Existing Mercury Vapor Lighting: <br />Sodium Vapor Replacement: <br />Wattage Lumens kWh <br />Wattage <br />Lumens <br />kWh <br />175 7,900 70 <br />100 <br />9,500 <br />40 <br />400 21,000 150 <br />200 <br />22,000 <br />80 <br />or 100* <br />9,500 <br />40 <br />or 150* <br />16,000 <br />70 <br />or 250* <br />27,500 <br />100 <br />1,000 63,000 370 <br />400 <br />50,000 <br />160 <br />Or 1,000 * <br />140,000 <br />375 <br />* - Available as a replacement upon customer request. <br />The replacement of mercury vapor ballasts and fixtures to sodium vapor will be done at no cost. <br />Oncor would note that if a street lighting customer desires to replace the mercury vapor fixture or <br />ballast with a metal halide fixture or ballast, the customer may do so by paying the additional <br />cost, consistent with the "Conversion or Replacement of Existing Facilities" portion of the Street <br />Lighting Tariff.1 <br />Replacement by Oncor of burned -out mercury vapor bulbs in service under its outdoor <br />light service will continue, as bulbs — as compared to ballasts and fixtures — are not restricted <br />under EPACT 2005 and will remain available. However, on or after March 1, 2008, when <br />mercury vapor fixtures or ballasts must be replaced, the fixtures or ballasts will be replaced with <br />high pressure sodium equipment as set out in the conversion chart (or metal halide if requested <br />by a street lighting customer and upon payment of any additional costs), or customers may elect <br />to cancel service at no cost. <br />II. REQUEST FOR APPROVAL <br />With respect to this Petition, Oncor would note that: (1) it would not change the revenues <br />received by Oncor for an existing service; (2) it would not allow Oncor to begin charging for a <br />service previously available but for which there was not a separate charge; (3) it would not <br />immediately eliminate an existing service to which one or more customers actually subscribe, <br />and would provide alternative fixtures when mercury vapor ballasts and /or fixtures need to be <br />replaced; and (4) it would not increase a customer's bill even though the rate for a particular <br />service is not being changed, because as shown by a comparison of mercury vapor kWh <br />consumption and lumens with the high pressure sodium consumption and lumens, the <br />replacement fixtures produce more lumens per kWh and are therefore more energy efficient. <br />This option is not available for Outdoor Lighting Service customers. <br />2 <br />
