Interesting EO on bulk-power systems.

I think one thing that may be targeted by this, is the monopoly big utilities refusing to interconnect with small power producers. Such as a homestead with micro-hydro
Or a small town with a small modular nuclear reactor (SMR)

And I believe this EO would also apply to the central control equipment that connects to all the smart meters which were installed because of the UN's Agenda 2030 to bypass Federal and State governments by targetting municipalities.
Of course, SMR is not the only type of power generation. There is also LENR, redox flow battery systems, fuel cell systems, and just plain local natural gas generators too. It becomes impossible for a foreign power to control the US power system when the small number of huge utilities lose control over the system. This EO could lead to open (as in public/non-secret) interconnect systems, policies, and processes. It would also lead to new technology because the process of switching from a broken power source to several alternative ones should be more automated and safe than it currently is. The current system risks cascading failures, but we have knowledge in the telecommunications networking industry on how to avoid those.
