voltengine 0.1.2

Utility-grade electricity billing engine supporting prepaid, LT and HT consumers

⚡ VoltEngine

The Universal Utility Billing Framework

VoltEngine is an industry-ready Python library designed to automate complex electricity billing cycles. From simple domestic slab rates (LT) to complex industrial demand charges (HT), VoltEngine provides a modular math-heavy core to ensure zero-error invoicing.

🎯 Domain Coverage

• LT Postpaid: Residential/Commercial slab-based billing.
• LT Prepaid: Real-time credit-to-energy conversion logic.
• HT (High Tension): Industrial billing featuring Demand Charges, Power Factor (PF) adjustments, and Time-of-Day (ToD) tariffs.

⚙️ Core Logic Flow

The engine processes data through a structured pipeline to ensure compliance with regulatory standards:

1. Input Layer: Consumes KWh (Active), KVAh (Apparent), and MD (Maximum Demand).
2. Tariff Resolver: Matches consumer type to specific state/utility rate cards.
3. Calculation Engine: Processes fixed charges, energy charges, and penalties.
4. Taxation Module: Applies Duty, GST, and Surcharges.
5. Output Layer: Generates a structured JSON objects ready for PDF invoicing or API consumption.

🛠️ Tech Stack

• Engine: Python 3.10+ (Logic & Math)
• Validation: Pydantic (Data integrity)
• API Layer: FastAPI (High-speed integration)
• UI/Simulator: Streamlit (For real-time billing simulation)
