What Is a TEV Report and Why Do Banks Require It?
A manufacturing project may look attractive in a financial model. Production may be projected to increase, margins may appear healthy and the proposed machinery may seem capable of delivering the required output.
For a lender, however, one fundamental question remains:
Can the project actually perform technically well enough to support the financial assumptions on which the loan is being considered?
This is where a Techno Economic Viability Report, commonly called a TEV Report, becomes important.
A TEV study connects the engineering reality of a project with its economic assumptions. It examines whether the proposed technology, plant capacity, machinery, utilities, project cost, operating expenses, implementation schedule and regulatory requirements are reasonably aligned with the business projections presented to a bank or financial institution.
Banks in India do use external TEV consultants for such assignments. State Bank of India, for example, has issued empanelment notices specifically for consultants undertaking Techno Economic Viability studies for the bank, while SIDBI's published scope for TEV consultants includes reviewing project documents, validating the reasonableness of project costs, assessing technical feasibility and technology, examining supplier credibility and reviewing required approvals and licences.
For lenders, therefore, TEV is not simply another project document. It is an independent technical challenge to the assumptions behind the proposed investment.
Businesses, lenders and investors requiring such an assessment can explore SARK Engineers & Consultants' Techno Economic Viability (TEV) and Technical Due Diligence Services.
What Does TEV Mean?
TEV stands for Techno Economic Viability.
A TEV study examines a project from two connected perspectives:
Technical Viability
Can the proposed facility realistically:
manufacture the stated product?
achieve the proposed production capacity?
operate with the selected machinery and technology?
obtain the required raw materials and utilities?
manage its water, wastewater and environmental requirements?
be constructed and commissioned within a realistic schedule?
Economic Viability
Do the technical assumptions support the projected economics of the project?
For example:
Is the proposed CAPEX adequate?
Are energy and utility costs realistic?
Is expected plant utilisation achievable?
Has sufficient maintenance expenditure been considered?
Are pollution-control and environmental costs included?
Could a technical bottleneck materially reduce expected production?
The lender's financial model and the engineering design therefore cannot be evaluated independently.
A technically weak assumption can eventually become a financial risk.
Why Do Banks Require TEV Reports?
Banks lend against an expectation that a project will generate sufficient economic activity and cash flow to service its debt.
Financial statements alone cannot establish whether a proposed industrial plant will actually deliver that performance.
Banks therefore need to understand the technical basis behind the numbers.
RBI guidance on infrastructure financing has historically emphasised that banks and financial institutions should finance projects that are technically feasible, financially viable and bankable, with adequate appraisal expertise covering technical feasibility, financial viability and risk analysis. Reserve Bank of India
A TEV study helps answer questions such as:
Is the proposed production capacity realistic?
Is the selected technology proven and appropriate?
Is the machinery adequate?
Has the borrower underestimated the project cost?
Are power, steam, water and other utilities sufficient?
Are operating costs based on realistic engineering assumptions?
Are pollution-control systems adequately sized and budgeted?
Are important statutory approvals missing?
Can the project realistically achieve its proposed commissioning schedule?
The answers may materially affect the financing decision.
What Does a TEV Consultant Review?
The exact scope varies according to the industry, loan structure, project stage and lender's requirements.
A comprehensive lender-side TEV assessment may examine the following areas.
1. Project Concept and Technology
The consultant reviews whether the proposed process and technology are appropriate for:
intended product;
proposed capacity;
raw-material characteristics;
operating conditions;
project location;
level of automation;
expected product quality.
Questions may also arise regarding technology maturity, supplier support and obsolescence risk.
SIDBI's published TEV scope specifically includes review of the technical feasibility of the project, proposed technology, qualitative aspects and supplier credibility. SIDBI
2. Plant Capacity
Capacity deserves considerably more attention than simply accepting the number stated in a DPR or vendor quotation.
A TEV consultant may distinguish between:
Design capacity — theoretical design basis of equipment.
Installed capacity — capacity represented by the installed machinery.
Demonstrated capacity — output actually achieved, where an operating plant exists.
Sustainable capacity — production that can reasonably be maintained under normal operating conditions.
Bottleneck capacity — maximum output permitted by the weakest stage in the production chain.
For example, a production line may contain equipment theoretically capable of 100 tonnes per day while its boiler, dryer, filtration system or wastewater-treatment plant can support only 70 tonnes per day.
For the lender, 70 TPD may be the more relevant number.
SARK also undertakes Industrial Process Consulting and Process Efficiency & Yield Optimization, which can support deeper investigation where production capability or bottlenecks require engineering review.
3. Plant and Machinery
The machinery review may consider:
make and model;
capacity;
equipment configuration;
compatibility between equipment;
redundancy;
supplier;
procurement status;
installation requirement;
utility demand;
critical spares;
expected operating life.
