Prioritizing Renewables

ZenGrid EMS prioritizes renewable energy sources to maximize sustainability, reduce carbon emissions, and minimize energy costs. Through intelligent automation and real-time data analysis, ZenGrid EMS integrates renewable resources into the energy mix in a way that supports grid stability and optimizes energy use.

Key Methods ZenGrid EMS Uses to Prioritize Renewables​

  1. Real-Time Renewable Monitoring:

    • ZenGrid EMS continuously monitors the output of renewable sources like solar panels and wind turbines. By keeping real-time data on renewable production, the system identifies periods when renewables are most abundant and prioritizes their use over grid or fossil-based energy.

  2. Forecasting Renewable Availability:

    • Using weather data and historical production patterns, ZenGrid EMS forecasts when renewable energy sources are expected to peak. This predictive capability allows the system to prepare for high renewable output by scheduling energy-intensive activities during those times, such as charging batteries, cooling or heating spaces, or preemptively powering high-demand equipment.

  3. Load Shifting to Align with Renewables:

    • ZenGrid EMS can automate load shifting, adjusting energy consumption patterns to match renewable production. For example, it may delay certain loads until renewable production peaks or shift non-essential tasks to times when renewables are available. This load-shifting strategy ensures that the maximum amount of renewable energy is utilized in real-time.

  4. Battery Storage Management:

    • ZenGrid EMS uses battery storage to balance renewable generation and demand, charging batteries when renewable energy is abundant and discharging them when demand is high or renewable output is low. This approach not only ensures that renewables are used efficiently but also reduces reliance on the grid during peak demand, lowering costs and emissions.

  5. Setting Renewable Energy as Primary Source:

    • By default, ZenGrid EMS is configured to prioritize renewables as the primary energy source wherever possible. If renewables alone cannot meet demand, ZenGrid EMS will supplement with grid energy or stored energy. This configuration ensures that renewables are maximized in the energy mix and only resorts to secondary sources when necessary.

  6. Demand Response and Renewable Integration:

    • ZenGrid EMS participates in demand response programs that further support renewable integration. For instance, when renewable energy is abundant on the grid, ZenGrid EMS can increase local consumption (load uptake) to absorb this excess energy, helping balance the grid while meeting sustainability goals.

  7. Renewable-Based Automation Rules:

    • Through the ZenGrid EMS Rules Editor, users can create automation rules that prioritize renewables. For example, a rule could turn on specific systems (like HVAC or EV chargers) only when solar power is available, or trigger battery charging exclusively during times of high wind energy production.

  8. Dynamic Pricing and Cost Optimization:

    • When energy pricing varies based on renewable availability, ZenGrid EMS can take advantage of low-cost renewable energy by adjusting loads to times when renewables are abundant. This prioritization reduces costs for users while supporting a grid powered by cleaner, renewable energy sources.

Example Use Case: Microgrid with Solar and Battery Storage​

In a microgrid scenario, ZenGrid EMS prioritizes solar energy for all local loads whenever sunlight is available. If production exceeds immediate demand, it charges batteries with the surplus energy, ensuring that solar power is stored for later use. When demand increases or solar production decreases, ZenGrid EMS discharges the batteries to continue meeting demand without drawing from the grid. By managing both the load and storage dynamically, ZenGrid EMS maximizes renewable utilization within the microgrid.

Conclusion​

ZenGrid EMS’s prioritization of renewable energy sources is a core feature that supports cost savings, sustainability, and energy independence. Through real-time monitoring, forecasting, storage management, and demand response, ZenGrid EMS optimizes renewable usage, helping organizations and communities achieve greener, more efficient energy systems.
