It's a sign of the eventual retirement of the Ginna Nuclear Power Plant.
The operation involves some rather old-fashioned transportation.
Two huge transformers that will someday allow RG and E to wean itself from nuclear power were built in China.
The 236-ton machines came to the US by freighter, then by Erie Canal barge to Macedon.
This week, they'll get to a substation in Perinton on two huge 12-axle self-propolled flatbeds.
The transformers will help RG and E use more hydropower from Niagara Falls, and are part of a 140-million dollar project to boost the capacity of the local power grid by 2017.
