The modern power plant contains many of the same components its had for decades: boilers, gensets, cooling towers, pumps, etc. But the sensors and software which keep watch are expanding in scope, intricacy and data volume. Interconnectedness and communication systems vastly improve efficiencies, but also widen the vulnerabilities to outside intruders such as hackers. And advancing at the edges are new technologies in artificial intelligence and beyond. The brave new world offers rewards and risks.
