High voltage DC transmission would connect places with large wind and solar resources to places with large electricity demand and allow the electric grid to be more resilient by being able to draw on available resources at more times. What is the biggest impediment to building new long distance transmission? a. Multiple jurisdictions that the lines would have to cross and NIMYB-ism of all the stakeholders whose territory or jurisdiction can block permitting of transmission. b. FERC. The Federal Energy Regulatory Commission just can't seem to get around to approving more transmission. c. The National Environmental Protection Act (NEPA) d. The Fundamental Law of Megaprojects. They are over budget, over schedule, over and over again! e. Expense. There's just no funding for a project like this that could never make money
