2011–2044 was expected to be $20 billion in gross state product, or about $330 million per year in disposable income and $20 million per year in state tax revenues, also assuming all three units continued running. Regional effects of installing SCR and baghouses would include increasing CAP water rates by as much as 32% for agricultural users and Indian tribes. If the plant were to shut down, those rates were expected to increase as much as 66%. In 2012, NGS and the Navajo Tribal Utility Authority (NTUA) formed a partnership to extend electrical power to 62 homes in the area surrounding the nearby community of LeChee. Since NGS participants have no jurisdiction for supplying electricity on the reservation (that authority belonging solely to the NTUA), NGS and the NTUA would jointly fund the project, and the NTUA would build it. Water service contract Water used by the plant is supplied from Arizona's annual allocation of 50,000 acre-feet of upper basin Colorado River water through Water Service Contract No. 14-06-400-5003 with the U.S. Bureau of Reclamation and Arizona Department of Water Resources permit A-3224. Water payment rate had been $7 an acre-foot, resulting in payments to the U.S. of about $180,000 per year.Payments were set to increase to $90 an acre-foot in 2014, or about $2.4 million per year. By comparison, water rates and leases in the Four Corners region are typically $40 to $155 per acre-foot. Production Navajo Generating Station's production is as follows.
