Metric	Fiscal 2025	Fiscal 2024	Fiscal 2023
Average Plant Availability (%)	98.30%	98.80%	98.68%
Average Internal Grid Availability (%)	99.59%	99.67%	99.23%
Average External Grid Availability (%)¹	99.68%	99.82%	99.23%

Note: (1) Average external grid availability is calculated as the weighted average based on external grid availability by fully operational project capacity across the portfolio as of the reported date.

Our performance across these operating parameters has resulted in an average plant load factor (“PLF”, meaning total electricity generated from the fully operational capacity divided by the maximum possible generation from the same capacity during the period of operation) across our portfolio, as illustrated below:

Power Evacuation for Operational Wind Power Projects

Operations and Maintenance for our IPP Wind Power Projects

We operate a hybrid O&M model that combines long-term service agreements with turbine manufacturers and our in-house operational capabilities to ensure the efficient, reliable, and cost-effective functioning of our wind power projects. Vestas Wind Technology India Private Limited and GERI provide comprehensive long-term O&M services, through contracts generally ranging from 5 to 20 years. In addition to the comprehensive services support from the OEMs, we have also developed a dedicated in-house O&M capabilities, that oversees maintenance activities across all our project sites. This in-house capability enhances operational oversight and enables direct access to real-time, unfiltered turbine generation data. Such access allows us to:

• continuously monitor turbine performance;
• conduct predictive and preventive maintenance;
• perform detailed performance analytics; and
• ensure transparency and accountability in vendor services.

The table below further details our O&M activities across our wind power projects:

Our expansive project portfolio as mentioned above also enables us to negotiate favourable contractual terms, including, but not limited to minimum availability guarantees ranging from 95% to 97%, backed by liquidated damages linked to revenue losses in case of non-compliance; reactive power consumption guarantees over defined 12 months periods, where non-compliance leads to reimbursement of additional import charges, up to a capped percentage of the O&M charges; access to real-time data from turbines without filtration or delay; and power curve warranty to ensure high generation during peak wind seasons; and blade cleaning services, which help in maintaining aerodynamic efficiency and improving overall generation output.

Our O&M strategy for our IPP wind power projects ensures that our assets remain in optimal health, reduces downtime, and enhances overall plant performance. By combining OEM expertise with our in-house capabilities, we aim to maintain greater control over performance, cost, and compliance, which supports long-term value creation from our renewable energy assets.

Since 2014, we have developed 11 wind power projects with an aggregate installed capacity of 399.10 MW. These consist of our six wind power projects aggregating an installed capacity of 203.20 MW and five wind power projects aggregating an installed capacity of 195.90 MW which were developed for other IPPs in India.

As part of our O&M for BoP services, we maintain BoP infrastructure such as pooling substations, extra-high-voltage (“EHV”) lines, unit substations, SCADA systems, civil infrastructure, and right of way for the access to the project site. These services are delivered through a combination of our in-house teams and specialised contractors. We also provide O&M services for BoP at nine wind power projects, with an aggregate installed capacity of 245.20 MW. All these projects were developed by us and are either owned by our Company or by other IPPs.

Wind Power - Operations & Maintenance (O&M) for Balance of Plant Business

We provide O&M services for our own wind projects and external projects. As part of this service, we manage the wind power projects in a professional, effective and safe way during the whole windfarm lifecycle. Proper SOPs are introduced for the smooth operation of windfarm activities and are regularly updated and released.

Our Asset Management function has the following wings:

Electrical

A key vertical of our asset management which plays an important role in maintaining all the electrical transmission equipment and hence it is the backbone of power generation and transmission. We are currently providing these services for our own projects as well as external customers, maintaining substations and electrical transmission lines in the wind farms with a team of highly skilled manpower. We put emphasis in better wind power plant operation by rendering the best service for our customers to achieve good grid availability.

SCADA

SCADA plays a major role in wind farms as it supports the supervisory function of a wind farm and continuously collects, stores and processes data from the entire wind power plant, including the wind turbines. Through the SCADA system, the WTG data will also be kept for future reference purpose, potentially allowing us to further study and understand the performance of the wind projects. We have a dedicated SCADA team and deliver proper operation and maintenance of SCADA and the wind farms’ IT systems, which currently manage these operations for our own projects only.

Powerica Analysis & Monitoring Centre (“PAMC”)

PAMC features a robust infrastructure with qualified engineers who monitor all WTGs on a 24/7 basis. The core focus is on the response time and restoration duration of any errors or malfunctions in the WTGs or transmission electrical equipment, whether managed by OEMs or subcontractors. PAMC ensures maximum productivity through real-time monitoring and effective analysis of WTGs using SCADA data. This includes power curve analysis, availability analysis, trend analysis, and error analysis. The performance of WTGs is meticulously tracked with a real-time analytical dashboard, and detailed MIS reports are prepared on a daily, weekly, and monthly basis. Additionally, PAMC maintains a comprehensive record of major component replacements or repairs in WTGs and electrical transmission equipment, providing daily progress updates to management. Currently, the PAMC related services are provided for our own IPP wind power projects and not for external IPP clients.

Power Forecasting & Scheduling:

Forecasting & Scheduling is a regulatory framework in India designed to manage the integration of renewable energy, particularly wind power, into the electricity grid. This mechanism ensures grid stability and optimizes power generation by requiring IPPs to forecast their generation and adhere to scheduled commitments. We have a well-organized infrastructure with qualified engineers monitoring all our substations on a 24/7 basis. The team focuses on regularly updating information such as available capacity, wind speeds, and current load to the qualified coordinating agency (the “QCA”). The forecasting and scheduling data shared by QCA is reviewed, and the team coordinates with QCA to minimize deviation charges. Additionally, the team analyzes past deviations and suggest corrective measures to enhance accuracy and grid compliance. Regular discussions with QCA and internal stakeholders help improve scheduling strategies, ensuring seamless integration of renewable energy into the grid while mitigating financial penalties under deviation settlement mechanism regulations. Currently, these services are being carried out for our own IPP wind power projects and not for external IPP clients.

Multibrand Spare Parts

Key terms of the Framework Agreement with Vestas for Supply of Multi-brand Spare Parts

Our Company had entered into a framework agreement dated July 2, 2024 with Vestas Wind Technology India Private Limited (“Vestas’) for purchasing certain spare parts and consumables from time to time, required for repair, upgradation and/or maintenance of multi brand wind turbines, either manufactured or procured by Vestas (“Framework Agreement”) which has been subsequently renewed on July 2, 2025 for a period of twelve months.
