  7. 7. INTRODUCTION AND BACKGROUND Tender Documents for 3 MW Grid Connected Solar PV Project at Diu August 2013 6 | P a g e 1.1 INTRODUCTION TO ELECTRICITY DEPARTMENT OF DAMAN AND DIU Daman and Diu are Union Territories embedded within the State of Gujarat on the west coast of India. The administration of the Union Territory is head by Administrator. Electricity Department of Daman & Diu (herein after referred as ED- DD) is part of the administration of Union Territory of Daman & Diu. The ED-DD is headed by the Secretary (Power). ED-DD is mainly engaged in the procurement, transmission and distribution of electricity to the various categories of consumers. The ED-DD does not own or operate any generating stations. Hence, based on allocation, power is drawn from the central sector power stations. The ED-DD is engaged in the work of construction, operation and maintenance of power transmission and distribution system which caters to power demand of various categories of consumers. To promote renewable energy, bringing awareness to green power, and to fulfill Renewable Energy Obligation (RPO), ED-DD wants to setup solar PV based grid connected power generation plants. ED-DD has planned to setup 3 MW Grid connected Solar PV project at Fudam, Diu. 1.2 ED-DD PROFILE The ED-DD is a small utility catering to average demand of around 250 – 300 MW. As shown in Figure. 1, bulk power supply is drawn from the Central Sector Power Stations. At present, the Daman gets power from Ambethi 400/220 KV at Ambethi- Magarwada 220 KV double circuit lines. It also draws power from 220 / 66 kV Vapi (GETCO) substation through 66 KV Double circuit line. Diu gets power via 66 kV double circuit lines emanating from GETCO network. Daman has population of around 2.42 Lakhs as per 2011 census. The present power allocation of Daman & Diu is 270 MW. Against this allocation, the U.T is getting only an average of 170 - 240 MW as a daily power schedule. The actual demand of the UT is about 255 MW (restricted) and 280 MW (Un-restricted). Diu has population of around 42000 as per 2011 census. Diu gets power from 220 KV Kansari Sub-station and 66 KV Una sub-station of GETCO through 66 KV Double circuit line. The peak demand of Diu is nearly 10 MVA.
