ECONOMIC AND MARKET IMPACTDevelopment of the transmission system

The basis for the sustainable development of the national economy is to provide the necessary amount of electricity to all consumers. We are committed to ensuring that the transmission system provides a reliable electricity supplies both now and in the future. It is our responsibility.

Development of the transmission system

The Transmission Grid Development Plan (TGDP) defines transmission grid development projects, the implementation of which is expected to ensure that the national demand for capacity and electricity is met in the long term. The main factors influencing the directions of the transmission grid development include: the increase in electricity demand, the development of generation sources, and the need to increase the usage of cross-border connections.

The TGDP for 2023–2032 includes the first technological revolution in line with patterns from highly developed power systems with a large share of RES in the generation mix. This refers to the construction of an HVDC line connecting two clearly defined areas of Poland – north and south. The objective of this project is to enable the transmission of energy from onshore and offshore wind sources from the north of the country to industrial facilities located in southern Poland. . The alternative to this project – involving significant and costly limitations – would be the expansion of the 400 kV network.

The TGDP for 2023–2032 was developed on the basis of several years of experience in applying innovative technical and economic analyses, including probabilistic methods, to the transmission grid investment planning. In developing it, the methods and calculation tools developed in the previous edition of the TGDP were used. Outlining a set of investment projects in the grid was preceded by a fundamental analysis of the scenarios of development of the environment and the interior of the power system in order to select projects contributing to the security of power supply under all conditions.

The projects presented in the TGDP for 2023–2032 are intended to support the following:

  • the commitments of the Republic of Poland to achieve the national target for the share of energy from RES in final energy consumption,
  • the government's plan to build offshore wind farms in the Baltic Sea,
  • the government's plan to build nuclear capacity,
  • the connection of new generating units in accordance with the results of the 2023–26 capacity market auction,
  • improvement of power supply conditions, including minimalization of congestion in the entire system – particularly in the context of the planned construction of renewable (wind) sources in northern Poland – both off and on the shore.

In preparing the 2023–2032 TGDP, legal conditions resulting from the following were taken into consideration:

  • concept of spatial development of the country,
  • voivodeship spatial development plans,
  • Poland's Energy Policy,
  • ENTSO-E TYNDP 10-year development plan,
  • performance of connection agreements and specified conditions for connection to the transmission grid,
  • performance of other obligations, including arrangements with the DSO,
  • EU regulations.

Podstawą sporządzenia PRSP 2023-2032 były uwarunkowania określone w Polityce energetycznej Polski do 2040 r. (zatwierdzona przez Radę Ministrów 2 lutego 2021 r.), a także w Krajowym Planie na Rzecz Energii i Klimatu na lata 2021-2030 (KPEiK) i Programie polskiej energetyki jądrowej (PPEJ). Założenia z nich wynikające zostały uzupełnione o aktualny stan wiedzy naszej organizacji na temat możliwych kierunków przyszłych zmian w sektorze elektroenergetycznym. W ocenie PSE, uzupełnienia te pozostają spójne z kierunkami określonymi w wymienionych dokumentach, zakładających, że w KSE w najbliższych kilkudziesięciu latach dokonają się istotne zmiany strukturalne.

Worth knowing

By 2040, the total net available capacity of generating sources is projected to increase (collectively to above 60 GW for PEP and PNPP, and above 70 GW for NECP). The role of coal-fired system units will be reduced. There will be a significant increase in the share of RES (mainly wind and solar power plants) in electricity generation, to the level of about 32 percent in 2030 and 40 percent in 2040. A significant increase in the share of gas units is also expected.

All the aforementioned documents are consistent on the timing of the nuclear power program. They assume that the first power unit of the nuclear power plant will be put into operation in 2033, with subsequent units to follow in successive years. A description of national strategic documents on the energy sector development is provided in Chapter 3 of the 2023–2032 TGDP.


Planned capital expenditures until 2032 and 2036, including the number of investment projects and the construction and modernisation of EHV lines

In the Development Plan for Meeting the Current and Future Electricity Demand for 2023–2032 in the perspective of 2036, 252 investment tasks for the expansion and modernisation of the transmission grid are planned. The value of the planned expenditure for all investment projects for this period is estimated approximately at PLN 35.9 billion.

According to the Investment Project Plan for 2023–2027 approved on January 26, 2023, as a result of updating the estimated values of the projects, the value of the planned capital expenditures in 2023–2027 will be PLN 24.0 billion, and in 2023–2036 it will increase to about 61.8 billion.

Implementation of the planned investment projects will bring measurable effects. The system effects until 2032 and 2036 are shown in the table below.

Implementation of infrastructure investments

Network investment portfolio

For the purpose of the more effective implementation of investment projects in 2022, PSE periodically updated the Investment Portfolio, which is one of the main tools for managing investment projects. The projects entered into the Investment Portfolio are subject to grouping, categorisation, prioritization and determination of the order of their implementation, taking into account in particular the system conditions related to the possibility of the required outages of transmission network elements.

All investment projects included in the Network Investment Portfolio are grouped into investment programs based on:

  • strategic significance,
  • location and interdependence of projects,
  • the nature of works supporting the implementation of other investment projects (example: investor’s deliveries, formal and legal issues).

As of July 2023, the Network Investment Portfolio includes eleven Programmes under which a total of 191 investment projects are being implemented.

Programme 1.
“Power output system from the Kozienice Power Plant and improvement of power supply conditions in north-eastern Poland”: 23 investment projects.

Programme 2.
“Power output system from the Turów Power Plant and improvement of power supply conditions in south-western Poland”: 21 investment projects.

Programme 3.
“Power output system from the Dolna Odra Power Plant and RES, including improvement of power supply conditions in north-western Poland”: 21 investment projects.

Programme 4.
“Power output system from RES and improvement of power supply conditions in the northern Poland – eastern part”: 21 investment projects.

Programme 5.
“Power output system from the Bełchatów Power Plant and improvement of power supply conditions in central, eastern and north-western Poland”: 25 investment projects.

Programme 6.
“Adaptation of facilities and devices to the requirements of the Regulation establishing a network code on electricity emergency and restoration (NC ER)”: 2 investment projects.

Programme 7.
"South”: 26 investment projects.

Impact on employment in various sectors of the economy and on Poland's economic growth

Of the 186 investment projects implemented by PSE, 88 investment projects implemented in December 2022 were given priority 1. Priority projects are defined as the most important for ensuring the operational security of the electric power system.
