Talen Energy is considering alternative arrangements to supply electricity to data centers, executives with the major U.S. power company said on May 8, after regulators pushed back on a plan to fuel an Amazon data center directly from Talen's Pennsylvania nuclear power plant.

Independent U.S. power producers like Talen have seen a surge in interest over the last year -- propelling shares of the companies to record highs -- largely on the prospect of striking deals to supply electricity to Big Tech's data centers directly from the companies' nuclear plants. Regulator push-back on the so-called co-located arrangements, however, are leading some of those companies to make alternate plans.
