About us
RENERENERGYisaninnovativetechnologycompanyintheenergysector,specializinginsoftwaresolutionsforRenewableEnergySourcesandBatteryEnergyStorageSystems(BESS).
The company develops integrated SCADA systems for photovoltaic plants and Energy Management Systems (EMS) for storage projects, unified in its proprietary NEXUS platform, offering advanced capabilities for monitoring, controlling, and optimizing the operation of energy projects.
Nexus Platform
One platform, from control to the market
Control, architecture, security, and market integration — all under Nexus.
Control & automation
Closed-loop control at the point of interconnection
Closed-loop PID algorithms ensure accurate setpoint tracking at the Point of Interconnection (POI). Each mode follows reference values from the grid operator or aggregator, with configurable ramp rates and droop slopes per grid code.
Power control
Active Power Control
Tracks a reference value. Negative means absorption, positive means injection, with configurable ramp rates.
Reactive Power Control
Reactive setpoint tracking with the same absorption and injection logic for grid-stability services.
Power Factor (cos φ)
Maintains cos φ at the interconnection point by modulating reactive power relative to active.
Ramp Rate Control
Controlled rate of change for power injection and absorption.
Grid support
Frequency Support
Active-frequency droop on the operator's P-F curve. FSM for ±200 mHz, LFSM-O/LFSM-U for larger excursions.
Voltage Control
Reactive droop at the POI following a U–Q characteristic, tunable per grid code.
State of Charge
Manages SoC bands across all plant containers.
Grid-Forming
Grid-forming capabilities for black-start and weak-grid operation.
EMS & SCADA for BESS
Integrated control and optimization for storage. Closed-loop PID, SoC management, grid-forming, and grid support from a single point, with sub-second response for real-time grid services.
Nexus
Proven across 5 commissioned BESS plants.
Nexus
Platform
Nexus Energy Platform
Cloud platform for live monitoring, alarms, historical data, setpoints, and remote management of the whole portfolio from one screen.
Station status
Live online
SCADA for Solar PV
>400 kW
Remote control & HEDNO compliance
Advanced remote control and telemetry fully compliant with DSO requirements, including DEDDIE specifications. Secure encrypted communication (IEC 60870-5-104 / IEC 61850), real-time data exchange with grid operators, remote command execution, and event logging for regulatory compliance.
Process
How your plant goes live in Nexus
We start from the station's real equipment (BMS, PCS, meters, MV/LV), not a generic template. We map it, install the redundant controller, and deliver operational visibility and control inside Nexus.
Technical site mapping
We document capacity, BMS, PCS, meters, MV/LV, communications, and project obligations.
Redundant controller
We install the clustered PPC (Advantech MIC-770 V3) with automatic failover and field accessories.
Protocols & network
Modbus, IEC 61850, IEC 104/101, MMS & GOOSE in the field and IEC 104 toward HEDNO, with supervision UI.
Live operations & market
Closed-loop control, live monitoring, alarms, setpoints, and data ready for aggregator workflows.
Why Nexus
Built for BESS and Solar PV
Six reasons operators and aggregators choose Nexus over generic SCADA platforms.
Scalable
Cloud-native fleet management
From one site to a national portfolio — the same platform, the same dashboard, zero reconfiguration.
<600ms
7,000+ signals, 1-second loops
High-speed parallel data acquisition with sub-second response for real-time grid services.
Zero-trust
Enterprise authentication & encryption
Role-based access, encrypted channels, and immutable audit logs across all user and system interactions.
Redundant
Clustered PPC & dual storage
Redundant on-site hardware with automatic failover and dual cloud backup — no single point of failure.
Compliant
Full grid-code & DSO/TSO support
Pre-deployment validation, HEDNO certification, and continuous compliance monitoring built in.
AI/ML
Predictive analytics & fleet insights
Machine learning tools for anomaly detection, performance forecasting, and fleet-wide optimization.
FAQ
