What is Smart Energy Meter?
A smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor. Smart meters communicate the information to the consumer for greater clarity of consumption behavior, and electricity suppliers for system monitoring and customer billing.
What is ABT system?
Availability Based Tariff (ABT) Mechanism is adopted for pricing bulk power across various stakeholders. ABT is concerned with the tariff structure for bulk power and is aimed at bringing about more responsibility and accountability in power generation and consumption through a scheme of incentives and disincentives.
Do smart meters need WiFi?
No. Smart meters use an entirely separate, bespoke wireless system. You don’t need Wi-Fi in your home for it to work and it won’t use your Wi-Fi if you have it. Your smart meter and in-home display communicate via a secure national network which is solely for smart meters.
