NET METERING POLICY – WEST BENGAL
Net metering is the mechanism that allows distribution companies monitor the user’s energy production and consumption. This mechanism also allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated. For an instance, consider a prosumer is generating and consuming the electricity and has surplus amount of energy. The surplus amount of energy is feed into the grid. There is another facility to transfer the surplus energy into the grid and use the same amount anytime. This facility is called as Banking.
The net metering policy can vary significantly from country to country and state to state. Most net metering laws involve monthly rollover of kWh credits. Net metering uses the single, and bi-directional meters and can measure the current flowing in both the directions. Net metering can be installed and solely responsible as an accounting procedure, requires no special notification or arrangement. The list of aspects considered for net metering policy are listed one by one for West Bengal.
