At the transmission level, the Energy Law Act (Prawo Energetyczne) imposes an obligation on the PSE company, the TSO, to prepare and publish information concerning, among other elements, the values of available connection capacity for transmission substations or groups of substations operating at and above nominal voltages of 110 kV, as well as the planned evolution of these values over the subsequent five year period from the date of publication, as presented in the Transmission Grid Development Plan (PRSP), which is available on PSE’s website.

PSE is required to update this information at least monthly and to publish it on its website, while also making it available for public inspection at its headquarters.

New conventional system scale generation sources with single unit capacities currently exceeding 500 MW require a dedicated approach to their integration into the transmission system. Decisions regarding the conditions and feasibility of their connection, given the current state of development of the National Power System (KSE), will be taken based on individual applications and case specific analyses performed by PSE.

Currently, at the distribution level, DSOs publish available capacities in the power grid (voltage above 1 kV) in accordance with Art. 7, item 8l, sub-item 2 of the National Energy Law Act: 8l. An energy company involved in the transmission or distribution of electricity is required to prepare information on: 

• Entities applying for connection of energy sources to the power grid with a rated voltage higher than 1 kV, location of connections, connection capacity, type of installation, dates of issue of connection conditions, conclusion of grid connection agreements, and commencement of electricity supply.

• The total available connection capacity for energy sources, as well as planned changes to these values over the next 5 years from the date of their publication, for the entire network of the company with a rated voltage above 1 kV, divided into power stations or groups of power stations forming part of the network with a rated voltage of 110 kV and above. The total connection capacity is reduced by the capacity resulting from the issued and valid conditions for connecting sources to the power grid and by the amount necessary to ensure electricity generation from offshore wind farms corresponding to the capacity referenced in Article 14(1) and Article 29(3) of the Act of 17 December 2020 on the promotion of electricity generation in offshore wind farms, in compliance with the provisions on the protection of classified information or other legally protected information.

The company shall update this information at least once a quarter, considering the expansion and modernisation of the network and the connections that have been and are being implemented, and shall publish it on its website.

ENEA Operator sp. z o.o. (hereinafter: ENEA Operator or the Company) prepares and publishes information concerning, among other things, the total available connection capacity for sources, as well as planned changes to these values over the next 5 years, for the entire ENEA Operator network with a rated voltage above 1 kV, divided into power stations or groups of power stations included in the network with a rated voltage of 110 kV and above.

The total available connection capacity volumes were determined for separate areas defined by HV/MV substations. The values obtained were reduced by the connection capacities of sources planned for connection, including sources for which:

• A contract for connection to the network has been concluded

• Connection conditions have been issued and have not expired

• The connection is being processed in accordance with the rules set out in Article 7(9) of the Energy Law

• Proceedings have been initiated with the President of the Energy Regulatory Office (URE) regarding the refusal to conclude a connection agreement

The network structure reflects the changes planned for implementation by 2030 on the basis of the Company’s development plan, agreed by the President of the Energy Regulatory Office in terms of meeting current and future electricity demand for the years 2023–2028.

The connection capacity values for sources provided in this information are estimates for each area and are not evenly distributed across individual points within the designated areas. The power distribution depends on the structure of the distribution network, the existing load, and the current and modified load capacity of the cables as a result of network modernisation. Regarding the expected situation in the final year of calculations, the connection power values and the distribution of this power also depend on the implementation of the currently planned development of the power system by both ENEA Operator and the TSO. The available connection capacities from the ENEA Operator’s area, taking into account the connected capacities and the energy sources expected to be connected, are presented in tabular form (on the map).
