Energy investment in Poland – what formalities should a company check before implementation?

In Poland, legal and regulatory support for an energy investment is not about ticking off one universal list of documents. The scope of permits, licences, notifications, approvals and decisions depends on the technology, project parameters, location, grid-connection method and the type of work planned.

For a company, the right approach is to prepare a project formalities map: a set of obligations and actions assigned to a specific project variant and arranged in the correct sequence. Such a map should show not only “what may be required”, but above all what triggers each obligation, who is responsible for each step, what document is produced and what the next stage depends on.

The most common mistake is not omitting a single item from a checklist. The real problem is starting design work, procurement or construction before determining which formalities are critical for the selected investment variant and in what order they must be completed.

Why is there no single list of formalities for all energy investments?

The term “energy investment” covers projects that differ significantly in technical and legal terms. In a company, this may include photovoltaic systems, energy storage, heat sources, CHP, upgrades to electrical networks, boiler-house reconstruction, heat-recovery systems, compressed-air systems, new refrigeration equipment or production-process upgrades.

Even two projects using the same technology do not necessarily follow the same route. Relevant factors may include:

• rated capacity and other equipment parameters;
• whether a new facility is being built or equipment is being installed in an existing building;
• the scope of alterations to the structure, installations and technical infrastructure;
• the location of the property and applicable spatial-planning provisions;
• proximity to protected areas, waters or other areas subject to special regulations;
• the grid-connection method and any change to existing supply conditions;
• the type of pressure equipment, tanks, pipelines or other technical equipment;
• emissions, noise, waste, water abstraction, wastewater discharge or other impacts;
• the investment financing model and the conditions of support instruments.

In practice, the right starting question is therefore not “what documents are required for an energy investment?”, but “which characteristics of this specific project trigger particular obligations?”

Project brief – information needed before analysing formalities

Before preparing the formalities map, it is worth creating a short project brief. It does not have to be a complete design package, but it should contain enough information for an initial legal and technical classification.

1. Technology and function of the installation

Describe not only the name of the technology, but also its role at the site. Will the installation cover only the company’s own demand? Will it generate electricity, heat or cooling? Can energy be exported to the grid? Will the investment change the way an existing process is supplied?

2. Key technical parameters

The required data depend on the technology. They may include electrical or thermal capacity, storage capacity, pressure, tank volume, boiler and pipeline parameters, fuel type, flow rates or the area of land occupied.

There is little value in creating one universal parameter table for every project. Instead, identify the parameters on which the applicable procedures depend under the relevant regulations.

3. Scope of works and installation location

Determine whether the investment involves:

• installing equipment in an existing facility;
• altering existing installations;
• interfering with the building structure;
• constructing foundations, containers, stations, lines or other structures;
• an installation on a roof, façade, on land or within an existing process area of the site.

This information is needed to classify the project correctly under the Polish Building Law. The fact that a project is “energy-related” does not by itself determine whether a building permit, notification or exemption from both procedures applies.

4. Location

The formalities map should include from the outset:

• plot number and cadastral district;
• legal title to the property;
• information on the local spatial development plan;
• basic environmental constraints;
• information on Natura 2000 sites and other forms of nature protection;
• the relationship of the project to watercourses, water facilities and flood-risk areas;
• any heritage-conservation or infrastructure restrictions.

In 2026, checking the current planning documents in the specific municipality has become particularly important. Poland’s spatial-planning reform is being implemented in stages, and the Act of 30 April 2026 introduced further transitional provisions and deadlines. Planning status should therefore not be determined on the basis of an old audit or information from several months earlier; the current status must be checked for the location and the time at which the project is being developed.

5. Use of networks and utilities

At the concept stage, determine whether the project:

• uses the existing connection without changing its parameters;
• requires an increase in connection capacity;
• creates a new generating source or energy storage facility;
• provides for export of energy to the grid;
• requires a new connection point or reconstruction of infrastructure;
• affects other utilities, such as gas, water or district heating.

Not every site upgrade requires new connection conditions. However, if the project changes how the installation interacts with the network, connection formalities may become one of the key elements of the project schedule and cost.

6. Environmental impacts and utilities management

Determine whether the investment may change, among other things, air emissions, noise levels, water and wastewater management, waste volumes, the storage of substances or impacts on the surroundings. This is only the starting point for assessing whether environmental or sector-specific procedures are triggered.

7. Equipment subject to specific requirements

When upgrading heat sources, steam systems, compressed-air systems, pipelines, tanks or district-heating substations, separately verify whether the specific equipment and its parameters bring it within the scope of technical inspection by the Polish Office of Technical Inspection (UDT).

