The cadastral district and parcel number appear in a land registry extract and in the notarial deed, and the parcel number also in the land and mortgage register. Outside cities the district usually carries the name of the locality, for example Trzebnica. In cities it is often numeric: 6-04-03 in Warsaw, 090 in Gdansk, S-1 in Krakow.

You can also enter the full parcel identifier, for example 146518_8.0403.35, or coordinates. A postcode is not enough: land records do not recognise it, so we will then ask for the cadastral district.

What each layer of this check means

Layer values are available with Full access. Two grid rows, one for the substation and one for flexibility demand, also show the free part of the result.

  • Land records

    Parcel 303/13, cadastral district Chobanin, Wieruszów municipality, wieruszowski county, łódzkie voivodeship. Identifier 101807_5.0001.303/13.

  • Local spatial development plan

    The local spatial development plan at the checked point according to the national dataset. The dataset covers only some municipalities, so confirm the land use designation with the municipal office.

  • Nature protection designations

    All nature protection designations on the plot and around it, each with the name and straight-line distance. A designation outside the plot enters the result as something to check in the documents.

  • Flood hazard

    Whether the checked point lies within the hazard areas of the MZP and MRP maps in the checked dataset.

  • Mining area

    Whether the point lies within a mining area or a mining zone and, if so, which one: the name of the site, the mineral and the licence decision.

  • Nearest substation

    The nearest GPZ or NN substation from the substation register built from OpenStreetMap and land records, excluding substations marked as inactive or under construction. Name, OpenStreetMap code, operator substation code, operator and voltages are free, while straight-line distance, substation parcel and nearest address are in full access. Substation location: © OpenStreetMap authors.

  • Available capacity according to the operator’s list

    Available capacity shown by the operator for the row of its capacity list assigned to the parcel: according to the group to which the operator assigns the nearest GPZ, and if the substation is not assigned to a group, the nearest entry in the list. With the row name, assignment method and voltage, and queue saturation, i.e. the share of capacity reserved in the queue for this row in the total of reserved and available capacity. Next to the capacity for consumers from the Enea and Energa lists. This is geographical context, not confirmation of capacity for the project.

  • Connection application queue

    Total capacity of connection applications from a separate operator list, for a connection point or county: at PGE, Enea, Energa, Stoen and PSE, applications submitted, connection conditions issued and agreements concluded, generators only, with refusals separately, outside the total; at TAURON, the previous scope of the list. The breakdown by technology shows the same stages.

  • Transmission grid

    The nearest point on the PSE list and its distance from the plot. Over a long distance the match serves only as background, not as an indication of a connection point.

  • System pressure

    The nearest extra-high-voltage node with a redispatch signal, its distance and the date of the last signal. It is a proxy indicator for the node, not a measurement of curtailment for this substation.

  • Flexibility demand

    Does the operator publish flexibility demand at the substation closest to the parcel and what type: this is free. Capacity in MW, hours per year and the duration of each task are in full access. When we did not find an operator publication with the location of demand, the card states this directly, with the date of the check.

  • Renewable energy building permits in the municipality

    The number of RES projects with a building permit in the municipality is free. Total capacity in MW is available with Full access if it was specified in the decisions. No investor names.

  • RES listings for sale within 15 km

    How many RES projects and land listings are for sale nearby and their combined capacity. Seller names are excluded; marker locations are approximate.

  • Small MIOZE installations nearby

    Entries in the small installations register near the parcel: locality, technology, capacity and generator, and every generator leads to its company profile. The marker stands at the centre of the entry’s locality, because the register does not give the coordinates of the installation.

  • RES environmental decisions within 15 km

    RES projects for which an authority conducted proceedings on an environmental decision within this radius: the number, types, capacity from the applications and the distance to the nearest one. Proceedings do not mean the installation was built.

  • Energy cooperatives and clusters in the municipality

    Entries for the municipality in the register of energy cooperatives and in the register of energy clusters. Both are rare in Poland.

  • Transaction prices of land in the surroundings

    The number of transactions for undeveloped land within a 3 km radius over the last 60 months is free. Medians of the price per square metre for 24 and 60 months, as well as the list of transactions with date, price, and distance, are in full access. These are prices paid according to the Real Estate Price Register, not the valuation of this parcel and not the asking price.

  • PV potential

    Annual yield per kWp and the optimal angle according to PVGIS. The value is calculated for the nearest list point, so it is an approximation for the area, not a measurement on the plot.

