Here in Australia one other problem with the power system is privatization. What was a Utility is now a expensive shambles, here in South Australia it is the worst. The company that runs the infrastructure doesn't have enough line workers, & is getting rid of more. If theres major storm damage as in several weeks ago, a lot of customers were with out power for 2 weeks, & workers had to be imported from another state. Current political answer is get a backup generator. I used to work as a Linesman with the old system ETSA ( Electricity Trust South Australia). Back then there was enough workers to cover maintenance, & storm damage. Just last week during 43Deg heat here there was power shedding due to not enough power being available from interstate & thousands of customers were without power ( Heat wave with no wind at all) We are told theres plenty of Solar & Wind power but it doesn't seem to be working too well. I have had a 1.5Kw Grid tie solar system for 4 years now & last year was the worst output due to a lot of cloud cover particularly in summer. These are the annual total outputs of my system. 2013, 2742 Kw. 2014, 2365 Kw. 2015, 2603 Kw. 2016, 2075 Kw.
