Even if you do get it tied in any new changes require recertification. I can understand the position of the ILEC. The homeowner just wants to get up and running quickly. The electric company wants to ensure the stability of the grid.
It's not necessarily. If you use solar cells in your home, CO2 emission is something like 180g per kWh. In that case you'd be better of getting you power from the grid, if you can buy power from wind farms or nuclear power plant. It's better than coal, but only marginally better than natural gas.
If you happen to live in a country where you'll need heating for large parts of the year, it also pretty hard to beat the efficiency of a large district heating plant.
Sure making your apartment energy independent doesn't have to the romanticism, but it still has the engineering problem.
Ok, if I max out my stove completely it could _theoretically_ reach around 10 kW, but only if all four burners AND the oven are turned on at the same time.
It feels like it would be a better idea to install a battery in high-effect appliances to spread out the consumption over the day, than having a guaranteed 11 kW effect available 24/7/365 just in case... (and not everybody needs a stove with four burners, or even reliable power)
