Nexen EMS use cases
Power Guard—active power limit control with Nexen EMS
In industrial facilities, exceeding contracted active power limits leads to costly penalties and operational disruptions. Maintaining power within defined thresholds is essential to control energy expenses and ensure network stability. key challenges include:
- Exceeding contracted active power limits, resulting in penalty charges.
- Lack of real-time awareness of approaching power thresholds.
- Difficulty forecasting power peaks during production cycles.
- Inability to automatically reduce or delay noncritical loads when limits are near.
- Manual monitoring that leads to delayed responses and unnecessary costs.
The solution: Nexen EMS power guard functionality
Nexen EMS introduces a dedicated Power Guard feature designed to continuously monitor active power and alert operators when predefined thresholds are approached or exceeded.
How it works:
- Real-time monitoring: Continuously tracks total active power across the facility, providing minute-by-minute insights into energy performance.
- Threshold-based alerts: Sends instant notifications (via SMS, email, or system dashboard) when power consumption reaches predefined warning or critical levels.
- Predictive peak detection: Uses trend analysis and historical data to forecast when active power will likely exceed the limit, allowing proactive intervention.
- Automated load control: Optionally integrates with control systems to temporarily reduce or shift nonessential loads (e.g., HVAC systems, auxiliary equipment) when thresholds are near.
- Customizable settings: Enables defining multiple limit levels (e.g., warning, critical, emergency) per production line, shift, or site.
- Integration with Nexen Predict: Combines with predictive analytics to anticipate power peaks based on production schedules, weather, or process data.
- Optimization of contracted power: Helps define the real power profile and select the optimal contracted level. Prevents oversizing that often costs more than occasional exceedance penalties.
Result:
With Nexen EMS Power Guard, companies can prevent power limit exceedances, reduce penalties, and ensure stable, efficient, and cost-effective energy management.
Reactive power optimization with Nexen EMS
In industrial facilities, efficient energy management begins with understanding active and reactive power. While active power performs useful work, reactive power—though necessary for the operation of motors, transformers, and lighting systems—does not contribute to production.
Reactive power comes in two forms:
- Inductive reactive power generated by motors, transformers, and induction furnaces.
- Capacitive reactive power produced by LED lighting, UPS systems, long cables, and PV inverters.
When tg φ exceeds 0.4 or cos φ drops below 0.9, a power system becomes inefficient. Utilities then apply penalties for excessive reactive energy, both inductive and capacitive often adding 30–40% to the total electricity bill.
Consequences of excessive reactive power:
- Higher electricity costs and surcharges.
- Lower overall energy efficiency.
- Increased transmission losses and overheating.
- Transformer and cable overloads.
- Voltage fluctuations and poor power quality.
- Shortened equipment lifespan and risk of failure.
The Solution: Nexen EMS
Nexen EMS provides a complete solution for measurement, analysis, and optimization of reactive power. It continuously tracks cos φ, tg φ, voltage, current, and other power parameters—helping identify inefficiencies and sources of reactive power.
How it works:
- Monitors energy performance in real time.
- Automatically compensates or stores reactive power using capacitor banks or hybrid systems.
- Helps to maintain tg φ ≤ 0.4 and cos φ ≥ 0.9 to avoid penalties.
- Improves power quality and network stability.
- Extends the lifespan of your electrical infrastructure.
Result:
Lower costs, higher efficiency, and full control of your energy performance. With Nexen EMS, reactive power management turns from a hidden expense into a measurable business advantage.
Energy optimization of production processes with Nexen EMS
In manufacturing, energy consumption represents one of the highest operating costs. Yet its optimization poses many challenges:
- Limited insight into energy usage by process or production line.
- Inability to track consumption trends or calculate performance differences.
- Power peak exceedances leading to costly penalties.
- No clear correlation between energy use and production output.
- Lack of defined KPIs and benchmarks to monitor improvement.
The Solution: Nexen EMS
Nexen EMS provides a complete, data-driven approach to monitoring, analyzing, and optimizing energy use across production processes. It transforms raw consumption data into actionable insights that directly improve efficiency and reduce costs.
How it works:
- Real-time visibility: Track energy usage by production line, process, or shift to identify inefficiencies and hidden losses.
- Trend analysis and benchmarking: Compare energy consumption over time to identify patterns, measure how usage changes between periods, and detect unusual spikes or drops that may indicate anomalies or inefficiencies.
- Peak load control: Monitor and manage peak power demand to prevent costly exceedances and grid overloads.
- Production–energy correlation: Integrate production data with energy metrics to measure true process efficiency and optimize schedules.
- Key performance indicators (KPIs): Define and monitor key metrics such as energy intensity (kWh per ton of product or per shift), cost efficiency, and compliance with predicted energy price trends.
- Data-driven decision-making: Use precise measurements to assign energy costs to specific products, processes, or shifts, enabling better budgeting and accountability.
Result:
With Nexen EMS, manufacturers can make smarter operational decisions, align production with energy economics, and achieve measurable improvements in efficiency, cost reductions, and improved sustainability.
Environmental monitoring in warehouses
In warehouse environments, maintaining stable environmental conditions is critical for protecting goods, ensuring regulatory compliance, and maintaining safe working conditions. However, managing these parameters across large facilities presents several challenges:
