India’s transition toward renewable energy is no longer limited to policy targets or environmental goals. Today, solar and clean energy projects are driven by financial performance, operational reliability, and long-term sustainability. As project sizes grow and investment risks increase, careful feasibility planning has become essential. At the center of this planning process lies the Techno-Economic Viability Study, commonly referred to as a TEV Study.

A TEV Study determines whether a renewable energy project can perform reliably under real-world conditions while delivering predictable financial returns. In India’s metro cities—where infrastructure density, electricity demand, and regulatory oversight are high—TEV Studies are not just helpful; they are critical for project success.

This blog explains why TEV Studies form the foundation of bankable renewable energy projects across India’s major metro regions.

Understanding the Real Value of a TEV Study

A TEV Study is a comprehensive evaluation that connects technical feasibility with economic performance. It goes beyond surface-level estimates and examines how a project will behave throughout its operational life, typically 20 to 25 years.

A robust TEV Study includes:

• Site feasibility and structural assessment

• Solar resource and climatic analysis

• System design and technology selection

• Energy generation forecasting

• Capital expenditure and operational cost analysis

• Financial metrics such as IRR, NPV, DSCR, and payback period

• Sensitivity analysis for key assumptions

• Regulatory and policy compliance review

• Identification of technical and financial risks

By combining these elements, TEV Studies provide clarity and confidence to investors, lenders, and developers.

Why Metro-Based Renewable Projects Carry Higher Stakes

Renewable energy projects in metro cities differ significantly from those in semi-urban or rural areas. While metros offer strong demand and higher electricity tariffs, they also present unique challenges that can impact project viability.

Common metro-specific challenges include:

• Limited rooftop or land availability

• Shading from neighboring buildings and infrastructure

• Structural limitations of older constructions

• Highly variable commercial and industrial load profiles

• State-specific electricity regulations and approval processes

• Grid congestion and evacuation constraints

Without a city-specific TEV Study, these challenges often result in inaccurate projections, execution delays, or financial underperformance.

TEV Study in Delhi: Overcoming Density and Compliance Challenges

Delhi’s high electricity tariffs make solar energy financially attractive for commercial, institutional, and service-sector users. However, dense urban development and regulatory complexity demand careful feasibility assessment.

A TEV Study in Delhi focuses on:

• Structural evaluation of rooftops, especially in older buildings

• Shadow analysis caused by nearby high-rise structures

• Assessment of net-metering and gross-metering feasibility

• Impact of dust, pollution, and temperature on energy generation

• Detailed load profiling for offices, hospitals, hotels, malls, and institutions

By addressing these factors early, TEV Studies help ensure consistent generation and stable financial outcomes in Delhi-based projects.

TEV Study in Chennai: Strengthening Industrial Energy Investments

Chennai is one of India’s leading industrial centers, hosting automotive manufacturing, electronics, textiles, and export-oriented industries. These sectors require reliable power and predictable energy costs.

A TEV Study in Chennai evaluates:

• Continuous industrial load patterns and peak demand behavior

• Suitability of captive and group-captive solar models

• Land feasibility for ground-mounted solar installations

• Substation capacity and power evacuation infrastructure

• Compliance with Tamil Nadu electricity regulations and open-access policies

For industrial investors, TEV Studies reduce operational risk and support long-term cost optimization.

TEV Study in Hyderabad: Improving Bankability Through Accurate Planning

Hyderabad’s renewable energy landscape benefits from strong solar irradiation and rapid growth in IT, pharmaceuticals, logistics, and commercial real estate. While technical feasibility is high, financial success depends on realistic planning.

A TEV Study in Hyderabad includes:

• Location-specific solar resource assessment

• Rooftop feasibility for buildings with heavy HVAC usage

• Financial modeling for captive and PPA-based systems

• Environmental and regulatory compliance checks

• Analysis of temperature-related efficiency loss and degradation

These elements help improve predictability, making projects more attractive to lenders and investors.

TEV Study in Bangalore: Supporting Reliable and Scalable Energy Systems

Bangalore’s energy demand is driven by IT parks, data centers, research facilities, and a growing electric vehicle ecosystem. These users require uninterrupted power and future-ready energy solutions.

A TEV Study in Bangalore focuses on:

• Feasibility of solar-plus-battery hybrid systems

• Load analysis for mission-critical operations

• Rooftop structural and microclimate assessment

• Integration of EV charging infrastructure

• Financial viability of hybrid and backup energy solutions

TEV Studies in Bangalore support both reliability and scalability, ensuring long-term value.

TEV Study in Pune: Enabling Sustainable Growth with Cost Control

Pune combines manufacturing strength with a growing IT and services sector. Energy demand is diverse and continues to expand with industrial development.

A TEV Study in Pune covers:

• Detailed industrial and commercial load mapping

• Comparison of captive, open-access, and hybrid solar models

• Land feasibility for medium- to large-scale installations

• Tariff analysis under Maharashtra’s regulatory framework

• Long-term savings projections and cash-flow analysis

This approach ensures that renewable energy investments remain scalable and financially disciplined.

TEV Studies and Access to Project Financing

One of the most important outcomes of a TEV Study is improved access to finance. Banks and financial institutions rely on TEV documentation to assess project risk and repayment capacity.

A lender-focused TEV Study provides:

• Verified energy generation forecasts

• Transparent cost assumptions and expenditure breakdowns

• Debt Service Coverage Ratio (DSCR) analysis

• Sensitivity testing for tariff and generation variability

• Clear identification and mitigation of risks

Projects supported by strong TEV Studies generally experience smoother loan appraisal and faster approvals.

Risk Mitigation Through TEV Studies

Renewable energy projects face multiple risks that can affect long-term performance if not addressed early. TEV Studies help identify and mitigate these risks during the planning phase.

Key risks addressed include:

• Overestimation of energy generation

• Underestimation of ca