8. Financing and the point at which the project starts

The source of financing may impose its own sequence of actions. This applies, for example, to instruments where an application must be submitted before a specified investment commitment is made. For projects planned under Poland’s energy-efficiency certificate system, the sequence is particularly important: the Polish Energy Efficiency Act links the “start of works”, among other things, to the first legally binding commitment to order equipment or another irreversible commitment, while the application is submitted by an entity planning to start the works.

Energy investment formalities map – 7 steps

A good formalities map is not a list of statutes. It is a decision-and-dependency diagram for a specific investment variant.

Step 1. Identify the technology, variant and location

First, define the scope of the variant being analysed. If a company is comparing, for example, rooftop PV, a ground-mounted installation and a generating source combined with energy storage, it is worth treating them as three separate regulatory variants. Otherwise, requirements that apply to only one of them can easily be combined incorrectly.

Step 2. Verify spatial planning and legal title

The verification should cover the current local spatial development plan (MPZP) or other applicable planning basis, and whether the investor has the legal title required to carry out the planned process. For projects on third-party land, relevant documents may include lease, rental or easement agreements, or other instruments securing the required rights to the site.

A legal obligation arises where the regulations require a specific decision, consent or proof of rights to the property for the planned project. A good practice, on the other hand, is to verify the legal title and property restrictions before expensive design work begins, even if the document is formally required only at a later stage.

Step 3. Determine the building-law route

Next, classify the actual scope of works under the current Polish Building Law. Exemptions provided for one technology should not be extended to other installations.

Photovoltaics are a good example. Poland’s General Office of Building Control (GUNB) currently indicates that installing photovoltaic equipment with an installed electrical capacity of no more than 150 kW generally does not require a building permit or notification. At the same time, for equipment above 6,5 kW, the regulations require the design to be agreed in terms of fire protection and the competent State Fire Service authorities to be notified after installation is completed and the system is put into use.

This clearly shows why “no building permit required” does not mean “no formalities”.

Step 4. Check environmental procedures

A decision on environmental conditions is not automatically required for every energy investment. Under the Polish EIA Act, the obligation is linked to projects that may always or potentially have a significant effect on the environment, with the categories further specified in a regulation of the Council of Ministers.

The classification should therefore cover the exact scope, parameters and location of the project, rather than the technology name alone. In addition, a project that does not fall within a category requiring an environmental decision may still require a separate assessment due to a potentially significant effect on a Natura 2000 site.

If a decision on environmental conditions is required, it affects the sequence of the process. Article 72 of the Polish EIA Act requires it to be obtained before a number of subsequent decisions, including certain building and location decisions specified in the Act and, in specific cases, before submitting a building notification.

Step 5. Verify grid connection and network conditions

The Polish Energy Law sets out the rules for connection to networks. For the investor, however, the key technical question should be asked earlier: does the project actually require a new or modified connection?

If it does, the technical and economic conditions for connection, the network operator’s requirements and the effect of any network reinforcement on the schedule and CAPEX should be checked sufficiently early. The Polish Energy Regulatory Office (URE) notes that where an energy company refuses to conclude a connection agreement, it has specific information obligations and, at the applicant’s request, must provide information on the network-development measures required and the costs specified in the regulations.

In practice, this branch of the map should not be left until the end of the design process. A different connection variant may change the selected capacity of the generating source, storage system, transformer, protection equipment or controls, and therefore the economics of the entire investment.

Step 6. Add sector-specific requirements: UDT, PSP, Polish Waters, URE and others

This is where over-simplification is most likely. There is no general rule that “an energy installation is subject to UDT” or that “every renewable-energy project must be agreed with the State Fire Service”.

UDT. Technical inspection applies to specific types of equipment and installations defined in Polish regulations. The official UDT list includes, among other things, selected equipment in district-heating substations and boiler houses, boilers, tanks in compressor units and specified pipelines. Qualification must be carried out for the actual equipment and its parameters.

PSP. Fire-protection obligations depend on the type and parameters of the investment. The example of PV installations above 6,5 kW shows that such obligations may arise even where the installation itself is exempt from a building permit and notification.

Polish Waters. If a project involves water facilities, water services, special use of waters or other activities specified in the Polish Water Law, a water-law permit or water-law notification may be required. This is not a requirement for every energy investment.

URE. For selected generation projects, connection projects or projects using specific support mechanisms, procedures before the President of the Polish Energy Regulatory Office may be relevant. The scope must be determined separately for the business model and installation parameters.

