The pullback highlights how fast traders are revaluing merchant power stocks linked to data centers and wholesale markets. This sector has turned into a hotbed of political and regulatory tension, with grid operators flagging reliability concerns and consumers pushing back against soaring electricity bills.
Federal regulators have stepped in on co-located load arrangements in PJM Interconnection, targeting data centers that team up with nearby generators.

Investors are focused on PJM’s ongoing co-location dispute and whether special-auction proposals targeting data-center demand gain momentum. All eyes turn to Feb. 16, the deadline for PJM’s initial briefs at FERC.
