On February 5, 1898, a group of New Yorkers purchased the local gas and electric company for $199,000. This was the beginning of the Utica Gas and Electric Company, which closed the local gas plant and piped in gas manufactured in Utica. In 1931 a 500,000 cubic feet gas storage tank was built on Loomis Island which was dismantled this January. In 1951 natural gas replaced the manufactured gas.
