The power business has always rewarded patience. Big plants take years. Transmission takes even longer. Regulators move on their own clock. For decades, utility leadership could be judged by whether the plan made sense over ten or twenty years. That is still part of the job, but it is no longer enough. A clearer leadership test has emerged in the U.S. power sector: who can deliver real power to real load faster than everyone else. Regulators are acting on it. Grid operators warn that demand is arriving faster than the system can comfortably absorb. And the heat wave now bearing down on the eastern half of the country is showing what happens when growth, congestion, and thin margins converge.
