DMRC Installation – Case Study

What the DMRC -project is all about DMRC wanted to put up its first 500 KWp Solar power plant at Sector 21 Dwarka Metro Station. Sun. Edison was the successful bidder under SECI tender for subsidy - Delhi State Proposed an apt solution with attractive tariff (flat for first 3 years and subsequently an increase of till 15 years and thereafter a flat tariff till 25 years. Helping in hedging the rising power costs for 25 years No hassles for DMRC to maintain the system in terms of O&M and warranty management since the asset owned by Sun. Edison DMRC has to pay for only energy generated

Challenges Discussion on the terms of the PPA Installation was to be done at rooftop of a fully functional metro station Had stiff timelines to meet. No penetration type structure solution to be provided. Cable routing system was critical. Interconnection to the existing LT system

Timelines Receipt of LOI : 29 th January 2014 PPA signing – 20 th February 2014 Commencement of work – 16 th June 2014 Commissioning – 27 th June 2014 ( In record 11 days)

Technical Details Solar Modules –Multicrystalline type - 300 Wp - 1670 Nos 20 KW String Inverters– 20 Nos Penetration less type Structures – Delta racks AC Side - 3. 5 C X 16 Sqmm and 3. 5 C X 300 Sqmm- Al XLPE FRLS cable Data Monitoring System – Sun. Edison Energy & Environmental Data Systems ( SEEDS) Connectivity at 415 V to the existing LT panel

Way forward Sun. Edison is executing similar 1. 5 MWp project at Yamuna bank Yard and Station
