Universal Supplier Service.

In partnership with Utiliteam, Universal Supplier Service (USS) has been developed to deliver a highly automated managed data service for all key industry interoperability processes. 

We manage over 2.7 Million Data Points across 7 energy retailers.

Callisto and Utiliteam negotiate the complex industry interoperability processes – significantly reducing the complexities of operating as a licensed supplier in a competitive market. Therefore, allowing suppliers to focus on customer service and growth.

In addition, the synergy benefits offered by USS in tandem with our data services, guarantees total end to end process ownership, low exceptions, and complete data alignment. Thus, enhancing read to bill performance, reducing operational cost, while strengthening industry settlement performance.

The USS market messaging system (MMS) software is maintained and continuously improved by Utiliteam, whilst the USS Managed Service (including Non-Half-Hourly Data Collection & Data Aggregation Services) is operated by a team of Callisto data specialists.

“ESB recently procured the services of USS to provide a bespoke market messaging service for our electricity supply licence which provides a route to market for our distribution connection generation assets. USS has been excellent to deal with and a key counterparty to us in successfully delivering this project. In particular, USS made themselves available to us to help with queries and issues as they arose, and the level of knowledge and expertise they brought has been very valuable.” – ESB Networks

“It was clear from the start that USS had the right people and processes to support the mobilisation of Champion Energy into the SME electricity supply market. As expected, their depth of industry knowledge and skills were first class. More importantly, their ability to flex to Champion’s unique requirements and the challenging market conditions around COVID-19 highlights their professionalism. We recommend them highly.” – Champion Energy
