MOSL selects CGI to deliver smart data hub

MOSL has selected CGI as delivery partner for the new smart meter data hub for the non-household retail market.

This follows the Strategic Panel’s decision that a central hub would be be best way for wholesalers to share non-household customers’ smart meter reads with retailers. The hub will provide a consistent approach to sharing smart meter reads, while allowing trading parties to submit or extract data in different ways and formats, depending on their needs, capability and budget.

CGI said the Smart Meter Read Hub will be a secure, modular, and cloud-native platform designed to meet the evolving needs of the market. The hub will support both ad-hoc and scheduled data extraction, audit logging, and robust validation against minimum field standards.

CGI said the hub would deliver several key outcomes, including:

• Enabling market-wide efficiency by replacing multiple wholesaler-retailer data exchange processes with one centralised, standardised data hub.

• Reducing market barriers for new or smaller retailers by simplifying data access and integration processes.

• Future-proofing CMOS settlement by allowing it to handle over one million meter reads per month, supporting more frequent read submissions and smart tariff innovation.

• Providing enhanced regulatory insight through secure, aggregated data sharing.

The hub is budgeted to cost £1.1m to build, which will be funded from market performance charges. Ongoing running costs will be funded through MOSL’s Market Operator charges.

The first phase of the hub is due to be delivered in Spring 2026, followed by a second phase to connect the hub to CMOS to allow retailers to submit reads directly into the market’s central system for billing and settlement purposes.
