RECD price for DG setWhen evaluating, the amount quoted by a supplier is influenced by much more than the RECD equipment itself. The final cost can change according to the DG engine, power range, selected product, exhaust arrangement, installation location, quantity, logistics, warranty and the scope of technical support. This is why two generator owners can request an RECD and receive noticeably different quotations.

CPCB has published a procedure for emission-compliance testing of Retrofit Emission Control Devices (RECDs) for diesel power-generating-set engines up to 800 kW gross mechanical power. The procedure was revised on July 24, 2023. For a 2026 purchase, buyers should evaluate each cost factor separately and verify the latest applicable official requirements before making a compliance-related decision.

A Simple Way to Understand RECD Cost

Think of the final project cost as several layers rather than one product price:

RECD equipment + application-specific engineering + installation + fabrication + logistics + commissioning + warranty/service

Not every project contains every cost, and not every supplier includes the same items in its quotation.

That is the main reason online prices can vary substantially.

1. DG Engine and Power Range

The first factor affecting the quotation is the generator itself.

Suppliers may require:

Engine manufacturer
Engine model
Engine serial number
Gross mechanical power
DG-set rating
Existing exhaust details

Gross mechanical power is particularly important because CPCB's RECD procedure applies to diesel power-generating-set engines up to 800 kW gross mechanical power, while the manufacturer's published RECD applicability can vary according to engine-power range.

A buyer should therefore avoid requesting a final price based only on:

“RECD for 500 kVA DG.”

Provide the engine information as well.

2. Exact RECD Model

The second major factor is the product itself.

Different RECD models may have different:

Product configurations
Technical specifications
Application ranges
Components
Installation requirements
Documentation

Before discussing price, ask for the exact model number and technical datasheet.

Then compare products with equivalent technical scope.

A ₹90,000 quotation for one model should not automatically be compared with a ₹1,10,000 quotation for a different model without first understanding what each offer contains.

3. Product Applicability

The appropriate RECD depends on the generator application.

CPCB's official material includes manufacturer-specific information for RECD applications rather than treating all products as universally interchangeable. Its generator-set resources also provide Type Approval/COP information.

Therefore, the supplier should establish:

Which engine?

Which gross mechanical power?

Which RECD model?

Which documented application?

The cost of the correct product should be evaluated only after this technical matching is established.

4. Certification and Documentation

Documentation can also influence the commercial package.

A supplier may provide:

Technical datasheet
Application information
Relevant certification/test documentation
Installation documentation
Warranty documentation

CPCB's published procedure sets out the framework for RECD emission-compliance testing and type approval.

Buyers should distinguish between the cost of the physical equipment and any separate technical, testing or documentation services included in a supplier's proposal.

Do not assume that an amount mentioned by a seller is an official CPCB fee. Regulatory payments and supplier charges are separate matters and should be verified independently.

5. Exhaust Configuration

The existing exhaust system can have a major effect on installation cost.

The supplier may need information about:

Exhaust-pipe diameter
Flange arrangement
Existing silencer
Pipe bends
Exhaust routing
Mounting points
Available space

CPCB's RECD testing procedure includes exhaust back pressure among the parameters considered in the testing framework.

Therefore, the proposed product and installation arrangement should be evaluated against the existing exhaust system.

A simple exhaust layout may require limited modification, while a complicated layout can increase fabrication and labour costs.

6. Fabrication Requirements

Fabrication is one of the biggest variables between quotations.

Depending on the installation, additional work could involve:

Flanges
Pipe sections
Bends
Mounting supports
Brackets
Structural work
Welding
Site modifications

Ask the supplier whether fabrication is:

Included

or

Quoted separately

A quotation that excludes fabrication may look cheaper until the actual site work is added.

7. Installation Location

The physical location of the DG affects the amount of work required.

