Talen Energy Could Rally 32% as AI Data Centers Strain the Power Grid

Talen Energy just got a bullish new call from Wall Street built entirely on one theme: electricity is becoming the real bottleneck in the AI boom, and Talen sits right on top of the supply crunch. Mizuho initiated coverage with an Outperform rating and a $405 price target, implying upside of more than 32% from current levels. The stock is up 23% for the year already, but Mizuho argues the rally is far from over.

The bull case rests on geography and infrastructure. Roughly 98% of Talen's generation sits inside PJM, the largest power grid operator in the U.S. and home to a fast-growing cluster of data centers across Northern Virginia, Ohio, and Illinois. PJM's capacity auction price has exploded from $29 per megawatt-day in 2024 and 2025 to a current cap of $330 per megawatt-day — a direct read on how tight power supply has become. Mizuho analyst Anthony Crowdell expects that dynamic to push Talen's adjusted free cash flow yield to 14% by 2028. Talen also controls the Susquehanna nuclear plant, a carbon-free baseload asset already tied to a deal supplying up to 1,920 megawatts to Amazon, and it recently closed the acquisition of Cornerstone, adding roughly 2.6 gigawatts of generation capacity across three PJM plants. Federal regulators are also pushing grid operators to speed up how large energy users like data centers get connected, a potential tailwind if the reforms go through. As of the most recent quarter, 87 hedge funds held Talen shares, up from 85 the prior quarter, with total holdings topping $5.5 billion.

For investors chasing the AI trade without buying another expensive chipmaker, Talen is a way to bet on the physical infrastructure AI actually runs on — power. That said, the risks are real: regulators already blocked one Talen power deal with an adjacent Amazon data center over grid-reliability concerns, and local opposition has killed at least one rezoning request for new data-center capacity in Pennsylvania. If hyperscaler capital spending on data centers ever slows meaningfully, Talen's growth story slows with it. Treat this as a higher-conviction, higher-volatility utility play rather than a defensive dividend holding, and size the position accordingly.
