Uniper’s supplier portal

We are a project intensive company with a strong customer focus that continually strives for improvement. We set high standards for ourselves and our suppliers and all of our suppliers are carefully selected. We work together to ensure that our projects are implemented on time and at the right cost. Our suppliers are important to us and critical to our success. Our ambition is that we work together to add value to our organization and ultimately to our customers.

Our procurement activities are decentralized into our various companies. We strive to coordinate the goods and services purchased by our subsidiaries into our corporate categories. Every year we buy goods and services on a large scale and our wide purchasing requirements range from office supplies to water turbines.

As a supplier to Uniper, you become part of us and our large network of business opportunities within the company. At the same time we expect our suppliers to give us the best possible total cost of ownership and to actively collaborate with us to improve and contribute to a long-term business relationship beneficial for both parties.

We welcome new and existing suppliers to Uniper’s supplier portal. Here you can read more about what is in demand at Uniper, the requirements and prerequisites we have, and how you can participate in our tenders.

Procurement System


Within Uniper we use the eSourcing tool SynerTrade, where we conduct an increasing amount of webbased tenders. By using this tool, the flow of information between Uniper and our suppliers in connection with tenders is simplified and everyone involved gets a good overview.

If you are invited to an eTender, you will receive login details and a weblink via email. You will also receive a welcome email from the Uniper purchaser before the tender starts.

In SynerTrade, suppliers can:

  • Choose whether or not to participate in a tender
  • See all eTenders they are participating in
  • Download attachments and requests for information/quotations/proposals
  • Submit offers, attach documents and leave comments
  • Change and add contact details and users within their own organizations

Contact the Uniper purchaser if you have further questions about eTenders in SynerTrade.
