This financial model is designed to evaluate and forecast the operating and financial performance of an EV Charging Engineering, Procurement, and Construction (EPC) business, which designs, supplies, and installs end-to-end electric vehicle charging infrastructure, delivering turnkey projects from site engineering through commissioning.
The model captures project-driven revenue, civil and electrical installation economics, and monthly operating dynamics across configurable business segments. It provides a 5-year (60-month) forward-looking forecast, enabling decision-makers to assess scalability, revenue and direct cost trajectories, project-level margins, working capital requirements, and overall profitability.
Model Structure – Five Core Sections
1. Cover & Navigation
• Clear index with easy navigation.
• Summary checks confirming model structure and consistency.
• Color coding for tabs and cells
2. Input Assumptions
Key business drivers are consolidated into a centralized assumptions interface. To support granular monthly forecasting, assumptions related to the number of new contracts signed are located within the Revenue & Cost of Revenue tab.
Revenue Assumptions
The model supports industry-standard EV Infrastructure EPC revenue frameworks, including:
• Customer Segments: Fully customizable segments (default placeholders include Residential, Commercial Fleet, and Highway/Public DCFC).
• Project Specifications: Volume drivers based on the number of charging ports and pricing per port ($/Port).
• Revenue Timing: Milestone-based billing and revenue recognition.
Direct Costs (COGS) & Procurement
• Hardware: EVSE (chargers), switchgear, transformers, and balance-of-system (BOS) components.
• Execution Costs: Civil and electrical installation labor
• Soft Costs: Permitting, utility interconnection, and engineering/design expenses.
SG&A & Operating Expenses
• Variable Costs: Merchant processing fees, marketing and advertising etc.
• Fixed Costs: Management payroll, office rent, software subscriptions, fleet and general insurance.
Balance Sheet & Capital Structure Drivers
• CapEx: Vehicle fleet (trucks), tools, and office asset acquisition schedules.
• Financing: Equity injections, revolving credit facilities, and term-loan amortization.
3. Output & Analytics
Dashboard
• Revenue trends segmented by customer type.
• Gross profit and EBITDA margin evolution.
Sources & Uses
• Uses: Pre-development costs, working capital requirements, and start-up expenditures.
• Sources: Equity contributions and debt financing.
4. Integrated Financial Statements
• Profit & Loss Statement
• Cash Flow Statement
• Balance Sheet
All statements are fully integrated and dynamically linked.
5. Core Calculations
• Revenue and COGS recognition aligned with construction milestones.
• Staffing and payroll expense calculations.
• Debt schedules and capital expenditure roll-forwards.
Technical Specifications
• Fully transparent structure (no VBA or macros).
• Circular reference–free.
• Compatible with Excel 2021 or newer.
Excel 2010–2019 Users:
Certain calculations use array formulas and may require Ctrl + Shift + Enter for proper execution.
Validation & Control Checks
Built-in validation controls ensure model integrity:
• Green checkmarks (✓): Logic and calculations are consistent.
• Red indicators (✗): Inputs or assumptions require attention.
Why This Model Is Well-Suited for EV Infrastructure EPC Businesses
This model supports institutional-grade financial planning for EV charging infrastructure installers. It is specifically designed to address the "lumpy" cash-flow profile inherent in EPC and infrastructure projects, while maintaining clarity across revenue recognition, cost execution, and working capital dynamics.
