The construction of a biogas plant may require, in particular, verification of the local spatial development plan or obtaining a zoning decision, completion of environmental procedures, obtaining a building permit, securing connection conditions to the relevant utility networks, and meeting regulatory requirements related to the production of energy, biogas, or biomethane. The exact scope of formalities depends on the location, type of installation, substrates used, technical parameters of the project, and the intended business model.

A biogas plant is a specific type of energy infrastructure project. It combines elements typical of renewable energy sources, construction processes, waste management, environmental protection, and technical infrastructure. Therefore, project preparation should not begin solely with the question of obtaining a building permit. First, it is necessary to determine whether the selected location, technology, substrates, and offtake model for the produced output allow the project to be implemented successfully.

In this article, we explain:

  • what planning and zoning issues should be verified before commencing the project;

  • when environmental, waste management, and water and wastewater obligations should be assessed;

  • the importance of the building permit and legal title to the property;

  • why grid connection conditions should be examined at an early stage;

  • how the chosen production model affects regulatory obligations.

In What Order Should a Biogas Plant Project Be Prepared?

The process usually begins with an analysis of the project location, planning documents, technology, type of substrates, and the actual possibilities of connecting the installation to the relevant networks. The next step is to determine the scope of environmental procedures and any permits related to water and wastewater management or waste management.

Subsequent stages may include preparation of the construction design, obtaining a building permit, entering into the required grid connection agreements, and fulfilling regulatory requirements applicable to the production and sale of energy, biogas, or biomethane. Some of these activities may be carried out in parallel; however, their sequence should always reflect the characteristics of the specific project.

1. Does the Local Planning Framework Allow the Construction of a Biogas Plant?

The first step is to verify the planning documentation applicable to the selected site. If a local spatial development plan is in force, it should be checked whether it permits the location of a biogas plant or other development that would allow such an installation to be implemented. If there is no local plan, it may be necessary to obtain a zoning decision.

Certain agricultural biogas plants may benefit from specific facilitations. However, these apply only to projects that meet particular requirements relating to the investor, location, technical parameters, and substrates used. Therefore, not every biogas plant qualifies for a simplified procedure. Depending on the project, an Integrated Investment Plan may also be relevant.

2. Is an Environmental Decision Required for a Biogas Plant?

Environmental obligations must be assessed based on the parameters and location of the specific project. In the case of biogas plants, not only an environmental decision may be required, but also subsequent permits related to the use of the environment.

The assessment should take into account the project's impact on its surroundings, including odours, noise, transport of substrates, emissions, waste management, and the handling of digestate. Water and wastewater management also requires separate consideration, including water abstraction, wastewater discharge, management of stormwater from paved areas, and any leachate originating from substrate or digestate storage areas.

Where the installation is linked to a landfill site, landfill gas and landfill leachate must also be considered.

3. How Should the Site for a Biogas Plant Be Secured?

Before applying for a building permit, the investor must prepare the construction design documentation and demonstrate the legal right to use the property for construction purposes. For this reason, legal title to the land should be secured at an early stage, for example through a lease agreement or another agreement concluded with the property owner.

The agreement should reflect the planned investment timeline and take into account the time required to obtain permits, complete construction works, and operate the installation thereafter. This helps minimize the risk of losing access to the site before the investment process is completed.

4. What Permits Are Required for the Construction and Commissioning of a Biogas Plant?

A building permit may cover not only the main installation, but also associated road, technical, and process infrastructure. Therefore, the scope of the permit application should correspond to the entire construction project rather than only its principal elements.

Upon completion of construction works, additional formalities related to completion of the works or obtaining an occupancy permit may be required. Lawful operation of the installation can begin only after all requirements applicable to the specific project have been fulfilled.

5. When Should Grid Connection Conditions Be Applied For?

The possibility of connecting the installation to the relevant networks should be examined in parallel with the location analysis and preparation of project documentation. A biogas plant may require access to electricity, gas, district heating, water supply, or sewerage networks.

The inability to export energy, heat, gas, or biomethane may prevent the commercial operation of even a properly designed installation.

Where the business model assumes the sale of the produced output, the investor should verify offtake possibilities at an early stage and plan the appropriate contractual framework. Depending on the project, this may include, among others, a connection agreement, distribution agreement, or energy or gas sale agreement.

6. Does Operating a Biogas Plant Require a Licence or Registration?

The scope of regulatory obligations depends on what the installation is designed to produce and how it will operate. A biogas plant may produce electricity, heat, biogas, agricultural biogas, or biomethane. Each of these scenarios requires a separate legal assessment.

It should be determined whether a licence, entry in the relevant register, notification to a competent authority, or compliance with a support scheme is required. In the case of agricultural biogas, the register maintained by the National Centre for Agricultural Support (KOWR) may be relevant. For biogas, biomethane, or energy production, obligations involving the Energy Regulatory Office (URE) may arise.

Where the installation forms part of a broader business model, such as an energy cooperative, the analysis should also cover the operational and settlement rules applicable to that structure.

Frequently Asked Questions About Biogas Plant Development

Does every biogas plant require an environmental decision?

No. This cannot be determined solely on the basis of the type of project. The obligation depends, among other things, on the project's parameters, location, and its classification under environmental regulations.

Can a biogas plant be built where there is no local spatial development plan?

The absence of a local plan does not always prevent development. Depending on the nature of the project, it may be necessary to obtain a zoning decision or use another appropriate planning instrument.

Does a biogas plant require a building permit?

The construction of the installation together with its associated technical, road, and process infrastructure may require a building permit. The exact scope of formalities should be assessed on the basis of the specific project.

Does operating a biogas plant require a licence?

Regulatory obligations depend on whether the installation produces electricity, heat, biogas, agricultural biogas, or biomethane, as well as on the adopted business model.

What most commonly prevents the implementation of a biogas plant project?

The most significant risks usually concern the project location, grid connection possibilities, legal title to the property, and compliance with environmental, waste management, and energy regulations. These issues should therefore be assessed before substantial project costs are incurred.

Must all procedures be completed sequentially?

Not necessarily. Certain procedures and consultations may be carried out in parallel, particularly discussions with network operators, location analysis, and preparation of documentation. However, the project schedule should always take into account dependencies between individual permits, approvals, and decisions.
