Plant Equipment & Tank Sizing

A cooking gas plant is, at its core, a bulk LPG storage tank connected to a metered filling point. Everything else exists to move gas safely from a road bridger or coastal terminal into the household and commercial cylinders your customers bring back. Get the tank size and the filling hardware right and the rest of the build is straightforward; get them wrong and you either stall on capacity or sink capital you cannot recover.

The hardware list below is what a working mini-to-mid plant actually needs before it can pass inspection and take its first delivery. Tank capacity is quoted in metric tonnes (MT) because that is how bulk LPG is bought and sold.

Core equipment list

• Bulk LPG storage tank (1.5–10 MT): the foundation of the plant. A 1.5–2.5 MT tank suits a residential refilling start; 5–10 MT serves bulk resellers. In Nigeria, a 1.5 MT tank with a foreign-made dispenser starts around NGN 9.24M and a 2.5 MT around NGN 11.6M.
• Decanting pump & vapour-recovery line: transfers liquid LPG from the tank into cylinders and recovers vapour to cut losses.
• Electronic filling scale: meters each cylinder by weight (3kg, 6kg, 12.5kg, 50kg) so you charge accurately and avoid overfilling.
• Dispenser unit: the customer-facing fill point. Premium "Cleantech"-grade units raise cost but reduce wastage and speed up turnaround.
• Fire safety kit: extinguishers, fire sand buckets, safety signage, water sprinkler/deluge points. In Nigeria this kit runs NGN 200K–1M and is non-negotiable for commissioning.
• Cylinder float (exchange model only): a stock of branded cylinders if you run an exchange rather than refill-on-the-spot. This is working capital that ties up cash.
• Weighbridge or platform scale (larger plants): for verifying bulk deliveries against your purchase invoice.
• ATEX/PESO-rated electrical fittings: any electrics in the gas zone must be certified for a flammable atmosphere.

The most useful planning number here is not the tank price; it is the relationship between tank size and daily throughput. A tank that holds two days of peak demand lets you ride out a late bulk delivery. A tank that holds half a day forces you to refuse customers the moment a bridger is delayed. Your business plan should state the target daily fill volume in kilograms first, then size the tank to it, not the other way round.

What It Costs to Build a Plant

Startup capital for a cooking gas plant swings widely with tank capacity, land cost and how automated the filling line is. The figures below are grounded in current operator-reported numbers across the three markets where this business is most active.

Nigerian cost data is drawn from current plant-equipment pricing (NaijaLPG, 2025); Indian project-cost ranges from filling-plant project profiles (Khatabook, 2025).

Where the money actually goes

• Bulk storage tank: the single largest line, typically 30–45% of capital. The jump from 2.5 MT to 10 MT is where most of the spread comes from.
• Land or plant lease and civil works: a plant usually needs 1–2 acres because mandatory setback distances dictate the footprint. Buying land in India can be ₹30–70 lakh on its own.
• Dispenser, scale and decanting pump: roughly NGN 200K–1M in Nigeria; more for automated, multi-bay lines.
• Licensing and regulatory compliance: NGN 1M–3M in Nigeria for permit fees and inspections.
• Fire safety system: NGN 200K–1M, required before the plant can be commissioned.
• Working capital: first bulk gas purchase, staff wages and, for an exchange model, the cylinder float.

Funding routes

In the US, an SBA 7(a) loan covers up to $5M over terms as long as 25 years and is the most common route for capital-intensive fuel and energy retail builds; our bespoke service formats financials to lender expectations. In the UK, the government-backed Start Up Loans scheme offers up to £25,000 per founder at 6% fixed with free mentoring — useful for a smaller cylinder-distribution arm rather than a full plant. In Nigeria, the Bank of Industry (BOI) and commercial term loans are the usual sources, and lenders almost always demand a throughput-based financial model before releasing funds. A plan that shows kilograms filled per day, blended margin and breakeven month is what gets the facility approved.

Where to Source Gas & Hardware

Your supply chain has two halves: the molecules (bulk LPG you buy and resell) and the metal (tanks, dispensers, cylinders). New operators tend to obsess over the plant build and underthink the gas-supply relationship, which is the part that determines whether you ever run dry.

