Niagara polyphase current is transmitted commercially to Buffalo
In mid-November 1896 Niagara’s polyphase plant began sending commercial current to Buffalo, New York. In the causal graph this event strengthens Energy-Price Volatility, a driver that strengthens Difficulty making ends meet — a worsening welfare path.
Read the full account
In mid-November 1896 Niagara’s polyphase plant began sending commercial current to Buffalo, New York. It is a dated transmission opening, not a continental interconnection.
Context
DC’s short radius was the rival limit stored on Edison’s dossier. Rate series for Buffalo households are not supplied here because they are not in the cited milestone pages as a complete tariff table.
Nikola Tesla is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
High confidence on 1896 Buffalo service; medium on a dollar series.
A twenty-mile line is not rural electrification statute. Keep the lag.
Who was responsible

Complex: utility, Westinghouse transmission engineering, and Tesla patents. Direct sole transmission is the wrong type.

What the sources establish
IEEE/ETHW’s Niagara milestone frames long-distance AC from Adams. Smithsonian’s current-war account independently treats Niagara-to-city transmission as AC’s industrial proof.
Established: commercial Niagara-to-Buffalo AC transmission in November 1896. Not established: a 49-state grid, or that Tesla threw the Buffalo switch as a utility officer.
