## Key Details at a Glance

| Parameter | Details |
|———–|———|
| **Petition No.** | 10/2026 |
| **Petitioner** | Tata Power Delhi Distribution Ltd. (TPDDL) |
| **Project Type** | Firm and Dispatchable Renewable Energy (FDRE) with Energy Storage System (ESS) |
| **Base Capacity** | 200 MW |
| **Greenshoe Option** | Additional 200 MW (total potential: 400 MW) |
| **Governing Guidelines** | MoP Guidelines for FDRE with ESS (dated November 14, 2025) |
| **Reason for Amendments** | Queries received from bidders during tender process |
| **Relief Sought** | Approval of amendments to Bidding Documents |
| **DERC Action (April 7, 2026)** | Petition admitted; order reserved |

## Business Context

### 1. Why This Tender Matters

– **First-of-its-kind for TPDDL** under the new November 2025 central guidelines
– **FDRE + ESS** ensures round-the-clock or peak-hour firm power, unlike intermittent solar/wind
– **Greenshoe option** provides flexibility to scale up to 400 MW without re-tendering
– **Bidder queries** indicate active participation, likely from large RE developers with storage capabilities

### 2. Regulatory Framework

The tender is governed by the **Ministry of Power’s “Guidelines for Tariff Based Competitive Bidding Process for procurement of Firm and Dispatchable Power from Grid Connected Renewable Energy Power Projects with Energy Storage Systems”** dated **November 14, 2025** – a relatively new framework.

### 3. Comparison with BRPL’s SJVN Procurement (Petition No. 78/2025)

| Parameter | TPDDL (Petition 10/2026) | BRPL (Petition 78/2025) |
|———–|—————————|————————-|
| **Capacity** | 200 MW + 200 MW greenshoe | 600 MW (later reduced to 350 MW) |
| **Source** | New tender under Nov 2025 guidelines | Direct allocation from SJVN’s project |
| **Status** | Amendments to bid documents pending approval | Approved for 350 MW at ₹6.74/kWh |
| **Key Lesson** | Seeking early approvals for amendments | Capacity lost due to regulatory delay |

**Strategic Insight:** TPDDL is proactively seeking approval for **bid document amendments** *before* finalizing the tender, unlike BRPL which sought approval *after* winning allocation, leading to capacity erosion. This is a **better regulatory strategy**.

## Regulatory Timeline & Next Steps

| Date | Event |
|——|——-|
| **April 7, 2026** | Hearing held; Petition admitted; order reserved |
| **Future date** | DERC may seek clarifications from TPDDL officers |
| **Future date** | DERC to issue final order approving (or modifying) amendments |
| **Post-approval** | TPDDL to issue final bidding documents and proceed with tender |

> **Note:** Since the order is reserved, bidders should monitor the DERC website for the final order before submitting bids.

## Business Implications

### For TPDDL (DISCOM):
– **Proactive regulatory engagement** reduces risk of post-bid disputes
– **Greenshoe option** provides cost-effective capacity expansion without re-tendering
– **Amendments based on bidder queries** will improve bidder participation and tariff discovery
– **Risk:** If DERC takes time to approve, similar capacity erosion risk as BRPL (though amendments are less time-critical than final PSA approval)

### For RE Developers (Bidders):
– **Monitor DERC order** – Final bid document terms will determine project viability
– **Key terms to watch:** Firmness guarantee (e.g., 90% peak hour availability), storage duration, charging power cost allocation
– **Greenshoe option** – Opportunity to secure up to 400 MW instead of 200 MW
– **Transmission waiver** – Projects commissioned by June 30, 2028 get 100% ISTS waiver; this affects landed tariff

### For Regulators (DERC):
– This is a **test case** for the new November 2025 FDRE guidelines
– **Fast approval** will encourage other DISCOMs to use this framework
– **Pre-approval of bid documents** (as sought here) is more efficient than post-facto PSA approval (as in BRPL case)

### For Other DISCOMs:
– Use this as a **template** for seeking early approval of bid documents
– Incorporate greenshoe options in tenders for flexibility
– Learn from BRPL’s capacity loss – seek approvals **before** or **parallel to** bidding