Bulk LPG offtake and terminals

In Nigeria, the realistic options are buying from a coastal terminal or a large marketer with depot capacity. Named operators with terminal or depot scale include Nipco Gas (an 11,000 MT depot and around 39 stations), Rain Oil (an 8,000 MT depot, 40 LPG trucks and an ocean-going vessel), Techno Gas (an 8,000 MT coastal terminal plus a cylinder-manufacturing plant), Nidogas (one of the oldest marketers, incorporated 1955) and Banner Gas (reputed to run the largest network of cooking gas plants and building a 13,000 MT terminal in Akwa Ibom). In India, retail supply ties back to Indane, Bharat Gas, HP Gas and private players like Reliance Gas and SuperGas. In the UK, Calor and Flogas dominate cylinder supply.

Plant hardware and cylinders

• Storage tanks & skids: sourced from LPG equipment fabricators; Cleantech-grade dispensers are the premium reference point in Nigerian pricing.
• Cylinder supply: for an exchange model, source compliant 3kg, 6kg and 12.5kg cylinders; Techno Gas, for example, runs a multi-million-unit annual cylinder plant.
• Filling scales & safety valves: buy certified hardware only — uncertified electricals will fail a PESO or fire-service inspection.
• Transport bridgers: if you self-collect bulk gas, a road bridger (or a contracted haulier) connects the terminal to your tank.

Negotiate gas supply on landing cost, not headline price. The gap between your landing cost per kilogram and your retail price is your entire business, so a small per-kg discount on a reliable, consistent supplier beats a cheaper but erratic one every time.

Permits & Safety Compliance

LPG is a regulated dangerous substance everywhere it is sold, so this is the section that most often delays a launch. The agencies, documents and lead times differ by country, but the principle is identical: you cannot accept or fill gas until the regulator and the fire authority have signed off.

Nigeria

• Apply for an NMDPRA (formerly DPR) LPG plant permit via the official portal at lpgplant.nmdpra.gov.ng.
• Submit a company profile: registered name, business type, contact address, year of incorporation, Tax Identification Number and director details.
• Pass site inspection against setback and safety standards.
• Obtain a fire service certificate and meet state environmental requirements.

India

• Obtain a PESO licence (Petroleum and Explosives Safety Organisation) under the Gas Cylinders Rules 2016 and SMPV (Unfired) Rules 2016.
• File Form C for filling/storing compressed gas, with business registration, identity and site-ownership proof.
• Provide a site layout drawn to scale, storage-capacity details and technical drawings of the LPG system.
• Submit a HAZOP or risk-analysis report and fire-safety arrangements; electrical apparatus needs Chief Controller of Explosives approval.

United States

• Comply with NFPA 58 (Liquefied Petroleum Gas Code) for design, installation and operation.
• Prepare a written Fire Safety Analysis — required for installations over 4,000 gallons aggregate capacity — plus operations and maintenance instructions.
• Hold a state LP-Gas licence: the Railroad Commission of Texas, the South Carolina LP Gas Board and Florida's FDACS all license LPG manufacture, storage, distribution and transport.

United Kingdom

• Carry out a DSEAR risk assessment (Dangerous Substances and Explosive Atmospheres Regulations 2002) — mandatory for LPG storage.
• Comply with the Pressure Systems Safety Regulations 2000 for pressurised vessels.
• Use ATEX-certified electrical equipment in the flammable zone (HSE guidance).
• Follow Liquid Gas UK Code of Practice 7 on storing full and empty cylinders; quantities over 50kg trigger defined separation distances or firewall protection.

Compliance detail is summarised from HSE, NFPA 58 and Nigeria's NMDPRA permit guidance. Build at least three to six months of permitting lead time into your launch schedule.

Margins & the Throughput Maths

Most guides on this business stop at "it's profitable." The number that actually drives a cooking gas plant is the spread between your landing cost per kilogram and your sell price per kilogram, multiplied by the kilograms you move per day. Everything else is overhead against that.

In Nigeria, local refilling stations commonly earn NGN 100–410 per kg, with NGN 100–310/kg typical after costs. A simple, real-world illustration: buy at NGN 890/kg and sell at NGN 1,200/kg and you make NGN 310/kg, which is roughly NGN 1.55 million on a single 5,000 kg truck (KiakiaGas). In India, filling-plant margins run INR 30–80 per cylinder, and a plant filling 3,000–5,000 cylinders a day can gross INR 1–2.5 lakh daily.

