The other thing to consider would be sharing of load with the grid. If the installation is using more power than the Bluegen can provide, the extra load is taken from the grid.
Once the grid is lost , load shedding would be required to a level not greater that the Bluegens output rating.
In a nutshell, correct phase sequencing and load shedding would require extra cost and maintenance to the installation , and not in the initial interest of promoting a new technology like the BlueGen at this stage
