in the Chickamauga area. It would be my guess that the power supplied by those lines was all supplied by other companies before the T. V. A. went there. I would like to find out what the facts are in this connection. Mr. BLANDFORD. That is not an easy request, you understand. Mr. BLANDFORD. We will have to revise that list and bring it up to date. Mr. WIGGLESWORTH. That is not what I want. I want the list brought up to date, but I want in addition a list indicating where the power came from before, the extent of available power, and the extent of the demand for power. In other words, if you have put a line into a given community, or are suggesting putting a line into a given community to furnish power for the year 1939 I would like to have all the available information you can supply concerning the facilities that are now available in that community and amount available, and the demand for power. Mr. LILIENTHAL. That question was asked before. Mr. WIGGLESWORTH. It was. Mr. LILIENTHAL. That is a difficult one to answer. We can give you a table showing the total power supplied in that area, of the capacity of the line to carry that power to these various communities but, we do not know how much power was supplied from any particular source. The difficulty is that except in one or two instances, none of these communities have power facilities specifically allocated to them, do not have power development of their own, but derive power from some pooling of power for an area. It would, therefore, be beyond our knowledge to allocate these area power facilities to any particular community at any one time. My point is that the information is not available to us, Mr. Wigglesworth, for the reason that we do not know, where, for instance, Nashville gets its power, at any particular time. They get it from several directions and all we could do would be to furnish a map of the facilities over which it may come. Mr. WIGGLESWORTH. In the tables you have given us on pages. 478 to 483 of the hearings last year you could show in every instance the general source of previous power, the demand for power in the county, and the amount of power available to that county. Mr. LILIENTHAL. Not the particular facilities. The power company supplied it from certain facilities through an interconnected. system. Mr. WIGGLESWORTH. I think you understand the information I am trying to get at. It will be appreciated if you will put in the most helpful statement that you can furnish in the form of a table or other method. Mr. BLANDFORD. We will be glad to do the best we can. Mr. BLANDFORD. The answer to the question of Mr. Wigglesworth follows: The precise information requested in answer to the question as formulated is not available. However, the purpose of the question is. apparently to determine the extent to which the transmission lines. of the Authority duplicate the existing power supply facilities of the private utilities in the area. This question can be answered briefly and explicitly. As a preliminary it is necessary to distinguish between the two senses in which the word "duplicate" is used. It is customary practice for utilities to provide "duplicate" facilities to insure dependability of service and practically every important load center is or should be supplied either with spare generating capacity or with one or more spare transmission lines as an insurance of satisfactory service. Such facilities are "duplicate" in the sense that they are double but they are not "duplicate" in an economic sense. In the latter sense what is meant is power supply facilities not needed for adequate and dependable service. We assume that your question went to the existence of duplicate facilities in the latter sense and have accordingly limited our answer. It may be stated categorically that virtually all of the power supply facilities of the Authority, both generation and transmission, are valuable and necessary additions to the power supply facilities in the area. At the present rate of growth of the load all of the power which the Authority can generate will be required to supply the growth of demand in the next few years, unless, of course, the utilities should elect to provide new facilities of their own to meet all load growth. Similarly, if it be assumed that the Authority's transmission lines present and proposed will be interconnected with those of the major utilities in the area in the same manner as the Authority's existing interconnections with the Commonwealth & Southern system at Wilson Dam, Ala., and Columbia, Tenn., and with the Electric Bond & Share system at Memphis, in order to secure the most efficient use from the power supply facilities of the area whether publicly or privately owned, all of these transmission lines would be valuable and necessary additions for adequate and dependable service. The line under construction from Columbia to Murfreesboro is a minor exception. This is a line of limited capacity, necessary for service to the Authority's existing rural cooperative customers. This line would not be presently necessary if there were an interchange arrangement with the existing utility operating in Murfreesboro. The Columbia-Murfreesboro line would not be without value even if such an arrangement were consummated, for it is, in any event, a worthwhile means of supplementing and strengthening the existing network in the area. A further qualification should be stated as to certain substation facilities. Where a municipality elects to distribute power to its citizens in competition with an existing company, to the extent of any net loss in load by the existing utility there will be duplicate substation capacity. However, substation equipment has a very high salvage value and it is in fact common practice among utilities to shift transformers and other substation equipment from place to place as changes in load warrant. PURCHASERS OF T. V. A. POWER Mr. WIGGLESWORTH. Would you also give a list showing all those who now purchase power from the T. V. A., with a break-down by municipalities, cooperatives, and other purchasers, showing the amounts supplied in each case and the rates charged. Mr. BLANDFORD. That will be supplied.
