### **Subject Matter**
Petition seeking a mechanism to implement **Tariff Order No. 05 of 2024 (dated 31.08.2024)** by **relaxing the requirement of installing Remote Terminal Units (RTUs) at each Wind Turbine Generator (WTG)** in Gujarat.

### **Background**
* **28.03.2025 (Interim Order):** Commission allowed Petitioner to commission its **30 MW WTGs** using **SCADA gateway** for real-time data (instead of RTU at each WTG), subject to final outcome.
* Petitioner filed an **affidavit (27.05.2025)** confirming that its OEM can provide **SCADA data (real-time, per WTG)** via pooling stations, ensuring accuracy and utilization.
* Similar interim reliefs were extended to other developers (KP Energy, ACME Pokhran Ltd., Suzlon Global Services Ltd.) for consistency.
* The **five key parameters** required by SLDC on real-time basis from each WTG:
1. MW
2. MVAR
3. Voltage (R-Y phase)
4. Frequency
5. Circuit Breaker Status (digital)
—
### **Respondent Submissions**
* SLDC confirmed Petitioner integrated **LVRT, HVRT, Wind Speed, and Wind Direction data** at pooling station RTU through SCADA.
* **SOE Buffer Test** at WTG level is pending, with commitment to complete by **08.07.2025**.
* SLDC maintained commissioning is **only interim** and subject to final order, emphasizing need for continuous **real-time data** on five parameters.
—
### **Commission’s Observations**
* Petitioner agreed to provide real-time SCADA data for each WTG.
* SLDC did not raise objections provided data is available as required.
* Commission noted the consistency of relief extended to multiple developers to maintain equitable regulatory treatment.

### **Order**
* Both parties directed to **complete pleadings within 2 weeks** and file **written submissions within 1 week thereafter**, serving copies to each other.