What we check: eighteen layers from public registers

On the map you can see RES projects and land for sale, and the marker carries power. Click anywhere or enter an address or parcel number. For this point we will show the nearest substation from the substation register, the capacity declared by the operator for the listing row assigned to the parcel, connection applications from the operator's publications, the local spatial development plan, nature protection and flood risk. You will find the data status dates under the card. The first preview by address, plot number with the area or coordinates does not require an account. Subsequent previews require a free account. Paid values are unlocked by subscription.

You will find the substation lists and a comparison table in the tool available grid connection capacity.

The card does not create source data. It takes what the registers have published and calculates distances and matching to the operator's listing row for the specified point, with the source and date of status for each layer. An operator may provide capacity for a group of substations rather than for each individual substation; therefore, the nearest listing point does not necessarily correspond to the substation physically closest to the parcel. Consequently, the card assigns the listing row based on the group composition published by the operator, while showing the physical substation separately, from the substation register. The layers are arranged in three groups: whether the grid can accept it, whether the land allows it, and what is already happening in the vicinity. For the specified location, the card displays the layers that the location has in the dataset, and for the remaining ones, it states that the source did not respond.

LayerWhat it tells you
Land recordsIdentifying the parcel: cadastral district, municipality, identifier and geometry. Every subsequent layer starts here.
Nearest substationNearest GPZ or NN substation within 35 km: name, OpenStreetMap code and station code at the operator, operator, voltages, type and locality for free, and straight-line distance, parcel of the substation and nearest address in Full access. The register is not official: the card marks an operator inferred from the area with the word “probably”.
Available capacity according to the operator’s listThe capacity shown by the operator for the row of its list assigned to the parcel. The row is derived from the group to which the operator assigns the nearest GPZ; if the substation is not assigned to a group, then the nearest entry in the list, with straight-line distance and matching confidence: high for up to 10 km, medium for up to 35 km, and low for further distances. The date of the list and its expiry date are displayed next to the value.
Connection application queueHow many items are in the list row for this location and for what capacity: at PGE, Enea, Energa, Stoen and PSE, applications submitted, connection conditions issued and agreements concluded (including already connected sources) of generators, and refusals separately, outside the total; at TAURON the previous scope of the list. Available capacity without a queue tells half the truth.
Transmission gridThe nearest point in the transmission system operator’s available-capacity list and the straight-line distance to it. Over a long distance the match serves as background, not as an indication of a connection point.
System pressure at the EHV nodeRedispatch signals at the nearest extra-high-voltage node: how often the system asked generators to reduce output. This is system context, not a result for this parcel.
Flexibility demandDoes the operator report flexibility demand at the substation closest to the parcel, and of what type, free of charge; power, hours per year and duration of each task in Full access. The card reproduces the operator's publication and does not assess whether the installation can provide such a service.
Local spatial development planWhether the point lies within a local spatial development plan and its land use designation. Absence of a plan in the dataset is also a result that the card states explicitly.
Nature protection designationsSeven datasets of protection designations within 2 km of the point, with designation names and distances.
Flood hazardFlood hazard and risk maps for the point, identifying the scenarios that concern it.
Mining areaWhether the point lies within a mining area or a mining zone and, if so, which one: the name of the site, the mineral and the licence decision.
PV potentialThe annual yield from each kWp at the optimal angle. The value is calculated for the nearest point in the list, not for the coordinates of the parcel, and the card says so beside the row.
Renewable energy building permits in the municipalityThe number of RES projects with a building permit in the municipality is free. Total capacity in MW is available with Full access if it was specified in the decisions. No investor names.
RES listings for sale within 15 kmHow many RES projects and land listings are for sale nearby and their combined capacity. Seller names are excluded; marker locations are approximate.
Small MIOZE installations nearbyEntries in the small installations register within a radius of 15 km: locality, technology, capacity and generator, and every generator leads to its company profile. The marker stands at the centre of the entry’s locality, because the register does not give the coordinates of the installation.
RES environmental decisions within 15 kmHow many RES projects nearby went through proceedings for an environmental decision, split into photovoltaics, wind and biogas plants. Proceedings do not mean the installation was built.
Energy cooperatives and clusters in the municipalityWhether the municipality has an energy cooperative, an energy cluster or a direct line. Both are rare in Poland, so no entry is a normal answer.
Transaction prices of land in the surroundingsHow many transactions on undeveloped land were concluded within a 3 km radius in the last 60 months: this is free. The median price per square metre for 24 and 60 months with a range, and the list of transactions are in full access. The price paid, not the valuation of the parcel and not the asking price.

