Quick answer
Which zoning basis does a renewable energy project need in Poland?
A solar farm above 1 MW and every wind farm need a local zoning plan (MPZP, miejscowy plan zagospodarowania przestrzennego); since 1 September 2026 a decision on development conditions (WZ, decyzja o warunkach zabudowy) on a new application can be issued only where the municipality’s general plan (plan ogólny gminy) is in force. Solar farms also need an MPZP on class I–III agricultural or forest land and above 150 kW on class IV land; smaller ground-mounted PV can use a WZ decision where one is available, and rooftop PV needs no separate land-use designation.
Existing local plans remain valid. Where there is neither a suitable plan nor a WZ route, the investor can request a new plan or an integrated investment plan (ZPI, zintegrowany plan inwestycyjny), but the municipality is not bound by the request.

The 2026 planning reform: what changed for renewable energy projects
This page is a chapter of our legal guide to renewable energy investments in Poland. The zoning basis of a renewable project has always been either a local plan or a WZ decision. The 2023 planning reform changed the conditions for both: every municipality had to adopt a general plan, a new by-law that frames every later local plan and WZ decision. The deadline, moved several times, expired on 31 August 2026, and on that date the old municipal studies (studium uwarunkowań) lost force.
| Situation | What it means for a renewable project |
|---|---|
| The site is covered by a local plan (MPZP) | Nothing changes: local plans remain in force after 1 September 2026, whether or not the municipality has a general plan. |
| WZ application filed by 31 August 2026 | Decided under the previous rules, even where the municipality has no general plan. |
| WZ application filed from 1 September 2026 | A decision can be issued only where the municipality’s general plan is in force – and, if the site lies in more than one municipality, in each of them. |
| New local plan or amendment, no general plan | As a rule not possible after 1 September 2026; procedures that reached the consultation stage before that date may be completed under the previous rules. |
| WZ decision issued from 2026 | Expires five years after the date on which it became final. |
By 31 August 2026, 946 of Poland’s 2,479 municipalities – about 38% – had adopted a general plan, according to figures the Ministry of Development and Technology presented to the Sejm. In most municipalities, a renewable project without a local plan therefore has no WZ route for now.
In municipalities without a general plan, no new WZ decision can be issued – a significantly greater risk than the shortened validity of the decision itself, and one to build into the investment schedule.
Which zoning route does each renewable technology need?
The zoning instrument depends on the technology, the capacity and the land. The overview shows the general rule; the next sections explain the exceptions.
SOLAR
Ground-mounted PV farm
MPZP above 1 MW, on class I–III or forest land, or above 150 kW on class IV land
Otherwise an MPZP or, where available, a WZ decision. Micro-installations up to 50 kW as a rule need no WZ decision.
Rooftop or facade PV
No separate land-use designation
Installations on existing buildings generally need no zoning change, so the investor does not wait for a new or amended plan.
WIND
Onshore wind farm
MPZP only
Never a WZ decision. The plan sets the distance from homes: 10H, never less than 700 m. ZPI without simplifications.
Micro wind installation up to 50 kW
Confirm with the municipality
The 700 m and 10H distance rules do not apply.
Offshore wind farm
Maritime spatial plan and PSZW permit
Sited in the exclusive economic zone in areas designated in the maritime spatial plan, instead of land-based zoning.
BIOGAS
Agricultural biogas plant
MPZP or WZ decision
Above 0.5 MW, the environmental decision comes before the WZ decision.

