How to switch your factory from diesel to piped natural gas
Published 7 July 2026 · Gasland Horizon
Switching an industrial facility from diesel to piped natural gas is a structured process, not a leap of faith. Here is what it involves, from first contact to gas flowing at your gate.
Step 1 - Complete the Energy Data Form
The Energy Data Form (EDF) captures your equipment, current fuel consumption and operating pattern. It is the basis for your savings assessment, for sizing your connection, and for sequencing network build-out. Completing it is free and carries no obligation.
Step 2 - Receive your site-specific assessment
Using your verified fuel records, our commercial and technical teams model your likely saving and the connection your site needs. You see the numbers before any commitment.
Step 3 - Execute a Gas Sales and Purchase Agreement
Supply is contracted under a Gas Sales and Purchase Agreement (GSPA). Both NNPC Gas Marketing Limited and Gasland Horizon are named parties to every GSPA, so your supply is anchored by the national gas marketing company.
Step 4 - Equipment: new gas generators or bi-fuel conversion
Depending on your plant, you either install gas-fired generators or convert existing diesel units to run on gas (a bi-fuel conversion). Because the fuel savings are large relative to the equipment cost, this investment typically pays back within months.
Step 5 - Infrastructure and connection
Gasland Horizon finances and builds the pipeline, spur line and Pressure Regulation and Metering Station that bring gas to your gate. This is the part that takes planning, which is why registering demand early matters - priority during network build-out is sequenced by the demand book.
Step 6 - Supply begins
Metered natural gas is delivered continuously and billed in arrears on what you consume. No tankers, no storage, no advance fuel purchases.
What to prepare
- Twelve months of fuel purchase or consumption records, if available
- Installed generator capacity and typical daily run hours
- Details of any process equipment - boilers, furnaces, ovens, kilns
Common questions
How do I switch my factory from diesel to natural gas?
Start with the Energy Data Form, receive a site-specific savings assessment, then execute a Gas Sales and Purchase Agreement before installing or converting your generation equipment and connecting to the network. The full six-step process is set out above.
Is converting to natural gas expensive?
Converting a diesel generator to run on gas, or installing a new gas-fired generator, is usually recovered from fuel savings within months, because the 40 to 55 percent cut in fuel cost is large relative to the equipment cost.
How long does a natural gas conversion take?
Equipment conversion itself can be done in days once gas reaches your site. The bigger driver of timeline is when the distribution network reaches your location, which is why registering demand early through the Energy Data Form matters.
