Openreach enhances partnership with Google Cloud AI.

      Openreach, a BT subsidiary that manages the largest broadband network in the UK and the second-largest commercial fleet in the country, has developed a digital twin of the UK's transport and broadband infrastructure using Vertex AI. The company is leveraging Gemini Enterprise to reduce engineering overhead by over 50%.

      Openreach announced on Wednesday that it has bolstered its partnership with Google Cloud to integrate AI into two of its most demanding operational challenges: providing full-fibre broadband to 25 million premises by the end of 2026 and decarbonising its fleet of 24,000 commercial vans that collectively travel nearly 200 million miles annually.

      The fleet initiative utilizes BigQuery. Openreach has transferred its fleet telematics data to Google Cloud and is employing the platform's geoanalytics features to determine the most effective locations for replacing diesel vans with electric vehicles based on actual routes, usage patterns, and charging infrastructure.

      This analysis has expedited Openreach's transition to electric vehicles, with the company reporting that the additional electric vans deployed are reducing approximately 10,000 tonnes of CO2e emissions from the roads each year.

      The same analytical approach is being employed to minimize idling and unnecessary driving, particularly in clean air zones, while also reducing vehicle downtime by predicting maintenance requirements before issues arise.

      For the broadband network, the work is based on Vertex AI. Openreach has created what it calls a digital twin of the UK's transport corridors, combining data from 35 million homes and businesses with the national road, rail, and waterway networks, alongside its existing fibre infrastructure.

      The model serves a practical purpose: it enables planners to pinpoint where full-fibre can be most efficiently extended, streamlining routing decisions that would normally demand manual analysis of numerous disconnected datasets.

      Openreach has already connected 22 million premises with its full-fibre network and aims to reach 25 million by December 2026, with a long-term goal of 30 million by the decade's end.

      The third aspect focuses on internal engineering efficiency. Openreach is utilizing Gemini Enterprise, Google Cloud’s agent orchestration platform, to automatically transform complex legacy SQL queries into clean, production-ready BigQuery code.

      The company claims this has cut time-to-insight by over 50%, allowing its data engineers to shift from manual code maintenance to concentrating on developing new solutions.

      This case is specifically defined yet measurable: migrating legacy queries is one of the more consistent opportunities to showcase AI-driven productivity improvements within a large infrastructure organization burdened by significant technical debt.

      Openreach operates as a wholly owned, independently governed subsidiary of BT Group and functions on a large scale: it serves more than 680 service providers, including BT, Sky, TalkTalk, Vodafone, and Zen, through equal-access wholesale pricing, employs around 28,000 individuals, and reported revenues of £6.157 billion for the fiscal year ending March 2025.

      The £15 billion investment in full-fibre infrastructure represents one of the largest capital programs in UK telecommunications history. The partnership with Google Cloud is part of the operational framework of this initiative; however, neither company disclosed the financial details of the expanded collaboration.