For example, installation can become more complicated when:

The DG room has limited access.
The exhaust is routed through a narrow area.
The installation is at significant height.
Existing supports are inadequate.
Equipment movement is restricted.

A site survey can help identify these factors before final pricing.

This is why suppliers may request photographs, dimensions or an on-site inspection before providing a firm installation quotation.

8. Distance From the Supplier

Geography can influence the total cost through:

Freight
Technician travel
Accommodation
Local transportation
Site visits
Warranty service

A supplier located close to the installation site may have lower travel expenses.

However, proximity should not automatically outweigh technical suitability.

Compare the complete project cost and service capability.

9. Quantity Ordered

The number of DG sets can affect commercial pricing.

For multiple generators, a supplier may offer:

Bulk equipment discounts
Combined transportation
Group installation
Consolidated commissioning
Centralized technical support

However, quantity does not automatically mean identical RECD products should be installed on every generator.

Each DG should still be evaluated according to its engine and applicable product range.

10. Number of Installation Sites

Ten RECD systems at one facility can have a different cost structure from ten systems distributed across ten cities.

Multiple locations can increase:

Transportation
Travel
Site surveys
Installation coordination
Warranty visits
Project-management requirements

For multi-site projects, ask for a location-wise commercial proposal.

11. Commissioning Scope

Some suppliers include commissioning in the installation price.

Others charge separately.

Ask exactly what the supplier means by “commissioning.”

The quotation should clarify whether it includes:

Installation verification
Operational checks
Controller checks, where applicable
Documentation
Technician attendance

A detailed commissioning scope makes supplier comparison easier.

12. Warranty Structure

Warranty terms can affect the overall value of an RECD proposal.

Compare:

Warranty duration
Warranty start date
Covered components
Labour coverage
Site visits
Replacement components
Exclusions

For multi-unit projects, ask whether the warranty starts separately for each installed unit or from one common date.

A longer warranty is useful only when its coverage is clearly defined.

13. Service and Maintenance Support

The supplier's service infrastructure can influence long-term expenditure.

Consider:

Technical support
Preventive maintenance
Site visits
Spare parts
Troubleshooting
Warranty assistance

An organization may prefer a supplier with stronger support even when its initial quotation is somewhat higher.

The decision should be based on the expected value of the additional support.

14. Spare-Part Availability

Replacement components can affect lifecycle cost.

Before ordering, ask:

Which components may require replacement?

Are the parts available in India?

What is the expected delivery time?

Are any components covered under warranty?

Who will install replacements?

This information helps buyers estimate ongoing expenditure instead of looking only at the initial purchase amount.

15. Delivery Requirements

Urgent delivery can sometimes increase project cost.

Ask whether the product is:

Ready in stock
Available after production
Available in batches
Subject to a manufacturing lead time

Also confirm whether expedited transportation is available and whether it carries an additional charge.

For non-urgent projects, planned delivery can sometimes provide better commercial flexibility.

16. Commercial Terms

The supplier's payment and commercial structure can affect procurement planning.

Review:

Advance payment
Balance payment
Taxes
Transportation
Delivery terms
Installation payment
Commissioning payment
Warranty conditions

Two suppliers may quote similar total amounts but require very different payment schedules.

Choose commercial terms that suit your procurement process.

17. Taxes and Other Charges

When comparing quotations, verify whether the quoted amount is:

Before tax

or

Tax inclusive

Also check for separately charged:

Freight
Installation
Fabrication
Travel
Loading/unloading
Other applicable charges

Always compare the final payable amount.

18. Cost of RECD Installation Service

RECD installation service for DG setFor buyers requesting an , installation should be treated as a defined project component rather than an informal add-on.

Ask whether the service includes:

Site survey
Exhaust measurement
Fabrication
Installation
Mounting
Commissioning
Technician travel
Installation report

This creates a clear distinction between the equipment cost and the cost of professional site execution.

19. Brand or Manufacturer Can Influence Commercial Positioning

Different manufacturers may adopt different pricing strategies.

