Taking Efficiency in Energy Trading to the Next Level – Norlys Energy Trading 🇩🇰
A Strong Validation of the Ecosystem Concept
In May 2021, Previse Systems and Fidectus have embarked on a partnership to connect Previse Coral with Fidectus’ GEN platform. The goal of course was and is to enable seamless post trade processing and full back-office automation, including electronic Confirmation (eCM) and Settlement Management (eSM).
The pilot customer, Norlys Energy Trading A/S, is very satisfied with the combined solution:
“The collaboration of Previse Systems and Fidectus and their plug-and-play integration allow us to have ETRM and eCM/eSM centralised in one solution, enabling full trade lifecycle automation in one unified workflow”, says Michelle Rønne, Head of Back Office at Norlys Energy Trading.
For Previse Systems, the collaboration with Fidectus represents a strong validation of the Ecosystem concept – the combination of best-of-breed platforms and specialised applications using modern technology and communication standards.
A Previse Systems Success Story – Norlys Energy Trading 🇩🇰
Michelle Rønne, Head of Back Office at Norlys Energy Trading, talks about how Previse Systems make her life easier
“Previse Systems rethink the way ETRM software is designed – they have built a software that actually supports today’s trading patterns” says Michelle Rønne, Head of Back Office at Norlys Energy Trading A/S.
“We have worked with other solutions in the past and those solutions are not geared to handle the number of trades we are doing today. Today’s solutions need to be designed for many small trades rather than a few big ones.
The Previse Coral solution is very data and event driven, so rather than spending human resources clicking around the system, the solution automates processes and allows us to only focus on exceptions.”
Michelle, thank you very much for taking the time to share some of your impressions and experiences with the Previse Coral software with us, and with other prospective customers of Previse Systems!
Michelle: I have already mentioned performance and automation. A further important point to note is definitely the flexibility of the solution, especially around defining workflows: we are able to configure the system around our processes instead of being limited to follow processes defined by the system. Previse Coral is incredibly generic here, it allows to fine-tune the workflows exactly as we need them, e.g. with features like the transition process and the partial locking of trades.
Can you elaborate a bit on that?
Historically my experience is that we end up spending a lot of time changing the tradebook or strategy on the trade. With the Previse partial locking we can decide exactly what back office needs to have locked for controlling and what is open for front office to change.
Does that also extend to settlement processes?
Well, Previse Coral is designed with a settle date and a clearing date which allows us to model all the special rules from the clearing houses along with the exchanges. We know when the trade can be controlled based on when it will be cleared. This allows us to automate those processes.
We all know how difficult it can be to ensure that all trades that need to be controlled and settled on a given day are handled, because of all of the special rules given by the clearing houses and exchanges. So instead of setting up a very complex filter or query (which is impossible to maintain) we can simply select by yesterday’s clearing and settle date and this gives us the definitive list of items to be processed.
Has event driven settlement automation supported you in optimizing your processes?
Yes, absolutely. Since settlement is the final process of the trade, the numbers are always affected by the data upstream and it happens that some of that data might be captured incorrectly. For example, the clearing broker could have a mistake on their side for the settlement date or a manually captured trade could be wrong. In such cases, we just correct the data on the trade and the settlement event engine triggers a re-settlement of the trade automatically – we can then just flip over to the Settlement screen after editing the trade, and the data is already updated and ready for settlement.
It’s amazing not to have to run a batch process or similar! You can just process the data much quicker than in other solutions I have worked with.

