Maturity Assessment Process for Network Operators

Preparation & Support

Grid connection points for renewable energy are limited. Grid operators are increasingly allocating available capacity through structured maturity assessment processes: Only projects with a sufficiently high score are granted a grid connection. netzkontor nord prepares project developers nationwide for these scoring procedures—for ground-mounted PV systems, wind energy, and battery storage.

What is a maturity assessment process?

When grid operators receive more connection requests than available capacity, they need a prioritization system. The maturity assessment process is that system. The grid operator evaluates each project according to a defined set of criteria and allocates grid connections based on this assessment.

The evaluation considers approval readiness, secured land, the status of the grid connection, and the plausibility of the implementation schedule. Projects that do not fully and consistently demonstrate these criteria lose points in the scoring process. Often, this is not due to the quality or progress of the project, but rather to gaps in the documentation or inconsistencies between the schedule and the status of approvals.

Typical Evaluation Criteria in the Maturity Assessment Process

Readiness for Approval:

Has the BImSchG procedure been completed, has the zoning plan been adopted, and has compliance with building codes been demonstrated? Projects with full approval receive significantly more points than projects in early planning phases.

Land Securing:

Lease agreements, proof of ownership, and the absence of restricted areas are relevant to the scoring in the maturity assessment process. A secured site counts; a non-binding option does not.

Grid connection readiness:

Has the grid connection request already been submitted or approved? Is a capacity assessment available? For solar and wind projects, grid connection readiness is often the limiting factor in the scoring process.

Implementation Schedule and Project Progress:

Grid operators assess whether the planned construction period aligns with the project’s actual maturity. Projects with verifiable progress and a robust timeline are rated significantly higher in the maturity assessment than greenfield projects without prior work.

What netzkontor nord Does for You

We assist project developers in preparing for and conducting maturity assessment processes.

We do not act as a representative vis-à-vis the grid operator. Our work begins earlier: We ensure that your project is fully prepared, consistent, and optimized for scoring before it is submitted.

Analysis of the grid operator’s requirements: 

We evaluate the respective grid operator’s scoring system, identify the criteria with the greatest impact on the score, and derive a concrete action plan from this analysis.

Assessment of approval and implementation readiness:

We review your project’s approval status based on PV, wind, or storage criteria: compliance with building codes, status under the Federal Immission Control Act (BImSchG), nature conservation considerations, and current grid connection status.

Structuring of supporting documentation:

Each piece of supporting documentation is assigned to an evaluation criterion within the maturity assessment process. The result is verifiable documentation that the grid operator can efficiently evaluate.

Gap Analysis and Mock Scoring:

We identify missing documentation, simulate the grid operator’s evaluation, and prepare your team for follow-up questions during the process.

Submission and Process Support: 

We finalize the documentation, assist with the submission, and provide support in the event of additional requests from the grid operator during the ongoing maturity assessment process.

Who is the support service for the maturity assessment process intended for?

This service is designed for project developers competing for scarce grid capacity—whether they’re working on a single project or a portfolio, whether they’re nearing the submission deadline or just beginning project preparation.

PV project developers:

Ground-mounted solar plants where grid connection capacities are allocated through a scoring process.

Wind farm developers:

Onshore projects in regions with limited grid capacity and high competition for feed-in points.

Storage developers:

Battery storage and hybrid systems, where system services and CLS capability constitute separate evaluation categories in the maturity assessment process.

IPPs, energy platforms, and investors:

Companies with multiple projects that require a uniform approach to the maturity assessment process across their entire portfolio.
