The Rajasthan state distribution utilities—Jodhpur, Jaipur, and Ajmer Vidyut Vitran Nigams (JdVVNL, JVVNL, and AVVNL)—have issued e-procurement tenders for pilot-based, small-scale standalone decentralized Battery Energy Storage Systems (BESS). The cumulative tendered capacity across the three utilities is 172 MW / 688 MWh, with an estimated capital valuation exceeding ₹680 Crore. Rajasthan Rajya Vidyut Utpadan Nigam Limited (RUVITL) is acting as the nodal agency on behalf of the DISCOMs to execute the Battery Energy Storage Purchase Agreement (BESPA) with successful developers. These systems are to be connected at identified 33/11 kV grid substations to support decentralized grid operations.
DISCOM-Specific Capacity and Financial Breakdown
The procurement is structured across the three distribution zones with specific bidding constraints and valuations:
- JdVVNL: 150 MW / 600 MWh capacity, representing the largest share of the rollout. The tender comprises 150 individual 1 MW / 4 MWh units bundled into 12 packages distributed across multiple locations. The estimated capital cost is approximately ₹630 crore. Bidders are permitted to participate in a minimum of one and a maximum of three packages.
- JVVNL: 12 MW / 48 MWh capacity, consisting of 12 units of 1 MW / 4 MWh each. The estimated cost for this pilot is approximately ₹50.40 crore. Bidders may bid for a minimum of one and a maximum of six projects.
- AVVNL: 10 MW / 40 MWh capacity with a specified tender value of ₹42 crore. Bidders are permitted to bid for a minimum of one project and a maximum of five projects.
Technical Parameters and Operational Requirements
All BESS units must comply with state-mandated technical specifications and operational protocols:
- Discharge Duration: All units are required to maintain a 4-hour discharge configuration.
- Cycle Frequency: Systems must be capable of a minimum of one and up to two charge-discharge cycles daily based on substation demand.
- Operational Lifetime: Minimum of 6,300 cycles (averaging 420 cycles annually) over the 15-year contract term.
- Efficiency and Availability: Developers must provide a guaranteed minimum monthly AC-to-AC round-trip efficiency (RtE) of 85% and a minimum annual system availability of 95%.
- Depth of Discharge (DoD): To maintain safety buffers, the Battery Energy Storage System Developer (BESSD) may limit the system to a maximum threshold of 90% DoD.
- Dispatch and Scheduling: Power will be made available on an “on-demand” basis. While intended to support morning (6:00 AM – 8:00 AM) and evening (6:00 PM – 10:00 PM) peak hours, DISCOMs retain control over day-ahead scheduling.
- Commissioning Protocol: For initial commissioning and testing, DISCOMs will provide first-time charging energy for a 72-hour window prior to the Commercial Operation Date (COD) at no cost. Partial commissioning of an individual awarded project is not permitted.
Commercial Terms and Bidding Prerequisites
Bidders must fulfill the following financial obligations and regulatory requirements:
- Non-refundable Fees: A tender document fee of ₹11,800 and a RISL processing fee of ₹2,950 per tender.
- Security Deposits: An Earnest Money Deposit (EMD) of ₹2.10 lakh per MWh and a Performance Bank Guarantee (PBG) of ₹5.25 lakh per MWh.
- Net Worth Requirement: Bidders must demonstrate a minimum net worth equivalent to 20% of the estimated capital cost for the current financial year.
- Domestic Content Requirement: Under the “Make in India” policy, it is preferred that at least 20% of the total system cost—including equipment, components, and associated systems—be sourced from domestic manufacturers.