Norlys Energy Trading Goes Live on First Release of Core ETRM Platform


Zug, 12. May 2021: Previse Systems announced today that Norlys Energy Trading has successfully taken the first release of it new Core ETRM platform – based on ChorusLink, Previse Coral and the Coral Ecosystem – into production.
The primary goal of Release 1 is to support the trading of power and natural gas on EEX as well as Nasdaq OMX, with master data provided by ChorusLink and valuations run in Previse Coral. Release 2 will expand coverage to further instruments across additional European markets for gas and power.
Release 1 was delivered entirely remotely. A strong team spirit with a shared focus on the common goal ensured a smooth and timely completion.
About Norlys Energy Trading
Norlys Energy Trading A/S was founded in May 2020 and owned by Norlys Holding A/S and Eurowind Energy A/S The company is based in the Northern part of Denmark in the city of Aalborg.
We are in the process of building a solid and automatized organisation with an efficient platform for energy trading and aim to streamline the handling of renewable energy in both Denmark and the rest of Europe.
We strive to become one of the top European players in electricity and gas trading and to be one of the frontrunners of the green energy transition.
As the energy sector is getting “greener”, more complex than ever, and new solutions emerge everywhere, we have chosen to be an active part of and significant contributor to a sustainable future.
Allan Kaufmann, Head of IT Development at Norlys Energy Trading, said:
“We welcome the first deployment of our entire platform into production and can officially state that Norlys Energy Trading is now an operating trading company. This first go-live will probably be the largest and most important deployment we ever face since all our different systems and components (that together represent our world class trading platform) now are combined and running.
It´s quite amazing to see how much we have achieved working from home! We have established very close collaboration with our various counterparts and especially with Previse Systems, who have proven to be a very flexible and high performing partner.
We have started out strong and now we are increasing the pace. What a fantastic journey!”
Asbjørn Hansen, Managing Director at Previse Systems, said:
“At Previse Systems, we are very proud of this first result of our partnership with Norlys Energy Trading. Thanks to an efficient and close collaboration of the project teams – of course entirely remotely as mandated by the circumstances – we were able to not only fulfil a very demanding project schedule, but even to increase the project scope and deliver more functionality than originally planned.
We were able to demonstrate the strength of our concepts for example in the core success criteria of time to market and performance – the combination of our innovative data management approach with the utilisation of advanced Azure cloud services and the serverless technology provided by Microsoft allows new markets to be onboarded quickly and valuation runtime to be all but independent of the number of trades to be valued.
We are excited to support Norlys Energy Trading on their journey and look forward to a continuous stream of further successful releases over the coming months.”

During the course of our proof of concept, we had the opportunity to work closely with the highly experienced team of Norlys Energy Trading, and we are convinced our collaboration will be prime example of a total that becomes much more than the sum of its parts. I look forward to working with Norlys Energy Trading, and to benefitting from their drive to ensure that our solutions are the best in the market.”

European Energy joins ChorusLink for Next Generation Trade Data Management
Zug, 16. October 2020: ChorusLink announced today that European Energy A/S has successfully migrated to the ChorusLink common trade repository.
Using ChorusLink will allow European Energy to:
- streamline the management of all transaction data from its trading operations
- lay a robust foundation for highly performant availability of trade data in a standardized format
- benefit from a centrally maintained repository of commonly used master data
- continuously increase back office automation as its counterparties also join ChorusLink
Jonas Nihøj, Director of Energy Trading & PPA at European Energy, said:
“The main reason for choosing ChorusLink and Previse Coral was to get the solution today which will be the market leader tomorrow, to ensure we have the scalability and performance we need.
As our current production portfolio of 3 TWh per year is set to grow tenfold over the next 5 years, we were faced with either scaling manual processes or investing for the future. We know that our needs today will be vastly different from tomorrow.
With the ChorusLink / Previse solution, we will be in a position to implement technological advancements on-the-go via the App Store, and we will have a competitive advantage in the years to come. Other aspects important to us are to retain ownership of our data and the possibility to easily change App providers, if required, with minimum efforts and costs.
Drawing on the experience of implementing several different ETRM systems, I know it is crucial to have the right partner for the journey and the Previse team have consistently delivered on time and budget. Therefore, I am confident that they will be an enabler for us in the years to come, when we embark on our ambitious growth journey.”
