A smart meter is a digital electricity meter that records usage at regular intervals and usually sends readings to your retailer remotely, so manual meter reads may not be needed. In Australia, a retailer or distributor may arrange one for a new connection, solar installation, meter replacement or tariff change, depending on local rules. Smart meters can support time-of-use pricing and help you track consumption, but available plans, installation charges and responsibilities vary. Check with your retailer or distributor, and compare the rates and fees before changing plans.
