You are right Barry, The decision was in favor and there are no other equipment yet defined in Class D. I have send the list a press release from cenelec a few days ago about this subject. However, this was a compromise between industry fighting against and power companies on the other side. It was said by people witnessing the disc(p)utes that it was the toughest discussion since standardization started.
With the next revision this compromise will certainly extend into the direction of other equipment within the power limits fall in Class D as long as it meets the criteria formulated as: "having a substantial influence on the power system".
