Railway Energy Management Company Ltd. (REMCL), acting as the authorized representative on behalf of Mumbai Railway Vikas Corporation Ltd. (MRVC), has issued a tender for 1.57 MW (1,570 kW AC / 1,949.96 kWp DC) of grid-connected rooftop solar photovoltaic (PV) systems across four Central Railway stations in Maharashtra. Bids for the turnkey development across Panvel, Karjat, Badlapur, and Chikhloli stations must be submitted online by October 21, 2026. The tender supports Indian Railways’ overarching mandate to integrate renewable energy across suburban transit networks and achieve Net Zero Carbon Emissions by 2030.

Key Tender Details & Capacity Breakdown

  • Total Feasible Solar Capacity: 1,570 kW AC (1,949.96 kWp DC).
  • Total Potential Capacity Identified: 5,113 kWp DC across surveyed assets.
  • Evacuation Voltage: Low-voltage 415 Volts grid connection.
  • Target Sites: Station decks, cover-over-platforms (COP), and roofs/sheds across four key suburban stations.

Station-Wise Feasible Capacity Allocation

Railway Station NameDistrictFeasible Capacity (kW AC)Feasible Capacity (kWp DC)

BadlapurThane250 kW313.20 kWp
ChikhloliKalyan / Thane250 kW295.80 kWp
Total—1,570 kW1,949.96 kWp

Note on Capacity Constraints: While preliminary engineering surveys identified a cumulative solar potential of 5,113 kWp DC across the four stations, the tender’s feasible capacity is scaled to 1,570 kW AC due to structural readiness and grid constraints. Several surveyed structures—such as Panvel COP CST End (306 kWp), Panvel Deck A (325 kWp), and Chikhloli Platform COP (1,058 kWp)—are currently unbuilt or under early construction. Furthermore, feasible plant sizing is restricted by station sanctioned load caps (e.g., Karjat at 651 kW; Badlapur and Chikhloli at 250 kW) and proximity to primary metering points.

Equipment & Technical Specifications

  • PV Modules: High-efficiency 580 Wp Mono-PERC modules sourced exclusively from manufacturers listed under MNRE’s Approved List of Models and Manufacturers (ALMM Class I & Class II), adhering strictly to Class 1 Make in India content requirements.
  • Inverters: Commercial-grade string inverters compliant with Class 1 Make in India regulations.
  • Inverter Breakdown by Site:
    • Panvel: Four 100 kW inverters and one 20 kW inverter.
    • Karjat: Six 100 kW inverters and one 50 kW inverter.
    • Badlapur: Two 100 kW inverters and one 50 kW inverter.
    • Chikhloli: Two 100 kW inverters and one 50 kW inverter.
  • Solar Resource Profile: Global Horizontal Irradiance (GHI) across project locations ranges between 1,790.6 kWh/m² at Karjat and 1,794 kWh/m² at Panvel, Badlapur, and Chikhloli (based on METEONORM 8.2 data), providing stable, high-yield generation parameters.
  • Existing Solar Infrastructure: Panvel Station currently operates 365 kW (166 kW + 199 kW) of installed rooftop solar capacity, restricting additional feasible expansion to 420 kW AC within its 785 kW sanctioned load limit.
  • Commercial & Tariff Context: Applicable DISCOM landed electricity tariffs across the sites range from ₹7.64/kWh (MSEDCL) and ₹12.86/kWh (CIDCO) at Panvel to ₹10.00/kWh at Karjat and Chikhloli, and up to ₹13.29/kWh for LT public service connections at Badlapur. These rates offer significant operational offset value against grid power procurement for Central Railway.
  • Grid Interconnection: Power evacuation and net-metering integration established at low-voltage 415 V line terminals.

Scope of Work and Institutional Roles

Scope of Work for Winning Bidder
