Tauron (PLTAURN00011) was trading at EUR 2.08 at Lang & Schwarz on October 8, 2026 at 1:37 p.m. CEST, down 0.48 percent versus the prior close of EUR 2.09. The company had planned a Siersza transformation with up to PLN 3.5 billion of investment and up to 800 MW of new capacity, according to BIZNES24 on September 23, 2026.

Three milestones and their figures

On March 30, 2026, Tauron published its annual reports; its 2025 sales were PLN 33.3 billion, a figure reported by BIZNES24 on September 23, 2026. On September 9, 2026, Tauron reported first-half sales of PLN 17.201 billion, up 3.00 percent from PLN 16.643 billion a year earlier, according to TAURON. On September 23, 2026, the Siersza plan added a second quantified investment track, covering up to PLN 3.5 billion and 800 MW.

What does Siersza add?

The proposed portfolio includes a gas power unit of about 630 MW, large-scale energy storage, solar installations and waste processing, according to BIZNES24. The company said existing coal units could operate under current arrangements through the end of 2027, with possible continuation into 2028 subject to a capacity-market contract and regulation.

The investment case therefore combines replacement capacity with grid flexibility rather than relying on one generation technology. That matters because Tauron's first-half 2026 operating profit weakened even as sales increased: the group reported PLN 3.697 billion of EBITDA, down 12.00 percent year over year, while its EBITDA margin fell to 21.40 percent from 24.40 percent, according to TAURON.

Next reporting date

TAURON's investor-relations calendar lists November 18, 2026 as the date for its third-quarter 2026 results. The same calendar records September 9, 2026 as the first-half results announcement, giving the next report a clear scheduled comparison point.
