EV charging regulations in Germany: what Stadtwerke need to know

Disclaimer: This article provides general, non-exhaustive information and is not legal advice. The applicable requirements depend on the charge point, commissioning date, site-access model, legal entity, hardware, billing model, and role of the operator.

En bref :

• Stadtwerke have a strong starting position because of their local presence and energy expertise.
• The charging business introduces new operational and commercial responsibilities.
• The applicable rules depend on the site, commissioning date, power rating, legal entity and billing model.
• A compliant charging service needs connected processes, not isolated legal checks.
• The article explains the main frameworks and their practical implications.

For many Stadtwerke, offering EV charging is a natural extension of their role in local energy and mobility. They already understand electricity, infrastructure, and customer service. They are also close to the communities where charging demand is growing.

But running an EV charging service involves more than installing charge points. A Stadtwerke may need to manage public-access requirements, ad-hoc payments, price transparency, legally compliant metering, grid connections, live infrastructure data, roaming, customer support and the relationship between regulated and competitive activities.

The result is a regulatory landscape that reaches from the charging station to the backend, the invoice, and the customer-service team.

1. The short version: the regulatory stack behind EV charging in Germany

For public EV charging in Germany, the core compliance bundle is:

AFIR + the Ladesäulenverordnung + Eichrecht + EnWG and grid rules + consumer, payment, and data requirements.

These frameworks do not all apply in the same way to every charge point. The first step is to understand the operating model behind each site.

• AFIR: sets EU-wide requirements for public charging, including ad-hoc access, payment, price transparency and infrastructure data.
• Ladesäulenverordnung: provides German requirements for publicly accessible charge points, including notification and technical compliance processes.
• Eichrecht: governs the measurement and billing chain where customers are charged based on measured electricity.
• EnWG and grid rules: affect energy roles, grid connections, controllability and the separation of regulated and competitive activities.
• Consumer and payment rules: shape how prices, payment options, contracts and customer information are presented.
• Data rules: require accurate, timely, and accessible information about public charging infrastructure.
• Local and adjacent rules: may include GEIG, construction permissions, electrical safety, accessibility, data protection and cybersecurity requirements.

The regulatory stack at a glance-Stadtwerke

The important point is that these frameworks overlap. A single charging session can involve the charger, the meter, the backend, the payment provider, the invoice, the roaming partner and the public data record.

That is why the next question matters so much: which charge points are actually public?

Public or private? Why site classification comes first

Before choosing a payment flow or registering a charge point, a Stadtwerke needs to establish whether the site is publicly accessible. This is not determined only by who owns the land. A charge point on private property can still be public if the location is open to the general public.

A supermarket car park, customer car park, or public parking garage may therefore fall within the public-charging framework. A workplace charger restricted to a defined group of employees may be treated differently.

• Public accessibility is about practical access, not simply land ownership.
• A charge point can be public even when it is located on private land.
• A restricted-access site needs a clear definition of the eligible user group.
• Classification should be recorded per site and per charge point where necessary.
• The classification affects payment, pricing, registration, data reporting and customer-access obligations.
• A site can change classification over time, creating a need for controlled change management.

The Bundesnetzagentur distinguishes publicly accessible charge points from points reserved for private use or a defined group of users. It also states that there is no general obligation to make a charge point public. (Source: bundesnetzagentur)

Classifying charging sites

For Stadtwerke, site classification should not be a one-off legal decision hidden in a project file. It should be part of the charging asset record, because it influences the processes and data that follow.

2. AFIR: the customer-facing rules for public charging

The Alternative Fuels Infrastructure Regulation, or AFIR, is the central European framework for many public-charging requirements. It has applied since 13 April 2024 and sets requirements around access, payment, and price transparency at publicly accessible charge points.

For a Stadtwerke, AFIR is not only a regulation for charger manufacturers. It affects the complete customer journey, from finding a charge point to paying for a session and receiving a receipt.

Ad-hoc charging without a long-term contract

A driver should not need to become a long-term customer before being able to charge at a public point. This is the practical meaning of ad-hoc charging: the customer can start a session and pay without first entering into a continuing contract.

