This is huge news, apparently. It won't solve the country's energy woes of course but will reduce the consumer's electricity bills substantially.
Here's a summary for the average layman:
Here's how it works:
- Your solar/wind power system produces energy which you consume for absolutely no cost.
- Surplus electricity can be supplied to the grid. Effectively making your energy meter run in reverse.
- The grid will supply extra energy if your demand exceeds supply, at a fixed cost/unit as is the norm.
- You will be billed for the net-energy (import minus export) units consumed.
Payback period is approximately five years. After that electricity would be, virtually, free provided you have a sufficiently large system installed. It is important to note that there is no back-up feature in a grid-tied system. And the system shuts down when electricity grid is off i.e. during load-shedding hours.
The net-metering facility is already well underway in countries like Canada and Germany among others.

A typical 5-kw On-Grid Solar Power Generation System installed at the consumer’s premises costing around Rs700,000 produces five units of electricity per hour. This adds up to a total of 35 units each day, considering the average daylight of seven hours available for Solar PV panels to operate.
By producing 35 units daily, a consumer can produce 1,050 electricity units every month. Assuming that the consumer is paid at Rs13 per unit, the money that can be made every month will be around Rs13,650.
If there is an average consumption of 600 units per month for domestic use, 450 units can be sold to the utility to provide an approximate benefit of Rs5,850 per month.
For an average consumption of 2,000 units per month, the consumer will only be charged for the extra 950 units consumed and end up saving a healthy amount worth 1,050 units per month.
