These ‘grid enhancing technologies’ look like cheap fixes that can only buy some time before real work is needed. Sure, with better monitoring and some overload management systems you may work closer to some limits, but that’s not a solution for long-term usage increases.

Where I work, they are used a lot to adjust for renewables power surges, not to increase transit.

The bit about automaticaly shifting power to other lines in a strained network is interesting, but I wonder how much security analysis is run to make sure it’s safe (or if it’s just an automation system working within bounds the operator deemed safe).

> When the wind blows, for example, power lines are cooler, allowing for more capacity. Okay, but what do you do when the wind isn't blowing? How do you get people to only charge their cars when it's windy?

Solar anti correlates with wind. Then the typical:

- Large grid to decouple weather patterns

- Demand response

- Storage

People already get on hourly contracts and schedule car charging for when it is cheap. The next step is automating it and making it more streamlined.

Some companies already support chargers which integrate with the pricing, they can even give you money back through demand response.

Another big thing is streamlining regional abilities to accelerate permitting for replacing old transmission line conductors.

Modern conductors can transmit significantly more energy by better conductor design, so replacing ancient conductors is a relatively cheap way to increase transmission capacity while also reducing line sag which makes the transmission lines safer.

Market prices and "smart" chargers

You don’t, but you can schedule work on nearby lines at this time for instance.
