Energy Storage at Scale: The Right Chemistry for the Right Application

Advanced battery technologies engineered for grid services, renewable firming, and mission-critical backup—from proven lithium to next-generation sodium and solid-state.

Storage as Core Infrastructure

Energy storage is no longer a future technology—it's the enabling infrastructure that makes renewable integration, grid stability, and data centre resilience possible today. NUE deploys utility-scale battery energy storage systems (BESS) using the most advanced, bankable, and application-appropriate chemistries available.

Why Battery Storage Matters

Grid-Scale Value Creation

  • Firm intermittent renewable generation (solar, wind)
  • Provide frequency regulation and voltage support
  • Enable peak shaving and load shifting
  • Capture arbitrage opportunities (charge low, discharge high)
  • Deliver black-start capability and grid resilience

Behind-the-Meter Value

  • Reduce demand charges for industrial and data centre loads
  • Provide N+1 backup for mission-critical operations
  • Smooth renewable self-consumption
  • Participate in demand response programs

Three Battery Chemistries, Three Strategic Applications

At NUE, we don't believe in one-size-fits-all. Different use cases demand different battery technologies.

Lithium Iron Phosphate (LFP)

The Proven Workhorse

Chemistry: Lithium Iron Phosphate (LiFePO₄)

Why LFP

Safety First

Thermal stability superior to NMC/NCA chemistries; lower fire risk

Cycle Life

6,000–10,000 cycles at 80% depth of discharge

Cost Competitive

Lower upfront cost than solid-state; higher cycle life than NMC

Proven at Scale

Deployed globally by utilities, data centres, and industrial users

Bankable

Mature supply chain, established warranty terms, insurable

LFP Limitations

  • Lower energy density than NMC (requires more space)
  • Performance degradation in extreme cold (requires thermal management)

NUE LFP Deployments

NUE Battery Storage Investment Thesis

Chemistry Diversification = Risk Mitigation

By deploying multiple chemistries, we:

De-Risk Supply Chains

Not dependent on a single lithium supply

Optimize Economics

Match cheapest, safest chemistry to each use case

Capture Innovation Upside

Early position in sodium and solid-state as costs decline

Build Institutional Relationships

Partner with manufacturers, utilities, and offtakers across technology platforms

Revenue Stacking for BESS

Battery storage isn't a single revenue stream—it's a platform for multiple value captures.

Capacity Payments

Contracted availability payments from grid operators

Energy Arbitrage

Buy low (off-peak), sell high (peak)

Ancillary Services

Frequency regulation, voltage support, reactive power

Renewable Firming

Enable solar/wind to meet firm capacity requirements

Demand Charge Reduction

Behind-the-meter savings for industrial/data centre loads

Black-Start Services

Grid restoration capability after outages

Battery storage is the connective tissue between intermittent renewables, firm dispatchable power, and grid reliability. NUE's multi-chemistry approach positions us to deploy the safest, most bankable, and most cost-effective storage solution for each application—today and tomorrow.
