Storage Designed Around the Application

Why Choose Long-Duration Energy Storage?

Many facilities need more than a short burst of backup power. Water plants, industrial facilities, remote operations, and critical campuses may need storage capable of shifting energy over several hours, supporting daily demand-management strategies, or maintaining reserve capacity for extended operating events.

AWP evaluates the battery according to the site—not the other way around.

We assess multiple stationary-storage technologies rather than forcing every application into one chemistry. Systems are selected according to power, duration, cycling frequency, safety, available footprint, operating environment, and project economics.

Potential approaches may include aqueous flow, iron-based, zinc-based, sodium-based, lithium-based, and other stationary storage technologies appropriate for the project.

Key Benefits

Extended Duration

Storage can be configured for multi-hour and long-duration operation instead of only short-term backup.

Technology-Agnostic Design

AWP evaluates multiple battery technologies according to the facility’s actual operating requirements.

Safer Siting Options

Certain non-lithium and aqueous technologies may offer advantages for sensitive or densely occupied facilities.

Daily Deep Cycling

Selected systems can support frequent charging and discharging as part of normal facility operations.

Scalable Energy Capacity

Certain storage technologies allow energy duration to be expanded without proportionally increasing power equipment.

Multiple Value Streams

One battery asset may support peak management, energy shifting, resilience, generator optimization, and grid programs.

Chemistry and Technology Selection

The Right Battery Depends on the Job

Battery technologies differ in operating duration, response speed, cycle life, energy density, safety profile, environmental requirements, maintenance needs, and cost structure.

AWP compares those factors against the actual requirements of the project before recommending a system architecture.

Technology availability, suitability, specifications, and project economics are evaluated on a site-specific basis.

The AWP BESS Assessment Process

Step 01

Collect the Data

Review utility bills, interval-load data, operating schedules, critical loads, site plans, and resilience objectives.

Step 02

Model the Opportunity

Analyze power, duration, demand reduction, energy shifting, operating strategy, and potential economic value.

Step 03

Select the Architecture

Compare battery technologies, vendors, controls, footprint, safety, interconnection, and lifecycle requirements.

Step 04

Integrate and Support

Coordinate procurement, construction, commissioning, controls, measurement, maintenance, and long-term optimization.
