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.

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 draft TGDP for 2023–2032 brings the first major technological revolution in line with patterns from highly developed power systems with a large share of RES in the generation mix. It is the construction of an HVDC line connecting the north and south of Poland. The aim of the project is to be able to send electricity from the north of the country, generated by onshore and offshore wind sources, to the south of Poland, to the industry located there. An alternative to this project would be an extension of the 400 kV network line, with significant and costly constraints.

The draft TGDP for 2023–2032 is the result of several years of experience in applying innovative technical and economic analyses, to the transmission grid project planning. The methods and computational tools used in the development of the previous edition of the TGDP were used to create it. The outline of the set of grid projects was preceded by a fundamental scenario analysis of the development of the environment and the interior of the power system. It was all with the aim of selecting projects that would contribute to the security of power supply to consumers under all conditions.

The projects presented in the draft TGDP are intended to support the following:

  • the commitments 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 2023–2026 capacity market auction,
  • improvement of power supply conditions, including minimisation of network 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 TGDP for 2023–2032, legal considerations 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.

Planned capital expenditures, including the number of investments, 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, we included 260 investment tasks for the expansion and modernisation of the transmission grid. The estimated value of the planned expenditure for all investments for this period is approximately PLN 35.9 billion.

Systemic effects to be achieved as a result of the implementation of the investments by 2032 and by 2036 

Implementation of infrastructure investments

Network investment portfolio

In 2021, PSE periodically updated the Investment Portfolio, which is one of the main tools for managing investment projects. .

PSE's Investment Portfolio is a collection of network infrastructure investment projects grouped into investment programmes. All investment projects included in the Network Investment Portfolio are grouped into investment programmes according to the strategic importance (strategic programmes), the location and interdependence of the projects (area programmes), and the nature of the work supporting the implementation of the remaining investment projects (e.g. investor deliveries, formal and legal issues). In special cases, affiliation of projects other than those related to network infrastructure is allowed.

The Network Investment Portfolio includes 5 strategic programmes and 5 area programmes (as at 25 January 2022):

Programme 1.
The strategic programme "Power output system from Kozienice Power Plant and improvement of power supply conditions in north-eastern Poland": 13 investment projects.

Programme 2.
The strategic programme "Power output system from Turów Power Plant and improvement of power supply conditions in south-western Poland": 16 investment projects.

Programme 3.
The strategic programme "Power output system from Dolna Odra Power Plant and RES and improvement of power supply conditions in north-western Poland": 17 investment projects.

Programme 4.
The strategic programme "Power output system from RES and improvement of power supply conditions in the northern Poland - eastern part": 24 investment projects.

Programme 5.
The strategic programme "Power output system from Bełchatów Power Plant and improvement of power supply conditions in central Poland": 28 investment projects.

Programme 7.
“South” Area Programme: 27 investment projects.

Programme 8.
Area Programme "Formal Completion of Investments." 14 investment projects.

Programme 9.
Strategic Programme "Building submarine connections and energy storage facilities." 2 investment projects.

Programme 10.
“Investor's Deliveries” Area Programme: 18 investment projects.

Programme 11.
The strategic programme "Power output system from RES and improvement of power supply conditions in the northern Poland - western part": 10 investment projects.

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

Of the 169 investment projects implemented by PSE, 72 investments implemented in December 2021 were given priority 1. Projekty priorytetowe definiowane są jako najważniejsze dla zapewnienia bezpieczeństwa pracy systemu elektroenergetycznego. Ich realizacja umożliwi przyłączenie i wyprowadzenie mocy z obecnie budowanych źródeł wytwórczych oraz jej przesyłanie do odbiorców.

Examples of priority investments implemented under investment programmes 

Priority 1 investment projects are implemented under the following investment programmes: 

Strategic Programme 1 ─ "Power output system from Kozienice Power Plant and improvement of power supply conditions in north-eastern Poland" 
The objective of implementing the investment projects included in Programme 1 is to ensure reliable power output from Kozienice Power Plant following its extension with a new 1,000 MW power unit and to improve the reliability of power supply in the northern and north-eastern parts of the Polish Power System and Warsaw agglomeration.
