Taking the latest in computing and communications technology to make the electrical system more interactive, efficient, and robust is not a new idea. What’s new is that suddenly more than 10 billion federal dollars are being poured into it. But all that money will be well spent only if regulators are as inventive and intelligent as transmission and distribution engineers have been.
