Contract project development for co-location projects consisting of PV and BESS
Based on the greentech co-location analysis or comparable preliminary work, we develop your PV project with battery storage to ready-to-build status – prepared for implementation by an EPC.
From PV-only to an implementation-ready
co-location
greentech develops your PV project into a co-location with BESS. Our co-location contract project development starts where the target design for the battery storage has been determined – for example, based on our co-laocation analysis or comparable preliminary work. In doing so, we manage the entire process – from planning law, permits, and land securing to required expert reports, grid connection, and technical implementation preparation. In the end, you receive an individually tailored, ready-to-build co-location project that you can hand over to an EPC.
Where our contract project development starts in the
co-location process
Contract project development follows the co-location analysis and provides all necessary documents, evidence, and records for construction by an EPC
Co-location analysis
Contract project development
Develops the selected co-location variant to ready-to-build – with permits, grid connection, land securing, expert reports, and technical documentation.
EPC / Plant Construction
When does contract project development make sense?
Contract project development is aimed at PV projects that are to be further developed for co-location with a battery storage system. The prerequisite is that a specific PV starting situation already exists – for example, a fully developed PV system, one under construction, or one already in operation.
If you want to expand your PV project with BESS
You would like to develop a co-location project from a developed or existing PV project. We take over the further project development and manage the necessary steps until it is ready-to-build.
If the appropriate BESS variant is already fundamentally defined
A clearly defined target sizing is required for the project development of the co-location: Which storage solution should be integrated into the PV project and what role should it play in the project? This target sizing can come from a greentech co-location analysis, an external analysis, or an existing project decision. If no reliable target sizing is yet available, a co-location analysis may be useful beforehand. Once the preferred variant has been determined, we develop it further to ready-to-build in the next step.
If your internal project development lacks capacity or BESS know-how
Expanding a PV project to include BESS affects permits, grid connection, land, expert reports, technology, and stakeholder management. If internal resources or specific experience are lacking, we take over the structured further development as an external contract project development partner.
If you need a central partner for management
Co-location projects have many interfaces: authorities, grid operators, owners, experts, planners, and subsequent execution partners. greentech brings these topics together in a clear project structure – so that decisions can be made quickly, responsibilities are clearly clarified, and the next steps can be reliably executed.
If the project is to be developed to ready-to-build status
The goal is an implementation-ready co-location development. The result is a coordinated project consisting of PV and BESS that brings together technical, permitting, grid-related, and economic requirements and can be used as a basis for tendering, awarding, and execution by an EPC.
Components of contract project development for
co-location with BESS
greentech leads the selected co-location variant structured to ready-to-build. To this end, we coordinate the relevant work packages, manage the interfaces between those involved, and create a reliable project status for tendering, awarding, and EPC execution.
Project and stakeholder management
greentech takes over the central coordination of the development process and manages coordination with authorities, grid operators, owners, experts, planners, and other service providers. In this way, decisions, documents, and next steps come together in a clear project structure.
Planning law and permitting strategy
We lead the permitting path derived in the co-location analysis into execution. Depending on the project status, we coordinate, for example, preliminary building inquiries, building applications, adjustments to existing planning documents, or steps within the framework of urban land-use planning.
Land securing, leasing, and project-related contracts
We coordinate the necessary adjustments and clarifications regarding land, leasing, and project-related contracts, insofar as they are necessary for the integration of the battery storage system. This includes coordination with owners, contractual partners, and other parties involved (no legal advice).
Expert reports, mapping, and evidence
If additional expert reports, mapping, or evidence are required for the BESS expansion, greentech manages their commissioning, coordination, and integration into the project documents. Depending on the location, this may concern noise, fire protection, soil, water, environment, or visibility.
Grid connection and cable route securing
We implement the grid-side steps identified from the co-location analysis for the integration of the BESS. Depending on the project, this includes the extended grid application, coordination with the grid operator, technical grid connection design, cable route design, and the preparation of the required documents.
