Do you remember the hurricane of "historic proportions?" You most likely slept through it. Let me give you some key points to think about. Baltimore Gas and Electric cut back 1,500 personnel designed to address these types of disasters. It was more economically feasible to retain the service of others outside the utility such as members of other utilities or private sector people to call in to restore power. You can also throw the burden of this expense onto BGE customers, so the net result is it's free to BGE.
Here is one more tidbit to consider. In order to prevent tree limbs and such taking out power lines, BGE had in place a very effective line maintenance program where crews would go out and trim back encroaching tree limbs — just as other utilities do. This program wasn't eliminated but was scaled back drastically.
