3rd October 2023

Callisto, a leader in regulated data services in the energy sector, has been selected to provide new Smart Data Services (SDS) and Advanced Data Services (ADS) for OVO.

The partnership between Callisto, a part of M Group Services Energy Division, and OVO, a leading energy supplier in the UK, is a key part of the ongoing transformation of the energy landscape.

The partnership will contribute to a more cost-effective electricity system, encouraging flexible use of energy by residential consumers, as the industry works to achieve the UK’s net zero target.

The five-year agreement builds on the existing relationship between Callisto and OVO. Callisto will work as the trusted custodian of settlement activities, overseeing and supporting settlement operations.

Stephen Burke, Managing Director of Callisto, said: "This partnership is a significant leap forward within the industry and cements OVO’s commitment to providing cutting-edge solutions for its customers.

"We are proud to be chosen as OVO’s strategic partner reflecting our joint dedication to the MHHS programme."

This collaboration promises to reflect both businesses’ shared commitment to innovation, reliability, and customer-centric solutions.
