How do we ensure continuity in an iconic stadium when the electrical load changes dramatically? HyTEPS combines in-depth measurements with advanced simulations to ensure a flawless transition to sustainable LED lighting at De Kuip. We eliminate technical uncertainty and guarantee a stable installation so that the focus can remain on the sport and the supporters.
Stadion Feijenoord is taking a crucial step in sustainability by switching to LED lighting in the four iconic lighting columns and the roof edge. Although LED luminaires offer significant advantages in terms of lifetime and energy consumption, they also introduce complex challenges within the electrical installation.
Large quantities of LED drivers can lead to harmonic contamination, high inrush currents and unforeseen load on the neutral conductor. For a high-profile venue like De Kuip, which hosts large-scale concerts and congresses in addition to football matches, the uncertainty about the impact of these changes is a critical risk. After all, a production stop or failure during a live broadcast has huge financial and reputational consequences.

To ensure stability, our engineers perform an in-depth analysis that goes beyond a standard measurement. We start with a baseline measurement during a competition scenario, because the installation only shows true Power Quality dynamics at full load. With continuous waveform recording, we capture every detail, which forms the basis for a highly accurate simulation model.
By thoroughly analysing the specific characteristics of new luminaires - such as harmonic current and inrush currents - we validate the design in advance. We examine aspects such as Electromagnetic Compatibility(EMC) and supraharmonics to ensure that protective devices do not trip unwanted. This proactive approach translates complex data into the assurance that the installation will operate fault-free even under severe conditions.
Based on the analysis, our engineers optimise the installation. A crucial part was lowering the voltage in cooperation with the grid operator to meet the specific requirements of the new LED luminaires. Through these proactive adjustments and close monitoring during installation, we reduce technical risks to an absolute minimum.
The final validation measurement proves that the installation performs exactly as designed. For Stadion Feijenoord, this means a successful transition to sustainable lighting without concessions to operational reliability. With a validated model and a clear final report, we offer the guarantee that the risk of malfunctions is low and continuity at De Kuip remains guaranteed.

Do you have doubts about the Power Quality within your installation or are you on the eve of a major technical change? Don't wait for invisible problems to become visible in the form of outages or damage.
