US power grid upgrades get clearer rules for planning and cost sharing

US energy regulators clarified rules for how new regional power lines get planned and paid for. This means companies building these lines now have a clearer process for sharing costs across different regions.

Building new power lines in the US has been slow and expensive, often because of arguments over who pays for them. This rule makes the process for planning and sharing costs for these lines more predictable. It aims to speed up the construction of a more robust national grid, especially for connecting new power sources.
