Scope of Work:

  • The Tender is invited for Design, Engineering, Supply & Procurement, Erection, Testing, Commissioning and Comprehensive Operation & Maintenance for 5 (five) years for 406 kw (ac) grid connected rooftop solar photovoltaic power project on rooftop of various buildings at two locations (i) Site 1- Apparel park depot (206 kw) and (ii) Site 2- Gyaspur depot (200 kw) of Gujarat Metro Rail Corporation (GMRC) ltd, Ahmedabad in the state of Gujarat.
  • In grid connected solar photo-voltaic (PV) systems, electricity generated is fed into the building loads that are connected to the grid through a service connection with surplus energy being fed into the grid and shortfall being drawn from the grid.
  • Grid-connected solar PV systems have no battery storage and will not work during grid outage. For buildings with grid-connected solar PV systems, the service connection meter needs to be of the bidirectional type, whereby import kWh and export kWh are separately recorded.
  • The modules should be manufactured in India only. Rest of the components can be procured from any source. However these items should meet the Technical specification and standards mentioned in RFP. The Bidder shall be obligated to perform following Scope of Work in relation to the Project. The Scope of Work of the Bidder includes, but is not limited to, the following:

Project Development:

  • Design, develop, procure, construct and commission, operate and maintain various roof mounted SPV power packs totalling to capacity of 406 kW (AC) (Site 1-206 kW and Site 2- 200 kW) , which includes, but is not limited to the following:
  • Solar PV modules.
  • Components and parts used in solar PV systems should conform to the BIS or IEC or other international specifications, wherever such specifications are available and applicable.
  • Mounting frames, structures, array foundation (grouting on terrace), earthing grid design, and module interconnection.
  • All System Junction boxes.
  • Power Conditioning Units (PCU) with monitoring.
  • MPPT – Max power point tracking built in the PCU
  • Appropriate AC power evacuation panels or inverters, according to Project Site requirements, with bus bars (in-built or otherwise) and circuit breakers.
  • The nominal steady electrical characteristic of the system are as follows:
    • Single/ Three phase AC at 50 Hertz plus or minus 0.5 Hertz
    • Nominal voltage of 230 V/415V/11KV with +10% to -12.5% variation.
  • Protection/isolation systems.
  • Power and Control Cables.
  • Earthing system for PV Array, DC power system, lightning protection system.
  • Data monitoring system with remote monitoring facilities (Completely in scope of bidder).
  • Transportation, unloading, and loading of all equipment at Project Site.
  • Project Management including adherence to all requisite safety practices.
  • The Project shall be designed and capable of being synchronized and within a frequency range of 47.5 to 52 Hz and voltage of 230V/415V/11kV
  • Short circuit rating: As a part of the detailed design process, the Solar Company shall calculate the short circuit rating (minimum and maximum), and supply this information to the Procurer
  • Fire fighting (fire extinguisher and sand bucket with stand)
  • Making arrangements for module cleaning in the plant area with cleaning mechanism;
  • Control room/ panel (whichever may be found appropriate) for the plant built in suitable material, with proper ventilation for temperature control of the equipment and serviceability within the building. Alternatively, the existing meter room can be utilized after proper designing and approvals of the building owner (GMRC).

Mode of Execution:

  • The entire work shall be executed on turnkey basis. Any minor item(s) not included in the schedule but required for completion of the work shall have to be carried out/ supplied without any extra cost.
  • Such works, not listed in the schedule of works but elaborately described to perform or to facilitate particular operation(s) required for completion of the project shall be deemed to have been included in the scope of this work and the Contractor shall supply, install the same without any extra cost.

Programme of Work:

  • The Contractor shall submit the programme of work within 3 days from the date of receipt of Letter of Award.
  • The programme shall include a Bar Chart indicating there in the starting position and completion date of each of the major items of work.