A worked throughput example

Take a 20 MT plant in Ibadan, Oyo State. Operator data puts the landing cost of a 12.5kg refill at about NGN 1,931, an average retail price of NGN 2,610 and a bulk price to resellers of NGN 2,150 (NIG LP Gas). If that plant fills 5,000 kg a day at a blended margin of NGN 200/kg, that is NGN 1,000,000 in gross margin per day, or roughly NGN 26M a month before rent, wages, transport, evaporation losses and compliance. After those costs, plant-level net margins usually settle in the 5–12% band — thinner than retail but on much larger volumes.

The strongest plans do not chase one stream. They blend a high-margin retail line with steady bulk volume so the plant runs near capacity even when walk-in demand dips, which is exactly what keeps the storage tank turning over fast enough to justify its cost.

Market Size & Demand

The global liquefied petroleum gas market was valued at roughly $162.98 billion in 2025 and is projected to reach $273.24 billion by 2034 at a 6.46% CAGR (Fortune Business Insights, 2025). Other trackers place 2025 nearer $191 billion heading toward $277 billion by 2035 (Market Research Future, 2025). Either way, the direction is clear and the demand sits squarely in the cooking-and-heating segment a local plant serves.

Demand is structural, not faddish. More than 280 million households worldwide use LPG as their primary cooking and heating fuel, and Asia Pacific alone holds a 48.34% share, driven by clean-fuel transition programmes pulling households off wood, charcoal and kerosene (Global Growth Insights, 2025). For a plant operator, that translates into a customer base that refills on a predictable cycle rather than buying once.

The competitive reality on the ground is that big marketers own the terminals while thousands of independent plants own the last mile. A new operator does not compete with Nipco or Indane on scale; it competes on proximity, reliability and not running out of gas on a Friday evening. That is a positioning point your plan should make explicit.

Who Actually Buys From a Gas Plant

A cooking gas plant rarely serves a single buyer. The plants that run near capacity are the ones that have deliberately built three or four distinct customer lines, each refilling on its own rhythm. Mapping these segments precisely is what separates a plan a lender takes seriously from a vague "everyone needs gas" pitch.

• Walk-in households: the volume base. They arrive with a 3kg, 6kg or 12.5kg cylinder and refill on a roughly two-to-four-week cycle. Convenience and queue speed decide where they go, so location and turnaround time matter more than price for this group.
• Independent "gas points" and small retailers: resellers who buy bulk from your plant and sell on in smaller quantities to their own neighbourhoods. They take steady, predictable volume at a thinner per-kilogram margin and effectively extend your reach without you funding more sites.
• Commercial kitchens and food vendors: restaurants, bakeries, hotels and street-food operators who burn gas daily and value a reliable supply contract over a marginal saving. These accounts justify a delivery service and command premium pricing.
• Light industrial users: small manufacturers, welders and processors who use LPG as a process fuel. Lower in number but high in per-account value and contractually sticky once you have proven reliability.

The discipline your business plan should impose is to quantify each segment: how many households live within your catchment, how many gas points already operate nearby, how much a typical commercial account consumes per month. Vague demand assertions get a plan rejected; a plant that says "4,200 households and 14 food vendors within 3km, refilling on a 21-day cycle" gets read. The template includes a customer-analysis section built to force exactly this level of specificity.

Segment economics also differ in ways that shape your build. Household walk-ins give you the fattest per-kilogram margin but are weather- and payday-sensitive. Bulk resellers smooth your throughput so the storage tank turns over fast enough to earn its keep. Commercial contracts give you a forecastable baseline you can show a bank. The right mix is rarely all of one; it is a deliberate blend that keeps the plant busy across the week.

Running the Plant Day to Day

Once the tank is installed and the permit is granted, the business becomes an operations discipline: take delivery of bulk gas, fill cylinders safely and accurately, and never let either supply or safety lapse. The operations section of your plan is where a lender or regulator looks to see whether you have actually thought through how the plant runs, not just what it costs.

The core daily workflow

• Bulk intake: receive LPG from a road bridger or terminal, verify the quantity against the invoice (weighbridge or calibrated meter) and log it. Discrepancies between purchased and received kilograms quietly erode margin if no one checks.
• Filling: decant from the bulk tank into customer cylinders by weight on a calibrated scale, never by eye. Overfilling is dangerous and illegal; underfilling loses customers.
• Safety checks: inspect cylinders for damage and valve integrity before filling, and run the standing fire-safety routine — extinguishers charged, signage clear, no ignition sources in the zone.
• Stock and reorder: track tank level against your reorder point so the next bulk delivery lands before you run dry. This is the single operational habit that most determines whether the plant ever turns customers away.