Technical execution preparation
greentech transfers the target system into an execution-ready technical project basis. This includes, for example, site layout and system design, technical interfaces between PV, BESS, and grid connection, as well as design review or the preparation of documents for tendering and EPC handover where applicable.
Marketing and operational perspective
The subsequent operational and marketing logic must match the technical and grid-side design. Therefore, we take the intended use of the BESS into account in the development process and coordinate relevant requirements early on with design, grid connection, and execution preparation.
White Paper
Integrating BESS – but how?
How do you turn a ground-mounted PV project — in development, under construction, or already in operation — into a permitted, technically feasible and economically viable co-location project with a battery energy storage system (BESS)? This whitepaper outlines the typical approach: from an initial co-loaction analysis, through a robust decision basis, to developing the selected target concept all the way to Ready-to-Build (RtB).
6 good reasons why greentech is the right partner for your project development
Experience from own BESS and co-location project development
greentech develops its own PV and BESS projects and understands the requirements of real-world implementation. This hands-on expertise feeds directly into project development for clients – from permitting and grid connection to technical DC and AC detailed design.
360° system perspective on the co-location project
Co-location arises at the interface of project development, technology, grid, and subsequent execution. greentech considers these topics in an integrated manner – from permitting and land securing to PV/BESS engineering, grid connection and integration, as well as SCADA solutions, through to ready-to-build status and EPC handover.
A central partner for many interfaces
Clear structure, individually tailored to your project
Co-location projects need a reliable development logic – but no off-the-shelf solution. greentech combines a clearly managed process with the individual results from co-location analysis or comparable preliminary work. In this way, the selected BESS variant is developed to ready-to-build status in line with the location, grid situation, permitting path, and project goal.
Planning security until ready-to-build status
The goal is a project status that is not only conceptually convincing but can also be transferred into execution. greentech further develops the selected co-location variant so that tendering, awarding, and EPC implementation can be based on a reliable foundation.
Fast entry based on preliminary work already completed
If the project status, target sizing, and open points are already available, project development can start directly on a reliable basis. greentech uses the existing preliminary work, for example from the co-location analysis, specifies the next steps, and transfers the identified work packages into a clear roadmap to ready-to-build.

FAQ: Contract project developmentÂ
Frequently asked questions about co-location contract project development and integration of BESS into existing PV systems
What does contract project development mean?
Contract project development means that greentech takes over the further development of an existing PV project into a co-location with BESS. The goal is an implementation-ready project status that can be used as a basis for tendering, awarding, and EPC implementation.
For which projects is contract project development suitable?
The service is suitable for PV projects that are to be expanded to include a battery storage system. The prerequisite is a specific PV starting situation – for example, a fully developed PV system, one under construction, or one already in operation.
Does the target sizing for the battery storage already have to be determined?
A reliable target BESS sizing should be available for project development. This can come from a co-location analysis by greentech or from comparable preliminary work. If no target design is yet available, the potential analysis is the sensible first step.
What is the difference to the co-location analysis?
The co-location analysis evaluates which BESS variant makes sense technically, grid-wise, permitting-wise, and economically. Contract project development starts after that: The selected variant is further developed until ready-to-build.
Which services does greentech provide in contract project development?
greentech coordinates the relevant work packages until ready-to-build. Depending on the project, these include project management, permitting, land securing, expert reports, grid connection (design), route, technical documentation, and preparation for EPC handover.
Does greentech also handle coordination with authorities and grid operators?
What does ready-to-build mean for a co-location project?
Is the EPC or plant construction part of the service?
No. Contract project development ends with implementation-ready development and preparation for EPC handover. The subsequent construction of the plant takes place via EPC or plant construction as a separate service.
Can the project be handed over to an external EPC after development?
Yes. The explicit goal of the service is to create a reliable project basis for tendering, awarding, and EPC execution. The execution can then be carried out by greentech or another EPC partner.
Does greentech also have to have carried out the previous co-location analysis?
Not necessarily. If a reliable target sizing and the relevant project bases are already available, greentech can build on them. If the co-location analysis was created by greentech, a particularly fast entry is possible because the project status, target variant, and open points are already known.
