Uniper generates, trades, and markets energy on a global scale. Based in Düsseldorf, Germany it ranks among the largest generation and trading companies in Europe, combining a balanced portfolio of technologically advanced large-scale assets with outstanding technical and commercial expertise. At the beginning of 2018 the company completed a major data infrastructure overhaul, which saw the existing data warehouse approach replaced by its new ‘Atonyx’ data platform that combines the flexibility of a data lake with the powerful analytics capabilities of Tableau. As a result, over 500 employees have been empowered to self-serve their own day-to-day analytics needs, while time to insight has been cut by 70%, leading to faster and more accurate business intelligence across the company. Centralizing all data and analytics through a single platform has also allowed Uniper to eliminate the use of multiple different databases and tools, saving over €1 million in 2018 alone.
We spent a lot of time looking at all the leading solutions on the market from vendors such as SAP, IBM and Oracle. In the end, Tableau’s powerful visualization capabilities, seamless integration and ease of use made it the top choice in nearly every category.
Using Tableau, key teams can pull data, conduct high quality analytics and create visual dashboards in the timeframe that suits them, not somebody else.
With Tableau, every trader can generate their own earnings report at 5:30pm each day via Tableau Mobile, giving them near real-time feedback as soon as the markets close.
New centralized approach to data and analytics saving over €1 million per year
Moving to a centralized data and analytics model has not only simplified processes and improved data quality, it has also created significant cost savings.
“Our new approach has helped us eliminate data silos from across the business, which were costing us money and preventing us from seeing the full picture,” says Rene. “With all data now stored in our data lake and visualized in Tableau, we’ve already been able to eliminate five legacy data systems and tools that we no longer need, saving us €1 million.”
Over 30 different departments within Uniper now use Tableau for all of their analytics and reporting, including IT, risk management, trading, generation, purchasing, selling and procurement.
“In the last year alone, we’ve connected more than 120 data sources to our lake, all of which can now be accessed and analyzed directly in Tableau by the departments that need them,” says Rene. “The ability to do everything via a single, scalable tool has enabled the company to truly unlock the hidden value in their data for the first time, which was impossible to do just a few years ago.”
