Some energy companies I know have their own rooms full of analysts looking into things like what's on TV tonight so they can forecast demand spikes e.g. in the breaks of sports events. They also have data science teams to place their wind farms optimally in-house (my knowledge of the sector is geographically limited to Europe and the midwest of the US).
So make sure that whatever you are getting into is a true need that more than one potential customer actually has, rather than basing things on assumptions alone (customer validation of the proposition).
I worked for/with one of those teams at ESB - Ireland's national electricity provider. We built a cutting edge real-time visualisation of energy production/usage from all the power plants in the country using different fuel types and forecasting models like yours in order to get the most out of renewables and also give the traders an edge.
I was thinking of doing my own system too so love what you guys have done. I'm currently just working on my own side projects so open to opportunities if you guys might have some? :)
