FINANCIAL MODELING — EXECUTIVE ROI FRAMEWORK
Corporate finance directors require transparent, auditable ROI calculations to secure board approval for captive power investments. NST Global Solar & Wind Energy provides standardized financial modeling methodologies that align with corporate treasury requirements.
Step-by-Step Savings Calculation Formula
Annual Savings = (State DISCOM Tariff − Captive LCOE) × Annual Consumption − (Wheeling Charges + Banking Losses + Regulatory Surcharges)
Net Present Value = Σ [(Annual Savings − Annual O&M) / (1 + Discount Rate)^n] − Initial Capital Outlay
Internal Rate of Return = Discount rate where NPV equals zero
Payback Period = Initial Capital Outlay / Annual Net Cash Flow
Example: 5 MW Solar CPP for Karnataka Textile Unit
State DISCOM Tariff: ₹9.2 per kilowatt-hour
Solar CPP LCOE: ₹5.8 per kilowatt-hour
Annual Consumption: 25,000,000 kilowatt-hours
Open Access Charges: ₹1.1 per kilowatt-hour
Annual O&M: ₹1.2 million
Capital Outlay: ₹19.5 crore
Discount Rate: 10 percent
Annual Gross Savings = (₹9.2 − ₹5.8) × 25,000,000 = ₹85,000,000
Open Access & Loss Deductions = ₹1.1 × 25,000,000 = ₹27,500,000
Annual Net Savings = ₹85,000,000 − ₹27,500,000 − ₹1,200,000 = ₹56,300,000
Simple Payback = ₹19.5 crore / ₹5.63 crore = 3.46 years
10-Year NPV = ₹142.8 million
Corporate treasury departments approve investments demonstrating sub-5 year payback with positive net present value across conservative scenario modeling.
