Why your contract power is often not the real limit

Grid congestion map

For technical managers, facility managers and installation managers, grid congestion is a daily reality that paralyses projects. You want to increase sustainability or start a new production line, but the grid is 'full'. Yet in practice, the grid operator's hard limit is often not the limit of your technical capabilities.

Our years of experience and hundreds of measurements at industries, hospitals and data centres reveal an important fact: hardly any installation uses its capacity 100% efficiently.

Active power vs. Apparent power (kW vs. kVA) Your connection (and the grid operator's bill) is often based on kVA (apparent power). This is the sum of the useful power (kW) running your machines, and the 'lost' power (kVAR) due to reactive current and harmonic contamination.

When your Power Quality is sub-optimal, you 'fill' your cables and transformers with this unusable power. As a result, you reach your contract limit, when in reality you could be running many more machines. This is a waste of your investment and inhibits your operations unnecessarily.

HyTEPS analyses this balance in detail. We ensure certainty in every kilowatt. By removing contamination, we literally create space on your existing cable.

Optimising your installation in three steps

Before installing hardware or recommending expensive modifications, we want to know exactly what is going on in your installation. Our engineers use a proven methodology to eliminate risks and guarantee maximum results.

Measurement and monitoring

Measurement and monitoring

Measuring is knowing. We install advanced Power Quality meters that map your entire installation, or specific descending fields. We don't just look at peak consumption, but analyse waveforms in depth. We bring harmonic pollution, voltage dips, imbalance and reactive current into razor-sharp focus. This answers the question: how much 'air' is left in your current connection?

Analyse and Simulate

Data without context is worthless. Our Engineers analyse measurement data and, if necessary, build a digital model of your installation. In this secure simulation environment, we test scenarios:

  • What happens to Power Quality when you add that new heat pump?
  • How many kVA will be released if we eliminate reactive current?
  • What is the effect of a battery on the harmonics present? This way, we avoid surprises and investments that do not solve the problem.

Solving and managing

Based on the facts and simulations, we implement the solution. This ranges from active filters that free up capacity to an EMS that switches smartly during peaks. The result: you stay within your contract capacity, avoid penalties and your installation runs more safely and efficiently.

Concrete techniques to bypass grid congestion

How exactly do we create that extra space? Depending on the diagnosis from our measurement, we deploy specific technologies to 'unload' your installation.

Harmonics reduction

Active filtering:

Modern, energy-efficient equipment such as LED lighting, EV chargers and AC drives cause harmonic pollution. These non-linear loads distort the sinusoidal form of the current. This causes additional heat generation (losses) and increases the so-called RMS current (the effective current value).

  • The result: overall power load is significantly reduced. In practice, we often see that this can free up 10% to 20% capacity on the existing transformer, purely by 'cleaning' the current.

Blind current compensation

Cos Phi Improvement:

Many inductive loads, such as motors and transformers, consume reactive current to build up magnetic fields. This stresses your infrastructure, but does not provide labour. A poor power factor (cosine phi < 0.85) means a significant portion of your contracted kVA space is lost.

  • The result: Power demand towards the grid operator drops immediately. You can connect more active machines (kW) to the same transformer.

Monitoring Engineers discuss Energy Management System (EMS) &amp; Peak Shaving

Energy Management System (EMS) & Peak Shaving

Sometimes average consumption is low, but peaks are too high for the connection. Grid congestion is often a problem of specific moments.

  • The solution: An intelligent Energy Management System (EMS) measures your consumption in real time at the main connection. Are you in danger of going over your contract power? Then the EMS can automatically temporarily scale down non-critical processes or, if present, let a battery step in (Peak Shaving).
  • The result: You flatten peaks and stay within the limits of your contract, keeping expansion possible.

Overcoming asymmetry and imbalance

In some cases, capacity is limited because the load is unevenly distributed among the three phases (L1, L2, L3). The most heavily loaded phase sets the limit and trips the main protection, while the other phases still have room.

  • The solution: our systems can redistribute energy between phases (Load Balancing).
  • The result: you once again make optimum use of the full capacity of your 3-phase connection.

Why a battery is not always the first step

The market is currently flooded with battery system providers (BESS) as the solution to grid congestion. "Install a battery and you are rid of the problem," is the common promise. While energy storage is a powerful tool, it is often a costly and sometimes even risky step as a starting point.

Why? Because you connect a battery to your existing installation. If that installation is internally contaminated by harmonics or struggling with voltage dips, you are introducing expensive power electronics into a 'sick' environment. This can lead to:

  • Resonance: The battery inverter will resonate with other equipment, leading to failure.
  • Accelerated wear: The life of your battery system decreases dramatically due to poor Power Quality.
  • Inefficiency: You need to buy a much larger (and more expensive) battery to compensate for losses.

At HyTEPS, therefore, the rule always applies: First optimise, then invest. We ensure that the basis - the Power Quality - is perfect. It often turns out after optimisation that a battery can be much smaller, or even not needed at all, to realise your expansion plans.

Frequently asked questions about grid congestion and solutions

Answer:

Grid congestion, simply put, is congestion on the power grid. At peak times, the demand for power (or the supply in case of feed-in) is greater than the cables and transformers can handle. As a result, grid operators refuse new connections or reinforcements to companies.

Answer:

Yes, to a certain extent. You cannot solve congestion on the public grid, but you can optimise your own 'vehicle'. By making your internal installation more efficient (improving power quality) and smoothing out peaks, you get more power from your existing connection.

Answer:

Not as a first step. A battery can handle peaks, but if your base plant is contaminated by harmonics, the battery inverter may fail, resonate or wear out faster. HyTEPS always recommends a measurement and simulation first.

Answer:

This varies by installation. In industrial environments with many motors and drives, we often see that 10% to 20% of capacity is 'lost' to reactive power and harmonics. Correcting this immediately frees up that space for useful load.

Answer:

Grid operators bill consumption in kWh, but limit connection capacity to current (A) and thus indirectly to kVA. You use kW as useful power. If the power factor is low (e.g. due to reactive current or harmonics), more kVA is needed for the same kW. As a result, you hit the connection limit faster.
By improving the power factor, you can use more kW within the same connection capacity, without increasing the connection load.

Answer:

You often do, but you may not be allowed to feed back (feed-in congestion). You must then use or store the generated energy directly yourself. An EMS is crucial here to ensure that you do not accidentally feed back to the grid.

Answer:

a. Removing contamination such as reactive power and harmonics eliminates the 'polluted' current that unnecessarily loads your cables. This creates physical space on your current connection for more IT equipment.

Answer:

Yes. Without measurement, you are guessing; you do not know whether your capacity problem is due to actual consumption or pollution. A measurement prevents you from investing in the wrong solutions (such as an overweight battery).

Answer:

Sure. We are the power quality specialist. We often work together with the customer's regular installer (E-installer) to carry out the measurements and install the solutions.
