CPG operates 15,000 miles of interstate pipelines across the USA.
The deal includes services relating to the cloud, to mobile, to analytics and to security.
CPG span itself off from infrastructure company NiSource at the beginning of its month and NiSource was already an IBM customer.
But this deal will provide the technology infrastructure for CPG, which has assets worth about $4.6 billion this year.
IBM will move CPG’s IT and apps covering human resources, billing and finance, pipeline operations and IT management from NiSource’s data centres into an IBM data centre based in Columbus Ohio.
As well as the shift of data, IBM will also manage its IT environment including help desk, end user services, mobile device management, and operational analytics.
