Net metering means that both the electricity produced and consumed by a household or investor is measured. The prerequisite for net metering is economic viability of the net-metered electricity source compared to the grid price. This is also referred to as grid parity, a situation where it is cheaper to produce one's own electricity than to buy it from the national utility.
Net metering has been successfully implemented in both developed and developing countries.
The economic case is primarily built on the fact that certain renewable energy generation costs have reached, or will shortly reach, grid parity in many developing countries.
