A 4850 km track of new 400 kV lines, 28 new and 110 modernized substations and an onshore DC line are part of the investment plans of Polish grid operator – Polskie Sieci Elektroenergetyczne PSE – until 2034. On Friday, March 15, the company presented for consultation a draft “Development Plan for Meeting Current and Future Electricity Demand for 2025 – 2034” (Transmission Network Development Plan, PRSP).

The document includes variant scenarios for the development of the National Electricity System, plans for the expansion of transmission infrastructure and the results of generation resource adequacy analyses. Following consultations, the document will go to the President of the Energy Regulatory Office for agreement, and will then be the basis for PSE’s investments.

– The implementation of the projects presented in the PRSP is an essential element of Poland’s energy transition, and will ultimately allow our country to achieve climate neutrality by 2050. The planned investments are a response to the dynamic changes taking place and will allow us to prepare the grid for them – says Grzegorz Onichimowski, President of the Management Board of PSE.

The PRSP takes into account the ongoing structural changes in the National Electricity System, such as the progressive electrification of heating and transportation and the emergence of new large electricity consumers, which will significantly affect the increase in demand for electricity and power in the system.

The development of the transmission network outlined in the document will provide a solid basis for carrying out changes in the National Electricity System’s environment caused by the energy transition process. It will also enable the connection of new generation units, including renewable and nuclear sources. Among other things, it will allow up to about 18 GW of offshore wind power, 45 GW of photovoltaic power plants, more than 19 GW of wind farms and the connection of a nuclear power plant in Pomerania, as well as the commissioning of small nuclear reactors. One of the most important projects in the development plan is the construction of a direct current connection (HVDC), linking the north to the south of the country. This will make it possible to send power from new generation sources to consumers without putting a strain on the rest of the transmission network.

The total estimated investment planned by PSE is about PLN 64 billion by 2034.

Comments on the development plan should be submitted by April 5 to the following email address: konsultacje-PRSP@pse.pl using the form available on the website at this link.
