Purpose

The skill examines whether a connection request – in particular for EEG installations – is enforceable, identifies the relevant connection regime (general claim under §§ 17, 18 EnWG vs. priority EEG connection under §§ 8 et seqq. EEG), and prepares the argument vis-à-vis the grid operator as well as any BNetzA decision procedure (§§ 31 et seqq. EnWG). It addresses the typical points of dispute: grid connection point, capacity shortage, cost bearing, implementation deadlines.

Inputs

• Installation type and capacity (PV, wind, biomass, storage; kW/MW)
• Grid level (low voltage, medium voltage, high voltage, extra-high voltage)
• Grid operator (DSO / TSO) and previous correspondence (application, connection commitment, refusal)
• alleged reason for a delay or refusal (in particular capacity shortage, technical requirements)
• BImSchG approval status (for wind and large installations)
• Client's position: installation operator, final consumer, supplier

Sub-agent architecture

Researcher supplies §§ 17, 18 EnWG, §§ 8, 10, 12 EEG, NAV/NDAV provisions, BNetzA determinations as well as BGH KZR and OLG Düsseldorf case law. Drafter prepares the claim review in the style of a legal opinion, formulates the connection/information request to the grid operator and prepares the BNetzA application under § 31 EnWG. Reviewer checks whether the connection regime is correctly delineated, whether the BImSchG approval is addressed and whether complaint/hearing obligations (§ 67 EnWG, § 75 EnWG) are taken into account.

Procedure

1. Delineation of the connection regime

Before any review, clarify which regime is relevant:

Facts	Regime	Norm
Final consumer low voltage	General connection obligation	§ 18 EnWG in conjunction with NAV
Final consumer medium/high voltage	Non-discriminatory grid access	§ 17 EnWG; §§ 20 et seqq. EnWG
Installation for generating renewable energy / CHP	Priority connection under EEG/KWKG	§§ 8, 10 EEG; § 3 KWKG

For EEG installations, the EEG regime takes priority: shortest grid connection point, priority connection, offtake and transmission obligation (§§ 8, 10 EEG), grid expansion obligation under § 12 EEG.

2. Claim requirements under §§ 17, 18 EnWG

§ 18 EnWG establishes the general connection obligations vis-à-vis the basic supplier in the low-voltage grid. § 17 EnWG establishes a non-discriminatory connection and grid access claim otherwise. Requirements:

• Connectability of the grid (technically and economically reasonable)
• Non-discrimination (no extraneous unequal treatment)
• Fee framework under StromNEV/GasNEV / NAV / NDAV

Exceptions/grounds for refusal are conclusively regulated in Section 17(2) EnWG; the burden of presentation and proof lies with the grid operator.

3. Priority connection pursuant to Sections 8 et seq. EEG

The grid operator is obligated to connect a EEG installation without delay and with priority at the technically suitable grid connection point with the shortest distance (Section 8(1) EEG). The costs of connection shall be borne by the installation operator up to the connection point; the costs of grid expansion shall be borne by the grid operator (Section 16 EEG, Section 12 EEG).

Central procedural obligations of the grid operator (Section 8(5), (6) EEG):

• Time schedule for the connection within 8 weeks of application
• Concrete connection offer with grid connection point and cost estimate
• In the event of a dispute over the connection point: obligation to prepare a comparative calculation at the request of the operator

4. Conflict case of capacity shortage

If the grid operator pleads capacity shortage, a distinction must be made:

• Section 12 EEG (grid expansion obligation) – the grid operator must optimise, reinforce and expandits grid, insofar as this is economically reasonable. A refusal of connection due to lack of capacity presupposes that even the expansion would be economically unreasonable.
• Section 11 EnWG (safety and reliability) – concerns operation, not connection; does not justify a general refusal of connection.
• Feed-in management pursuant to Section 13 EnWG / Section 14 EEG is the milder measure compared with refusal of connection.

The prevailing view (cf. Frenz/Müggenborg, EEG, Section 12 marginal no. 1 et seq. [unverifiziert]) understands Section 12 EEG as a specialised statutory concretisation of Section 11 EnWG for EEG installations.

5. Connection commitment and implementation plan

• Connection commitment as a binding offer by the grid operator; acceptance by the installation operator establishes a connection contract.
• Implementation deadlines pursuant to Section 27a EEG (penalties for failure to commission after award).
• The need for BImSchG approval for wind/large installations is a preliminary question; without a final (or at least immediately enforceable) approval, as a rule there is no enforceable connection claim.

6. BNetzA administrative decision procedure Sections 31 et seq. EnWG

In the event of a dispute over connection, grid access, grid fees or refusal, the administrative decision procedure of the BNetzA is available (Section 31 EnWG). The application contains:

• Presentation of facts with evidence (correspondence, connection application, reasons for refusal)
• specific application (e.g. order of connection, determination of the grid connection point)
• Statement of grounds with legal basis
• Right of all parties to be heard (Section 67 EnWG)

Against the decision, appeal to the OLG Düsseldorf admissible within one month (§ 75 EnWG).

Alternatively, in consumer matters: Schlichtungsstelle Energie (§ 111b EnWG) as an out-of-court arbitration procedure.

VII. Quellenverzeichnis

Example (legal opinion style, abridged)

Facts. The client plans a ground-mounted PV system with 12 MWp in the medium-voltage grid. The DSO refused the connection citing a lack of capacity and referred to a waiting period of 36 months.

Legal basis. The connection claim follows from § 8(1) EEG: the grid operator is obliged to connect an EEG system promptly and with priority at the technically suitable connection point. § 17 EnWG is not applicable in addition, since § 8 EEG is lex specialis (cf. Müggenborg, in: Frenz/Müggenborg, EEG, 6th ed. 2023, § 8 marginal no. 1 et seq. [unverifiziert]).

Lack of capacity. The objection of lacking capacity does not, in itself, justify refusal of connection. § 12 EEG establishes an obligation of the grid operator to expand the grid insofar as such expansion is economically reasonable. § 11 EnWG (safety, reliability) concerns grid operation, not connection. The burden of presentation and proof for economic unreasonableness lies with the grid operator.

Conclusion. Connection claim in principle 🟢. Recommendation: written request for submission of a capacity and expansion calculation within four weeks; in case of refusal, application for a decision procedure pursuant to § 31 EnWG with BK6 of the BNetzA. Complaint to the OLG Düsseldorf pursuant to § 75 EnWG remains reserved (deadline: 1 month from service of the decision). 🟡 regarding the realization date, since grid expansion experience shows a procedure duration of 12–24 months.

Risks / typical mistakes

• Wrong connection regime chosen (§ 17 EnWG instead of § 8 EEG) – the basis for the claim falls too short, the priority claim is lost.
• Grid connection point adopted without scrutiny – without a comparative calculation pursuant to § 8 (5), (6) EEG, unnecessary connection costs are threatened.
• Capacity shortage accepted without review – the grid expansion obligation under § 12 EEG remains disregarded.
• BImSchG permit not clarified – without a (immediately enforceable) permit, no enforceable connection for wind/large-scale installations.
• Complaint deadline under § 75 (4) EnWG (1 month) missed – the BNetzA decision becomes final.
• Mixing with energy antitrust law (§§ 19, 29 GWB in conjunction with § 30 EnWG) – belongs in the plugin kartellrecht, here only an interface note.
