Settlement Calculation for Net Metering/Gross Metering/Net Billing Explained

It is very important for a prosumer (who plans to install Solar Power Plant) to understand the Solar Metering Policy applicable in the state. There are various metering arrangements available like Net-metering, Gross Metering, Net Billing, Behind the meter or Zero Export etc.

Gross Metering

A consumer is compensated at a fixed feed-in-tariff for the total units of solar energy generated and exported to the grid (as measured by a unidirectional “gross meter”), you must pay the retail supply tariff to the power distribution company (discom) for the power consumed from the grid. Tariffs for feed-in and retail supply are different and Feed-in-tariff is mostly lower than the retail supply tariff.

Net Metering

Net metering is a system in which power exports are offset by imports, decreasing the electricity bill by deducting electricity generated from total electricity consumed over a set period of time. The adjustments might be made on a monthly, half-yearly, or annual basis. A bidirectional ‘net meter’ typically accounts for both power import and export. If the exported electricity is greater than the imported electricity, the surplus electricity supplied into the grid may or may not be paid depending on the state’s net metering rules.

Net Billing

Consumers can be paid for net access electricity that is generated and exported to the grid under net metering laws.


Here's the calculations explained as per MNRE on the different metering arrangements:-

𝗖𝗮𝘀𝗲-𝟭 𝗡𝗲𝘁 𝗠𝗲𝘁𝗲𝗿𝗶𝗻𝗴

Billing will be done on net drawl from grid, which is 5 kWh

Bill amount = 5x7 = Rs. 35/-

Saving to consumer = Rs. 70/- minus Rs. 35/- = Rs. 35/-


𝗖𝗮𝘀𝗲-𝟮 𝗚𝗿𝗼𝘀𝘀 𝗠𝗲𝘁𝗲𝗿𝗶𝗻𝗴

Billing will be done on amount on account of total consumption by load (minus) amount on account of total (gross) solar power generated

Bill amount = (10x7) – (5x3) = Rs. 55/-

Saving to consumer = Rs. 70/- minus Rs. 55/- = Rs. 15/-


𝗖𝗮𝘀𝗲-𝟯 𝗡𝗲𝘁 𝗕𝗶𝗹𝗹𝗶𝗻𝗴

Billing will be done on amount on account of total drawl from grid (minus) amount on account of solar power injected into grid

Bill amount = (7x7) – (2x3) = Rs. 43/-

Saving to consumer = Rs. 70/- minus Rs. 43/- = Rs. 27/-
