# DOR Technology

## Meet DOR.

A compact 200 kW on-site power generation unit designed to run on multiple fuels, adapt to your demand, and grow with your business.

- **Fuel flexibility:** Designed to run on natural gas, CNG, LPG, biofuel and hydrogen blends, subject to validation, certification and site configuration.
- **Power that follows demand:** Planned controls coordinate output as your site’s needs change.
- **Room to grow:** Designed to add capacity with more DOR units as your business grows.

The DOR (Distributed On-demand Resource) is a distributed on-site power platform in development. This reference provides the technical detail behind the concise [Technology page](/technology/). An integrated DOR prototype has not yet been built or tested; first pilots are planned for 2027. Figures are engineering targets; Power OS functions and operating modes are planned capabilities.

## Core engineering targets

| Parameter | Target |
|---|---|
| Rated electrical output | 200 kW per unit |
| Package dimensions | 1.4 m × 1.0 m × 2.0 m (length × width × height) |
| System weight | 700 kg |
| Electrical response | Sub-ms (<1 ms) |

## Further engineering targets

| Parameter | Target and basis |
|---|---|
| Mechanical input | Approximately 230 kW |
| Engine thermal efficiency | 42%; BSFC optimum of 185 g/kWh at 2,200–3,200 RPM |
| Engine-to-grid conversion | 87% |
| Full-system fuel-to-electrical efficiency at variable load | Approximately 36.5% (42% × 87%) |
| Equipment footprint | Approximately 15 ft² (1.4 m²); installation clearances are additional |
| Power density | Approximately 90 kVA/m³ |
| Acoustics | 69 dBA at 5 m |
| Engine package | Six-cylinder direct-injection architecture; 780 × 500 × 900 mm and 200 kg |
| Major service interval | 10,000 operating hours planning target; final intervals depend on testing and the operating profile |

Full-system efficiency describes fuel-to-electrical conversion at variable load, not the percentage of rated load the system can support. These targets do not establish a measured efficiency curve or guaranteed operating load range.

### Response functions

| Function | Engineering target |
|---|---|
| Electrical response | Sub-ms (<1 ms) |
| Engine startup/ramp to full output | Under 5 seconds |
| Grid-to-island transfer | Under 50 ms; dependent on site-specific electrical design |

These are separate functions. None establishes validated black-start capability or seamless transfer. See the [structured specification](/technology/datasheet.json) for current target definitions.

## Planned fuel configurations

The multi-fuel design is being developed around natural gas, compressed natural gas (CNG), LPG, biofuel, and hydrogen blends. CNG is a compressed form of natural gas. Specific biofuel types and hydrogen-blend proportions are not established by this list. Fuel selection, switching, emissions, and hardware configuration depend on validation, certification, market, and site requirements.

## Architecture and operating modes

The design combines a direct-injection engine, electrical generation, a grid-forming inverter, and Power OS. Planned operating modes are standalone, grid-tied, and microgrid. Multi-unit paralleling, load sharing, redundancy, and Power OS coordination remain planned capabilities.

The planned site roles are:

- **Add capacity:** Supply local power alongside an existing grid connection.
- **Manage peaks:** Vary local output against a site-specific grid-import limit.
- **Support continuity:** Supply selected loads in a properly engineered islanded configuration.

The homepage’s edge data center example illustrates 400 kW from the grid plus 600 kW from three planned DOR units targeting 200 kW each, for 1 MW of total site supply including compute, cooling and supporting loads. Grid-only mode shows 400 kW; island mode shows 600 kW for selected loads. These are illustrative sums of engineering targets, not a site-sizing recommendation. Actual capacity, reserves, protection and load selection depend on site engineering and validation. The illustration does not establish seamless transfer, full-site backup, or redundancy at every load.

Bosch ECU/component use is a planned configuration subject to final supplier selection. It does not establish a signed supply agreement.

## Power OS: planned functions

Power OS is the software layer being developed for a single DOR or a fleet. The functions below describe intended behavior, not a currently operating customer system.

- **Monitoring and fault detection:** Monitor unit-health signals, fuel level, temperature, and service conditions; identify deviations for operator review.
- **Demand analysis and forecasting:** Use consumption history, weather, and site schedules to support dispatch and capacity planning.
- **Peak shaving:** Coordinate on-site generation against an agreed grid-import limit. Savings depend on the actual tariff, load profile, fuel, and validated system behavior.
- **Grid and islanded operation:** Coordinate planned grid-tied and standalone configurations, subject to protection design, electrical integration, and validation.
- **Fleet coordination:** Support planned load sharing, unit-health review, and dispatch across multiple units.
- **EPC and service planning:** Help operators and installation partners identify future capacity needs, plan service visits, and prepare replacement parts from operating information.

The service program and authorized service network have not yet been established. Final monitoring, maintenance, and commercial support scope remain under development.

## Illustrative economics

At a natural-gas price of $4/MMBtu and the 36.5% fuel-to-electrical efficiency target, illustrative fuel-only electricity cost is approximately $0.037/kWh:

`$4 ÷ (293.07 kWh/MMBtu × 0.365) ≈ $0.037/kWh`

This excludes equipment, maintenance, financing, permitting, interconnection, taxes, and site work. It is a planning example, not a quote or validated operating cost. Maintenance planning uses approximately $10,000/year per unit at 8 hours/day; actual intervals and costs depend on testing and the operating profile.

Deployment timing depends on site engineering, structural support, fuel access, permitting, electrical integration, and construction. Equipment footprint does not include installation clearances or supporting infrastructure.

\* The DOR is in development. Specifications, capabilities, fuel configurations and service offerings are targets or planned features, subject to validation and applicable certification. First pilots are planned for 2027. Images are illustrative.
