Update - 22nd June 2021

As you are aware the Gemini System Enhancements (GSE) project was due to make APIs available over the internet on 25th July 2021. Protecting the data security of our customers is of the upmost importance, and to enable more robust security monitoring and control for the APIs to be in place, we have made the difficult decision to delay the launch of APIs over the Internet until Q3 2021.

We apologise for any inconvenience this may cause.

The remaining changes being made as part of the GSE project are listed below, and are still planned to be delivered on 25th July.

1. Changes to existing screens
2. Changes to the Meter Look-up facility
3. Introduction of 2 new report screens
4. Introduction of a Dashboard facility
