grid connected system under net-metering scheme is one such way of switching to solar and achieve the set target. In fact of the 100 GW, 40 GW has been reserved for this segment.
Net-metering is the process whereby consumers can sell the surplus energy generated from their solar power system. The scheme allows consumers to export/feed the surplus energy generated by the installed power plant at a rate fixed by respective state regulatory commission to the distribution licensee of their area. At times when generation from the system falls short of the demand, energy can be drawn (imported) from the grid.
The electricity bill is calculated on the net units consumed from the grid.
Net Units = Imported Units – Exported Units
The regulations governing net-metering policy differ from state to state.
The regulations governing net-metering policy differ from state to state. For example, Haryana provides incentive @25 for every unit generated from the Solar Power system. Whereas every unit exported to the grid can be sold at @INR9.56 in Karnataka and @INR9.20 in Uttrakhand.
