Put your site’s energy to work.
Coordinate solar generation and storage around your operating profile, energy costs and critical loads.
Three common starting points.
The assessment decides which one applies — and whether storage is the right answer at all.
Peak demand
Shift load away from the billing peak and hold the demand window below an agreed threshold.
Power quality and ride-through
Support voltage-sensitive processes through dips and short interruptions, within a defined operating envelope.
Capacity and expansion
Defer or avoid an upstream upgrade by adding storage at the constrained point, where the site supports it.
We assess first, then specify.
Share your load data, tariff, electrical arrangement and project objectives. We will tell you what can be quoted and what needs a site assessment.
Assess
Interval load data, tariff, single-line diagram, protection settings and project objectives.
Design
System size, duration, protection coordination and interfaces against the site’s actual operating conditions.
Validate
Approved configurations only. Ratings and protection settings checked against product evidence.
Deliver
Scope table, installation responsibilities, commissioning checklist and support.
A proposal built around your site.
Savings and resilience depend on configuration, operating conditions and the agreed scope. We assess first, then specify.

No savings figure is guaranteed before a contract and a defined operating period are in place.
Savings only hold if the system is sized to the duty it actually runs.
The capacity range follows from what the storage has to do, not from the price list. Three common duties, and the checks we run behind each one before a return figure is quoted.
| Duty | Capacity range | Typical application |
|---|---|---|
| Peak shaving | 100 kWh – 1 MWh | Manufacturing and logistics parks with a pronounced demand peak. Cabinetised, low-voltage connection, controlled from interval metering data. |
| Power quality and backup | 200 kWh – 2 MWh | Sites where one power-quality event stops production. Storage carries demand management plus dip and interruption ride-through. |
| Containerised storage | 1 MWh and above | Larger industrial sites and parks, typically medium-voltage connection with multiple load centres. |
- 15-minute demand window
- Rack balancing and circulating current
- Cooling matched to climate and duty
- Transformer and protection overload limits
Cooling selection includes temperature uniformity, pump and coolant maintenance, and local service capability.
| Capacity range | kWh to MWh scale (per project) |
| Enclosure | Cabinetised / containerised |
| Cooling | Air or liquid cooled (per project) |
| Grid connection | Low-voltage, optional MV integration |

Why commercial storage projects stall
Commercial and industrial storage has a stronger business case than residential storage — the loads are larger, the tariffs are more complex, and the savings are easier to quantify. It also has a longer list of ways to fail.
Most C&I projects do not fail because the battery was wrong. They fail in the space between disciplines: the electrical study that was never done properly, the protection settings nobody coordinated, the load profile that was estimated rather than measured, and the commissioning that revealed all three at once.
There is a pattern in how these projects are sold. The savings are modelled from the tariff schedule, a published document, rather than from the site's metered behaviour, which is not published and not always collected. A tariff-based model always produces a clean number. Whether that number survives contact with the real load profile is a separate question, and it is usually answered after the equipment has been ordered.
This page sets out where the risk actually sits in a C&I project, and how an integrated supply scope reduces it.

Where C&I projects actually go wrong
Peak demand determines both the value of the system and the sizing of every component behind it. When the profile comes from a utility bill and a guess, the resulting design is optimised for a site that does not exist. We ask for interval meter data before sizing anything.
Adding storage to an existing low-voltage installation changes fault levels and may require changes to upstream protection. If this is not analysed at design stage, it surfaces during commissioning — at which point the fix is expensive and the schedule is already lost.
Who supplies the switchgear? Who configures the EMS? Who signs off the grid connection application? On a project with three or four suppliers, every boundary is a place where responsibility can be dropped. On a single-scope project, there is nowhere for it to be dropped.
Our approach
We start from the site's actual load profile, fault level, and existing protection arrangement. The equipment list follows the study, not the other way round.
Battery systems, PCS, and low-voltage switchgear come from a single supplier under a single warranty. This removes the most common boundary failure in C&I projects.
Where third-party equipment is involved — existing transformers, generators, building management systems — we document the interface explicitly: protocol, data points, responsibility for configuration.
A commissioning checklist is prepared during design, not written on site. Issues found during the checklist are engineering problems; issues found after handover are warranty claims.
Typical configurations
Manufacturing and logistics sites with a pronounced demand peak. Cabinetised, connected at low voltage, controlled against the site's interval meter data.
Sites where power quality events cause production losses. Storage provides both demand management and ride-through against voltage dips and short interruptions.
Larger industrial sites and campus installations, often with medium-voltage connection and multiple load centres.
Technical read: four things that quietly break a C&I business case
A fifteen-minute demand window means the controller's objective is to hold the average below a threshold across the whole window, not to clip the tallest spike. Systems tuned to clip instantaneous peaks underperform on demand charge reduction, and the error stays invisible until the first utility bill arrives.
Where several clusters sit on a common DC bus, small differences in internal resistance or state of charge produce circulating current that does not appear in the total power figure. Cluster-level management and per-cluster current limiting are what keep the array balanced; without them, the weakest cluster sets the life of the whole system.
Air cooling is simpler and cheaper, but struggles to hold a tight temperature spread across a large pack in a hot climate. Liquid cooling holds cell-to-cell spread closer, at the cost of pumps, coolant circuits, and a maintenance item that field staff must be trained for. The choice should follow the duty cycle and the ambient condition, not the price list.
A converter that can carry one hundred and ten percent for ten seconds is useful only if the upstream transformer and protection can accommodate that current without tripping. Where the two are procured separately, the overload figure is often quoted by one supplier and quietly invalidated by the other.
Integration considerations
In most markets the connection application requires electrical drawings, protection settings, and sometimes a grid study. This is a schedule-critical path and should start early.
Where the site already has discrimination settings in place, adding storage may require re-coordination. We map the existing arrangement before proposing a design.
Enclosure placement, separation distances, and detection requirements are determined by local code and by the system's chemistry and capacity. We confirm requirements for your jurisdiction rather than assuming.
A C&I system needs to be operable by the site's own staff. We specify what the operator will see and act on, and what escalates to us.
