HN: I'm looking for an item highlighting an app for utility/power companies

Tried searching for it, but I can't find the proper combination of words to produce a query good enough to locate this thing.

Essentially, it was something that could be used by utility companies to provide customers with a highly interactive and attractive portal to pay bills, visualize their energy usage, compare their kw/h with that of their neighbors, suggest energy saving tips (such as turn your thermostat down two degrees today), and the like.

Can anyone point me in the direction of this thing? There's someone in my senior staff I think this will really impress.
