Export power back to ECG to balance your monthy bill
What is Net Metering ?
Net Metering is a regulatory model that allow electricity producers to “export” surplus to the national grid, and use the “exported” electricity to balance out deficit, allowing households/organizations to meet their own electricity demand with their own production.
This is particularly important with wind and solar. Monthly net metering allows consumers to use solar power generated during the day at night, or wind from a windy day later in the month. Annual net metering rolls over a net kilowatt credit to the following month, cutting the cost of electricity for the consumer.
In a typical Net Metering system, electricity is usually generated by a renewable source permitting households and organizations to produce their own electricity. The electricity generation is sized to match the consumer’s consumption. The system is integrated with the grid, allowing surplus electricity produced to be fed into the grid while any deficit in production is compensated by the grid. For instance, a household with a solar system install will usually generate a lot of electricity during the day. In a case where this household has few batteries, the battery charges up quickly and the surplus electricity is utilizes during the day or goes “wasted”. But in a Net Metering system, the excess electricity produced will be transported to the grid and can be used later when the consumer’s batteries run down.
Measuring the electricity produced and consumed is very important in the Net Metering system. To measure the produced and consumed electricity, a reversible meter is usually installed. This will not only allow excess electricity to be exported to the grid but will measure the exact amount of electricity exported. The billing is based on the net amount of electricity consumed per billing period- the difference between amount of electricity consumed and amount produced. If a household produces more than it consumes, the surplus carried over.
