The Ahmedabad Municipal Corporation (AMC) has issued a tender for the development of a 75 MW (AC) grid-connected, ground-mounted solar PV project integrated with a 7.5 MW / 30 MWh Battery Energy Storage System (BESS) in Gujarat. Structured under Group Captive Mode in accordance with the Electricity Act 2003 and Electricity Rules 2005, the hybrid renewable installation is designed to supply clean energy across AMC’s municipal premises. Interested bidders must submit their final bids prior to the submission deadline of October 9, 2026.
Project Scope & Technical Specifications
Capacity & Operational Framework
The project combines a 75 MW (AC) ground-mounted solar PV plant with a 7.5 MW / 30 MWh BESS component under a “Group Captive” framework. Under this arrangement, AMC acts as the primary project owner, captive consumer, and off-taker. The setup allows AMC to utilize self-generated renewable power across its distributed municipal facilities to fulfill statutory renewable energy obligations and optimize long-term municipal operational energy costs.
Special Purpose Vehicle (SPV) & Commercial Structure
Project execution will be managed through a dedicated Special Purpose Vehicle (SPV), designated as the “Employer” under the legal contract framework. To satisfy statutory requirements for captive consumer status under Indian electricity regulations:
- Equity Distribution: AMC will retain a mandatory 26% equity stake in the SPV, while the successful bidder (contractor) will hold the remaining 74% equity share.
- Funding Ratio: Capital financing is structured on a 70:30 debt-to-equity ratio. The contractor is responsible for securing debt financing for up to 70% of the project cost, while the 30% equity contribution will be funded proportionally by both equity partners based on their respective shareholdings.
- Off-taker Contract: Upon project commissioning, AMC transitions into its operational role as the Off-taker. Commercial energy procurement will be governed by a formal Power Supply and Offtake Agreement (PSOA/PPA) executed between the SPV and AMC.
Turnkey EPC Responsibilities
The project is contracted on a turnkey basis with a fixed lump-sum EPC cost model. This commercial structure transfers total execution, grid connection, performance, and long-term operational maintenance risk onto the successful bidder. Key contractor duties include:
- Complete end-to-end design, engineering, procurement, equipment supply, construction, installation, testing, and commissioning.
- Full project management, procurement of all statutory clearances and environmental approvals, and comprehensive project insurance.
- Provision of all necessary materials, equipment, labor, and services required to reach the Commercial Operation Date (COD) and sustain plant availability throughout the operational lifespan.
- Design and construction of grid evacuation infrastructure and transmission lines up to the designated Gujarat Energy Transmission Corporation (GETCO) 132/220 kV Renewable Energy (RE) Integration Substation.
Metering and Delivery Points
The contractual framework explicitly establishes two distinct physical and operational nodes to delineate operational monitoring from commercial billing:
- Metering Point: Located at the 33 kV level, where plant performance indicators—specifically the Guaranteed Capacity Utilization Factor (CUF) and Net Electrical Energy Generation (NEEGG)—are continuously monitored and verified.
- Delivery Point: Located at the GETCO 132/220 kV substation, serving as the official commercial interface where grid scheduling, commercial settlement, and energy accounting take place.
Warranty & Degradation Standards
The successful contractor must comply with strict contractual minimum warranty terms, defect liability requirements, and long-term performance guarantees:
| Component | Minimum Warranty / DLP Period |
| Solar PV Modules (Product Warranty) | 10 Years |
| Solar PV Modules (Performance Warranty) | 25 Years (Min. 90% at Year 10; Min. 80% at Year 25) |
| Inverters | 10 Years (as per OEM) |
| Transformers & Switchgear | 10 Years |
| Battery Energy Storage System (7.5 MW / 30 MWh BESS) | 12 Years (as per OEM) |
| Overall PV Plant Defect Liability Period (DLP) | 120 Months (10 Years) |
Degradation Limits: Solar PV module efficiency loss is strictly capped at a maximum of 2.5% for the first operating year, and a maximum of 0.6% per annum across the remaining 24 years of the performance warranty period.
Land Footprint Constraint: AMC will provide a fixed land allocation for the project. If remedial solar module or storage additions are required over the 25-year plant life to correct output shortfalls and meet guaranteed generation metrics, all supplementary hardware must fit entirely within the original land boundary, as no additional land will be provided.
Key Tender & Compliance Details
Bidders must navigate a rigorous regulatory framework covering taxation, statutory labor welfare, and financial eligibility parameters:
- Taxation and GST Audit Timelines: The contractor assumes full liability for income, corporate, and municipal taxes. GST-compliant tax invoices must incorporate valid SAC/HSN codes alongside the SPV’s GSTIN. GST Adjustment Notes (Credit/Debit notes) must be issued within 15 days of identifying any billing discrepancy and no later than six months following the end of the corresponding financial year.
- Labor Regulations: Bidders must mandate compliance with statutory welfare levies, including the mandatory payment of CESS under the Building & Other Workers Welfare Cess Act, 1996.
- Eligibility & Bidding Terms: Specific financial thresholds—including required average annual turnover, net worth eligibility criteria, Earnest Money Deposit (EMD) amounts, and tender document fees—are detailed within the “Instruction to Bidders (ITB)” and Section V of the tender documentation.
