A once-in-a-decade heat dome baked the eastern United States this Fourth of July weekend. PJM Interconnection, which serves 67 million people across 13 states, believes that Friday’s demand passed a previous record set all the way back in August 2006.

Dan Leonard, Director of Forecasting for the USA at MetDesk, joined CNBC on July 1st to talk about the implications of heat waves.

The investment angle sits with the power grid. “What you want to look at here is the electricity power plays, because there’s pools like PJM, which are forecasting record load. I think the previous record in PJM is like 161 gigs. We’re forecasting 166 on Friday, which would beat the old record by five gigs,” Leonard said. He added: “We haven’t seen heat like this since 2012, so we got to go back a ways when basically the entire eastern half of the country was impacted.”

Structural pressure is compounding the weather. “We’ve added a lot of wind and solar over the years, but we’ve also added a lot more load with these new farms coming in and with population increase and data centers,” Leonard noted. Data center electricity use has already jumped from 1.9% of total annual U.S. electricity consumption in 2018 to 4.4% in 2023, with Lawrence Berkeley National Laboratory projecting up to 12% by 2028. When PJM wholesale prices spike, merchant generators with dispatchable capacity capture the upside.

Vistra

Vistra Corp. (NYSE:VST) is the largest independent power producer in PJM with 13.9 GW of capacity including nuclear, and its pending Cogentrix acquisition adds another 3.2 GW. Q1 revenue hit $5.64B, up 9.1% YoY, per the company’s SEC filing. CEO Jim Burke said “Load growth remains strong across our primary markets.” Shares trade at $154.81 against an analyst target of $222.89.

Constellation Energy

Constellation Energy (NASDAQ:CEG) is the second-largest PJM capacity owner with 20.3 GW and runs the biggest nuclear fleet in the US. The stock jumped 11% after the last PJM capacity auction, and Constellation is now the largest US wholesale power provider after buying Calpine. Q1 revenue hit $11.12B, up 63.9% YoY, with adjusted EPS of $2.74. Shares closed at $240.41, down 29.49% year-to-date, against a consensus target of $360.24.

Talen Energy

Talen Energy (NASDAQ:TLN) is concentrated in PJM with 13.1 GW and just closed a $3.5 billion deal in June 2026 to add 2.6 GW of gas plants. It also has demonstrated dedicated power arrangements for data center campuses in Pennsylvania, including an expanded 1,920 MW Amazon PPA at Susquehanna. Q1 adjusted EBITDA reached $473 million. Shares last traded at $373.99, versus an analyst target of $473.22, with 15 buy or strong-buy ratings.

NRG Energy

NRG Energy (NYSE:NRG) runs a merchant power model with gas-fired projects in PJM and recently acquired LS Power’s gas fleet to expand its footprint. That deal added 13 GW and doubled NRG’s generation base. 2026 guidance calls for adjusted EBITDA of $5.33B to $5.83B. NRG shares trade at $142.81, up 6.1% over the past week as heat forecasts intensified, against a consensus target of $198.88.

What Investors Should Watch

Merchant power stocks live and die by weather and wholesale prices, and all four names above have already been volatile in 2026, with Constellation off nearly 30% year-to-date even as Talen holds a modest gain. A record-breaking PJM print on Friday could reset near-term sentiment, but the same volatility that creates upside during heat events cuts the other way when demand cools. Investors evaluating this group should track the PJM real-time load data, capacity auction outcomes, and follow-on data center PPAs, rather than treating any single heat wave as a durable catalyst.
