Control of the network operator, transformer losses, measurement concept testing and checking of feed-in and purchased electricity bills
Maximum transparency and precision – protect your company from hidden costs
Billing for electricity, both when it is purchased and when it is fed into the grid, is often a complex and opaque process. Incorrect billing or inaccurate measurements can cause significant additional costs that often go undetected. With our service for checking grid operator billing, transformer loss calculation, measurement concept testing and checking feed-in and purchased electricity bills, you get full transparency and can ensure that every kilowatt hour is billed correctly - thus protecting your company from unnecessary costs.
Why you should check your network operator's billing
Many companies rely on the accuracy of grid operator billing without knowing that errors can occur in the measurement, calculation or allocation of electricity quantities. These errors can lead to:
Excessive costs due to incorrect calculations of network or consumption fees,
undetected feed-in losses, where the actual amount of electricity fed into the grid is billed at a lower rate,
and lead to incorrect bookings when determining network charges and other fees.
Our grid operator billing control service analyses all the details of your bills and ensures that you only pay for actual consumption and correct feed-in.
Measurement concept testing – Make sure your measurements are correct
The metering concept is the backbone of any accurate energy billing. An inappropriate or faulty metering concept can lead to your energy consumption or feed-in quantities being recorded incorrectly. This not only leads to incorrect billing, but can also mean that important energy flows are not measured at all.
Our measurement concept review includes: Checking the measuring devices used: Are your meters and measuring devices up to the requirements of your business and your energy infrastructure? We ensure that all relevant consumption and feed-in values are recorded correctly. Analysis of the measuring point placement: Are the measuring points optimally arranged to record all relevant energy data precisely? A poor measurement concept can lead to some areas of your energy consumption being under- or over-recorded. Checking the measurement accuracy: Are your meters sufficiently calibrated and state-of-the-art? Even small inaccuracies can add up to significant costs in the long term. An optimized measurement concept gives you the security that your energy flows are recorded correctly and that no inaccurate measurements falsify your bills.
Checking feed-in and purchase electricity bills – Avoid expensive deviations
Errors in feed-in or purchased electricity billing can have significant financial implications, especially for companies with high electricity consumption or large amounts of self-generated electricity. We offer a comprehensive audit of your feed-in and purchased electricity bills to ensure that you do not have any undetected discrepancies or incorrect calculations in your bills.
Our billing review service includes: Checking feed-in values: Do the feed-in values stated in the bills match the amount of electricity actually fed in? Discrepancies often occur that are due to incorrect measurements or billing errors. Analysing electricity bills: Has the electricity consumption shown in the bill been recorded and calculated correctly? We ensure that the electricity consumption billed reflects your actual consumption. Checking network costs and fees: Have the network fees been calculated correctly? Flat-rate network costs are often used that are not tailored to individual energy consumption or the actual network loads. By thoroughly checking your bills, unnecessary additional payments can be avoided and potential sources of error can be discovered early on.
Detect and reduce transformer losses – Increase the efficiency of your energy infrastructure
Transformers are central components of energy distribution in many companies. They ensure that electrical energy is converted between different voltage levels and can thus be used efficiently. But transformers also cause invisible losses that often go unnoticed. These so-called no-load and load losses can lead to significant costs in the long term. In order to make your energy infrastructure more efficient and reduce your operating costs, it is crucial to identify these losses and minimize them in a targeted manner.
What are transformer losses? Transformer losses occur during the normal operation of a transformer, both when it is in operation (load losses) and when it is running at idle (no-load losses). Both types of losses can result in significant wastage of energy: No-load losses: These losses occur when the transformer consumes energy when there is no load or only a small load. Even when no machinery or equipment is active, the transformer causes energy losses due to magnetization processes in its core. Load losses: These losses occur when electrical energy is fed into or drawn from the grid through the transformer. They are caused by the resistance of the copper windings and other electrical processes within the transformer. Both types of losses are often invisible because they do not immediately lead to a sudden increase in energy costs. Instead, they accumulate over time and contribute to high operating costs without being easily noticeable.
Why is it important to minimize transformer losses? Transformer losses are a major factor in a company's overall energy costs. Without targeted analysis and optimization, these losses can cause several thousand euros in additional costs every year - costs that can be avoided by targeted optimization of transformer performance. In addition, reducing transformer losses leads to: Increased efficiency: Fewer losses mean that more of the energy supplied is actually used instead of wasted. Longer transformer life: Transformers that work more efficiently are less stressed, which extends their life and reduces maintenance requirements. Sustainability: Reducing energy losses not only helps reduce costs, but also contributes to environmental protection by reducing energy consumption and reducing CO₂ emissions.
