Built Around Your Power Requirement

Battery Energy Storage Systems (BESS)

Prismecs designs, integrates, and deploys mobile battery energy storage systems engineered around your site's load profile, operating strategy, and deployment requirements. Factory-tested in Odessa, Texas, each system supports grid support, diesel displacement, or hybrid generation, delivering storage that works the way your project demands.

The System Behind the Storage

Prismecs' BESS packages are built around key integrated subsystems, each engineered to work as part of a deployable, field-ready power asset. This is not just a battery bolted onto a trailer, but a complete system designed for demanding industrial applications and duty cycles.

Built to Fit Your Power Strategy

From managing peak demand to reducing generator runtime, BESS can take on different roles across your power system, helping you operate more efficiently, reliably, and cost-effectively.

Peak shaving battery storage reduces demand charges by discharging stored energy during load spikes, helping facilities manage peak consumption without expanding grid or generation capacity.

Grid support battery storage delivers fast voltage regulation, frequency response, and reactive power, strengthening grid stability where capacity is limited or electrical conditions fluctuate.

Energy shifting battery storage stores electricity during lower-cost periods and dispatches it during higher-demand periods, helping commercial and industrial BESS reduce energy costs.

BESS can reduce generator runtime, fuel use, and emissions when integrated with on-site generation or grid supply, providing reliable power for demanding remote and industrial operations.

A hybrid generator battery system works alongside generators or renewables, improving fuel efficiency, smoothing load changes, and allowing generation assets to operate more effectively.

Temporary battery power for construction sites provides flexible electricity where permanent infrastructure is unavailable or delayed, with trailer-mounted BESS enabling rapid deployment across changing locations.

Battery energy storage as a service provides contracted storage capacity without full ownership, helping businesses reduce upfront costs while maintaining flexible access to BESS capacity.

How We Deliver BESS for Your Power Needs

Prismecs starts with the power requirement, not the product catalog. Every BESS project follows an engineering-driven process that accounts for load, site, operations, and deployment before equipment selection begins.

Why Prismecs Packaged Power

Our engineering approach comes from packaging high-pressure rotating equipment in the Permian Basin. We apply that same discipline to every project.

Why Prismecs Packaged Power
  • Field-Proven Heritage

    Our engineering discipline comes from packaging gas turbines for demanding, continuous-duty environments. We apply that same process to every BESS system.

  • OEM-Agnostic Integration

    We select and integrate equipment around your project requirements, working across manufacturers rather than designing from a single supplier or technology.

  • Mobile by Design

    Transportability is considered from the first design stage, with system dimensions, road logistics, site access, and rapid connection built into the plan.

  • Full-Spectrum Integration

    We engineer storage, generation, electrical infrastructure, controls, and packaging as one coordinated system, not as separate components assembled in isolation.

  • Factory-Tested Before It Ships

    Every system undergoes factory acceptance testing, including electrical load testing, BMS/PCS/EMS functional checks, controls verification, protection testing, and system integration checks, at our Odessa facility before shipment to the site.

  • Designed for U.S. Compliance

    Every package is designed to meet applicable U.S. safety, electrical, fire protection, and transportation requirements as part of the standard engineering scope.

Frequently Asked Questions

A mobile battery energy storage system is designed for transport and rapid deployment. Unlike fixed systems, it can be delivered where power is needed without permanent installation. Trailer-mounted BESS solutions can support temporary, remote, or constrained-grid projects where speed and flexibility are important.

PCS, or Power Conversion System, manages the conversion of electricity between the battery and the AC electrical system. It controls how energy is charged and discharged, helping BESS respond to load and grid requirements while maintaining reliable system operation.

To determine how to size a battery energy storage system, we review your load profile, peak demand, operating strategy, required power rating, energy capacity, and discharge duration. Site conditions and intended use, such as peak-shaving battery storage or energy-shifting battery storage, also influence the final system design.

Pricing varies with system capacity, power requirements, equipment, controls, and site conditions. Leasing can make sense for temporary or short-term needs, while purchasing may be more suitable for long-term projects with consistent energy storage requirements.

Service life depends on factors such as cycling frequency, operating temperature, depth of discharge, charge and discharge rates, and system management. Proper operation and maintenance can help preserve battery performance and extend the system’s useful service life.

BESS projects must meet applicable safety requirements based on system design, installation, and local regulations. Fire protection measures are incorporated according to project requirements to help manage thermal and electrical risks throughout system operation.

BESS can support black start when designed with the required PCS, controls, and battery capacity. This capability depends on the system architecture, generator configuration, and specific project requirements.