• Drivers must generally be able to charge without first signing a long-term contract.
• An app account, roaming contract or eMSP relationship can remain available as an additional option.
• A contract-based journey cannot automatically replace the required ad-hoc option.
• The ad-hoc journey needs to work without unnecessary registration barriers.
• The payment flow should be tested on the charger, in the browser and on mobile devices.

For a Stadtwerke, this creates a design question rather than a single hardware question: how can contract-based charging, roaming and ad-hoc payment work alongside one another without confusing the customer?

Payment options

• Payment terminals and contactless payment can support the required customer journey.
• Secure internet-based payment can be used in relevant cases.
• QR-code-enabled payment may form part of the payment journey, especially for lower-power points, where the full requirements are met.
• Apps and roaming contracts can provide convenience for returning customers.
• Payment and authentication options need to be consistent with the power category and commissioning date.
• The payment journey should not depend on an unverified assumption that every driver has the same app or contract.

The Bundesnetzagentur identifies card readers, NFC, and secure internet-based payment instruments among possible payment mechanisms and states that payment must be accessible without prior registration.

Price transparency before charging begins

• The customer must know the applicable ad-hoc price before starting the session.
• For public points of 50 kW or more, the ad-hoc price per kWh and any occupancy fee must be shown clearly.
• For points below 50 kW, relevant price components must be clearly and easily available.
• Pricing information must be understandable across the charger, payment page, app and receipt.
• The backend must apply the intended price consistently across direct and roaming sessions.

AFIR requires public charging operators to make relevant ad-hoc pricing available before a session begins. The requirements differ depending on whether the point is below or above the 50 kW threshold.

AFIR requirement to operational task

AFIR therefore reaches beyond the charger. It affects tariff configuration, payment providers, customer interfaces, roaming logic, receipts and the data held in the charging backend.

3. The Ladesäulenverordnung: technical requirements and registration

AFIR is not the only framework that matters. Germany’s Ladesäulenverordnung, or LSV, remains important for publicly accessible charge points, particularly for technical requirements and the notification process.

Many of the operational requirements for newer public points now come directly from AFIR, but the LSV remains part of the compliance framework that a Stadtwerke needs to manage.

• Public charge points must meet applicable technical safety requirements.
• Operators must electronically notify the commissioning and decommissioning of relevant points.
• Operator changes also need to be recorded.
• Existing points becoming public can trigger notification and compliance requirements.
• The regulator can request evidence of technical compliance.
• Non-compliant points may need to be retrofitted or may be prohibited from operating.
• Commissioning date matters because older points may be subject to different transitional rules.

The current LSV requires electronic notification of commissioning, decommissioning, and operator changes. It also allows the regulator to request evidence and require retrofitting where applicable requirements are not met.

4. Eichrecht: why charging billing is a complete data-chain problem

In Germany, billing for measured electricity brings the measurement and verification framework, commonly known as Eichrecht, into focus. For a Stadtwerke, this means that charging compliance does not stop at installing an approved meter.

The relevant question is whether the complete chain from measurement to invoice remains accurate, traceable, and verifiable.

• A compliant meter is necessary but not sufficient on its own.
• The measured value needs to remain linked to the correct charging session.
• Relevant measurement data must be protected against unauthorised alteration.
• The backend must preserve the information needed to support customer verification.
• The invoice or receipt needs to reflect the legally relevant measurement record.
• Public keys, signed values and transparency information may form part of the verification process.
• Roaming, tariff calculations and customer reimbursements should not break the measurement chain.
• Dispute handling requires reliable access to historical transaction and meter data.

The German measurement and verification framework focuses on measurement accuracy, traceability and verifiability. The compliance risk can therefore sit in the system behind the meter as well as in the meter itself. (Source: neleso; gesetze-im-internet)

This is why Eichrecht should be assessed across the hardware, firmware, backend, invoice, and customer-transparency layers. A charging platform can support that operating chain, but the final legal assessment depends on the complete setup.

5. EnWG, grid operations, and the special position of Stadtwerke

Stadtwerke often operate across several energy and mobility roles. A group may include an electricity supplier, a distribution system operator, an e-mobility company, and a charging business. Those roles may be closely connected commercially, but they do not carry identical legal responsibilities.

The operating structure therefore matters as much as the charging hardware.