For an existing plant, the review may additionally consider operating condition, maintenance history and remaining useful capability.
Machinery assessment becomes especially important where financing involves expansion, refurbishment, imported machinery or an existing manufacturing facility.
4. CAPEX Validation
One of the most important questions for a lender is:
Has enough money actually been budgeted to complete the project?
A project's headline machinery quotation does not represent its entire project cost.
TEV review may therefore examine:
process equipment;
civil works;
utilities;
electrical systems;
piping;
instrumentation;
automation;
installation;
commissioning;
storage;
laboratory infrastructure;
ETP/STP/ZLD systems;
pollution-control equipment;
fire and safety systems;
engineering;
contingency.
SIDBI's published TEV scope includes an in-principle validation of the reasonableness of cost components considered under a project. SIDBI
An underestimated project cost can result in a funding gap during implementation, which can itself become a lender risk.
5. OPEX Review
A project may be technically feasible but economically unattractive if operating costs have been underestimated.
Depending on the industry, important OPEX components may include:
raw materials;
electricity;
fuel;
steam;
water;
cooling;
compressed air;
chemicals;
manpower;
maintenance;
consumables;
wastewater treatment;
sludge or waste disposal.
Instead of accepting an aggregate operating-cost figure, the TEV consultant should examine the engineering basis behind major cost assumptions.
6. Utilities
Utility limitations are among the easiest ways for a theoretically adequate production line to fail to achieve its expected output.
A lender-side review may therefore examine:
Electrical Power
connected load;
operating load;
sanctioned supply;
transformer capacity;
captive generation;
power quality.
Steam and Fuel
boiler capacity;
pressure and temperature requirement;
fuel availability;
fuel consumption;
condensate recovery.
Water
fresh-water requirement;
source availability;
process consumption;
cooling demand;
reuse potential.
Cooling
cooling-tower capacity;
chiller capacity;
seasonal conditions;
process heat load.
Compressed Air and Other Utilities
A production line cannot sustainably operate beyond the capacity of its supporting utilities.
Where deeper utility analysis is required, the review can connect with Energy Audit Services and Industrial Water Audits.
7. Water, Wastewater and Pollution Control
Environmental systems are sometimes treated as secondary infrastructure in project estimates.
For many industries, they are critical production infrastructure.
A TEV review may examine:
water balance;
wastewater quantity;
wastewater characteristics;
ETP capacity;
STP capacity;
treated-water reuse;
RO recovery;
ZLD requirement;
sludge generation;
waste disposal;
pollution-control CAPEX;
operating cost.
An inadequate ETP can limit production just as effectively as an undersized manufacturing machine.
For projects with significant wastewater requirements, SARK's ETP & Industrial Wastewater Treatment Consulting and ETP Feasibility Report services can provide deeper engineering assessment.
8. Environmental and Statutory Approvals
Technical viability also depends on whether the project can lawfully operate at the proposed capacity and location.
Depending on the project, relevant requirements may include:
Consent to Establish;
Consent to Operate;
Environmental Clearance;
groundwater permissions;
hazardous-waste authorisation;
fire approvals;
factory-related permissions;
sector-specific statutory requirements.
SIDBI's TEV scope explicitly includes reviewing clearances, approvals, permits and licences obtained or required for a project. SIDBI
SARK's Environmental Compliance Consulting can support detailed evaluation where environmental permissions materially affect project viability.
9. Project Implementation Schedule
Financing models usually assume a date from which commercial production begins.
If that date is technically unrealistic, revenue and debt-servicing assumptions may also become unrealistic.
The TEV consultant may review:
engineering status;
procurement lead times;
civil construction;
machinery delivery;
installation;
utility readiness;
statutory approvals;
commissioning;
trial production.
The objective is to determine whether the proposed Date of Commencement of Commercial Operations is technically achievable.
10. Technical Risks
A good TEV report should not merely repeat project information.
It should identify the conditions that could cause the project to underperform.
Examples include:
single-source raw material;
unproven technology;
inadequate utilities;
aggressive utilisation assumptions;
dependence on one vendor;
wastewater-treatment inadequacy;
missing approvals;
underestimated CAPEX;
insufficient redundancy;
unrealistic implementation schedule;
weak operating capability.
The lender can then determine whether these risks require mitigation, additional information or modification of the financing structure.
How Is a TEV Report Different From a DPR?
This distinction is particularly important.
DPR — Detailed Project Report
A DPR is generally prepared for the project.
It explains the proposed business and usually presents:
project concept;
technology;
capacity;
machinery;
project cost;
implementation schedule;
projected operations;
financial assumptions.
It is therefore principally a project-development document.
TEV — Techno Economic Viability Report
A lender-side TEV study evaluates the project from an independent appraisal perspective.
