PLB Group was about to invest heavily in a battery storage system to cope with grid congestion and power constraints. Our engineers carried out a detailed Power Quality measurement and immediately discovered sufficient spare capacity in the existing installation. As a result, we achieved full operational reliability without unnecessary capital injections.
Industrial end-users are increasingly affected by grid congestion when taking or returning power. The consequences of these capacity problems range from power restrictions and voltage issues to long waiting times and heavy contractual penalties. PLB Group, a large company in the manufacturing industry, received the same independent advice from two external consultants. To smooth peaks and avoid overruns, the purchase of a large-scale battery storage system would be inevitable.
Before agreeing to this huge investment, the organisation sought assurance. There was a need for detailed insight into actual plant loads and the exact locations of any bottlenecks. In addition, the question was whether specific loads could be safely moved to another hall without exceeding limits. The aim was to establish conclusively whether a battery pack really was the only effective solution.

To provide a clear diagnosis, our engineers combined a contractual review with a thorough thermal and security analysis. We assessed the contracted transmission capacity based on 15-minute averages according to the GTV standard, in accordance with EN 50160. This analysis immediately showed whether there was actually a capacity overrun on the grid connection.
At the same time, we used one-second measurement data to analyse short-term spikes that can cause unwanted tripping of fuses and protection devices. This proactive two-track approach pinpointed the nature and origin of the spikes. It provided a complete and factual picture of both the system perspective and the behaviour of internal components.
The measurement results provided immediate assurance: all measured current values were well within the contractual limits. There was no structural overrun and the installation was even found to have ample spare capacity. Our engineers localised the actual internal bottlenecks and recommended the installation of a capacitor bank. This optimal reactive power compensation successfully reduces the apparent power (kVA) towards the active power (kW).
This data-driven implementation directly reduces grid and capacity costs and prevents cos φ penalties. Moreover, the measurement profiles showed that PLB Group could responsibly move specific activities to the targeted hall without creating new bottlenecks. Implementing these internal optimisations completely eliminated the need for a battery storage system and avoided an unnecessary investment of hundreds of thousands of euros.

A stable and cost-efficient installation starts with correct diagnostics. Avoid decisions based on assumptions and get actual insight into your capacity. Speak to an engineer to increase the operational reliability of your network.
