Energy Metrics​

Specific Energy Consumption (SEC)​

SEC = Total Energy (kWh) / Total Water Processed (kL)

Pump Efficiency​

Efficiency = (Output Power / Input Power) × 100%

Energy Cost​

Total Cost = Σ (Energy (kWh) × Tariff Rate (₹/kWh))

Energy Intensity​

Intensity = Energy Consumed / Production Output

}

Usage Examples​

Calculate Energy Cost​

const calculateEnergyCost = (kWh, tariffRate) => {
  return kWh * tariffRate;
};

// Peak hours (₹8/kWh)
const peakCost = calculateEnergyCost(5000, 8);

// Off-peak hours (₹5/kWh)
const offPeakCost = calculateEnergyCost(3000, 5);

Energy Efficiency Calculation​

const calculateEfficiency = (pumpData) => {
  const theoreticalEnergy = pumpData.flowRate * pumpData.head * 2.725;
  const actualEnergy = pumpData.energyConsumed;
  return ((theoreticalEnergy / actualEnergy) * 100).toFixed(2);
};

Integration​

  • True Cost of Water - Energy cost component
  • HMI Interface - Real-time energy monitoring
  • Dashboard - Energy summary card
  • Alerts - Energy threshold violations
