IMHO, the biggest obstacle over here (NJ) is for the POCOs to obtain any/all of the approvals to do any upgrades. There is a transmission project (upgrade to 400+KV) thru the northern sections of the state. The approvals are 'almost'; after at least five years. I believe is is less than 100 miles, mostly along existing ROW, with 'taller' towers & monopoles.
With gen plants; nothing new is being talked about. We are loosing one nuke (Oyster Creek/Excelon) in <10 years with nothing new on the table.
Solar? PSE&G has 220k individual panels on utility poles throught their teratory, and solar 'farms' up & running, with more in the pipe. (5MW+) Wind? a few along the coast outside Atlantic City, talk about off shore wind farm, but a lot of NIMBY flak.
The PJM grid has held on so far this year; only time will tell.
