For many businesses, energy costs are one of the largest recurring expenses. Yet, surprisingly few know if they are actually paying the correct amount.
The reason is simple: Electricity and grid tariffs have become so complex that invoices are practically impossible to verify.
The Complexity Behind the Energy Invoice
An energy invoice isn't just a single price per kWh.
It is the result of multiple layers of calculations:
- Electricity contracts with various pricing models (spot, fixed-price, variable)
- Grid tariffs with demand charges, energy charges, and fixed costs
- Time-differentiated rates (hourly, daily, seasonal)
- Optional add-ons like reactive power
Furthermore, these factors vary:
- Between grid companies
- Between geographic regions
- Between different customer types
This means that two seemingly identical locations can have entirely different cost structures.
The Challenge: Does the Invoice Match Reality?
The central issue is simple:
Does the invoiced amount match what you are actually supposed to pay?
To answer this, you must:
- Have access to detailed metering data
- Know the tariff model of the relevant grid company
- Understand how the electricity contract is structured
- Recreate the entire cost calculation
In practice, this is extremely difficult to do manually.
As a result, many businesses:
- Blindly trust their invoices
- Lack the tools for verification
- Fail to detect discrepancies
Mistakes Happen—and They Can Be Costly
Billing errors in the energy market are not uncommon.
They can be caused by:
- Errors in the tariff data
- Incorrect classification of a customer or facility
- Missing or incorrect handling of demand charges
- Discrepancies in metering data or the basis for calculation
Often, the errors are small on a monthly basis—but over time, they can add up to significant amounts.
allmy.energy customers have uncovered such discrepancies and received refunds totaling millions.
Why Isn't This Discovered Sooner?
There are several reasons:
- Invoices lack transparency
- Calculations are complex and variable
- Data is fragmented across different systems
- Manual verification is time-consuming and not scalable
In practice, this means many businesses lack real control over their energy costs.
From Invoice-Based Checking to Data-Driven Verification
To truly validate an invoice, you must shift your approach:
Instead of just reading the invoice, you must reproduce it.
This involves:
- Collecting historical metering data
- Modeling the current tariff structure
- Calculating expected costs
- Comparing the result against the invoiced amount
When done systematically, this makes it possible to:
- Uncover discrepancies
- Document errors
- Claim refunds
- Establish ongoing monitoring
allmy.energy: Verifying Energy Costs in Practice
allmy.energy is designed to make this process manageable.
The platform collects and models:
- Metering data from facilities
- Electricity prices and contract structures
- Grid tariffs from all Norwegian grid companies
This enables you to:
- Calculate what you should actually be paying
- Compare this directly with your invoice
- Identify discrepancies down to the finest detail
The result is a completely new level of control—without the manual complexity.
Continuous Monitoring—Not Just a One-Time Check
The greatest value isn't just in finding historical errors.
By establishing ongoing monitoring, businesses can:
- Catch discrepancies as they occur
- Reduce the risk of future errors
- Improve their basis for decision-making
- Create predictability in energy costs
Conclusion
The energy invoice is not necessarily the final word—it is the result of complex calculations that may contain errors.
The question is not whether discrepancies exist—but whether you have the tools to find them.
With the right data foundation and modeling, it is entirely possible to take control.
allmy.energy makes it possible.
