Polish Power Plants Show Resilience Amidst Heatwaves
Recent heatwaves have tested energy systems across the globe, and Poland’s power infrastructure is no exception. Despite soaring temperatures, the national energy system has demonstrated remarkable resilience, a fact confirmed by Tobiasz Adamczewski, Vice President of Forum Energii. This stability is, in part, a testament to the significant advancements in renewable energy sources (RES) within the country.
National Grid Stability Despite Challenges
The Polish Transmission System Operator (PSE) recently issued a “recall period” for the capacity market, a mechanism to ensure sufficient power supply during peak demand (specifically from 5 PM to 7 PM). This action, however, did not escalate to the implementation of power supply restrictions—a measure last employed over a decade ago in 2015. This indicates that Poland’s power plants have successfully navigated a natural stress test under extreme weather conditions.
Tobiasz Adamczewski, in comments provided to the Polish Press Agency (PAP), underscored this positive outlook:
“If the situation were worse, we still have other tools in the form of power supply restrictions. The operator is not resorting to these restrictions, which signifies a stable situation.”
This resilience is particularly noteworthy given that the operations of two key power plants, Kozienice and Połaniec (both operated by Enea), which rely on water cooling from the Vistula River, were temporarily limited due to the prevailing high temperatures affecting water levels and cooling efficiency. Such limitations highlight the critical challenges conventional power generation faces during heatwaves.
Renewable Energy: A Cornerstone of Resilience
Intriguingly, one of the primary factors bolstering the Polish power plants’ resistance to heatwaves is the increasing adoption of renewable energy technologies. The continuous growth of solar photovoltaics since 2015 has been instrumental, with solar power significantly contributing to meeting daytime energy demand. This reliance on solar energy during sunlit hours reduces the strain on traditional power plants, especially when cooling resources are scarce.

Looking ahead, future energy demands are expected to be met through a combination of energy storage solutions and the burgeoning development of offshore wind farms. These technologies are poised to provide crucial stability and supply flexibility to the grid.
Adamczewski further elaborated on the future role of renewables:
“In the future, we will also have offshore wind energy, which is currently under construction and should supply energy to the system even at night. Night-time energy is often cheaper and should be stored to cover evening peak demands in summer, on days when solar energy is immediately consumed.”
While the overall system demonstrates robust health, it’s important to acknowledge that occasional, localized grid overloads may still occur in the coming years. However, these are not expected to compromise the functionality of the entire energy infrastructure.

Frequently Asked Questions (FAQ)
Heatwaves can significantly impact conventional power plants, especially those that rely on water for cooling. Elevated water temperatures or reduced water levels in rivers and lakes can limit their operational capacity, as seen with plants cooled by the Vistula River in Poland. This makes it challenging to dissipate excess heat, potentially forcing power plants to reduce output or even shut down to prevent damage.
Renewable energy sources, particularly solar photovoltaics, play a crucial role in mitigating the challenges posed by heatwaves. During sunny days, solar power can significantly meet daytime energy demand, reducing the reliance on traditional power plants that might be under stress. This diversifies the energy mix and lessens the burden on water-intensive cooling systems, enhancing overall grid resilience.
Power supply restrictions, also known as rolling blackouts or demand-side management, are measures taken by grid operators to reduce electricity consumption during periods of extreme demand or supply shortages. They are typically avoided because they disrupt daily life and economic activity. The fact that Poland’s grid operator did not need to implement these during recent heatwaves indicates a robust and stable energy system capable of managing demand spikes.
Energy storage solutions, such as large-scale batteries, allow excess renewable energy generated during off-peak hours (like cheap night-time wind energy) to be stored and released during peak demand, such as summer evenings. Offshore wind farms provide a consistent source of power, often generating electricity even when solar output is low or non-existent, especially at night. Together, these technologies offer greater flexibility, reliability, and independence from fossil fuels, enhancing overall grid stability and reducing vulnerability to extreme weather events.
