## **Key Observations**

### 🥇 **Most Successful Bidders**
– **Sunanda Solar Balaji Energy** – Won 2 projects (P-3 at ₹3.80, P-5 at ₹3.42) – both in Assam
– **Kshitij Kumar Choudhary** – Won P-2 (Sikkim) at ₹4.67
– **Sach Collection Point** – Won P-1 (Sikkim) at ₹4.67
– **Arka Sustainable Energy Solutions** – Won P-4 (Manipur) at ₹4.67

### **Tariff Range (L1)**
| Location | Tariff (₹/kWh) |
|———-|—————-|
| IIT Guwahati (2,000 kW) | **3.42** (lowest) |
| IIIT Guwahati (125 kW) | 3.80 |
| Sikkim (550 & 700 kW) | 4.67 |
| Manipur (165 kW) | 4.67 |

> **Northeast tariff trend**: Larger projects (IIT Guwahati) attracted lower tariffs. Smaller projects in remote NE states commanded higher tariffs (~₹4.67).

### **Consistent Performer (non-L1)**
– **Nithin Sai Constructions** – Ranked 3rd or 4th in multiple projects (₹4.80–₹5.00)
– **Stockwell Solar Services** – Consistently in top 5–6 ranks
– **NexGen Digital Infrastructures** – Appeared across multiple projects
