Icon request: energy grid icons

Hello,
I am missing multiple icons for the energy grid, for example export into the grid, import from the grid, disconnection from the grid/self-sufficiency, the grid being offline, etc.
Also missing is some icon symbolizing a house in connection with energy. could be just like the e-bike or ev symbol, the original symbol with a bolt beneath.

We used these before:
https://pictogrammers.com/library/mdi/icon/transmission-tower-export/
https://pictogrammers.com/library/mdi/icon/transmission-tower-import/
https://pictogrammers.com/library/mdi/icon/transmission-tower-off/
https://pictogrammers.com/library/mdi/icon/transmission-tower/
https://pictogrammers.com/library/mdi/icon/home-lightning-bolt-outline/

I think they are very fitting for most use cases around this topic. I think variations of the arrow could be thinkable, like putting the arrow on the lower right as an "overlay" like many other icon-variations do, and then maybe angling the arrow by 45 degree.

I could also think of instead of using the transmission tower symbolic, one could just display an actual grid (maybe with a power plug at the end of one line to make it more obvious?) and then add the arrow.

Start by reviewing the linked transmission-tower and home-lightning-bolt icons as references for the proposed energy-grid symbols. Clarify which icons and arrow treatments are required, then check the project’s contribution guidance for icon design and review expectations. Done means an agreed, complete set of energy-grid icons is contributed and accepted.
