Heat grid tariff checker

The ACM determines the maximum amount a heat supplier can charge for heat and for renting a connection. Suppliers may not charge more than these maximum amounts. The maximum rate may differ for each connection, depending, for example, on whether only heat is supplied or also cold, and whether the heat is used for heating or also for hot water.

Goal and impact

The algorithm was developed to investigate whether heat suppliers are not overcharging consumers. If there appears to be overcharging, this is first investigated further. If it turns out that there are indeed overcharges, the supplier can be held to account.


The purpose of the algorithm is to ensure fair tariffs. Citizens notice this by helping to keep energy bills fair. Heat suppliers may come into contact with it if their tariff structure is scrutinised.

Considerations

Using the algorithm saves a lot of time. The algorithm immediately alerts you to potentially excessive rates, without having to calculate everything by hand.

Human intervention

The results from the algorithm are checked manually through a four-eye principle before a licensed party is challenged on tariffs.

Risk management

The results from the algorithm are checked manually through a four-eye principle before a licensed party is challenged on tariffs.

Legal basis

The Heat Act

Operations

Data

Tariffs for heat network connections in various categories

Technical design

This algorithm checks per connection whether the tariffs are within the maximum tariffs. So for each set of supplied data, it finds out whether or not they are above the maximum. For tariffs that fall above the maximum, these are additionally checked manually to examine whether the tariff actually falls above the maximum.

  • Based on, among other things, the so-called credit rating, or creditworthiness of a party, a limit is calculated, indicating the maximum amount that can be lent to a counterparty (e.g. a bank).

  • A person in debt may face attachment of income. But there should always be a minimum amount left to live on. This is called the attachment-free amount. The algorithm (which consists of a set of calculation rules) helps calculate the debtor's attachment-free amount automatically as much as possible.

  • The ACM monitors the financial position of licensed suppliers. Based on information suppliers submit to the ACM, the ACM performs some simple calculations to determine various financial ratios. Partly based on the results, it determines which suppliers the ACM will prioritise when assessing all the information provided.

  • This algorithm assesses the financial position of licensed energy suppliers. It looks at their energy purchases and how well they have hedged supply obligations. The ACM calculates stress scenarios to see whether they can still meet their supply obligations for gas and electricity even then.