Solar farms: when is a local zoning plan mandatory?
For photovoltaic farms the law links the capacity and the land class to the obligation to have a local plan. In three cases a WZ decision is not enough and the municipality must have an MPZP:
- a power plant on class I, II or III agricultural land or forest land,
- a power plant of more than 150 kW on class IV agricultural land,
- a photovoltaic power plant of more than 1,000 kW (1 MW), regardless of the land class.
Two simplifications work in the investor’s favour. Standalone PV plants of up to 1,000 kW on poor-quality soils – classes V, VI, VIz and wasteland – as well as rooftop installations can be sited without prior changes to the municipality’s general planning documents. Where there is no local plan, or the plan prohibits a PV farm, an integrated investment plan is a faster and simpler alternative to amending the plan, because for renewable installations other than wind the ZPI procedure is simplified.
In practice: on protected soil classes, the land may also have to be excluded from agricultural production before the building permit; this is a separate decision from the zoning basis.
Land classes and title are covered in site selection and land rights for renewable energy projects.
Wind farms: local zoning plan only
Wind power plants are subject to a special regime within the planning system. Unlike many other projects, they can be sited exclusively on the basis of a local zoning plan, which removes the flexibility of a WZ decision. The plan also sets the distance between turbines and homes: as a rule ten times the turbine’s total height (10H), and never less than 700 metres.
An integrated investment plan does not shorten the route for wind: none of the procedural simplifications that apply to other renewable projects are available. The procedure requires full coordination and consultation, including on distance requirements and public participation.
In practice: in a municipality without a general plan, a new local plan or an amendment is, as a rule, no longer possible after 1 September 2026, so a wind project without an existing plan depends on the municipality first adopting its general plan.
WZ decision for renewable energy projects
A decision on development conditions allows renewable projects to be sited where there is no local plan. For many renewable installations, the law provides significant exceptions to the standard requirements, in particular to the good-neighbourhood rule (zasada dobrego sąsiedztwa). The steps below show the order.
WZ DECISION FOR A RENEWABLE PROJECT · FIVE STEPS
1
Check that a WZ route exists
Not for wind farms, which need a local plan. An application filed by 31 August 2026 is decided under the previous rules; one filed from 1 September 2026 only where the municipality’s general plan is in force – in each municipality, if the site crosses a boundary.
2
Obtain the environmental decision first, where required
It comes before the WZ decision – for agricultural biogas plants above 0.5 MW, for example.
3
File the application
With a base map or cadastral map covering the impact area and an architectural and construction concept of the installation.
4
Receive the decision
It sets the conditions for fitting the installation into its surroundings; it is the zoning basis for the building permit.
5
Apply for the building permit within five years
A WZ decision issued from 2026 expires five years after the date on which it became final.
The general rules for WZ decisions and general plans, outside the renewable energy context, are explained in our guide to general plans and WZ decisions in Poland.
Integrated investment plan (ZPI) for renewable energy projects
The integrated investment plan is a special form of local plan, prepared at the investor’s request and adopted by the municipal council. It was introduced as an alternative to the traditional procedure for amending a local plan and allows the planning process to be run in close cooperation between the investor and the municipality.
- Scope: a ZPI can cover both the main project and the supporting infrastructure it needs, including roads and technical infrastructure.
- Simplifications: for certain renewable projects the law simplifies the procedure to speed up planning – for installations other than wind farms. The scope of these preferences is not uniform across technologies and has to be checked for the specific type of installation.
- Wind: no simplifications – full coordination and consultation, including distances and public participation.
The scope of statutory preferences for an integrated investment plan is not uniform across renewable technologies, so whether a simplification applies has to be verified for each type of installation.
Requesting a local plan or its amendment
If the site has no local plan, or the plan prevents the installation, the investor may ask the municipal authorities to adopt or amend one. The request is only a proposal: the municipality is not bound by it, and the law does not require it to consider the request. For solar and other non-wind technologies, the ZPI is often the more practical path because it is negotiated with the municipality.
In a municipality without a general plan, a request for a new or amended local plan meets an additional obstacle: after 1 September 2026, such a plan can as a rule be adopted only once the general plan is in force, apart from procedures that had reached the consultation stage before that date.
Zoning checks before you sign a land lease
The zoning basis decides whether a lease is worth signing. Before committing to a site, check for each plot:
- Local plan. An extract from the MPZP or confirmation that there is none, and whether the plan allows the specific installation.
- General plan. Whether the municipality’s general plan is in force – the status of general plans is published on geoportal.gov.pl – and, if the site crosses a municipal boundary, in each municipality.
- Land class. An extract from the land register (EGiB): it decides whether a PV farm needs an MPZP and whether the land must be excluded from agricultural production.
- Earlier applications. Whether a WZ application was filed by 31 August 2026, which is decided under the previous rules.
- Environmental decision. Whether the project needs one – see the environmental decision for renewable energy projects; where it does, it comes before the WZ decision.
Biogas plants have a separate guide: biogas and biomethane in Poland. The construction stage after the zoning basis is described in our guide to the property development process in Poland.

No, wind farms can be sited only on the basis of a local zoning plan, which also sets the distance from homes: 10H, and never less than 700 metres.
Can I still get a WZ decision for a renewable energy project after 1 September 2026?
On an application filed from 1 September 2026, only where the municipality’s general plan is in force; an application filed by 31 August 2026 is decided under the previous rules.
Do local zoning plans lose force if the municipality has no general plan?
No, existing local plans remain in force after 1 September 2026, and projects can be prepared and built on their basis.
How long is a WZ decision valid?
A WZ decision issued from 2026 expires five years after the date on which it became final.
Can a municipality adopt a new local plan without a general plan?
As a rule not after 1 September 2026; procedures that reached the consultation stage before that date may be completed under the previous rules.
What is an integrated investment plan (ZPI)?
A special local plan prepared at the investor’s request and adopted by the municipal council, which can cover the main project and its supporting roads and infrastructure, with simplified procedures for renewable installations other than wind farms.
Is the municipality obliged to adopt a local plan at the investor’s request?
No, the request is only a proposal; the municipality is not bound by it and the law does not require it to consider the request.
Does rooftop PV need a zoning change?
No, installations on existing buildings generally need no separate land-use designation in local zoning documents.
Which PV plants can be sited without changing the municipality’s general planning documents?
Standalone PV plants of up to 1 MW on class V, VI, VIz land and wasteland, as well as rooftop installations.
Does the environmental decision come before the WZ decision?
