Celebrating a major milestone: Successful completion of Systems Integration Testing (SIT) 

We're delighted to announce the successful completion of System Integration Testing (SIT), a significant milestone in our journey towards Market-wide Half-Hourly Settlement. 
 
SIT has been at the heart of testing the complex interactions across the industry, ensuring systems can integrate seamlessly and perform under real-world conditions. Over the course of this phase, participants have collaborated closely with the Programme to validate functionality, resolve defects, and build confidence in the robustness of the end-to-end solution. 
 
The Programme extends its thanks to everyone who has contributed their time, expertise, and energy to make SIT a success. From technical leads and test teams to Programme managers and Programme Party Coordinators (PPC), your efforts have been critical in reaching this point. 
 
Together, we’ve proven what can be achieved through determination, collaboration, and shared commitment to delivering one of the most important industry change programmes in recent years.
