Conditions arising from the Energy Policy of Poland (EPP)
Along with the possible adoption of PEP2040, “Energy Policy for Poland until 2030” issued in 2009 and the “Energy Security and Environment - 2020 Perspective” Strategy of 2014 will be repealed. The main considerations for PRSP 2021-2030 under the draft PEP2040 provide for network expansion which allows to:
- evacuate power from the existing generating sources,
- connect new capacity, including nuclear units and onshore and offshore wind farms at a level that allows the required RES share to be achieved in the energy balance of the country,
- improve the reliability of power supply to consumers,
- create secure conditions for operation of intermittent sources in coordination with other PPS elements,
- provide capacity for power exchange with adjacent systems,
- increase the energy efficiency of electricity transmission.
Considerations arising from the Ten-Year Network Development Plan (ENTSO-E TYNDP) 2018
Every other year ENTSO-E publishes a Community-wide ten-year network development plan. The current Community-wide Network Development Plan was published in November 2018. The main objective of the investments included in TYNDP is to achieve the European climate targets by 2050 in a cost-effective manner, maintain operational security of the power system, taking into account the economic, political and social needs under conditions of uncertainty of future infrastructure development. The development needs in the European power system, identified in the course of analyses conducted in the TYNDP 2018 creation process arise, among other things, from a dynamic development of renewable energy sources (mainly wind), energy storage technologies, electromobility, heat pumps, and the need to reduce CO2 emissions.
TYNDP 2018 provides for six clusters of projects concerning the development of the national transmission network and cross-border interconnections.
PRSP 2021-2030 includes all investment projects within the territory of Poland provided for in TYNDP 2018 during the period ending in 2030.
Considerations arising from the implementation of connection agreements and defined conditions for connection to the transmission network
As at 2 December 2019, PSE had connection agreements signed for new generating units with a total capacity of 14,774.975 MW, including 10,785 MW for conventional generating units and the remaining capacity for RES (4,717.975 MW). PSE also has concluded connection agreements for distribution systems with a total capacity of 149.5 MW and power plant auxiliary transformers with a total capacity of 331.7 MW.
Our company has issued connection conditions for:
- RES with a total capacity of 5,163 MW,
- conventional energy sources with a total capacity of 2,754 MW,
- a distribution system with a capacity of 30 MW,
- power plant auxiliary transformers with a total capacity of 95 MW,
- energy storage facilities with a total capacity of 312 MW.
Considerations arising from the fulfilment of other commitments, including arrangements with DSOs
The 400 and 220 kV national transmission network together with a large part of the 110 kV distribution network operates in the multiple-feed meshed network configuration. One of the key aspects in planning the development of transmission infrastructure is to ensure the cohesive and coordinated development of the entire meshed network both at the EHV network level and the 110 kV network level . This approach makes it possible to ensure long-term operational security of the PPS and optimal, in technical and economic terms, dimensioning of needs for network expansion in different areas. This issue is provided for in the applicable laws and regulations, including the Energy Law (Article 9c(2)(5)) and the Transmission Network Code (Conditions for the network use, operation, maintenance and development planning - Section 3).
As a result of integrated planning of the development of the EHV and 110 kV closed network, in order to improve the reliability of power supply to different DSO areas, the TSO and DSOs have agreed and concluded or are in the course of concluding respective agreements addressing the need to strengthen the existing and construction of new connections of the 400 and 220 kV transmission network connections with the 110 kV network.
Integrated planning requires multi-variant analyses of an iterative nature for the entire meshed network, taking into account changing system conditions. In the run-up to the drafting of PRSP 2021-2030, analyses were completed concerning the EHV and 110 kV meshed network operation concept in the operating areas of TAURON Dystrybucja S.A., PGE Dystrybucja S.A. and ENERGA Operator S.A. At the same time, analyses for the areas of ENEA Operator Sp. z o.o. and Innogy Stoen Operator Sp. z o.o. were also in progress.
Conditions arising from EU regulations
Article 16(8) of Regulation (EU) 2019/943 of the European Parliament and of the Council imposes the obligation on TSOs to make available to market participants, from 1 January 2020, cross-zonal capacity of not less than 70 percent of the transmission capacity for the border concerned (Coordinated Net Transmission Capacity, CNTC approach) or a critical network element (Flow-Based Allocation, FBA approach) determined respecting operational security limits. Analyses conducted by the PSE have shown that the provision of transmission capacity at the required level will require measures to eliminate related congestions. In implementing the provisions of the Action Plan (prepared by the Government pursuant to Article 15 of Regulation 943), PRSP 2021-2030 takes into account relevant network investments aimed to eliminate barriers related to cross-border exchange in the above-mentioned context.
