Utility stocks rallied sharply after Inter RAO ($IRAO.MM) jumped 5.4% in early Moscow trading following reports that a drone strike causes fire at a power plant supplying electricity to Moscow. The incident raises fresh concerns over infrastructure risk, with ripple effects seen across utility shares and Russian blue chips.
Drone Strike Damages Moscow Power Plant, Utility Stocks React
Russian state utility Inter RAO ($IRAO.MM) surged 5.4% to RUB 5.92 as trading opened on November 23, after emergency services confirmed a significant fire at the Noginskaya GRES power plant east of Moscow. According to Reuters, emergency responders battled four hours to contain the blaze, which ignited around 3:00 local time after a suspected drone strike hit the facility’s generator hall (“Russia’s Inter RAO Jumps As Drone Hits Moscow Power Plant,” Reuters, 2025-11-23). Inter RAO is a leading supplier in the region, and the incident temporarily knocked out an estimated 1.4 GW of capacity—roughly 12% of greater Moscow’s peak demand (Bloomberg Energy Data, 2025). Power was restored to most affected districts by 9:30 a.m., but grid operator Mosenergo warned of potential rolling blackouts if further disruptions occurred.
This event is the largest grid-linked incident in the Moscow region since the 2023 fire at the Chagino substation. The incident has prompted an immediate review of physical and cybersecurity protocols across the Russian grid, as reported by the Interfax energy desk. Trading volume in Inter RAO shares more than doubled to 147 million, its highest single-session figure since July 2022 (Moscow Exchange data).
Broader Market and Energy Sector Implications Unfold
The sudden loss of generating capacity spurred volatility in wider Russian benchmarks. The MOEX Russia Index pared early losses to close up 0.7%, partially supported by utility and energy buys. Utility sector ETF — the FinEx Russian Utilities UCITS ETF (FXRU) — rose 1.9% by close, while major energy suppliers, including Rosseti ($RSTI.MM) and Unipro ($UPRO.MM), posted gains of 3.2% and 2.1%, respectively (Moscow Exchange data, 2025-11-23).
The oil and gas sector remained resilient, with Lukoil ($LKOH.MM) and Gazprom ($GAZP.MM) both slightly positive, up 0.4% and 0.5%. Analysts cited a reduced risk of major fuel supply disruption, as the Noginskaya GRES relies primarily on natural gas pulled from Rosneft’s ($ROSN.MM) local reserves (“Moscow Utility Plant Targeted in Latest Infrastructure Attack,” Bloomberg, 2025-11-23). But the incident did revive broader fears about regional grid security and knock-on effects for industrial production, especially ahead of Russia’s winter demand peak.
International market reaction remained muted, though Euro STOXX Utilities gained 0.3% on news flow, while traders watched potential supply risks to energy-intensive heavy industries. Western European electricity futures gained 1.1% for near-term delivery, as reported by EEX exchange. These cross-market ripples highlight infrastructure shocks’ potential to generate contagion far beyond the immediate blast zone.
Investor Strategies as Russian Utilities Face Infrastructure Risks
In the wake of the news that a drone strike causes fire at a major Moscow power plant, investors are recalibrating portfolios with renewed attention to infrastructure risk. Over the last year, Russian utility stocks lagged the MOEX by 4.5%, yet Inter RAO outperformed rivals, up 11% year to date before today’s surge (Bloomberg, 2025).
Value-oriented investors may see opportunity in sector pullbacks, particularly given the sector’s average price-to-earnings ratio of 7.9—still at a 16% discount to the broader market. Those with lower risk tolerance should actively monitor sector volatility and potential for regulatory responses, as Russia’s Federal Anti-Monopoly Service has flagged upcoming reviews of grid resilience since 2024.
Tactically, macro investors might diversify exposure using ETFs such as the FinEx Russian Utilities UCITS ETF (FXRU) or seek defensive positioning in international utilities, which could benefit from flight to safety. For more comprehensive stock market analysis, as well as recent geopolitical disruption coverage, ThinkInvest maintains detailed updates for informed decision-making.
Short-term traders can expect elevated volatility, as suggested by a 190% spike in 7-day implied volatility for $IRAO.MM options on the Moscow Exchange (MOEX Options Data, 2025-11-23). Investors should set stop-loss orders and revisit stress-test scenarios, particularly if grid attacks remain a pattern this winter.

Analysts Sound Off on Moscow Power Plant Attack Impact
Analyst commentary ahead of November 23 highlighted Russia’s ongoing exposure to critical infrastructure disruptions. Sberbank CIB warned in its October 2025 utilities sector outlook that “persistent security risks threaten supply-demand balances and could result in more volatile earnings.”
Meanwhile, Renaissance Capital’s utilities desk, in its November 2025 strategy note, projected Russian grid operators would step up cybersecurity and physical defense spending by up to 18% through 2026, raising operating costs but improving long-term sector resilience.
International market strategists, surveyed by Bloomberg, generally expect further attention to infrastructure hardening across both Russian and European grids. “We see utilities as defensive, but there’s increased attention to regional grid security as geopolitical threats elevate tail risks,” notes Bloomberg Intelligence senior energy analyst Jeffrey Avner.
Sentiment remains mixed for utilities and heavy industry, but sector rotation into defensive assets and select utilities is likely to continue near term, particularly if further incidents threaten power reliability during peak demand periods.
What the Drone Strike Means for Investors Going Forward
The latest incident, in which a drone strike causes fire at a power plant supplying Moscow, elevates infrastructure security risk as a key investment consideration in Russian utility and energy stocks. Investors should anticipate continued volatility and potential sector premiums for utilities able to rapidly boost resilience.
Heightened risk offers tactical entry points, especially for those willing to weather swings, but underscores the critical nature of ongoing surveillance and position reassessment. For continuous data-driven updates, follow ThinkInvest’s financial news coverage.