It asks:
Are the assumptions in the project documentation technically reasonable?
The TEV consultant should therefore be prepared to challenge:
capacity;
technology;
vendor claims;
CAPEX;
OPEX;
utility consumption;
implementation timeline;
environmental assumptions.
The distinction can be summarised simply:
A DPR states what the project proposes to achieve.
A TEV study evaluates whether those assumptions are technically and economically credible.
TEV Is Also Different From Technical Due Diligence
The two services overlap, but their emphasis can differ.
A TEV study usually evaluates whether the proposed project is technically and economically viable for financing.
A technical due-diligence study often focuses more heavily on identifying:
hidden technical risks;
asset condition;
capacity limitations;
deferred maintenance;
compliance exposure;
future CAPEX;
technology risk.
Technical due diligence can therefore be particularly relevant to:
acquisition;
refinancing;
restructuring;
expansion financing;
investment in an existing facility.
What Information Is Usually Required for a TEV Study?
The consultant may request documents such as:
Project Documentation
DPR;
feasibility report;
process flow diagrams;
plant layout;
equipment list;
vendor quotations.
Production Information
proposed capacity;
operating hours;
product mix;
raw-material requirement;
yield assumptions.
Utility Information
electricity;
fuel;
steam;
water;
compressed air;
cooling.
Financial-Technical Inputs
project CAPEX;
operating-cost assumptions;
production assumptions;
plant utilisation;
implementation schedule.
Regulatory Documents
approvals;
licences;
consent documents;
environmental records;
groundwater permissions where applicable.
For an existing plant, historical production, maintenance and utility records can significantly improve the quality of the assessment.
Does Every Bank Loan Require a TEV Report?
No.
The requirement depends on factors such as:
lender policy;
project size;
industry;
complexity;
loan structure;
project stage;
perceived technical risk.
However, major banks and financial institutions maintain mechanisms for engaging TEV consultants where such assessment is considered necessary. SBI's published notices, for example, specifically provide for empanelment of external TEV consultants and identify sectors including transport infrastructure, power and renewable energy, hospitals, telecom, cement, fertilisers, pharmaceuticals, mining, steel, electric vehicles, chemicals, commercial real estate and logistics. State Bank of India
This demonstrates how widely the TEV concept extends beyond any single industry.
Who Should Prepare a TEV Report?
A meaningful TEV review requires more than financial modelling.
The evaluator should be capable of understanding:
industrial processes;
machinery;
utilities;
production capacity;
project implementation;
CAPEX/OPEX;
environmental systems;
operating risks.
For specialised projects, additional domain experts may be required.
Banks themselves recognise this need for technical competence. SBI's published eligibility criteria for TEV consultants refer to a track record in industrial consultancy and professional qualification in the consultant's proposed area of specialisation. State Bank of India
What Should a Good TEV Report Tell the Lender?
A useful TEV report should ultimately enable a lender to understand:
Is the technology appropriate?
Can the plant realistically achieve its proposed capacity?
Is the CAPEX adequate?
Are the major operating costs credible?
Are utilities sufficient?
Can environmental obligations be met?
Is the implementation schedule realistic?
What technical risks could affect the project's performance?
And most importantly:
Are the technical assumptions supporting the financing model credible?
That is the central purpose of lender-side techno-economic evaluation.

Frequently Asked Questions
What is the full form of TEV report?
TEV stands for Techno Economic Viability. A TEV report examines whether a project is technically feasible and whether its engineering assumptions support its proposed economics.
Why do banks ask for a TEV report?
Banks may use TEV reports to independently assess technology, production capacity, machinery, CAPEX, operating costs, utilities, implementation and project risks before making or modifying financing decisions.
Is a TEV report compulsory for every bank loan?
No. Whether a TEV study is required depends on the lender, size and nature of the financing, project complexity and technical risk.
Is TEV the same as a DPR?
No. A DPR describes the proposed project and its assumptions. A TEV study independently examines whether those assumptions are technically and economically reasonable.
Does a TEV consultant verify plant capacity?
Capacity review is frequently an important component of TEV. It may consider equipment capacity, process sequence, utilities, operating hours and bottlenecks rather than relying only on nominal design capacity.
Does a TEV report include CAPEX verification?
A TEV assignment may review whether major project-cost components are technically reasonable and whether important equipment, utilities, environmental systems, installation and supporting infrastructure have been adequately considered.
Can TEV be carried out for an existing factory?
Yes. Technical evaluation may be used in connection with expansion, refinancing, restructuring, acquisition or additional funding for an existing facility.
Can a TEV study identify environmental risks?
Yes. Depending on scope, it may examine environmental approvals, water requirements, wastewater treatment, pollution-control infrastructure and other compliance-linked technical issues.
