A PESO License for Diesel Storage in India may be required when a factory, hospital, data centre, warehouse, construction project, commercial facility, or other business plans to store diesel in bulk for DG sets, machinery, or captive use.

PESO - the Petroleum and Explosives Safety Organisation - regulates petroleum storage and associated safety requirements in India. Whether a licence is required depends on the quantity of diesel, tank capacity, installation type, location, and intended use.

For businesses, the most important point is to check compliance before purchasing or installing the tank. An unsuitable location or incorrect storage configuration can later require expensive modifications.

Green Permits Consulting supports businesses with PESO applicability assessment, diesel storage licence applications, technical documentation, site-layout planning, and regulatory coordination.

What is a PESO License for Diesel Storage?

A PESO licence is an approval associated with the storage and handling of petroleum products where the proposed installation falls within the applicable regulatory framework.

Although diesel is widely used in industrial facilities, bulk storage still needs to be planned safely.

The normal project flow is:

Diesel Requirement → Storage Capacity → Site Selection → PESO Assessment → Application → Installation

The exact requirement should be determined from the actual tank and facility configuration.

Who May Need a Diesel Storage License?

PESO compliance may need to be assessed by manufacturing plants, hospitals, hotels, warehouses, data centres, construction projects, infrastructure companies, mining operations, logistics facilities, and commercial buildings using diesel in significant quantities.

A small operational storage arrangement may have different requirements from a large industrial bulk tank. Therefore, the proposed capacity and use should be reviewed before deciding the licensing route.

PESO License for Diesel Storage for DG Sets

DG sets are one of the most common reasons businesses maintain diesel storage.

Factories, hospitals, and data centres may need a reliable reserve to keep essential operations running during power failures.

A typical arrangement can be:

Bulk Diesel Tank → Transfer System → Day Tank → DG Set

The storage capacity should be based on actual consumption, backup requirement, and fuel delivery frequency rather than selecting an unnecessarily large tank.

Above-Ground and Underground Diesel Tanks

Diesel can be stored in above-ground or underground tanks depending on the site and operational requirement.

Above-ground tanks are easier to inspect and maintain but require suitable containment, access, and separation from surrounding structures.

Underground tanks can save surface space but require proper civil work, leak protection, venting, and maintenance access.

The correct option should be selected during project planning.

How to Decide Diesel Storage Capacity

Tank capacity should be calculated from expected diesel consumption.

For example, if a facility consumes 1,000 litres per day during generator operation, the business should decide how many days of fuel reserve it actually needs.

The basic planning logic is:

Daily Consumption × Required Backup Days + Operational Buffer

This helps avoid both under-sizing and unnecessary over-capacity.

Site Selection for Diesel Storage

Tank location is a critical part of the project.

The proposed area should be reviewed in relation to factory buildings, plot boundaries, electrical installations, access roads, ignition sources, and other storage areas.

Fuel tanker access should also be considered so that filling can take place safely without disturbing normal operations.

Selecting the correct location before construction can save considerable time and cost later.

Safety Distance and Layout Planning

There is no single safety distance that applies to every diesel storage project.

The required arrangement depends on factors such as storage quantity, tank type, site configuration, and surrounding structures.

The technical layout should therefore be prepared specifically for the project and should show the storage tank, nearby buildings, boundaries, filling point, venting arrangement, and access.

The actual installation should match the approved design.

Spill and Leakage Control

Diesel leakage can create fire and environmental risks.

Suitable containment should therefore be incorporated into the storage system, especially for above-ground installations.

The project should also consider safe drainage, spill response, emergency procedures, and proper maintenance.

These controls are important for both regulatory compliance and day-to-day operations.

PESO License Application Process

The application process generally starts with an assessment of the storage requirement and tank configuration.

Once the capacity and site are finalised, technical drawings and supporting documents are prepared. The application is then filed through the applicable PESO process.

The basic sequence is:

Applicability Check → Capacity Finalisation → Layout → Documentation → Application → Installation / Inspection → Licence

The exact steps depend on the type of installation.

Documents Required for PESO Diesel Storage License

The document requirement varies by project, but applications commonly involve company details, land ownership or lease documents, tank specifications, site layout, authorised signatory information, and technical drawings.

Additional NOCs or related approvals may also be required depending on the facility.

The checklist should therefore be prepared after understanding the proposed storage system.

PESO License and Fire NOC

A PESO licence and Fire NOC are different approvals.

PESO focuses on petroleum storage and related safety requirements, while the fire authority evaluates fire-prevention and emergency arrangements.

Depending on the project, both approvals may need to be assessed.

Similarly, Pollution Control Board approvals such as CTE or CTO do not automatically replace PESO requirements.

Diesel Storage for Manufacturing Plants

Manufacturing industries often maintain diesel for backup DG sets and other approved operational uses.

For a new factory, diesel storage should ideally be included in the original plant layout so that tanker access, containment, safety separation, and other requirements can be planned properly.

Adding a bulk tank after the plant is fully constructed can make compliance more difficult.

Diesel Storage for Hospitals and Data Centres

Hospitals and data centres require reliable backup power and may therefore store significant quantities of diesel.

Because these facilities contain critical equipment and occupied areas, careful tank location, emergency planning, and safe access are especially important.

The storage system should be designed around both operational continuity and regulatory safety.

Modification of Existing Diesel Storage

Existing facilities should review compliance before increasing tank capacity or changing the storage location.

For example, increasing storage from 10 KL to 30 KL can change the regulatory and layout requirements.

Likewise, shifting an existing tank to another area of the premises may affect safety considerations.

Major modifications should therefore be assessed before installation.

Common Mistakes in Diesel Storage Projects

A common mistake is ordering the tank before checking the site and regulatory requirement.

Another is submitting one capacity or location in the application and installing something different on site.

Businesses may also forget to coordinate PESO requirements with fire, environmental, or factory approvals.

A better sequence is:

Requirement → Capacity → Site → Regulatory Assessment → Approval → Installation

Why Hire a PESO Consultant?

A PESO consultant helps businesses understand whether licensing applies, review the proposed tank arrangement, prepare documents and drawings, and support the application process.

This is especially useful for new industrial projects because compliance can be built into the layout before civil work starts.
