For kVA demand (common for utilities), measure voltage and current, then:

# Store in circular buffer self.buffer[self.index] = delta_kwh self.index = (self.index + 1) % self.num_blocks maximum demand electrical

# Calculate total kWh in complete window total_kwh = sum(self.buffer) demand_kw = total_kwh / (self.window_size / 60.0)

Demand = (kWh_last_15min) / 0.25 To avoid storing raw energy every second, break window into N sub‑intervals.

Demand (kW) = (Energy consumed over window T) / (T in hours) Example for 15‑min window (0.25 hours):
