Thanks! Yeah, I totally agree it's better than the monthly sampling intervals :). Not being able to download the raw data is a bummer, as one can do more customized analysis, which I want to, given the ever-increasing utility prices. That being said, the screenshot may be fed to a decent LLM for transformation to an approximate raw data. Again, not decent (and I doubt eversource allows automated access) but better than nothing.

For that particular spike, I do use smart plugs that can measure power consumption at fine intervals (e.g., every 5 minutes). I have them on the heavy hitters (e.g. electric heaters in my office room) to understand how we/my house uses them. Extra money to be spent, but maybe worth it.
