Grid connection limit control
Power limiting based on configured import/export limits, load prioritization and prevention of reserved capacity exceedances.
Energy • Energy Management • EMS/SCADA
Energy management that turns technologies into a system.
EMS/SCADA is the system “brain”: it supervises grid limits, enforces zero export, optimizes self-consumption and makes data useful through monitoring & reporting. Without control, PV is just generation, BESS is just a battery, and EV charging is just another load.
- ✓ power control & limits
- ✓ zero export / export limiting
- ✓ consumption, peak shaving, alarms
- ✓ reporting for operations / ESG
We design the system within agreed operational limits, with emphasis on safety, documentation and a verifiable handover.

What we deliver with EMS/SCADA
We focus on results that work in real operations—and that you can prove with data, tests and documentation.
Zero export and controlled export
Controlling generation and consumption so export stays within agreed limits. Practical for sites where export is not desired.
Consumption optimization
Logic to use on-site generation efficiently: load shifting, control of heating/technologies, schedules and targets aligned with operations.
BESS control & peak shaving
Battery charge/discharge based on limits, price signals and operational priorities. Foundation for peak shaving and demand stabilization.
EV charging load management
Control of charging power so EV charging stays within site limits and makes sense alongside PV generation and BESS.
Monitoring & reporting
Dashboards, notifications, deviation analysis and exports for operational reporting (and ESG reporting when needed).
How EMS/SCADA works
The principle is simple: we measure the system state, evaluate rules and targets, and control sources and loads. What matters is correct metering, safe control and verified logic.
- Metering: utility meters, power quality meters, PV/BESS power readings, status signals from technologies.
- Control logic: grid limits, zero export, load priorities, schedules and operational modes.
- Integration: connection to switchboards, PLC/control, data networks and supervisory systems.
- Supervision: alarms, history, dashboards, reporting and continuous tuning.
What we solve in practice
On paper everything looks easy. In real operations, the details of metering, limits, load interactions and fail-safe behavior decide the outcome.
Operate within limits—predictably
Stable behavior during PV/load fluctuations, clear priorities, and defined rules for abnormal states.
Measurable economics
Self-consumption, peak shaving and battery modes designed from your data—not a generic template.
Ready for the next step
With data and control logic in place, expansions become simpler (more PV, larger BESS, additional charging) and technical preparation for flexibility aggregation is straightforward.
How cooperation works
A short, robust approach that stays grounded in technical reality: data → design → implementation → verification → supervision.
1) Analysis & goals
We review consumption data, site limits and technologies, then define the control goals together.
2) Control logic design
We define rules and modes, design metering and integrations, and produce a clear specification.
3) Integration & testing
Implementation of control, communications and alarms. Scenario testing including limits and exceptions.
4) Handover & supervision
Documentation, training and reporting. Optional service supervision and continuous tuning.

Frequently asked questions
What is EMS (Energy Management System) and why use it on-site?
EMS is a system for controlling and optimizing energy in a facility. It collects consumption and generation data, evaluates them and controls technologies (PV, BESS, EV charging, CHP, controllable loads) to keep grid limits, reduce costs and increase self-consumption of on-site generation.
What’s the difference between EMS, BMS (MaR/BMS) and SCADA?
BMS typically controls building systems (HVAC, lighting), while SCADA provides supervision and control of technological systems. EMS is energy-focused: it optimizes power flows, priorities and the operational economics across technologies, often integrating with BMS/SCADA and metering.
What savings can we realistically expect from EMS?
It depends on your load profile, tariff structure, peak demand and the technology mix. EMS most often helps reduce demand peaks, increase PV self-consumption and improve operational planning. We quantify the benefit after analyzing your data (typically 15-minute measurements) and defining scenarios.
Can EMS help avoid exceeding reserved capacity and penalties?
Yes. EMS supervises the grid connection limit and controls loads by priority (e.g., charging, compressors, HVAC, production technologies) to prevent exceedances. The design includes ramps, blocks, fail-safe modes and logic for critical states.
Can you integrate EMS with PV (FVE) and a battery (BESS)?
Yes—this is the most common combination. EMS plans and controls BESS charging/discharging based on PV generation, site consumption and site limits. The goal is higher self-consumption, stabilized demand and meaningful battery operation within agreed operational limits.
How does EMS control EV charging (load management)?
EMS can dynamically control charging power according to current site consumption and available capacity. With PV/BESS, it can prioritize charging during surpluses, distribute power across charge points and keep charging within defined limits without impacting critical technologies.
Is EMS useful even without PV and a battery?
Yes. EMS can deliver value purely through consumption control: peak shaving, load prioritization, operational planning and monitoring. If you later add PV/BESS, EMS can extend naturally without major architecture changes.
What data and metering do you need to design EMS?
Ideally 15-minute consumption data (at least several weeks, preferably 3–12 months), information about the grid connection and contractual limits, and a list of main technologies/loads and their modes. We also need access to main feeder metering and optionally sub-metering for key circuits so the optimization reflects reality.
How does EMS integrate with existing systems (BMS/SCADA/meters)?
We start with a technical audit and a signal map. Then we design integrations (commonly Modbus TCP/RTU, BACnet, OPC UA, MQTT or APIs depending on technologies), set up data collection, alarms and control logic. The handover includes testing, data validation, documentation and training.
Do you provide monitoring, reporting and long-term EMS support?
Yes. We implement supervision, alarms, dashboards and regular reporting (consumption, peaks, PV generation, BESS utilization, control interventions). We provide service support and configuration maintenance to keep data quality and expected benefits over time.
