I'm very glad that she got back to me, but I have to say that I am disappointed in NSTAR. Let me say from the outset that I could very well have my facts wrong, but from what I understand, NSTAR hasn't done the upgrade they've really needed to do on our transmission lines over the past few years. Basically, it's a large capital expenditure to upgrade everything, so instead of fixing it all at once they've simply patched it as problems arose. Needless to say, this results in a system that in the long run, costs more money to fix.
It reminds me of an experience I had once at a school where I was teaching science with old textbooks. I wanted to buy a brand new set of books, but I couldn't because we didn't have the budget for it. Every year, however, I'd have to replace a bunch of the old books because students lost them, and so I had to buy replacement books that I knew were out-of-date. So instead of spending a whole lot of money at once to get new books, I spent that same amount of money over a few years replacing out-of-date books.
If anyone from NSTAR is out there reading this and can correct my understanding of the situation, I'd be happy to hear from you.