Staffing a small plant

A mini plant can run with a lean team: a plant manager responsible for safety and supply, two or three trained filling attendants, a security presence and, if you deliver, a driver. The non-negotiable is that everyone handling gas is trained on safe filling and emergency response. Lenders and regulators both expect to see named, qualified people in the management section — "we will hire trained staff" is far weaker than naming a plant manager with downstream fuel or LPG experience. Wage costs are modest relative to the gas spend, but a single safety incident can close the plant, so training is not a place to economise.

Supply reliability is the whole game

Because your entire margin lives in the gap between landing cost and sell price, the supply relationship is strategic, not transactional. The strongest plans secure at least an understanding (and ideally a contract) with a terminal or large marketer before commissioning, and they model what happens to cash flow if landing cost rises sharply — as LPG prices do. An operator who has war-gamed a price spike and a delayed delivery, and shown how the plant absorbs both, reads as someone a bank can lend to.

Getting Customers Through the Gate

Demand for cooking gas is structural, but a new plant still has to win it away from the plant down the road. Marketing an LPG plant is mostly local, practical and trust-based rather than a matter of clever advertising.

• Visibility and signage: a clearly branded, easy-to-enter site on a road households already travel captures walk-in volume that no online campaign will. Location does most of the marketing work.
• Reliability as the message: "always in stock, accurate fills, safe site" is the positioning that actually converts in this category. A plant known for never running dry on a busy evening earns repeat custom that price cuts cannot buy.
• Reseller recruitment: signing up nearby gas points and small retailers as bulk customers is a faster route to volume than chasing households one at a time. Treat resellers as partners with reliable supply and fair bulk pricing.
• Commercial outreach: direct contact with restaurants, bakeries and food vendors to win supply contracts gives you the forecastable baseline that stabilises the whole operation.
• Delivery and cylinder exchange: a doorstep refill or full-for-empty exchange service differentiates you from a plain refill point and supports premium pricing, especially for commercial accounts.
• Local digital presence: a simple listing on local maps and directories, plus a phone number people can call to check stock, captures the growing share of customers who search before they drive.

The marketing section of your business plan should tie each of these tactics to a customer segment and a cost, then to the throughput target that makes the whole model work. Marketing that is not connected back to kilograms filled per day is just spending; marketing that fills the tank's daily capacity is what the financials assume.

Mistakes That Sink New Plants

The failures in this business are rarely about demand — gas sells. They are about siting, sizing and cash. These are the five that most often turn a promising plant into a stalled one.

• Signing the lease before checking setbacks. NFPA 58 in the US and NMDPRA standards in Nigeria impose minimum separation distances. Operators who lease first and check later discover the site can never be approved, and the deposit is gone.
• Under-sizing the storage tank. A tank that holds half a day of demand forces you to turn customers away every time a bulk delivery is late. Size to peak throughput plus a buffer.
• Forgetting cylinder-float capital. An exchange model needs a stock of branded cylinders in circulation. New owners model the plant but not the float, then run short of working capital in month two.
• Pricing straight off landing cost. Decanting and evaporation losses, transport and idle-tank financing all eat the spread. A NGN 310/kg headline margin is not NGN 310/kg of profit.
• Commissioning before inspection. Accepting gas before the fire service and regulator sign off invites a shutdown order and reputational damage that is hard to undo.

More Operator Questions

How big a storage tank do I need for a mini gas plant?

Most mini plants begin with a 1.5–2.5 MT tank, which comfortably handles low-volume residential refilling. Plants targeting bulk resellers usually step up to 5 or 10 MT. Always size against your projected peak daily throughput in kilograms, with a buffer for delayed deliveries.

How long does it take to get an LPG plant permit?

It depends on jurisdiction and how complete your application is. Nigerian NMDPRA approval hinges on site inspection and fire-service certification; PESO licensing in India and US state LP-Gas licensing both turn on a site layout and safety review. Plan for three to six months and never accept gas before approval is confirmed.

Can I run a cooking gas business without building a full plant?

Yes. Many operators start as a retail "gas point" — buying bulk from a nearby plant and refilling small cylinders — before investing in their own storage tank. It is lower capital and a sensible way to learn the demand pattern in your area before committing to a plant build. The business plan template covers both models.

What insurance does a cooking gas plant need?

At minimum, public liability and product liability cover, plus property and fire cover on the tank and premises. In the UK, employers' liability is a legal requirement once you hire staff. Lenders and regulators will both expect to see proof of adequate cover before they engage.