Step 7. Map the dependencies and identify the critical path

Only after the individual branches have been identified can a regulatory schedule be built. For each item, it is worth recording:

1. what triggers the obligation;
2. what document or action is the result;
3. who is responsible for preparation;
4. which authority or entity receives the matter;
5. what data and designs are required;
6. what must happen beforehand;
7. which subsequent stage is blocked until the action is completed.

This turns the formalities map into a project-management tool rather than merely a list of documents.

Legal and regulatory project support also covers agreements and administrative proceedings

The formalities map should not end with permits and decisions. If a project is implemented on third-party land or requires use of third-party infrastructure, the required lease, rental, easement and connection agreements, or other documents defining the parties’ rights and obligations, must be determined separately. Not every investment requires every one of these documents; the scope depends on the delivery model, property ownership and connection method.

A separate branch concerns the course of proceedings before public authorities. In practice, this may include preparing applications, responding to requests, supplementing documentation, submitting explanations and, where necessary, representation by a duly authorised person. An administrative decision should not be described as the subject of “negotiations” with an authority. The authority decides the case on the basis of the law and the evidence in the proceedings.

Negotiations may, however, concern contractual relationships, for example with the landowner, network operator, contractor or technology supplier. Separating administrative proceedings from contracts is also important for the schedule: signing an agreement at the wrong time may be irrelevant to one route but, under another route – for example a specific support mechanism – may affect eligibility for that mechanism.

Legal obligation versus good practice – do not confuse them

Investment documentation should clearly identify which activities are required by law and which are risk-management measures.

This distinction also matters organisationally. Good practice is not “another authority requirement”; it is an action intended to reduce the risk of redesign, delay or loss of project viability.

How can formalities change the schedule or economics of an investment?

Example 1. Photovoltaics: no permit does not mean no procedures

A company plans a PV installation on an existing facility. If the installation of the equipment falls within the exemption under the Polish Building Law for installed capacity not exceeding 150 kW, the absence of a permit and notification can shorten the building-law route.

This does not end the analysis. Above 6,5 kW, fire-protection requirements must be taken into account. Connection, planning and environmental issues relevant to the specific location and variant must be checked separately.

Impact on the decision: the investor should not estimate the project schedule solely on the basis of the statement “PV does not require a permit”.

Example 2. Connection conditions change the technical variant

A site plans a new generating source or storage system and assumes a certain capacity based on the consumption profile. If the project requires a change in its relationship with the network, available connection options may require additional infrastructure or a change of variant.

Impact on the decision: CAPEX calculated without a realistic connection variant may be incomplete. Instead of refining equipment design in isolation from the network, it is better to carry out the energy analysis, electrical concept and connection route in parallel.

Example 3. Polish white certificates and ordering equipment too early

A company plans an energy-efficiency upgrade and includes income from energy-efficiency certificates in its business case. In this situation, the sequence of actions has a direct financial impact.

The Polish Energy Efficiency Act defines the “start of works”, among other things, as the start of construction works, the first legally binding commitment to order equipment or another commitment that makes the investment irreversible – whichever occurs first. At the same time, an application for an energy-efficiency certificate is submitted by an entity planning to start the works, and the Act provides for a negative consequence where the works started before the application was submitted.

Impact on the decision: signing an order at the wrong time may deprive the project of an assumed source of financing. In this case, the formalities map must be linked to the procurement schedule.

Example 4. Boiler-house upgrade: UDT only after equipment classification

Replacing a heat source may involve boilers, tanks, pipelines and other components with different parameters. It cannot be assumed that the entire investment “is subject to UDT” or “is not subject to UDT” based solely on the project name.

Impact on the decision: equipment parameters must be classified before ordering. If an item is subject to technical inspection and requires specific documentation or a decision before operation, omitting this branch from the schedule may delay commissioning.

Example 5. Water-using installation: permit or notification on the critical path

A heat-recovery, cooling or new-process project may involve a change in water abstraction, wastewater discharge or the construction of a water facility. Only an analysis of the scope can determine whether a water-law permit, notification or neither procedure applies.

Impact on the decision: if a water-law procedure is required and is a prerequisite for a later building-law stage, failing to account for it at the outset may delay the entire project.

How should the sequence of formalities be determined?

Not every procedure has to be carried out sequentially. Some analyses and approvals can start in parallel. The key is to identify dependencies that cannot be bypassed.

