Yes, Con Ed now has smart meters that report electricity usage in realtime at 15 minute intervals. If you use Home Assistant, you can perhaps make use of the Opower integration to get this data: https://www.home-assistant.io/integrations/opower/
Although implementing the realtime API in the Opower integration has not yet been completed. That said, I don't think it would be too hard to implement. See: https://github.com/tronikos/opower/issues/24
This realtime data is also available and graphed on your account page on the Con Ed website and mobile app.
I wrote my own code that uses Con Ed's realtime API and writes the data to Prometheus so that I can view it in Grafana. My code was heavily influenced by Home Assistant's Opower integration code. Here's my code: https://github.com/dasl-/pitools/blob/main/sensors/measure_e...
