Power that fits
your operation.
Start with your load, operating hours and available space. Then compare fuel supply, storage duration, permitting and service. The right system may combine generation, batteries and the grid.
Where the DOR fits*
DOR is being developed for sites that need additional local, behind-the-meter power in a compact system designed to expand with demand. The design pairs a six-cylinder engine with a grid-forming inverter for on-site generation. Engineering targets: 200 kW per unit, 700 kg, and a 1.4 × 1.0 × 2.0 m package. Installation clearances are additional. Explore the technology.
| Option | How it supplies power | What to evaluate |
|---|---|---|
| Fuel cells | Convert fuel through an electrochemical process. | Fuel specification, operating profile and service. |
| Linear generators | Convert reciprocating motion into electricity. | Fuel supply, installed configuration and controls. |
| Diesel and natural gas generators | Use an engine to drive a generator. | Duty rating, fuel logistics, emissions and maintenance. |
| Combined heat and power (CHP) | Generate electricity and capture usable heat from the same fuel. | Steady heat load, fuel supply, permitting and maintenance. |
| Battery storage | Store electricity for later use. | Power, usable energy and opportunities to recharge. |
| Grid connection | Delivers electricity through the utility network. | Local capacity, connection conditions and required works. |

Bloom Energy · Fuel cells
Bloom’s Energy Server uses solid-oxide fuel cells to convert fuel into electricity without combustion. Compare the proposed system’s fuel requirements, operating profile and service agreement with your site needs. Bloom’s technology overview.
Mainspring · Linear generators
Mainspring uses a low-temperature reaction to move oscillators through copper coils, generating electricity. Its published platform supports several gaseous fuels. Compare the offered fuel specification and complete installed package for your project. Mainspring’s product specifications.
Diesel and natural gas generators · Match the duty rating
Diesel and natural gas generators are sold with standby, prime and continuous ratings under ISO 8528-1. A prime power generator is rated for variable load over unlimited hours, a continuous rating covers constant load, and standby covers emergency hours only. Match the selected model to your operating hours and load profile. The DOR’s duty ratings remain subject to validation. Caterpillar’s generator rating guide.
CHP · Combined heat and power
Combined heat and power (cogeneration) units generate electricity and capture engine or turbine heat for buildings or processes, so they suit sites with a steady heat load. The DOR is designed as an electrical capacity platform; heat recovery is not part of its published specification. US EPA CHP Partnership overview.
Batteries · Power and duration
Batteries can charge from the grid or generation, including renewables. Usable stored energy and the load determine discharge duration; the charging source determines replenishment. Generation and storage can serve complementary roles. EIA’s battery storage overview.
The grid · Understand your connection
Connection timing depends on location, requested capacity and network work. A generation queue statistic is not a buyer’s electricity-supply timeline. Compare your utility’s actual offer with an engineered on-site plan. Grid connection context and original sources.
