// The Role of Generators in DER

Not Just Backup — Generators as Active DER Assets

Most facilities think of generators as emergency equipment sitting idle in a parking lot. AMRENERGY takes a fundamentally different approach: generators are active components of your distributed energy resource strategy — coordinated by our DERMS platform alongside solar, battery storage, and fuel cells to deliver power at the optimal cost at all times

When used as prime or continuous power assets — particularly natural gas generators in facilities with high, consistent baseload demand — generators can produce electricity below utility rates, especially in markets with expensive peak tariffs. When paired with battery storage and solar, the generator fills gaps that intermittent renewables cannot cover, ensuring your facility always has power regardless of weather, grid conditions, or utility outages.

AMRENERGY handles generator selection, sourcing, engineering, permitting, installation, load bank testing, commissioning, and ongoing O&M — fully integrated with the rest of your DER system under a single contract.

We Integrate the Right Generator for Your Application

AMRENERGY works across all major commercial generator technologies, selecting the right fuel type, capacity, and configuration based on your facility’s load profile, fuel supply infrastructure, emissions requirements, and resilience objectives.

Natural Gas
Natural Gas Generators

The most cost-effective fuel for continuous and prime power applications where a gas utility connection exists. Lower fuel cost than diesel, cleaner emissions, no on-site fuel storage required..

Ideal for prime and continuous power CHP heat recovery integration available Lower NOx vs diesel when optimized Scalable from 50kW to multi-MW

Diesel
Diesel Generators

The proven choice for standby and emergency power. Fast start, high power density, and no dependency on gas utility infrastructure make diesel the most widely deployed C&I standby technology..

Best for standby and emergency duty Fast cold-start capability (<10 seconds) No utility gas connection required Broad capacity range and wide availability

Dual-Fuel
Dual-Fuel Generators

Dual-fuel generators operate on a diesel and natural gas blend, reducing diesel consumption and emissions while maintaining fast-start reliability — a flexible choice for facilities balancing cost and resilience..

Reduced diesel fuel consumption Lower operating cost in prime mode Diesel fallback if gas supply interrupts Reduced carbon footprint vs. diesel-only

Hydrogen-Ready
Hydrogen-Compatible Generators

AMRENERGY can specify generator sets capable of operating on hydrogen blends or 100% green hydrogen — future-proofing your generation asset for a low-carbon fuel supply as hydrogen availability grows. .

Future-proof toward zero-carbon fuel Blended H2/natural gas operation Compatible with AMRENERGY DERMS Available in select configurations now

// Generator Operating Modes

Three Ways Generators Work in Your DER System

AMRENERGY configures generators for the operating mode that delivers the most value in your facility’s specific energy context — and our DERMS platform coordinates dispatch automatically.

01

Standby Power

The generator sits offline and starts automatically within seconds when a grid outage is detected. DERMS-coordinated automatic transfer switching manages the transition, keeping critical loads powered without interruption.

02

Prime Power

The generator runs as a primary power source during specific windows — peak demand periods, grid price spikes, or planned outages — dispatched by DERMS when running it is cheaper than drawing peak-rate utility power.

03

Continuous Baseload

In locations with limited or unreliable grid access, the generator operates continuously as the primary source, coordinated with solar and storage for maximum fuel efficiency and lowest overall cost of electricity.

How Your Generator Connects to the Full DER Ecosystem

Every AMRENERGY generator installation connects to our DERMS platform via MODBus protocol. The controller monitors generator status, fuel consumption, load share, and equipment health in real time — dispatching or shutting down the unit automatically based on energy prices, grid conditions, and your facility’s demand profile.

Facilities That Depend on AMRENERGY Generator Integration

Hospitals & Healthcare

Life safety loads require immediate backup power. AMRENERGY sizes and coordinates generator capacity to NEC Article 517 healthcare requirements with automatic transfer switching and DERMS monitoring.

Data Centers & Critical IT

Millisecond-sensitive loads require coordinated generator, battery, and UPS systems. AMRENERGY's DERMS orchestrates the handoff from battery to generator during extended outages.

Manufacturing & Industrial

Process downtime costs far outweigh generator operating costs. Natural gas prime power generators reduce peak utility bills while ensuring production continuity around the clock.

Retail & Grocery

Refrigeration and food safety require standby power. AMRENERGY integrates diesel standby with DERMS load shedding to prioritize critical refrigeration during outages.

Remote & Off-Grid Sites

Agricultural operations, mining sites, and remote facilities use natural gas or diesel generators as primary power in AMRENERGY hybrid DER configurations with solar and battery storage.

Multi-Tenant & Mixed-Use

Campus microgrids with distributed generator assets provide shared standby power across multiple buildings, coordinated by AMRENERGY's central DERMS controller.

// FAQ

Common Questions About Commercial Generator Integration

Can AMRENERGY integrate an existing generator into a new DER system?

In many cases, yes. AMRENERGY’s engineering team will assess your existing generator’s capacity, control interface, and condition to determine whether it can be integrated into a DERMS-coordinated DER system. If the generator communicates via MODBus or supports standard control interfaces, integration is typically feasible. An assessment will confirm compatibility and identify any required control upgrades.

What is the difference between standby, prime, and continuous generator ratings?

Standby rating is for emergency use only — typically up to 200 hours per year at variable load. Prime rating allows unlimited operating hours at variable load with a defined peak overload capacity. Continuous rating is for constant load applications with no overload. AMRENERGY selects the appropriate rating class based on your facility’s intended use of the generator.

How does a generator integrate with battery storage?

In AMRENERGY DER configurations, batteries handle short-duration load spikes and provide bridge power during the 10–20 seconds it takes a generator to start and reach operating speed. Once the generator is online, it takes over the primary load while the battery recharges. AMRENERGY’s DERMS coordinates this handoff automatically, eliminating manual operation.

What permits are required for a commercial generator installation?

Commercial generator installations typically require building permits, electrical permits, air quality permits for larger units, and potentially fire department approval for fuel storage. AMRENERGY manages all permitting as part of the turnkey EPC process — you don’t navigate the regulatory process independently.

Does AMRENERGY provide ongoing maintenance for generators?

Yes. AMRENERGY’s O&M program covers generator preventive maintenance, load bank testing, fuel system inspection, and remote monitoring via DERMS. Regular maintenance is critical for reliability — a generator that hasn’t been tested will not start reliably during an actual emergency.
