On November 31, 1905, a New York Times headline read, “The Mayor Starts New City Light Plant – The New Bridge All Aglow” after Mayor McClellan pulled down a copper switch to illuminate the 2793 foot span with electricity made by burning the City’s garbage. (In truth, the bridge was not fully illuminated until January 1906.)
The Engineering Record, from November 11, 1905, stated “The first attempt on a large scale in this country to utilize the electricity made available by burning rubbish has begun.” It was hoped that the $90,000 plant would not only pay for itself but would also save the city $12,000 per year in annual lighting costs. While initial reports claimed that the experiment was a success, it would be short lived.
The first hint that something was amiss was the absence of information about the experimental plan in the Department of Bridges reports. The only notation came in a single line in the 1906 Annual Report about the use of the land under the bridge: “the greater portion of the land between East and Tompkins Streets has been given over to the use of the Street Cleaning Department, for a rubbish incinerator, and to the construction of an electric light plant for the bridge.” In addition, the 1906 Street Cleaning report did not mention the project, although they had dedicated nearly 30 pages to the experiment the previous year.
Answers came in a letter to the Mayor from the Street Cleaning Commissioner Macdonough Craven, dated January 23, 1907. Craven spelled out the problems of the project. It seems that when devising his plan, Henry De Berkeley Parsons had not accounted for the difference in electrical usage during the long spring and summer days, versus the darker winter and fall period. The Street Cleaning department discovered it needed to burn more than 1,100 tons of coal to compensate, which appeared to have been an unexpected cost. After one year of operation, the department experienced a net loss of $19,621.