When the Stadtwerke group also includes a distribution system operator (DSO)

• Distribution system operators are subject to restrictions around public charge-point activities.
• Section 7c EnWG provides a specific framework for the ownership, development, management, or operation of public charge points by DSOs.
• Exceptions can apply in cases of regional market failure, subject to the relevant process and approval.
• Group structure, internal services, procurement and cost allocation may need careful review.
• A regulated network business and a competitive charging business should not be treated as interchangeable activities.

Under Section 7c EnWG, electricity distribution system operators are generally restricted from owning, developing, managing or operating public charge points, subject to the statutory framework and possible exceptions. (Source: gesetze-im-internet)

Grid connection, capacity, and load management

• Public charging projects need a grid connection assessment.
• The available connection capacity can affect the number, power and operating profile of charge points.
• High-power hubs may require a different connection level and additional technical planning.
• Load management can help align charging demand with available capacity.
• Section 14a EnWG is particularly relevant to applicable controllable consumption installations, especially private EV charging installations.
• The application of grid-control rules should be assessed for the specific installation and connection arrangement.

The Bundesnetzagentur identifies private EV charging installations as typical examples of controllable consumption facilities under the Section 14a framework. The treatment of a particular charging installation should not be assumed without checking its technical and legal classification. (Source: bundesnetzagentur)

EV charging roles and responsabilities

For Stadtwerke, regulatory design and operating-model design are closely connected. Before selecting technology, the organisation should decide which entity does what and how those responsibilities will be kept separate, connected, or outsourced.

6. Charging data, the Mobilithek, and DATEX II

AFIR is not only about how drivers pay. It also makes charging infrastructure data part of the public operating model.

Operators of publicly accessible charge points need to make certain static and dynamic data available through the relevant national access point. In Germany, this is connected to the Mobilithek.

• Data obligations apply to publicly accessible charging infrastructure.
• Static data can include location, connector type, number of connections, operating hours and vehicle compatibility.
• Dynamic data can include availability, occupancy and operational status.
• Data must be provided free of charge and on a non-discriminatory basis where the relevant AFIR requirements apply.
• Data must be accurate and maintained when infrastructure changes.
• From 14 April 2026, DATEX II became the relevant standardised format for this data provision.
• The CPO backend needs a reliable source of truth for site, connector and status data.

For public charging operators, data quality is part of the service and part of the compliance model.

7. From regulation to operation: what a Stadtwerke needs its platform to manage

The practical question for a Stadtwerke is not only, “Which rules apply?” It is also, “Can our operating model apply those rules consistently across every site, session and customer interaction?”

A charging platform should help bring the relevant operational data and processes together without replacing legal advice or compliant hardware.

Regulation to operational capability

• Use one controlled source of truth for sites, connectors and operational status.
• Connect charger data with tariff, payment and customer-service processes.
• Preserve the data needed for billing, dispute handling and compliance evidence.
• Make public and roaming transactions visible to the teams responsible for support and finance.
• Support APIs and reporting requirements without creating duplicate manual records.
• Keep the operating model flexible enough for different site types and legal entities.
• Treat compliance-related data as operational data that needs ownership, validation and maintenance.

Last Mile Solutions supports the operational layer behind an EV charging business. For a Stadtwerke, that can mean connecting charging infrastructure, transactions, tariffs, roaming, customer access and operational data in one environment. The right setup depends on the organisation’s legal structure, hardware, commercial model and compliance requirements.

The goal is not to add another isolated compliance tool. It is to create an operating model in which charging, billing, customer access, data and support processes work together from the start.

Build compliance into the charging business from the beginning

For Stadtwerke, the regulatory landscape around EV charging can look complex because it spans several layers at once. AFIR shapes the public customer journey. The Ladesäulenverordnung creates German notification and technical obligations. Eichrecht reaches into measurement, data and billing. EnWG affects the role of the operator, the relationship with the grid and the separation of regulated and competitive activities.

The common thread is operational: every requirement needs to work in the systems and processes that run the charging business.

• Public EV charging is not only an infrastructure project.
• The legal entity and operating model should be defined before the platform architecture.
• Asset data, pricing, payment, metering, billing, grid management and customer service need to connect.
• A platform can support consistent processes and data flows, but it does not replace legal advice or compliant hardware.
• Stadtwerke should choose technology that can support their intended commercial model and future growth.
