How it works

Electric customers that generate their own electricity from a solar photovoltaic (PV) or other renewable energy source are eligible to participate in a billing arrangement called net metering. If the generation facility is a solar PV system, first the DC electrical energy produced must be converted to AC through an inverter before fed into the utility network. The power generated in excess of the owner’s electricity consumption is fed into the grid through a bi-directional energy meter capable of registering both import and export of electricity. The arrangement of a net metering system utilizes the same service line for excess power injection into the grid which is already being used by the consumer for draw of power from utility network. However, an electrical inspection is normally carried out prior to energizing a generation interconnection to verify whether the generation arrangement meets utility, product safety and grid interconnection specifications and standards.

Net-Metering allows households to generate electricity and set off the power produced against the power used from the national grid and consumer pays only for the “net” number of units (difference between import and export energy) used each month. In the event the consumer produces power in excess of his usage in a particular month, the customer’s energy charge becomes zero and the remaining number of units will be credited and carried forward to the following month. Normally most of electricity companies allow carrying forward the excess electricity generated for up to one year period. Some electric companies (Not in Sri Lanka) may pay back to the consumer for the extra power if more energy has been injected into the system than the consumer has used.

What is Net Metering

What is Net Metering

Net Metering is simply a policy that enables electricity customers to connect their own on-site generation system to the utility grid and receive credits on their electricity bills for their own renewable energy generation in excess of their electricity consumption that is exported to the electricity distribution network. The term net metering refers to the fact that the meter can measure the flow of electricity in two directions and it is also known as power banking since the consumers can “bank” the power they generate within the utility system by feeding the grid when excess power is produced and consume power from the grid at a later time when their production falls below consumption. This form of energy exchange is especially useful for intermittent renewable energy technologies such as solar and wind.

In most utilities’ net metering systems, if the customer generates more electrical energy than he/she uses from the utility electrical system he/she will not be paid for that energy, but the customer receives only a kWh credit, which is applied to future bills. Whether the customer gets paid for that excess energy fed into the system depends on the net metering rules in the jurisdiction. While many different renewable energy sources may be eligible for net metering credits, solar rooftop installations are the most common and popular type of renewable energy source promoted with net metering. Many states have passed net metering laws and policies which allows utilities to offer net metering programs voluntarily or as a result of regulatory decisions.

Introduction - Net metering

Introduction 

Introduction In today’s world most of the developing countries are already swamped with power crisis due to inadequacy of generation as well as energy storage facilities to meet the demand. Therefore there is a pressing need to implement mechanisms to manage the growing demand and improve the efficiency while reducing the energy losses, accelerating the development of low-carbon energy technologies such as renewable power generation, in order to address the global challenges of energy security, climate change and economic growth. In this context, the on-site power sources known as distributed renewable generation is becoming increasingly competitive with centralized power sources on a financial basis due to technological innovations, reduced capital costs, reduced maintenance requirements, access to inexpensive energy resources, and other benefits.


One promising means of distributed renewable generation of electricity closer to the end user is introducing net metering schemes which encourage customers to generate their own electricity through renewable sources of power such as solar, hydro or biomass in their own premises. Net metering programs can make self-generation more attractive for customers by eliminating the need to size systems to meet customers’ exact power needs or install on-site storage and power conditioning devices. The deployment of distributed renewables through net metering also offers several environmental, economic and social benefits that are described in this report.