An example sequence is as follows:

1. Technical concept + location brief – without these, there is no basis for classification.
2. Initial planning, environmental, building-law, network and sector-specific classification – this helps identify potential blockers.
3. Decision on the selected variant – only after formalities have been reflected in CAPEX and the schedule.
4. Procedures that condition subsequent decisions – for example a decision on environmental conditions, if required and if it must precede specified decisions.
5. Conditions and approvals affecting the detailed design – for example connection requirements, fire protection and technical-equipment requirements.
6. Building-law route and implementation – in accordance with the classification of the actual scope of works.
7. Actions required before commissioning or operation – where the regulations require them for the relevant equipment or installations.
8. Support and financing – application deadlines should be integrated into the schedule before actions that could breach the conditions of the programme or scheme.

It is useful to maintain one dependency table with the following labels: mandatory / conditional / good practice / not applicable.

What should the formalities map deliver?

A well-prepared pre-implementation analysis should end with a document that can be used during design, procurement and implementation. The minimum scope should include:

• description of the selected technical variant and location;
• list of identified requirements together with the basis that triggers them;
• list of formalities considered not applicable to the project, with a brief justification;
• authorities, operators and other participants in the process;
• required input data and documents;
• sequence and dependencies between procedures;
• responsibilities of the investor, designer, contractor and advisers;
• items affecting CAPEX, OPEX or the schedule;
• risks requiring a management decision;
• “go/no-go” points after which it is safe to proceed to the next stage.

A particularly useful column is “why does this formality apply to the project?”. It prevents the team from automatically copying requirements from an older investment.

“Go/no-go” checklist before placing the main contractor order

Before signing the main purchase order or construction contract, it is worth checking:

• ☐ whether the technical variant and location have been finalised;
• ☐ whether the current planning status has been checked;
• ☐ whether the Polish Building Law route has been determined;
• ☐ whether environmental classification has been completed;
• ☐ whether it is known if the project requires a new or modified connection;
• ☐ whether equipment potentially subject to UDT has been identified;
• ☐ whether PSP, water-law and other sector-specific requirements have been checked;
• ☐ whether it has been determined which decisions must precede subsequent stages;
• ☐ whether operator and authority requirements have been reflected in the design and budget;
• ☐ whether the conditions of grants, Polish white certificates or other instruments restrict the timing of placing an order;
• ☐ whether each formality has an owner and a control deadline;
• ☐ whether contingency has been allowed for document supplements and a change of variant.

This list is a good investment-management practice, not a universal catalogue of legal obligations.

Formalities should be checked before the final investment decision

A formal review carried out only after a supplier has been selected often answers the question: “how can the chosen variant be made compliant?”. A much more valuable earlier analysis asks: “which variant can actually be implemented, by when and with what level of risk?”.

This is why formalities should be part of investment preparation alongside technical and economic analysis. For a major upgrade, the formalities map should be combined with an energy audit, technical concept and options analysis. For photovoltaic, storage, CHP or heat projects, the formal assessment should be based on data specific to the selected solution rather than on a checklist copied from another technology.

If an upgrade is expected to generate energy savings and the investor is considering Polish white certificates, eligibility for the scheme should be verified before making binding investment commitments, because the timing of the start of works matters for this route.

Frequently asked questions

Is there one list of documents for every energy investment?

No. The list depends on the technology, parameters, scope of works, location, connection method, type of equipment and impacts. The correct approach is to build a formalities map for the specific variant.

Does exemption from a building permit mean there are no formalities?

No. An exemption under the Polish Building Law does not automatically exclude requirements arising from other regulations. For example, certain PV installations may still be subject to fire-protection obligations, while connection or environmental issues may apply independently.

Does every energy investment require a decision on environmental conditions?

No. The obligation depends on project classification under the Polish EIA Act and the current implementing regulation, as well as the location and possible impacts, including on Natura 2000 sites.

Does every item of energy equipment have to be reported to UDT?

No. Technical inspection applies to specified types of equipment that meet the relevant criteria. The specific item of equipment and its parameters must be classified, not merely the investment by name.

When should grid-connection feasibility be checked?

If an investment may require a new connection, increased capacity, a new generating source or storage facility, or another change in its relationship with the network, the analysis should start at the concept stage. The result may affect the selected variant, budget and schedule.

How can Energy Trend support investment preparation?

Preparing an energy investment requires technical, economic and regulatory issues to be considered together. We can help organise input data, identify areas requiring separate classification, prepare a dependency map and combine it with an energy-efficiency analysis and technical options assessment.

Where a matter requires specific professional authorisations or representation before public authorities, the scope of work should be appropriately divided between the investor, designers, competent experts, lawyers and other specialists.

If you are preparing an investment and want to verify its route before selecting a contractor, contact Energy Trend.
