Electricity market: The 2023 Redispatch Report from the President of URE
The President of URE (Energy Regulatory Office) has authored a report on Polish electrical power redispatch in 2023
The obligatory annual redispatch reports from regulatory authorities were introduced by the EU Regulation on the internal market for electricity[1]. The redispatch reports are developed for use by various audiences, including The Agency for the Cooperation of Energy Regulators (ACER).
Prepared for the first time by URE as the Polish regulatory authority, the 2023 Redispatch Report is based on reports submitted by the transmission system operator (TSO), Polskie Sieci Elektroenergetyczne, and distribution system operators (DSOs)[2]. The Redispatch Report details the types of redispatch used by TSOs and DSOs, data detailing the energy quantities and types of energy sources subject to the Redispatch Report procedure — without the balancing market[3] — and information on the measures pursued to reduce the required reduction of the generation output from renewable sources and cogeneration in the future.
2023 redispatching in Poland.
In 2023, Polskie Sieci Elektroenergetyczne issued to power generators and operators and accepted market and non-market redispatch orders. However, this focused on both reduction and increase of generated power outputs. The redispatch orders applied to cross-border electricity transmission.
The redispatch of units not on the balancing market ordered and accounted for under GGS contracts[4] includes increased generation orders with a total volume of nearly 20.65 GWh and reduced generation orders for more than 9.24 GWh.
The cross-border redispatches to reduce the load on grid components, involving increased generation and energy exports to Poland’s neighbours, covered a total of 4.65 GWh.
In contrast, cross-border export balancing redispatches (increased generation) and import balancing redispatches (reduced generation) were nearly 234.05 GWh and more than 25.31 GWh, respectively.
The TSO also applied non-market redispatch in 2023, which was reduced RES generation, with a total of 66.07 GWh, of which nearly 41.82 GWh was from wind power.
DSOs voluntarily applied non-market RES redispatching for a total volume of 4.16 GWh in 2023, of which nearly 3.23 GWh from PV installations. Only three out of nearly two hundred DSOs used this procedure last year.
Measures to reduce required redispatching
According to the Report, the measures implemented in 2023 to reduce the number of required generation output instances among RES and high-performance cogeneration units included the preparation for the second stage of the Polish balancing market reform.
The Report indicates the following as being necessary to reduce the required distribution system-enforced redispatching:
- DSO grids of all voltage levels need to be expanded, along with their capability of handling RES, and service connections for EV charging utilities;
- a flexibility service catalogue needs to be established and cast in an implementing regulation and the TNC[5];
- the equipment in operation requires enhanced supervision for the monitoring of the grid status and electricity and power flows;
- IT systems for DSO operational support need to be streamlined, especially for assisted flexibility service purchasing decisions.
The President of URE will produce and publish the Redispatch Report every year from now on.

[3] The balancing market features no redispatch as construed under Article 2(26) of Regulation 2019/943, as the generation units are dispatch controlled by the TSO under the work plans established as part of the scheduling process.
[4] They are contracts for Grid-enforced Generation Services concluded between a TSO and an NCDGU (Non-Centrally Dispatched Generation Unit). A GGS contract ensures the generation of electricity by the NCDGU required for the proper operation of the National Grid.