How we minimize transformer losses Our transformer loss minimization service includes a comprehensive analysis and optimization of your transformer infrastructure. Here are the steps we go through: 1. Detailed analysis of no-load and load losses We analyze your transformers in terms of no-load and load losses. To do this, we use special measuring devices that accurately record the power loss of your transformers and show in which operating states the greatest losses occur. 2. Review of transformer dimensioning Many companies operate transformers that are oversized or undersized for their actual load. Incorrect dimensioning leads to either unnecessary no-load losses (with oversized transformers) or high load losses (with undersized transformers). We check whether the power capacity of your transformers is optimally adapted to your energy needs. 3. Optimization of transformer utilization By correctly adjusting operating times and specifically controlling the energy flow, transformers can work more efficiently. This can be done, for example, by using intelligent control systems such as the electricity price manager, which distributes energy consumption to the cheapest times and thus avoids unnecessary loads. 4. Replacement of outdated transformers Transformers that are over 20 years old usually work less efficiently than modern equipment. When transformers reach the end of their service life, more modern, efficient models can provide significant savings. We analyze when replacement makes economic sense and offer you tailored recommendations for new, energy-efficient transformers. 5. Monitoring and continuous monitoring After optimizing your transformer performance, we offer continuous monitoring of transformer losses. This way we can ensure that losses remain permanently minimized and your transformers operate at maximum efficiency.

Q&A – Frequently asked questions about electricity billing and incorrect billing
1. What are the most common errors in electricity bills? The most common errors in electricity bills concern: Incorrect consumption values: Bills are often based on estimates if no current meter readings have been submitted, which can lead to incorrect costs. Incorrect tariffs: Some customers are classified in the wrong tariff classes, which leads to higher prices per kilowatt hour. Incorrect network charges: Network charges can often be calculated incorrectly, especially in complex distribution networks or industrial consumers. Missing feed-in values: For photovoltaic or cogeneration plant operators, it can happen that the actual amount of electricity fed in is not recorded correctly.
2. How can I check if my electricity bill is correct? To check if your electricity bill is correct, you should: Compare meter readings: Check whether the meter readings shown in the bill match those on your meter. Check contract details: Make sure that the prices per kWh, basic fees and network charges shown match your contract. Analyze consumption behavior: Compare your consumption with previous years or with similar households or businesses to identify unusually large deviations.
3. What should I do if my electricity bill is wrong? If you suspect your electricity bill is wrong, you should: Check the meter reading and compare it with the billing information. Contact the electricity provider to report the error and request a correction. Have documents ready, such as contracts, previous bills and meter readings, to support your position. Make payments on time: Pay the undisputed part of the bill to avoid late payment fees.
4. What rights do I have if I receive an incorrect bill? You have the right to: Correction of the bill: Your energy supplier must prove that the bill is correct and correct any errors. Refund of overpaid amounts: If you have paid too much due to an incorrect bill, you are entitled to a refund. Objection: You can object to the bill within the specified period and request a new calculation.
5. What is an estimated bill and when is it used? An estimated bill is created when the network operator or energy supplier does not receive current meter readings. This bill is based on estimated consumption values based on historical data or averages. Such estimates can be inaccurate and should be corrected with actual meter readings at the earliest opportunity.
6. Can I contest an estimated bill? Yes, you can contest an estimated bill. To do this, you should record your current meter reading and send it to the provider. The provider is obliged to recalculate the bill based on the actual values.
7. How do errors arise when billing photovoltaic and combined heat and power plants? The following errors can occur when billing PV systems and combined heat and power plants: Incorrect feed-in values: The amount of electricity actually fed into the grid is often not recorded or calculated correctly. Lack of compensation: The electricity fed into the grid may not be fully compensated or may be billed at the wrong rate. Unclear meter readings: In systems that measure both feed-in and self-consumption, discrepancies in the recording can occur.
8. What are typical errors in network charges? Typical errors in network charges are: Failure to take into account discounts for peak load management or reduced consumption during off-peak periods. Incorrect tariff classifications: Sometimes customers are classified in more expensive tariff classes even though they qualify for lower network charges. Excessive metering point charges: The fees for operating and maintaining metering points can be calculated incorrectly.
9. What can I do if the network charges are incorrect? If you suspect that the network charges in your bill have been calculated incorrectly, you should: Check the network charge structure: Check your classification and the applicable network charges in your network area. Compare with the contract: Make sure that the charges correspond to the contractually agreed tariffs. Contact the network operator: If there are any discrepancies, contact the network operator and request an explanation or correction.
10. What role does the measurement concept play in billing? The measurement concept is crucial for precise recording of electricity consumption and feed-in quantities. Faulty measurement concepts, such as incorrectly placed meters or inaccurate measuring devices, can lead to incorrect billing. Reviewing and optimizing the measurement concept can help to identify and correct deviations.
