Commercial generator fuel consumption depends on generator size, load, engine, efficiency, and operating conditions. To estimate what your facility needs, take the manufacturer’s fuel-consumption data at your expected load, multiply the hourly burn rate by the runtime you need, and add up every generator that will run. Then compare the total with the fuel you…

A generator fuel contract sets pricing terms, delivery expectations, and emergency procedures before you need fuel. Emergency spot delivery is a one-time order placed when the need is urgent. Contracts generally suit facilities with recurring generator demand or critical backup power. Spot delivery suits occasional or unexpected needs. Neither is right for every business.  The…

Multi-site generator fuel delivery is coordinated diesel refueling across several facilities, based on each site’s fuel level, consumption, and delivery requirements. Businesses keep generators ready through central scheduling, site-specific fuel plans, and emergency refueling arrangements set up before the outage, not during it.  Keeping one generator fueled is manageable. Keeping generators ready across several facilities…

DIY generator refueling gives your business direct control over fuel purchasing and refueling schedules, but you supply the staff, the equipment, and the transportation. Hiring a fuel provider takes internal handling off your list and supports planned deliveries, but you take on delivery fees, supplier scheduling, and site access requirements. The right answer depends on…

To hire a generator fuel provider, start by writing down your generator’s fuel needs, tank capacity, and delivery requirements. Compare suppliers on coverage, delivery capacity, total cost, emergency availability, and contract terms. Before you sign, confirm that the supplier can reach your site, test it with a trial delivery, and agree on a fuel supply…

A generator day tank is a smaller tank near the generator that feeds fuel to the engine. A main tank is the larger storage tank that holds the bulk of the fuel. For many commercial generator systems, the generator day tank vs main tank question is not an either-or decision. The main tank stores the…

A generator with a 200, 500, or 1,000-gallon tank does not tell you how long the lights stay on. Tank size is one input. The other two are how fast the generator burns fuel and how much load it carries. Generator runtime = usable fuel ÷ fuel consumption per hour. This guide walks through the…
