Adding a battery behind your plant's connection? Ingro EMS-RE runs it: energy the plant would otherwise curtail is stored, delivered in the hours it is worth most, and used to hold the plant to its schedule. Your power plant controller stays in charge of the connection point. We work with it, not instead of it.
Solar parks, wind farms and hybrid plants are adding batteries behind the same connection. The battery needs a controller of its own, and the plant already has one at the connection point.
On a clear or windy day the plant can produce more than it is allowed to export. Above the limit, output is held back and the energy is lost.
Midday solar is plentiful; the evening peak is where each unit is worth most. A battery moves energy from one to the other only if something decides, every cycle, when to charge and when to discharge.
It decides when the battery charges and discharges. The EMS reads the plant's output, the export limit, the schedule and the battery's own limits on every cycle, then stores energy that would otherwise be curtailed, delivers it in the hours it is worth most, and smooths the plant's output so it holds its schedule.
Ingro EMS-RE is an energy management system for battery storage co-located with a solar or wind plant. It decides when the battery charges and discharges: storing energy the plant would otherwise curtail, delivering it in the hours it is worth most and holding the plant to its schedule. It works with the plant's existing power plant controller (PPC) and does not replace it.

Solar or wind plant + co-located battery · works with your PPC
The battery is rarely the weak point. The decisions behind it are.
A battery charged on a fixed timetable is often full, or empty, at the wrong moment, and the plant curtails anyway.
Cloud and wind change output minute to minute. Without storage scheduled against the commitment, deviations follow.
The PPC holds the connection point. A battery controller that ignores it ends up working against it, so the two have to be coordinated by design.
Cycling hard for every small gain shortens battery life. Each cycle has to stay inside the limits that protect the warranty.
Pick a moment. The parts lit green are working; the PPC holds the connection point throughout.
As output rises, the battery smooths the ramp so the plant follows its schedule rather than the sky.
Ingro EMS-RE is added beside the plant controller you already have. Nothing at the connection point is replaced.
How control is split between the PPC and the EMS is agreed at design for each plant: the EMS can follow battery set-points from the PPC, or schedule the battery and give the PPC its available power.
The EMS works from the plant's metered output, its export limit and its schedule, so the same controller runs storage at a solar park, a wind farm or a hybrid of the two.
A running plant with curtailment above its export limit and an evening peak it cannot serve.

EMS-GS: grid-scale storageSolar or wind plant + co-located battery · works with your PPC. Integration is confirmed against your equipment list during discovery.
Active and reactive power, ramp rates and export limits at the point of connection. At a solar or wind plant Ingro EMS works with the PPC already there and runs the battery behind it; on standalone storage, Ingro EMS-GS is the plant controller.
Cell limits, state of charge and state of health read every cycle, and the power conversion system dispatched inside them.
The incoming revenue meter and sub-meters on feeders, tenants and large loads, read every cycle, so control and the bill work from the same numbers.
Any make that accepts a remote active-power limit, over Modbus or SunSpec, so solar is held back only when it has to be.
Dispatch instructions executed and deviations recorded in the operator's format and timing.
Process and equipment signals over Modbus, OPC-UA or IEC 61850, so the EMS sees what the plant is doing; data goes back to your SCADA over REST or WebSocket.
Ingro scopes, models, commissions and supports the system, or supplies the EMS to the EPC building yours.
What exists, what has been ordered, and the outcomes the plant is required to deliver. One schedule and one conversation.
Written against those outcomes, so that the plant is capable of what has been asked of it.
Your asset counts, loads, tariff and load profile are run against a full simulation of the site before equipment ships, including adverse conditions. Behaviour is reviewed and revised at this stage.
Wired, configured and tested against the site's own values, with the results recorded.
Personnel trained, the reporting suite in service, and a defined route for support thereafter.

It decides when the battery charges and discharges. The EMS reads the plant's output, the export limit, the schedule and the battery's own limits on every cycle, then stores energy that would otherwise be curtailed, delivers it in the hours it is worth most, and smooths the plant's output so it holds its schedule.
Yes. The battery is connected alongside the existing plant, and Ingro EMS-RE is integrated with the PPC and SCADA already there over the interfaces they support, such as Modbus TCP, IEC 61850, DNP3 or OPC-UA. Compatibility is confirmed against your equipment list during discovery.
Yes. The EMS works from the plant's metered output, its export limit and its schedule, so the same controller runs storage at a solar park, a wind farm or a hybrid of the two.
Storage health and warranty, availability and cycles, and deviations against the schedule, issued monthly for owners and lenders. Where the plant's generation data is shared with the EMS, the Solar Generation Performance report (structured to IEC 61724-1) is issued alongside.
No. The plant's PPC keeps control of the inverters, the export limit and grid-code compliance at the connection point. Ingro EMS-RE runs the co-located battery and works with the PPC. The split of control is agreed at design for each plant: the EMS can follow battery setpoints from the PPC, or schedule the battery and give the PPC its available power.
Yes. Those are renewable plants with storage that must deliver to a committed profile, and the battery is scheduled against that profile with every deviation recorded. Requirements differ by tender and by agreement, so we scope against the document itself.
EMS-GS is for standalone storage at a substation, where Ingro EMS-GS is the plant controller. EMS-RE is for storage that shares a connection with a solar or wind plant, where the plant's own PPC stays in charge and the EMS runs the battery.

Send us your site, hardware and tariff or tender, and an engineer will answer it.
Send the plant's single-line diagram, the PPC and SCADA make, and the export limit or schedule you deliver against. We will scope EMS-RE around what is already there.
