The new interconnection rules allow limited export, and the largest users of this will likely be Growing operations in older buildings, with an existing 500KW or so service.
Many growing operations are looking at Diesels to provide the additional power to the building for lighting, etc.
In once case it is 40MW of diesel. (Real plan from a real company)
The new DER rules would allow that 40MW to be connected to the grid through the existing 500KW transformer and inadvertently export for about 30 seconds before curtailing. The MPSC says this complies with IEEE 1547-2018.
I would not want to be a neighboring business with sensitive electrical equipment.
Would you?
