Every second of every day, an invisible machine the size of a continent keeps supply and demand for electricity in perfect balance. Flip a switch and the power is simply there, yet the grid stores almost nothing. How does it keep the lights on?
Edward Callenford takes you inside the largest and most complex machine ever built: the electric power grid. He explains the delicate dance of generators spinning in unison, the reason frequency must hold at exactly sixty (or fifty) cycles a second, how power flows across thousands of miles of wire, and why a small fault can cascade into a blackout that darkens whole regions. He also confronts the great challenge of our age: weaving wind, solar, and batteries into a system that was never designed for them.
Lucid, gripping, and illustrated with original diagrams, this book turns the hum of the wires overhead into one of the great stories of modern engineering.
