This would also be in line with the national <br />and NSP's commitment to energy conservation. In response to <br />these objectives, NSP has developed a new program to reduce <br />the number of energy inefficient street lights on its system. <br />The options under this program are as follows: <br />1. At your request, NSP will convert any NSP owned <br />overhead incandescent or fluorescent street light <br />to new energy efficient high pressure sodium at <br />no charge for the conversion. The monthly billing <br />for energy and maintenance will be changed to the <br />high pressure sodium rate which will usually result <br />in lower cost to your city if present light levels <br />are maintained. <br />2. At your request, NSP will convert any NSP owned <br />overhead mercury street light to a new energy <br />efficient high pressure sodium unit. The one time <br />conversion charge to convert a mercury unit to high <br />pressure sodium is $5.00 per unit. The monthly <br />billing for energy and maintenance will be changed <br />to the high pressure sodium rate which will result <br />in a slightly higher cost tooytpur city but will also <br />slightly raise the light lev&1 in your city. <br />27 <br />
