Utility-Scale Battery Storage Systems
Grid-connected LiFePO4 battery energy storage systems (BESS) engineered for utilities, IPPs, and renewable developers — scalable from megawatt-hours to gigawatt-hours.
Grid-Scale Storage Built on LiFePO4
Utility-scale battery storage is the backbone of a modern, renewable-heavy grid. ChargeX designs and manufactures utility-scale battery energy storage systems (BESS) that store energy when generation is abundant and dispatch it when demand peaks — smoothing solar and wind output, deferring transmission upgrades, and delivering fast-response grid services.
Every system is built on lithium iron phosphate (LiFePO4) cells, the safest and most durable mainstream lithium chemistry for stationary storage. With 6,000+ full cycles, minimal calendar degradation, and a thermally stable cathode, LiFePO4 drives down the levelized cost of storage across a 15–20 year project life.
From a single containerized unit to a multi-hundred-megawatt-hour installation, ChargeX platforms scale modularly. Integrated battery management, active thermal management, and multi-layer fire detection and suppression are engineered in — not bolted on — so your project clears interconnection and permitting with confidence.
A useful RFQ includes MW/MWh targets, duration, interconnect voltage, and the fire-code path (UL 9540 / NFPA 855 as applicable). Legacy /grid-scale-energy-storage URLs permanently redirect here so one canonical page owns the intent cluster.
We quote landed cost ranges from project drawings — not invented star ratings. Ask for CAGE 93CZ2, DUNS 109774429, and UN38.3 transport docs when your procurement packet requires them.

Where Utility-Scale Storage Delivers
Frequently Asked Questions
What is utility-scale battery storage?
Utility-scale battery storage refers to large battery energy storage systems (BESS), typically rated in megawatt-hours (MWh), that connect directly to the electric grid or a large generation asset. These systems store energy from solar, wind, or the grid and dispatch it to balance supply and demand, provide frequency regulation, and firm up renewable generation.
How much does utility-scale battery storage cost per kWh?
Installed costs for utility-scale lithium battery storage generally range from roughly $200 to $400 per kWh depending on system size, duration, site conditions, and interconnection requirements. LiFePO4 chemistry lowers lifetime cost through 6,000+ cycle life and minimal degradation, which reduces the levelized cost of storage. Contact our engineering team for a project-specific quote.
What battery chemistry does ChargeX use for utility-scale projects?
We build utility-scale systems on lithium iron phosphate (LiFePO4) cells. LiFePO4 offers the safest thermal profile of mainstream lithium chemistries, an extremely stable cathode, 6,000+ cycles at 80% depth of discharge, and a wide operating temperature range — making it the preferred chemistry for stationary grid storage.
Can the system integrate with solar and wind farms?
Yes. Our BESS platforms are designed for DC- or AC-coupled integration with utility solar farms and wind sites, supporting renewable smoothing, energy time-shifting, curtailment capture, and grid-forming inverter operation.
What safety and compliance standards are supported?
Systems are engineered to UL 9540 / UL 9540A, UL 1973, NFPA 855, and IEEE 1547 interconnection requirements, with integrated battery management, thermal management, and multi-layer fire detection and suppression.
Scope Your Utility-Scale Project
Share your MW/MWh targets, duration, and interconnection requirements — our engineering team will size a LiFePO4 BESS and provide a project-specific cost-per-kWh quote.
Utility-scale storage is a plant spec
A webpage cannot size a substation battery. Duration, point of interconnection, and the grid service you are actually selling (energy, capacity, or a named ancillary product) decide the equipment. Chemistry is downstream of that.
Duration and the service
Two-hour and four-hour plants are different amounts of cells in front of the same inverter family only if the inverter and the site were designed that way. State the megawatt and megawatt-hour targets, or state the load and the hours. One of those has to be real.
Frequency response, capacity, and backup are different control problems. Name the one in the interconnection or the offtake. We will not relabel a catalog rack as all three.
Site constraints that move the quote
Ambient, elevation, fire code, and available fault current show up before cell brochures. A container that cannot reject heat will derate until the duration you sold no longer exists.
Augmentation — adding duration later — only works if the inverter, transformer, and pad were planned for it. Say whether this is a full plant or a DC block inside someone else’s PCS.
A merged URL you may still have bookmarked
Grid-scale and utility-scale were the same intent. /grid-scale-energy-storage permanently redirects here so the plant conversation has one address.
ChargeX manufactures in the US. Transport paperwork is UN38.3. Government bids can cite CAGE 93CZ2 and DUNS 109774429. Other listings (UL, IEC, a MIL-STD dash number) are per SKU — ask and we send the PDF we have.
Questions we get on this use case
Do you publish a turnkey $/kWh on this page?
No. Interconnection, duration, and code make that number site-specific. Ask for a quote with MW, MWh, and location.
Is a commercial building peak-shaving job this page?
No. Behind-the-meter peak shaving for a facility is the peak-shaving page. This page is utility and grid-scale plant scope.
Who signs the interconnection?
The project owner and the utility. We supply equipment to the spec. We do not become the interconnecting customer by writing a product page.
