Definition of net metering in US English:

net metering


  • A system in which solar panels or other renewable energy generators are connected to a public-utility power grid and surplus power is transferred onto the grid, allowing customers to offset the cost of power drawn from the utility.

    • ‘Two years ago, E reported that 23 states mandated some form of net metering.’
    • ‘How do you incentivize wind energy and solar and make sure that net metering, for example, occurs?’
    • ‘With net metering, surplus solar power in excess of instantaneous loads spins the revenue meter backwards.’
    • ‘By using the utility grid as a giant battery to store excess energy, net metering alleviates the need for expensive batteries and directly affects the economics and payback period for the investment.’


Surplus energy, measured by an electric meter, is netted from the amount passing from the utility to the customer.
