Techno Economic Viability (TEV) Consultant for Banks, NBFCs & Financial Institutions

SARK Engineers & Consultants provides independent techno-economic viability, technical due diligence and project appraisal support for banks, NBFCs, financial institutions, investors and project-financing teams.

The purpose of a TEV review is to determine whether a proposed or operating project is technically feasible, commercially realistic and capable of supporting the assumptions used for financing decisions.

Our reviews connect:

  • technology;

  • plant capacity;

  • process design;

  • utilities;

  • water and wastewater;

  • CAPEX;

  • OPEX;

  • project implementation;

  • environmental and regulatory requirements;

  • operating risks;

  • lender-model assumptions.

The assessment is led by Dr. Anubhav Gupta, Chemical Engineer and Chartered Engineer, with experience in financing-related technical assignments across industrial and infrastructure projects.

What Is a TEV Study?

A Techno Economic Viability study evaluates whether a project is technically sound and whether its technical assumptions support the proposed financial model.

It is not merely a financial review.

A lender-side TEV study may examine whether:

  • the selected technology is appropriate;

  • proposed capacity is realistic;

  • machinery and utilities are adequately sized;

  • CAPEX assumptions are credible;

  • OPEX assumptions are technically supportable;

  • implementation timelines are reasonable;

  • raw material, water, energy and utility requirements are realistic;

  • environmental and statutory requirements have been considered;

  • technical risks may affect repayment or project performance.

The purpose is to give the lender or investor an independent technical view before or during financing.

When Do Banks and Financial Institutions Need TEV Support?

Term Loan Approval

Where a bank or NBFC needs to validate:

  • project concept;

  • machinery;

  • capacity;

  • CAPEX;

  • utility requirement;

  • operating assumptions.

Project Expansion

Where an existing plant proposes:

  • capacity expansion;

  • new process line;

  • new utilities;

  • ETP/ZLD upgrade;

  • automation or modernization.

Acquisition or Investment

Where an investor needs to understand:

  • asset condition;

  • production capability;

  • technology risk;

  • compliance exposure;

  • future CAPEX.

Refinancing or Additional Funding

Where technical condition, remaining capacity or project viability needs independent verification.

Team Collaborating Indoors

Independent Lender-Side Technical Review

SARK approaches TEV assignments from the perspective of an independent technical advisor, rather than validating assumptions supplied by the project developer.

The review may challenge:

  • capacity claims;

  • unrealistic operating hours;

  • optimistic plant utilisation;

  • underestimated utility demand;

  • inadequate wastewater-treatment scope;

  • understated replacement CAPEX;

  • incomplete environmental compliance;

  • unsupported vendor guarantees.

The objective is not to make the project look stronger.

It is to identify where the technical reality differs from the financing assumption.

What Data Is Required for a TEV Study?

Project Documents

  • DPR;

  • feasibility study;

  • PFD/P&ID;

  • layout;

  • equipment list;

  • vendor offers.

Plant Data

  • machinery specifications;

  • production history;

  • utility consumption;

  • maintenance data;

  • wastewater data;

  • compliance records.

​Financial / Technical Inputs

  • CAPEX;

  • OPEX;

  • production assumptions;

  • utilisation assumptions;

  • utility costs;

  • projected revenues.

Regulatory Documents

  • CTE/CTO;

  • EC;

  • groundwater permissions;

  • pollution-control approvals;

  • statutory correspondence.

Why Financial Institutions Use Independent Technical Advisors

A borrower or project promoter may have a different perspective from a lender.

An independent technical advisor helps the lender evaluate:

  • whether technical assumptions are realistic;

  • whether project capacity can support projected cash flow;

  • whether utilities are adequate;

  • whether environmental systems have been properly costed;

  • whether additional CAPEX may be required;

  • whether implementation risks could affect repayment.

The value of the TEV study lies in converting engineering uncertainty into decision-useful lender information.
