Im beginning to think you dont believe in advancement/evolution. Take a look around you, old ways/ideas/products are getting replaced by better, brighter and newer things EVERYDAY.
You bring up a good point about the old way of doing things... They PAY for cap banks and are VERY expensive... its a good thing PAS is free to install for the Utility/Customer. Free to install/manage AND get kick back revenue from savings in less blackouts/maintenance/govt sanctions/fines... Free and $$? No brainer. Brutal working 7 days a week, dont even get weekends off?
