Outdated transformers along our mini grid

Our residential power was out for 68 hours (4/6 at 10:30 pm to 4/9 at 6:30 pm) with almost no notification of status, despite multiple requests to Excel customer service. One transformer along our grid was replaced on 4/11; however, the whole gird system requires updating.

In addition, a resident in our neighborhood is reported to be drawing inordinately on the system due to a crypto currency operation. Should that draw be moderated or eliminated by some standard of use for a residential neighborhood?

Thank you, Karin Perry, 3010 Wright Street, Wheat Ridge CO 80215
