Division 02
Solar generates when the sun is up. Your load does not care. Storage closes that gap — shifting energy to the hours it is worth the most, and holding the grid steady in between.
Why storage, why now
Lithium cell prices have fallen far enough that storage now pays for itself on demand charges alone for many industrial consumers — before you count a single unit of solar shifted from afternoon to evening.
At the same time, regulators are moving toward round-the-clock and firm renewable supply. A solar plant without storage can only bid into part of that market. With storage, it can bid into all of it.
Applications
The battery covers your highest half-hour peaks so your sanctioned demand — and the demand charge billed against it — comes down. Often the fastest payback of any storage use case.
Store the midday surplus and release it through the evening peak, when tariffs are highest. Turns a daytime asset into a dispatchable one.
Seamless changeover for process lines, cold storage, data and medical loads — without the fuel, noise and maintenance of a diesel set.
Firm and RTC tenders require supply through the night. Storage is what makes a solar portfolio eligible to bid.
Charge on the off-peak tariff, discharge on the peak. Where ToD slabs are wide, the spread alone carries the project.
Ramp-rate control and voltage support at the point of connection, smoothing the output a DISCOM sees from a variable plant.
How we work
We start with your actual interval data — half-hourly consumption, demand peaks, tariff structure and existing generation. Battery sizing that ignores the load curve is guesswork.
Power rating and energy capacity are two separate decisions. We model both against the saving they actually unlock, and tell you where the curve flattens and more capacity stops paying.
Cell chemistry, battery management, power conversion, thermal management, fire detection and suppression — specified to the site, not to a standard datasheet.
Existing solar, DG sets, captive generation and the grid connection all have to cooperate. The controls layer is where storage projects succeed or disappoint.
CEIG clearance, DISCOM interconnection, metering and any storage-specific conditions in the state regulations — handled as part of the scope.
Round-trip efficiency and state of health degrade over time. We monitor both and report against the business case the system was sold on.
A battery is not a product you buy, it is a decision about when your energy is worth the most. Get the load curve right and the hardware almost specifies itself.
Auctus Resources — storage practiceStart a conversation
A rooftop plant, a MW-scale open access project, a storage system to cut demand charges, or a forecasting model for an asset you already own — we will tell you plainly whether it works, what it costs, and how long it takes.
