Storage & Grid / Flexibility

Store, shift, save.

Storage, controls and flexibility turn energy from a fixed cost into a managed — and often revenue-generating — asset.

The approach

Storage is where generation becomes control.

We model your half-hourly profile and tariff exposure to size storage and controls properly, then coordinate specialists to deliver and commission them. Where flexibility markets are open to you, we advise on how to access them and report the result.

We do

Assess, specify, tender, coordinate delivery, verify and report.

We don't

Install, manufacture or sell equipment — so the advice stays independent.

What this pillar covers.

Each capability is specified independently, tendered to vetted specialists and managed by Iter Group to a single programme.

01

Battery storage

Shift generation and grid import to the cheapest and cleanest hours.

  • Lower peak-rate exposure
  • Maximise self-consumption
  • Backup capability
02

Commercial battery storage (BESS)

Larger containerised systems for industrial sites and portfolios.

  • Storage as a revenue asset
  • Capacity-charge avoidance
  • Scalable, modular capacity
03

Microgrid technology

Featured capability. Generation, storage and controls operating as one coordinated system, with the grid as an option rather than a dependency.

  • Resilience against outages
  • Lower peak-cost exposure
  • Measurable decarbonisation
04

Energy Management Systems

The control layer that decides what runs, when, and from which source.

  • Automated optimisation
  • Visibility of every load
  • Data for ESG reporting
05

Demand-Side Response

Get paid to adjust consumption when the network needs it.

  • Flexibility as revenue
  • No loss of core operation
  • Supports network stability
06

Fast Frequency Response

Sub-second grid services from responsive storage assets.

  • Premium service revenues
  • Fully automated dispatch
  • Strengthens asset business case
07

Voltage optimisation

Match supply voltage to what your equipment actually needs.

  • Immediate consumption savings
  • Longer equipment life
  • Rapid payback

Building a lower-carbon future.
