I am also having this problem, only in my most recent save which is strange. I only have 1 green neighborhood so I dont think its an issue of compounding green neighborhoods. Any help with fixing it would be great or at least some acknowledgement of the issue by EA. I am happy to provide save file, just let me know if it is necessary. Thanks.
UPDATE: My game seems to have fixed the issue, although it was a strange process. Same lot and family and eco foot print, BUT I made 10 different "save as" games of the original to work on building them a new house. Please dont ask why I made 10 different ones, I couldn't decide what to build. But anyway on the 10th game the lighting blow out was gone, nothing had changed other than it being a new "save as" game, number 10 to be precise and Im happy its gone. I just wish I knew what changed to fix it more consistently. I have a pic but its too large to post so yeah, sorry about that.
