On the Solar & BESS Segment for Rooftop applications across C&I, RTC, Hybrid, and FDRE Projects:

DC SLD Validation: We conduct rigorous re-validation of DC configurations to ensure alignment with inverter specifications and permissible DC voltage drops, all designed to guarantee high PR & CUF. Our approach integrates advanced protection schemes, seamless SCADA monitoring, and holistic consideration for O&M and asset management.

AC SLD Validation: Our scheme re-validation is tailored for LCOE fit and optimized block design, with a strategic focus on consistently meeting—or exceeding—contractual PR & CUF. We enforce robust LT & HT protection, implement decisive fault clearing mechanisms, ensure grid study code compliance, and underpin plant uptime with proactive spare management and superior O&M and asset management frameworks.

Auxiliary SLD: We re-validate auxiliary schemes with a focus on minimizing auxiliary power consumption, deploying advanced protection methodologies and fault clearing mechanisms. These measures are directed at ensuring plant uptime, along with efficient spare management and comprehensive O&M and asset management.

BESS Scheme: Our re-validation strategy ensures complete alignment with LCOE fit and optimized block design, encompassing both LT & HT protection, rigorous fault clearing mechanisms, and grid study code compliance. We also prioritize the minimization of DC to AC conversion losses and reinforce plant uptime through dynamic spare management and integrated O&M and asset management solutions.

Scheme Validation: Our elite validation approach meticulously assesses the bus scheme selection, ensuring strategic alignment from an LCOE optimization perspective and fortifying the protection architecture for uncompromised reliability. Each evaluation is future-ready, facilitating seamless digital substation transformation and guaranteeing absolute grid study code compliance. We drive maximized plant uptime through intelligent spare management and advanced O&M and asset management solutions.

Protection Engineering Review: We deliver a comprehensive, high-level review of power transformers, transmission lines, and the entire substation Balance of System (BoS). Our process is engineered to uphold best-in-class protection standards, safeguarding critical infrastructure with precision and foresight.

Equipment Weight Analysis: Our specialists conduct rigorous equipment weight analysis, ensuring every design is optimized to perfection while adhering to the most stringent design standards and state utility code guidelines. This guarantees not only compliance but also superior operational efficiency and asset longevity.

Earthing & Lightning Protection Review: Through an advanced validation of substation earthing and direct stroke lightning protection (DSLP) frameworks, we assure total system integrity. Our methodologies are rooted in the highest levels of compliance with IS, IEC, NEC, and IEEE standards, and are precisely adapted to satisfy demanding environmental and regulatory imperatives.

With Chakra Group’s premium substation re-validation, clients are assured of world-class engineering rigor, future-proof asset performance, and a clear pathway to sustainable operational excellence.

Our structural validation for Fixed Tilt and Single Axis Tracker (SAT) designs rigorously addresses every parameter, including soil bearing capacity (SBC), soil properties, wind speed, land undulation, corrosion classification, load distribution, and the system’s future adaptability. This comprehensive approach ensures engineering integrity and resilience under all site-specific conditions.

ICR (Inverter Control Room) & MCR (Main Control Room): We deliver meticulous building design validation for both ICR and MCR, guaranteeing full compliance with Indian Standards, all relevant specification requirements, and the spectrum of environmental influence factors. Our process ensures structural safety, operational excellence, and long-term durability.

Foundation Design Analysis: Our advanced foundation analysis covers all heavy equipment, including power transformers (PTR), inverter duty transformers (IDT), main HT panel outdoor platforms, wind turbine foundations, substation gantry towers, transmission line towers, and watch towers. Each design is validated for structural soundness, longevity, and strict adherence to the industry’s most demanding standards.

With Chakra Group’s premium structural analysis solutions, clients receive unparalleled assurance in the safety, compliance, and future readiness of their entire project infrastructure.

Our comprehensive energy generation validation process is designed to ensure a design fit model that maximizes operational outcomes. We conduct detailed assessments based on finalized PV module IEC reports and in-depth evaluation of inverter GTP and test reports. Every source of actual calculated losses is scrutinized, while our analysis encompasses LCOE optimization, plant unavailability risks, and overall bankability of the project.

The evaluation rigorously incorporates probability factors such as P50, P75, and P90, providing a transparent and risk-informed outlook. All findings are integrated into a robust project budget model that supports strategic investment decisions and long-term project viability.

Our rigorous evaluation process covers the complete spectrum of vendor-submitted documentation, including GTP (Guaranteed Technical Particulars), GA (General Arrangement) drawings, parts drawings, calculation sheets, design reports, QAP (Quality Assurance Plans), and type test reports. Each submission is meticulously validated to ensure technical excellence and full compliance for all key equipment associated with renewable power plants, BESS (Battery Energy Storage Systems), transmission lines, and substations.

This elite approach guarantees that only thoroughly vetted, high-quality components are integrated into your critical infrastructure, securing operational reliability and long-term asset value.
