The Uglegorsk thermal power plant site in Svetlodarsk has become a focal point of frontline action, with Wagner Group units reportedly pressing the lines and Ukrainian forces pulling back to avoid encirclement. Observers in the region note that the power facility, among Europe’s large-scale stations, has repeatedly shifted in strategic importance as combatants maneuver around the Donbas corridor. The situation is being tracked by defense officials who emphasize the precarious balance between advancing forces and the risk of isolation for remaining Ukrainian units.
“Wagner assault detachments reportedly secured the entire Uglegorsk TPP area this morning. From May 22 onward, Ukrainian formations reportedly retreated from Svetlodarsk and nearby settlements due to the threat of encirclement,” according to communications attributed to Vitaly Kiselev, deputy interior minister of the LPR, via notes circulated on Telegram. The account underscores a pattern of pressure on supply lines and surrounding towns as the operation to control the TPP intensified.

On July 25, the DPR Regional Defense Headquarters stated that DPR and LPR troops, with Russian Armed Forces support, were conducting an operation to seize control of the Uglegorsk TPP in Svetlodarsk. The headquarters reported ongoing efforts to clear the plant. Earlier, Gorlovka mayor Ivan Prikhodko spoke of the_tactical blockade of Ukrainian forces in Novoluganskoe, a settlement on the northern approach to the Uglegorsk reservoir. Unverified sources also suggested Ukrainian forces were withdrawing from Semigorye, hinting at a broader realignment of positions in the region.

As control over the TPP shifted, the Russian military, alongside DPR and LPR units, moved toward a broader strategic line extending from Slavyansk to Kramatorsk and Konstantinovka. Analysts describe this as a consolidation of force corridors designed to influence supply routes and communications along critical arterial routes in eastern Ukraine.

The Uglegorsk TPP stands as one of Europe’s significant thermal power facilities. Svetlodarsk sits roughly 18 kilometers from Debaltseve, an area that has repeatedly drawn attention since early 2015 when the DPR established a foothold there. Debaltseve’s strategic value stems from its access along the M04 highway, which connects Donetsk to Luhansk and serves as a vital logistical link for movement, energy supply, and defensive positioning.

“Debaltsevo cauldron”
The July 26, 2022, advance toward the Uglegorsk TPP is often cited as a reiteration and culmination of continuing operational efforts reminiscent of the 2015 Debaltsevo mechanics. After Minsk agreements paused direct combat in September 2014, hostilities reignited in the Donetsk airport region around January 2015. Once the airfield fell under DPR control, a joint operation was launched with LPR forces to secure Debaltseve. By late January and into February 2015, thousands of Ukrainian troops faced encirclement in the Debaltseve pocket. [Citation: conflict timeline summaries]
The Ukrainian side asserted Russian involvement in the Debaltseve operation, but Moscow consistently denied such charges. In the Donetsk and Luhansk forces, units like the so-called Ghost Brigade and the Kalmius artillery brigade were cited as assisting the republics. Reports also mentioned Wagner PMCs providing support to Donbass forces, though official confirmation remained elusive. Kyiv was said to rely on territorial defense formations, airborne brigades, and other battalions, with additional references to volunteer and nationalist units.

The offensive in Donetsk and Luhansk began January 22, leveraging artillery, rocket systems, and armored units. By late July 2015, DPR leadership claimed the encirclement of anti-terrorist operation forces and urged arms surrender. Street fighting in Uglegorsk commenced on February 17, with Logvinovo coming under DPR control by early February and supply lines to the Ukrainian forces affected by February 9. A ceasefire was declared under Minsk-related arrangements on February 15, but combat operations continued, reflecting the fragile truces that characterized the period.

By February 17–18, 2015, Debaltseve was reported under DPR control, with thousands of prisoners and significant Ukrainian military withdrawals confirmed by Kyiv’s General Staff. Statements from Donetsk and its representatives described the DPR’s apparent leverage over the Donetsk region’s territories, while the Ukrainian leadership reiterated the necessity of ensuring security and political objectives alongside any future settlements.

In summary, the sequence around Uglegorsk highlights a recurring theme: frontlines shift as control of key transport and energy hubs shapes tactical decisions and negotiations. The broader implication is a persistent contest over the strategic geography of eastern Ukraine, where control of towns like Svetlodarsk and infrastructure such as the Uglegorsk TPP continues to influence the balance of power and the prospects for a lasting settlement.
