In Japan about 16 million units of distribution transformers are in service. These transformers are expending a huge amount of energy in the form of no load loss and load loss. Among these losses, no load loss is major. No load loss can be saved dramatically by changing these transformers to amorphous transformers (i.e., amorphous metal-based transformers). This paper estimates the scope of the possible energy saving and reduction of CO2 emissions by the adoption of amorphous transformers in Japan and in China.

The lower bound of generation is NOT zero, as implied by the graph, but is actually negative when the windmill is not generating. The core is excited from the HV side, just like in a distribution system. When there is no generation, the transformer actually pulls power from the grid. For renewables, you should be using transformers with amorphous metal cores which cut no load losses by 70 percent.
