What Is Power Export Metering?

The power export metering is a concept which is directly related to those electricity customers who are installing their own electricity generating equipments. These are the customers who own some small renewable energy facilities, such as wind, solar power or home fuel cells. This article explores in details what is power export metering in the following manner. So, what is power export metering? Let us take a look:

When a consumer is producing more electric power than he actually requires for his own use at home, the surplus energy may be exported back to the power grid. This phenomenon is known as power export metering. The consumers who want power export metering need to have special equipments or safety devices to protect the grid components as well as their own while sending the electricity back to the grid. The safety equipments ensure that no damage happens in case of faults like electrical short circuits.

Most net metering laws involve monthly roll over of kWh credits, a small monthly connection fee, require monthly payment of deficits (i.e. normal electric bill), and annual settlement of any residual credit. Unlike a Feed-in Tariff or time of use metering (TOU), net metering can be implemented solely as an accounting procedure, and requires no special metering, or even any prior arrangement or notification.

In simplest cases, this amount of exported energy to the grid may be accounted for by the meter running backwards during periods of net export. This will result in the reduced usage of electric power by the consumer. The customer's recorded energy usage decreased by the amount the energy exported by him to the grid. These days there are so many meters which permit this kind of export and maintain all the data about the energy consumed by the customer and the energy transferred by him to the grid. The advanced and sophisticated meters permit such exports in power export metering. There is a system known as net metering in which the owner gets the retail credit for at least a portion of the electricity which is generated by him. The majority of electric meters are accurate in recording the flow of electricity in both directions, allowing a no-cost method of effectively banking excess electricity production for future credit. Nevertheless, there may be different rules in different countries and possibly in different states with in a same country. So, if power export metering is available, you should check for how long you can keep your banked credits, and how much the credits are worth. In the recent times, the upload sources typically originate from renewable sources or gas or steam turbines, which are often found in cogeneration systems. Vehicle-to-grid systems can also be set up at workplace, garages, and parking lots at park and rides and could help drivers charge their batteries at home at night when off-peak power prices are cheaper, and receive bill crediting for selling excess electricity back to the grid during high-demand hours.

You can find more information about power export metering on the internet, although it is relatively a newer concept. The power export metering is quite popular in Canada. Some pilot projects have also been set up in United Kingdoms to check if this concept can succeed in Britain.
