What is GEM?
GEM is an energy tracking and reporting tool that gives you greater visibility of your household energy usage and the opportunity to reduce your energy consumption and cost (‘GEM Service’).
How do I access the GEM Service?
To access the GEM service, log-in to My Account on the Mercury website (mercury.co.nz). By using the My Account service, you agree to receive the full range of GEM Services that we may from time to time offer as well as agreeing to these GEM Terms and Conditions.
Who is GEM available to?
Not all GEM features are available to all customers or all types of electricity meters. The type of GEM features available are largely dependent upon what type of meter you have; a smart meter or another type of meter.
Even if you don’t have a smart meter, you can still experience many of the benefits of GEM:

Projected Bill Estimate
Your past energy usage is not necessarily a reliable predictor of future usage. Your actual bill will differ from your projected costs as your bill is based on your actual usage, current energy prices and any other charges. Data may be estimated if actual meter reads are unavailable. The amounts shown include GST and assume that you have or will receive Mercury's Prompt Payment Discount, even if you did not or will not receive that discount, for the period shown. The projected bill estimate is a feature available to customers with smart meters.
The amounts shown in the cost view include GST and assume that you have received Mercury's prompt payment discount, even if you did not receive that discount for the period shown.
The daily and half-hourly views are only available to smart meter customers and only show the variable cost component and do not include the daily fixed charge. Please be aware of this if comparing against your total bill. Data may be estimated if actual meter reads are unavailable.
Bill comparisons are based on your actual usage and current energy prices at the time of each bill and do not account for any price plan changes. The amounts include GST and assume that you have received Mercury's Prompt Payment Discount, even if you did not receive the discount for the period shown. Data may be estimated if actual meter reads are unavailable. Bill comparisons are available for all customers.

Actual savings and efficiencies may vary subject to your personal circumstances, including individual appliances, how you use them, current energy prices and your household's consumption.
