The NESO App 4+

I use this App to judge the best time to use electricity and also charge my Hybrid car for minimum environmental impact.
Since the latest App update they have made it incredibly difficult to discern which source of Electricity is from what source as the colours chosen are completely illogical. Light purple for Gas, Dark purple for Wind!? So is wind more polluting that Gas? That’s what the colours say to me! Imports are Blue, water isn’t!? Solar is dark blue? Why not yellow or orange? Make the colours represent either reality or their Eco impact. Black for Biomass, Brown for Gas, blue for water, green for wind, yellow for solar, Orange or Purple for imports etc. I shouldn’t have to decode the App before I use it to decide if it is a good time to use green electricity. Help us help you!
What I would really like to see is the daily/weekly/monthly running totals for each kind of electricity production technique with a running total for the CO2 produced to generate the electricity.
I want to be able to see and compare how much each individual type (wind/solar/water/nuclear/gas etc) has produced and what CO2 it has cost us. Ideally by country area but defo in total per country. Live data on this would be excellent as well. A display of total electricity demand Vs system provided would be an interesting readout.

It's confusing that this app recommends different times to the other National Grid app. It's odd that different parts of the same organisation have both made apps, but you'd expect them to agree on the numbers! Ideally there'd be one app, with the clear display that this app provides,and the alerts available in the outer one.

The national view is good and seems accurate comparing to other sources. An overall carbon intensity figure on the home page would be better than the meaningless A-F scale which almost reads “C” on all but the calmest nights/windiest days. It is a little fiddly to open and close the panel with the 12 hr future predictions, on an iPhone 8 there’s little margin to click in to close them. As that’s the unique feature of the app and the one that would most help people actually reduce their carbon footprint it’s a shame it’s not more easily accessible.

The data in the regional info often makes no sense. Right now it’s saying Southern England has a Carbon intensity of 26, and that 99% of its power is coming from gas. Clearly both can’t be true at the same time!
