The energy provider is believed to be resolving integration issues as a priority in order to leave the path clear for further acquisitions.
Tibco is deploying its EAI solutions across ScottishPower and its US arm Pacificorp's operations. Once complete, the company will have access to integrated corporate-wide data.
The deal will enable ScottishPower, which has some seven million customers in the UK and US, to sell and market its services with greater ease, as well as providing improved customer services.
Aditya Shrivam, Tibco's product marketing manager, said: "They wanted to solve this now, because when - or if - they embark on future acquisitions, they want to be able to seamlessly role new company IT infrastructures into theirs."
ScottishPower was deregulated in 1995 and found almost immediately that it needed to find a way to integrate data throughout its enterprise. Since then it has been using a largely homegrown solution, scattered with integration components from various vendors, Tibco being one of them.
"The point solution-based offering ScottishPower was previously using was expensive and didn't have a consistent process flow throughout the enterprise," added Shrivam.
The Tibco system will be used for internal and external operations, affecting areas of the business such as billing, customer service, call centre operations, workflow management and procurement.
David Jones, group chief information officer at ScottishPower, said: "We chose Tibco because of its proven track record to deliver an end-to-end integration solution and common robust platform across all sectors of our business, both internally and externally."
This is unlikely to be the end of Tibco's involvement with ScottishPower, according to Shrivam, who describes the deal more as a strategic relationship.
"This is not a one-off thing," he said. "You can always improve customer service and price-definition."
