In recent years, the energy-water nexus literature has recognized that the\nelectricity and water infrastructure that enable the production, distribution,\nand consumption of these two commodities is fundamentally intertwined. Electric\npower is used to produce, treat, distribute, and recycle water while water is\nused to generate and consume electricity. In the meantime, significant\nattention has been given to renewable energy integration within the context of\nglobal climate change. While these two issues may seem unrelated, their\nresolution is potentially synergistic in that renewable energy technologies not\nonly present low CO2 emissions but also low water-intensities. Furthermore,\nbecause water is readily stored, it has the potential to act as a flexible\nenergy resource on both the supply and the demand-side of the electricity grid.\nDespite these synergies, the renewable energy integration and energy-water\nnexus literature have yet to methodologically converge to systematically\naddress potential synergies. This paper advances an enterprise control\nmethodology as a means of assessing the techno-economic performance of the\nenergy water nexus. The enterprise control methodology has been developed in\nrecent years to advance the methodological state of the art of renewable energy\nintegration studies and used recently to carry out a full-scale study for the\nIndependent System Operator (ISO) New England system. The methodology\nquantifies day-ahead and real-time energy market production costs, dispatched\nenergy mixes, required operating reserves, levels of curtailment, and grid\nimbalances. This energy-water nexus methodological extension now includes\nflexible water-energy resources within the grid's energy resource portfolio and\nquantifies the amounts of water withdrawn and consumed. The simulation\nmethodology is demonstrated on a modified version of the RTS-96 (RTS-GMLC) test\ncase.\n