However, a higher price should not automatically be interpreted as higher technical quality, and a lower price should not automatically be interpreted as poor quality.

Compare each product using:

Model + Application + Documentation + Installation + Warranty + Service + Total Cost

This is a more reliable approach than comparing company names alone.

20. Market Competition

Obtaining several quotations can improve price transparency.

Ask suppliers to quote against identical information:

Same DG specifications
Same installation scope
Same delivery location
Same quantity
Same commissioning requirements
Same warranty expectations

Then the differences become easier to understand.

A three-way quotation comparison is more useful when every supplier is quoting an equivalent scope.

21. Why a Site Survey Can Improve Cost Accuracy

A preliminary survey gives the supplier better information about the actual job.

It can help determine:

Exact exhaust dimensions
Mounting requirements
Fabrication needs
Access requirements
Technician requirements
Installation duration

The more accurately the supplier understands the site, the lower the likelihood of unexpected installation charges.

22. Avoid Unclear “All-Inclusive” Quotes

“All-inclusive” sounds attractive, but ask what it actually includes.

Request the supplier to list:

Equipment
Accessories
Fabrication
Installation
Transportation
Commissioning
Warranty
Taxes

An itemized “all-inclusive” proposal is much easier to audit than a single unexplained total.

23. Don't Treat Online Prices as Final Market Rates

Online listings can help establish a starting point, but the final price depends on the specific DG application and project scope.

A website price may exclude:

Site-specific fabrication
Installation
Transportation
Commissioning
Taxes
Service

Therefore, use online prices for research, then request a formal DG-specific quotation.

24. Current CPCB Verification

CPCB's official website maintains a Generator Sets section containing Type Approval/COP information.

Its RECD procedure, revised July 24, 2023, provides the technical framework for compliance testing of applicable RECDs for diesel power-generating-set engines up to 800 kW gross mechanical power.

For a 2026 procurement, buyers should verify the latest official CPCB material and any applicable state or site-specific requirements instead of relying on historical supplier claims.

The cost of an RECD should not be used as evidence of compliance. Price and regulatory status are separate questions.

A Practical Final-Cost Formula

For budgeting purposes, consider:

Total Initial Cost

= RECD equipment

accessories
fabrication
installation
transportation
commissioning
applicable taxes/charges

Then separately consider:

Estimated Ownership Cost

= maintenance

spare parts
service visits
other manufacturer-recommended support

This gives procurement teams a more realistic picture of what the project may cost.

Questions to Ask Before Finalizing Your Budget

Before approving an RECD quotation, ask the supplier:

1. Which exact RECD model is included?

2. What engine-power range is it intended for?

3. Which parts of the installation are included?

4. Is exhaust fabrication included?

5. Is transportation included?

6. Is commissioning included?

7. What warranty is provided?

8. What maintenance is expected?

9. What spare parts may be required?

10. What is the final installed project cost?

These answers allow you to build a realistic budget rather than relying on a single equipment figure.

Final Thoughts

RECD price for DG setcomplete project costRECD installation service for DG setThe final cost of an RECD is not determined by the equipment price alone. The real number is the cost of getting the appropriate product installed, commissioned and supported properly for your specific DG application.The is influenced by a combination of technical, physical, commercial and service-related factors. Engine power determines the relevant product range; the RECD model determines the equipment scope; exhaust configuration affects fabrication; location affects logistics; and warranty and service influence long-term cost. The most reliable approach is to collect accurate DG information, identify the exact RECD model, request itemized quotations and compare the . For buyers considering an , make installation a clearly defined part of the procurement scope. Site survey, exhaust fabrication, mounting, installation and commissioning should be listed separately so you can compare suppliers fairly. For 2026 purchasing decisions, verify the latest official CPCB information and any applicable requirements from the relevant State Pollution Control Board, Pollution Control Committee or other competent authority.
