It is not correct to attach "qualifers" to an SI symbol. However, I am about 95% sure that is what they are doing, Wt for watt-thermal, We for Watt-electrical. Steam plants are about 33% efficiency, more or less, in converting heat to electricity. Such distinctions are very common in electrical generation. Often, they are subscripts. Still wrong, but common.
