The U.S. power grid has delivered electricity reliably for decades. However, today the grid faces challenges that are driving transformation, reshaping its operational scope and the technologies on which it relies.

Inspecting and monitoring long-distance transmission lines has always been both costly and dangerous for utilities. Networks that stretch across remote, rugged terrain make traditional methods like climbing towers, deploying helicopters, or sending out ground crews resource-intensive and risky for workers. Today, autonomous drones are changing this process by offering a faster, safer, and more cost-effective […]

In the past decade, we have seen “once in a century storms” almost every year, flash floods wiping out entire towns, and extreme heat that melts shoes on pavement. Our climate is becoming more extreme, and we need to be proactive in preparing our infrastructure for more to come. The annual average for U.S. billion-dollar […]

Regulators in North Dakota have given their approval for a 1,490-MW natural gas-fired power plant, a combined-cycle station that Basin Electric Power Cooperative officials said would provide the area with its first new baseload electric output in more than four decades.
