Electric substations: In 1889, the City of Paris granted an 18-year concession to six companies charged with installing and operating power grids. At the time, all power stations used coal and emission levels were very high. Some were inside Paris proper (rue des Dames, quai de Jemmappes) and others were on the outskirts (Ivry, Levallois) but the high-voltage current generated was carried to substations where it was transformed into low-voltage current. It was also transformed into continuous current for trams and the metro, since motors using alternating current came later and continuous current also has some advantages. In 1898, Compagnie parisienne du métropolitain, the metro operator of the time, built its own power station behind its headquarters at quai de Bercy. Over 20 power stations and substations were designed by architect Paul Friésé.
