My understanding is that the high voltage transmissions have little resistance, and that the biggest problems with a national grid is not transmission loses but the cost of building thousands and thousands of miles of high voltage electrical wiring to connect existing subgrids together.
Do I have a misconception?
- Retric 8y agoAdding wiring is fairly cheap per mile, connecting different electric networks via substations is the more expensive bit. The larger issue is capacity needs to be used regularly to be cost effective. If you want to send 10GW for 24 hour a day or 15 minutes they both need the same infrastructure.
