<br /> <br /> <br />Task 2.1.3 - Electrical Demands <br />A series of new conversion type energy technolog ies could emerge. In western Colorado in - <br />situ oil shale extraction is an example of this type of unconventional resource development. <br />The key in all conversion technologies (coal liquefaction, in - situ oil shale extraction, oil sand <br />mining, and coal gasif ication) is to produce electricity (coal liquefaction, coal gasification) or <br />have available electrical capacity for conversion (oil shale and oil sand). The current process <br />under consideration by the oil shale industry is to heat the ground in - situ with e lectrical <br />heaters to 700 degrees Fahrenheit to extract the oil shale. A survey will be carried out with <br />representatives of companies with oil shale research permits (Shell, Chevron, EGL) to gain <br />an understanding of the estimated amount of energy required per barrel of oil. Such <br />assumptions as, 250 to 300 kilowatt - hours for down - hole heating per barrel of extracted <br />product are required for development. From such assumptions one can begin to develop <br />scenarios for a n operation producing 100,000 barrels per d ay which would require <br />approximately 1.2 gigawatts of dedicated electric generating capacity. <br />Further assumptions on electrical demand for compressor stations and other natural gas <br />process will also be considered and mixed into the assumptions. We will a lso include the <br />increase in population that will require additional electricity for residential, goods and <br />services. <br />These assumptions will help us project demand for water to run electrical systems The <br />USGS estimates that for every 1 kWh of power there are 25 gallons of water consumed. The <br />increase in demand locally may be supplied from existing regional sources however <br />transmission systems also create restraint. Therefore we will survey local electrical providers <br />to determine constraints and opportuni ties. We will meet with the Colorado Public Utilities <br />Commission staff to identify any on going planning efforts to meet this new electrical <br />demand. <br />Task 2.1.3 Deliverable - Table outlining the various types of energy technologies and <br />ele ctrical demands for each energy conversion and supporting process es . This table will <br />include the electrical demands of the various development scenarios for various operations <br />producing 100,000 barrels per day (demanding approximately 1.2 gigawatts of dedicated <br />electric generating capacity. A summary of the electrical providers gathered during the <br />survey will also be provided. <br />Task 2.2 – Analysis of Water Demand <br />The scenarios evaluated in Task 2.1 will provide the water estimates for each of the three <br />categories as combin ed into near - and long - term and low and high development yield <br />projections for water demand. This analysis will also include a GIS spatial analysis of <br />where the water demand will be located. <br />Once the location of the demands is identified, URS will inp ut these demands into the White <br />and Colorado Decision Support System (DSS) models.
