Building a Gas Plant Next Door and Signing a Twenty Year Contract
Industrial gas companies often build plants beside a single customer and sign long contracts that guarantee payment regardless of usage. The arrangement turns a commodity into a stable, annuity like business.
Turning a Commodity Into an Annuity
Industrial gases, oxygen, nitrogen, hydrogen and others, are commodities used in vast quantities by industries from steel to chemicals to electronics. Selling a commodity would normally be a low margin, competitive business. Yet industrial gas companies earn stable, attractive returns, because of how they structure their largest supply arrangements.
For big customers, the gas company often builds a production plant right next to the customer facility, dedicated to serving it, and signs a long term contract that guarantees payment regardless of how much gas the customer actually uses. This structure transforms a commodity into something closer to an annuity, a stable, long lived, predictable stream of revenue.
A commodity sold on the open market earns thin margins. The same commodity supplied through a plant built beside one customer on a twenty year contract earns stable, protected returns. The structure is the business.
The On Site Model
The largest arrangements use an on site plant: the gas company builds and operates a facility adjacent to a large customer, often connected directly by pipeline, producing gas specifically for that customer.
| Feature | Effect |
|---|---|
| Plant built beside customer | Dedicated, integrated supply |
| Long term contract | 15 to 20 years, locked in |
| Take or pay terms | Customer pays regardless of usage |
| Cost pass through | Energy costs passed to customer |
The contracts are long, often fifteen to twenty years, and structured to protect the gas company return. The key term is take or pay: the customer commits to pay for a minimum amount whether or not it uses the gas, which guarantees the gas company revenue even if the customer production falls. Energy, the main input cost, is often passed through to the customer, protecting the gas company margin from energy price swings. These terms remove much of the risk, turning the investment in the plant into a secure, contracted return.
Why the Structure Is So Stable
The on site model with take or pay contracts produces remarkable stability. The gas company invests in the plant knowing it will be paid for years regardless of the customer usage, so the return on the investment is largely locked in from the start, protected against demand fluctuations and input cost swings.
The long contract also creates a durable relationship, since the customer depends on the adjacent plant for essential supply and cannot easily switch, being physically integrated with the gas company facility. This deep integration and the long contract make the revenue extremely sticky, and the take or pay terms make it predictable. The result is an annuity like income stream from each on site arrangement, which is why industrial gas companies, despite selling commodities, earn stable and attractive returns that the raw commodity nature of the product would not suggest.
The Density Advantage
Beyond on site plants, gas companies serve smaller customers through pipelines and by delivering gas in bulk or cylinders, and here density matters, much as it does for other distribution businesses. A company with many customers clustered in an area can serve them efficiently from shared production and distribution, spreading costs and defending the territory.
This local density creates regional advantages, since a company dominant in an area can serve customers there more cheaply than a competitor would from farther away, and the cost of transporting gas limits how far it can economically be delivered. The industry consolidated into a few large players who built dense regional positions, and the combination of on site annuity contracts with big customers and dense efficient networks serving smaller ones gives the leading companies strong, defensible positions in their markets.
The Barriers That Protect It
The business is protected by significant barriers. The on site plants and pipeline networks are expensive, long lived assets that a competitor cannot easily replicate, and the long contracts lock in the largest customers for years. The integration with customers, physically and contractually, makes displacing an incumbent very difficult.
The capital required to build the production and distribution infrastructure, and the long contracts that tie up the best customers, deter new entrants and protect the established players. This is why the industry is concentrated among a few large companies with strong returns, since the combination of capital intensity, long contracts, physical integration, and regional density creates a business that is far more attractive and defensible than selling a commodity would appear to be. The structure, not the product, is what makes it a good business.
The Bottom Line
Industrial gas companies turn commodity gases into stable, annuity like businesses by building plants beside their largest customers and signing long take or pay contracts that guarantee payment regardless of usage, locking in returns and removing much of the risk. Smaller customers are served through dense regional networks where local density creates efficiency and defends territory. The capital intensive assets, long contracts, physical integration with customers, and regional density erect strong barriers that protect the few large players, making the structure of the supply arrangements, rather than the commodity itself, the source of the attractive and defensible returns.
