One of the circulars we have received from Tangedco quotes below
"Every year, 150 Nos. services are given totally to Widows, Physically Challenged, Ex.servicemen, Scheduled Tribes and Intercaste Married people
under special priority scheme. The above target has been increased to 250 vide Government letter dt. 18.6.2010 by including Serving Defence Personnel and Para Military Force under this special priority category. To get supply under this scheme, the application along with relevant documents should be submitted to Superintending Engineer/Rural Electrification and Improvement (Distribution), TNEB, 4th floor, Western wing, NPKRR Malaigai, 144, Anna Salai, Chennai-600 002 for registering in this special priority category."
