The evidence strongly and consistently supports the existence of projections warning about a future shortfall in the U.S. power supply. Multiple highly credible sources point to the North American Electric Reliability Corporation (NERC) as the originator of these warnings. The NERC agenda explicitly mentions its Long-Term Reliability Assessment (LTRA), which is the type of report that contains such projections. This is corroborated by a Financial Times article that directly cites a warning from NERC about a potential "power crunch." Furthermore, a quote from the CEO of Exelon, a major utility, confirms that the "warning lights are on" and also attributes these warnings to NERC. PJM Interconnection, a major grid operator, is also shown to be actively engaged in analyzing future electricity demand. While the specific year 2028 is not explicitly confirmed in the provided summaries, the collective evidence from authoritative industry and media sources overwhelmingly affirms that credible projections warning of near-term power demand exceeding supply do exist. The statement's core claim is about the existence of such a projection, which the sources validate.
