Opoura’s engineering experts are introducing a new unit model engine to address one of the energy industry‘s rising challenges: more complex plants combined with stricter grid compliance requirements. With this advanced tool, manufacturers gain access to unit simulation models much faster than today, reducing the plant owners’ grid connection time.
SILKEBORG, DENMARK – October, 2025 – Opoura announces the launch of their new Unit Model Engine (UME), which is a specialized software engine designed to deliver unit simulation models faster and more accurately, with the aim of minimizing grid connection time for sites such as large data centers, district heating plants with e.g. large heat pumps, or energy storage facilities.
As grid requirements become increasingly complex, large power-producing and consuming plants are required to submit unit models that demonstrate the predictability and accuracy of each unit’s behavior in accordance with system operator standards.
This may not be a challenge for large, well-established manufacturers. However, as the market expands and new players and technologies, such as batteries, enter the market, the need for unit models becomes evident, as not all manufacturers have the internal resources to meet these requirements on their own. And that could potentially become a significant and costly affair for new plant projects.
Erik Bundgaard Poulsen, Commercial Director of Power Engineering at Opoura, explains:
"Without approved unit models, projects can stall, which is a costly affair. We have seen this happen across several projects, where delays in approvals have not only strained budgets but also pushed back critical grid connection timelines," says Erik Bundgaard Poulsen.
The challenge also grows as more plant owners begin to reassess their business models and embrace co-location, leading to more complex plants where simulation models must also account for increasingly fragmented technology mixes.
Opoura is tackling this challenge by offering its Unit Model Engine, a launch made possible by Opoura’s strengthened expertise in grid modeling, control, regulation, and the commercial development of energy-producing assets. Unit Model Engine provides compliant, high-quality unit simulation models – fast:
"We developed the Unit Model Engine to help customers stay ahead of regulatory changes, prevent costly delays, and avoid missing the opportunity to connect to the grid at all. The engine provides unit models that show the same dynamic behavior across all simulation tools. Besides this, the engine is developed to support compliance with any regulatory requirements that system operators deem necessary for future sites and components, reducing the overall risk in the process of grid connection," concludes Erik Bundgaard Poulsen.
