Billing data: the best solutions for allocating energy costs
Energy management is becoming increasingly complex.
Organizations deal with multiple sites, dynamic tariffs, consumption data from different sources and growing reporting requirements. As a result, allocating energy costs to tenants, residents or departments is no longer as simple as it seems.
The key to a fair and efficient system? Billing data – also known as consumption data or energy data.
This article explains what billing data is, how it works, why it’s essential for transparent cost allocation, and how smart digital tools simplify the process.
What exactly is billing data?
Billing data consists of measured energy values used to calculate and allocate consumption and related costs correctly.
It includes:
- Consumption data for electricity, gas, heat or water
- Tariffs per connection type or time period
- Any surcharges or fixed costs
- Distribution keys between tenants or departments
In other words: billing data translates raw measurement data into usable billing information.
Without reliable billing data, energy costs cannot be allocated fairly or accurately.
Why is billing data important?
1. Transparency for Users
Consumers and tenants want to know what they’re paying and how their costs are calculated. Accurate billing data provides this insight — for instance, through dashboards or monthly overviews.
2. Fair Cost Allocation
In multi-tenant buildings or heat networks, billing data makes it possible to assign usage fairly. Everyone pays for what they actually consume.
3. Time Savings and Fewer Errors
Automated billing data processing eliminates manual data entry and calculation errors — saving time in administration and improving accuracy.
4. Compliance and Audit Trail
Energy regulations increasingly demand transparency. Reliable billing data supports compliance with frameworks such as the Heat Act, EED and CSRD.
How is billing data collected?
Billing data is created by collecting and combining measurement data that records on-site energy consumption.
That data can come from various sources, including:
- Smart meters for electricity, gas, heat and water
- Submeters that measure consumption per apartment, system or department
- Energy management systems (EMS) that consolidate all data centrally
In the past, this information was often fragmented across multiple systems.
Today, a platform like Aurum EnergyGrip connects everything — automatically validating raw measurement data, correcting errors, and converting it into billing-ready datasets.
The result: one reliable data source that not only shows consumption clearly, but also links it directly to cost structures, contracts and user information.
Thanks to this level of data accuracy, Aurum’s data is already used as the basis for official billing processes by heat and energy suppliers — demonstrating how essential well-validated consumption data is for fair and transparent energy costs.

From measurement data to billing: How it works in practice
- Data Collection
All relevant measurement points (for electricity, heat or water) are automatically read out. - Validation
Data is checked for accuracy — missing values, duplicates or measurement errors are automatically detected and corrected. - Tariff Linking
The validated data is connected to applicable tariffs or internal allocation models. - Billing or Cost Allocation
The calculated amounts are automatically assigned to users or cost centers and can be exported directly into accounting or ERP systems.
Who relies on billing data?
1. Property managers and housing associations
Essential for correctly allocating service charges and energy usage among tenants.
2. Energy companies and heat operators
Billing data ensures accurate invoices and transparent communication with end users.
3. Municipalities and collective projects
In local heat networks or solar initiatives, billing data allows costs to be distributed fairly among participating buildings or neighborhoods.
4. Multi-Site businesses
By connecting billing data to an EMS, organizations gain insight into energy consumption per site, department or process — supporting both cost control and sustainability goals.
The future: Automation and integration
The future of billing data lies in full automation.
Thanks to API integrations between metering systems, EMS platforms and accounting software, manual work is rapidly disappearing.
At the same time, real-time visibility is becoming increasingly important — not just invoicing after the fact, but continuous monitoring and optimization.
This makes billing data a core component of strategic energy management, not merely an administrative tool.
Control energy costs with reliable data
Whether you’re a heat supplier, property manager or large organization — without reliable billing data, there can be no fair or transparent cost allocation.
By using smart meters, centralized monitoring and automated data processing, you gain control over both energy and cost.
Billing data then becomes more than an administrative necessity — it becomes a foundation for efficient, sustainable energy operations.
