.1.000, the overwhelming bulk of the power that is needed. Their argument is that Arizona has heavy power demands during the summer for air-conditioning and irrigation pump- ing; Utah has heavy demands for the winter period. Therefore Arizona can furnish peak I power to Utah in the winter and Utah can furnish peak power to Arizona in the sum- mer. In that manner the capital investment of both companies is materially reduced. In addition to that, the private com- panies say that the Arizona Public Service Company will construct shortly, and have in operation by 1962, a major thermal plant in the Four Corners country, and that from this thermal plant they will construct three 345 KV lines into Phoenix, Arizona. You have to bear in mind that the heavy power user in these five states is the State of Arizona. "The private power companies say 'We are going to build these lines anyway; why not utilize our lines? We can, as project power comes on, increase our 230 lines by multiple units. The cost will be much less to the Government and much less than the total com- bined costs'. Now under the system proposed by the private power companies, they say that the combined cost to the Bureau and to them would be in the neighborhood of $122,000,000 as compared to the $157,000,000 proposed by the Bureau of Reclamation, affecting a very substantial saving of something under $27,000,000. Under the private system all of the transmission in the States of Arizona, Utah, Wyoming and New Mexico would be taken care of by the private companies. Only Colorado would be served by lines to be constructed by the Bureau of Reclamation. Under their plan the Bureau of Reclamation would con- struct multiple 230 KV lines to the Four I Corners country and multiple 230 KV lines into Curecanti and also 230 KV lines into Poncha Junction. Remember the original Bureau plan proposed going into Pueblo with a 345 KV line. The private companies point out that they already have transmission facil- ities from Poncha Junction into Pueblo and then into Denver, and they are willing to construct another 230 KV line from Poncha Junction.
