PV & BESS Assessor Augsburg — Technical Connection Requirements swa Netze

In our assessment projects for photovoltaic and battery storage systems in the greater Augsburg area, we regularly encounter questions regarding the technical connection requirements of swa Netze. Whether acceptance of a commercial PV system in the Augsburg-Sued industrial areas, defect assessment of an existing system in Lechhausen, or technical supervision of a medium-voltage connection in the Innovationspark — TAB conformity is always a central checkpoint in our assessments.

What are the special features of the Augsburg grid area?

swa Netze GmbH operates the power distribution grid in the Augsburg area serving approximately 300,000 inhabitants. The combination of old town locations with listed buildings and modern industrial areas in the south of the city leads to very different grid capacities. The municipal FKG subsidy program from Munich does not apply here — Augsburg has its own municipal climate protection programs.

Which standards apply to PV systems in the Augsburg grid area?

Standard	Scope	Relevance for PV
VDE-AR-N 4100	Technical connection rules low voltage	Mandatory — meter location, service entrance, protection concept
VDE-AR-N 4105	Generation systems on LV grid	Mandatory for PV ≤ 135 kW
VDE-AR-N 4110	Technical connection rules medium voltage	Mandatory for PV > 135 kW
Supplementary TAB swa Netze	Regional supplements	Grid operator-specific requirements
DIN VDE 0100-600	Initial verification of electrical installations	Mandatory inspection before commissioning

How does the PV system registration process work at swa Netze?

1. Engage a certified electrical contractor: Only registered installers may submit the registration (exception: balcony power plants).
2. Grid compatibility assessment: For systems from approx. 30 kWp, swa Netze checks the grid's absorption capacity.
3. Commissioning application: The installer submits data sheets, site plan, circuit diagram, and conformity certificates.
4. Prepare meter location: Must comply with VDE-AR-N 4100 and the supplementary TAB.
5. Installation and initial verification: Testing per DIN VDE 0100-600 by the electrical contractor.
6. Meter installation and commissioning: swa Netze installs the bidirectional meter. MaStR registration is mandatory.

What are the requirements for the meter location?

Requirement	Specification
Meter type	eHZ in three-point mounting system
Surge protection	Type 1+2 combined arrester (mandatory for new systems)
SLS switch	Selective line protection switch upstream of the meter
Space reserve	Min. 1 slot for smart meter gateway
Equipotential bonding	Connection to main earthing busbar

How are balcony power plants registered with swa Netze?

Since 2024, balcony power plants up to 800 W inverter power can be registered through a simplified process at swa Netze. Registration is done via the digital feed-in portal. Contact for installers: Tel. 0821 6500-8977 (Mon-Fri 08:30-10:00).

Grid Connection Process Overview

Important Documents and Forms

Which transmission system operator is responsible in Augsburg?

Augsburg is located in the TenneT control area. The responsible transmission system operator (TSO) is TenneT TSO GmbH. TenneT is responsible for system stability in the extra-high voltage grid (220/380 kV) and coordinates the feed-in of renewable energy at the transmission grid level. At the regional distribution grid level, Bayernwerk Netz is also an important player.

Level	Operator	Voltage Level	Relevance for PV/BESS
Transmission grid	TenneT	220-380 kV	System stability, EEG feed-in
Distribution grid	swa Netze	0.4-20 kV	TAB, grid connection, meter location
Customer system	System operator	0.4 kV (LV)	PV array, BESS, inverter

What are typical challenges for PV and BESS in Augsburg?

Augsburg has specific regional characteristics as a location for PV and BESS projects that must be considered during planning and assessment:

UNESCO World Heritage Water Management

Augsburg's historic water management system is a UNESCO World Heritage Site. PV systems in the old town and along the Lech canals require special coordination with the Lower Heritage Protection Authority.

Textile Quarter: Industrial Conversion

The Augsburg Textile Quarter (AKS, Glaspalast) is being converted into residential and commercial districts. The sawtooth roofs of former factories are ideal for PV — however, structural load-bearing capacity must be confirmed by an expert assessment.

LEW and swa Netze: Divided City Territory

In the Augsburg urban area, both swa Netze and Lechwerke (LEW Verteilnetz) are active. The jurisdiction boundary sometimes runs through the middle of residential areas — advance clarification is essential.

Bavarian Solar Mandate in Planning

Bavaria is discussing a solar mandate following the Baden-Wuerttemberg model. As Bavaria's third-largest city, Augsburg would be significantly affected — assessments regarding economic reasonableness are anticipated.

When is an expert assessment advisable?

Occasion	Our Service
Acceptance assessment	TAB conformity check, defect report
Dispute with grid operator	Independent technical evaluation
Systems from 30 kWp / medium voltage	Supervision, grid compatibility assessment
Defect assessment	DIN VDE 0100-600, thermography, EL
Capacity bottleneck	Grid analysis, alternative concepts