Charged separately, only if you want contact details from someone else’s listing

Unlocking another person’s listing is charged separately: PLN 49 net up to 25 MW (PLN 60.27 gross), PLN 389 net above that (PLN 478.47 gross); Full access with unlimited listing unlocks costs PLN 490 net/month (PLN 602.70 gross).

Frequently asked questions
How do I check a parcel for RES?

Enter an address or parcel number in the field at the top of the page or click a point on the map. For this point, we will show the nearest substation from the substation register, the capacity listed by the operator for the row of its capacity list assigned to the parcel, connection applications from the operator's publications, the local spatial development plan, nature protection and flood risk. You will find the data status dates below the card. This is public data organised into a single result, not an assessment of the project.

Where can I check available grid connection capacity for a parcel?

Available capacity is published by grid operators in lists of available capacity. On this page, we show the value from the operator's capacity list row assigned to the verified entry, together with the list date: according to the group composition provided by the operator, and when the substation is not assigned to a group, from the nearest list entry. The list row is a geographical context, not confirmation of capacity availability for a specific project.

How much does a RES parcel check cost?

The first check in a session is free and does not require an account if you enter an address with a house number, a commune and parcel number, a parcel identifier or coordinates. Paid fields on the card will then be obscured. A subsequent check requires a free account. Full numerical values are unlocked by a subscription, the price of which we provide during search and in the “Price and access” section.

Where does the parcel data come from?

From public registers: land records, grid operators’ capacity lists, the register of connection applications, the register of nature protection designations, local plans and flood hazard maps, with substation locations from OpenStreetMap (© OpenStreetMap contributors). We show the source for each layer, and the data status dates below the card.

Can I find a ready RES project or land for RES for sale?

Yes. The map shows RES projects and land listed on the platform, with capacity on each marker. Hover over a marker for a preview, then open the full listing from it, and the link above the map opens all listings.

How do I obtain the project price?

We do not publish prices on the map or cards. Agree the price directly with the seller after unlocking the listing.

Is the parcel check a legal opinion or investment recommendation?

No. The result organises public data for the checked point. No signal in one layer does not mean no risk in the project documents. HWW Hewelt Wojnowski Lindner i Wspólnicy sp.k., the platform’s legal adviser, provides legal analysis under a separate engagement. Ask HWW about reviewing your project documents.

How do I check a parcel if I only know its address, not its parcel number?

Enter an address with a house number. We convert it into a point and identify the parcel in land records that contains it. If it is not the correct parcel, enter the municipality and parcel number or click the correct location on the map.

Example result (parcel 303/13) uses the same sources: available capacity and queue come from Energa-Operator's lists, and substation and flexibility demand from the substation register as of 05.10.2026.

Dataset status: operator capacity lists, oldest operator publication 01.07.2026 · licences, MIOZE entries and the operator register: retrieval dates appear in the “Check a company” tool · RES building permit cases (GUNB), processed dataset 10.11.2026 · company profiles (KRS, VAT taxpayer register) 01.09.2026. GUGiK land records and GDOŚ nature protection designations are retrieved live for each check; the VAT status check date appears beside the company entry.

Land records, nature protection designations, local plans and flood maps are read directly from registers and may be incomplete; the card then states which source did not respond. The layer label describes the source response, not the quality of the parcel.

The parcel card is for initial screening. It does not replace connection conditions issued by the operator or an extract from a local spatial development plan, and is not tax or investment advice. Values in the examples on this page are illustrative. Data comes from public registers (URE, PSE, DSO, GUGiK, GDOŚ, KRS and MF), with a source alongside each figure and as-of dates in the card footer. The service is informational and does not provide legal advice. Operator: EFET Foundation · Platform legal adviser: HWW Hewelt Wojnowski Lindner i Wspólnicy sp.k.

The example result is a record of a historical reading with its sources and dates. We saved the result exactly as it came out, together with the source data file. The values are as at the day of the reading: operators’ lists change quarterly, and a local spatial development plan or a form of nature protection may appear at any time. A current check shows the layers available in the present card, together with the dates of their sources.
