Receiving conditions for connecting to the gas network or information on the possibility of connecting to the gas network is free of charge and does not oblige one to conclude a connection contract.

Documents required to receive the connection conditions:
  • A completed application for specifying connection conditions for a biogas plant, gas mine, or fuel gas regasification station – Connection Group C. Applications are available in Downloads below. 
  • If you do not have legal title to the property or facility that is to be connected, indicate in your application that “this application concerns the possibility of connecting to the gas network”. 
  • A map of the area at a scale of 1:1000 (1:2000) with the output point from the distribution system indicated
  • A map indicating the location of facilities at a scale of 1:25,000 (for applications from entities involved in gas extraction) 
  • An excerpt from the register of businesses of the National Court Register.
  • A declaration of legal title to use the facility or property
  • A power of attorney, if the application is submitted by the applicant’s attorney, unless this authorization results from the above-mentioned documents
Important: 
  • Confirm that the copies of the submitted documents are true copies. This can be done by a legal counsel, notary, or a person authorized to represent the applicant.

Fill out the application completely, providing all of the required information, and attach the above-mentioned documents; this will guarantee that the application will be processed within 90 days of submitting the complete application. 

You can submit the application in person, by mail (the list of our units is available here), or by sending a scan to [email protected]

We will check whether there are technical or economic conditions for connecting and, if necessary, issue connection conditions.
In the case of connecting sources, e.g., biogas plants or gas mines, we indicate in the connection conditions that:
  • You are required to build a fuel gas (biogas) treatment system and to install and operate a hygrometer and process chromatograph in order to measure the quality of fuel gas (biogas), including the sulfur content.
  • Fuel gas (biogas) that does not meet the quality requirements for fuel gases in the distribution network, in particular in terms of the minimum combustion heat, cannot be accepted into the distribution network; therefore a reverse system should be planned and built in order to reintroduce gas with unacceptable parameters into the treatment system.
  • The combustion heat of the fuel gas (biogas) introduced into the distribution network of Group E high-methane natural gas, which does not deteriorate the quality parameters of the gas in the distribution network, ranges from 38 to 41.6 MJ/m3; the Wobbe number ranges from 45.0 to 56.9 MJ/m3. 
  • In case the distribution system is supplied with fuel gas (biogas) that deteriorates the above-mentioned quality parameters of gas in the distribution system (i.e., the supply of fuel gas (biogas) with combustion heat lower than 38 MJ/m3), the procedures specified in the Distribution Network Code (DNC) are applied; in particular, we will charge fees in accordance with Point 6.8.1.3 in accordance with Point 25.10.2 of the DNC. 
  • We reserve the right to limit or temporarily suspend the collection of the declared amounts of fuel gas (biogas) in the case referred to in Point 6.8.1.4 of the DNC, as well as in cases where fuel gas (biogas) is supplied to the distribution system that does not meet the quality parameters specified in Point 6.8.6 of the DNC.
  • Introducing fuel gas (biogas) to the medium-pressure distribution network requires odorization; therefore, such a system is one of the elements necessary for connection.
The conditions for connecting to the gas network may be sent to you by mail to the correspondence address provided. You can also collect them (at our units or a selected gas supplier) in person or through a representative, provided that a power of attorney is presented, granted by the applicant listed on the application for specifying connection conditions. The list of our units is available here.
Documents needed to conclude a connection contract:
  • A completed application for a gas network connection contract The application is available in Downloads below. 
  • An excerpt from the register of businesses of the National Court Register
  • A declaration of the applicant’s legal title to use the facility or property
  • If the contract is signed on behalf of a business by a person who is not authorized in the National Court Register, also provide the original power of attorney for signing a gas network connection contract, a copy certified as a true copy by a person of public trust (e.g., a notary, counselor, or attorney-at-law), or an unconfirmed copy, if the power of attorney was granted in the form of a notary deed.

Important: 

Confirm that the copies of the submitted documents are true copies. This can be done by a legal counsel, notary, or a person authorized to represent the applicant.

You can submit the application in person or by mail (the list of our units is available here).

If you do not apply to us to conclude a connection contract within 30 days of receiving the conditions for connecting to the gas network, and at the same time:
  • some conditions for connecting to the distribution network have been defined and they would require the same technical capacity of the distribution system to be used
  • or some conditions for connecting to the gas network have been specified and relate to an area that coincides territorially in whole or in part,
then we conclude gas network connection contracts according to the order in which connection contracts signed by the customers are received, depending on the existing technical conditions (e.g., available capacity of the distribution system).
We will prepare a draft contract for connecting to the gas network for you. We can send it to you by mail to the correspondence address provided. You can also collect it (at our units) in person or through a representative, provided that a power of attorney granted by the applicant listed on the application for the purposes of concluding a gas network connection contract is provided. The list of our units is available here.

In the correspondence, we will specify the expiration date of the draft contract and we ask that you sign the contract within this timeframe. You can deliver a signed contract to us by mail or in person (at our units).

In accordance with the law, the connection fee due to PSG amounts to 100% of the actual expenditure on the connection. This fee, as indicated in the connection contract, is based on the estimated expenditure for the connection, which means that it may change after the investment has been completed. After signing a gas network connection contract, you will be required to pay 50% of the connection fee within 14 days of receiving the pro forma invoice. Detailed rules regarding the payment date for the connection fee are specified in the gas network connection contract.

The signed gas network connection contract is the basis for us and for you to start design, construction, and assembly work. As of the date the contract is signed, we reserve capacity in the distribution system in the amount listed in the conditions for connecting to the gas network.
On the date specified in the connection contract, you will be required to conclude a Technical Contract resulting from Points 7.4 and 10.1.6 of the Distribution Network Code. This contract will govern the terms of cooperation regarding the rules of:
  • transferring allocation data at the interface points of the systems,
  • providing telemetry and measurement data, 
  • preparing and agreeing on billing protocols, 
  • running and operating gas stations located at the interface of systems,
  • repairing and modernizing gas stations located at the interfaces of the systems,
  • exchanging information on planned investments which will affect the systems’ operating conditions,
  • cooperating in the event of low-quality fuel gas that affects the operation of the distribution system,
  • agreeing on emergency procedures, and
  • dealing with failures which affect the functioning of the distribution system. 
It is our responsibility to build network infrastructure elements such as a gas pipeline, gas stations, gas connections, and others in accordance with the connection conditions and within the timeframe specified in the gas network connection contract. As part of this stage:
  • we will prepare design documentation, obtain permits for entering the area, obtain the land for gas facilities, and secure all permits specified in the Construction Code and
  • we will build a network infrastructure along with the necessary activities to allow for its use. 

A detailed implementation schedule can be found in the gas network connection contract.

Meanwhile, you:
  • build networks and gas systems at your facility and install the equipment necessary to start supplying fuel gas to the distribution system, including a treatment system and a reverse system, and install a chromatograph and hygrometer in accordance with the issued connection conditions.

After the installation is completed, you will receive notification of completion and an invoice for the connection fee.
Fill out the Report on Readiness for Fuel Gas Filling and provide all required information. 

You can deliver the application to us by mail or in person (at our units). The list of our units is available here.
The condition for starting gas supply for new Pwej (input point to the distribution system), e.g., a biogas plant or gas mine, is:
  • Constructing gas networks and systems, including a treatment system and a reverse system, in accordance with the construction design and the requirements of the Construction Code,
  • installing a chromatograph and a hygrometer at the input point to the distribution system,
