I am busy with a project (cant talk too much about it...due t privacy consent etc ) what i can tell you is people sure know how to milk the tax and rate payer.

Do the maths ...if you have a 3000 amp power supply from a transformer... the estimate done by the electrical consulting firm ...then they add in 2000 amps of solar power... at peak... but the max load consumed by all your tenants is 350 amps during peaks hours... what would the return on invest be? ... Then offer a solution... the solution is to upgrade the power to the tenants who dont require the additional power but you can make another R10 mil in revenue installing an upgraded system... just because nobody is auditing your services.
