RENEWABLE ENERGY EXCEL DESCRIPTION
πΏ BIOGAS & WASTE-TO-ENERGY
20-YEAR CHP PROJECT FINANCE & INVESTMENT MODEL
β‘ FROM FEEDSTOCK ECONOMICS TO LONG-TERM INVESTMENT RETURNS
Transform biogas plant assumptions into a comprehensive, interconnected financial planning framework with this professional 20-year Excel model.
The Biogas & Waste-to-Energy Financial Model integrates anaerobic digestion, organic feedstock management, combined heat and power (CHP) generation, operating economics, project financing and investment analysis.
Developed for renewable energy professionals, biogas developers, infrastructure investors, feasibility consultants and financial analysts, the model provides a structured way to evaluate illustrative project economics, explore alternative scenarios and identify financial risks.
With 15 interconnected worksheets, 500 prepared feedstock rows, 8 native Excel dashboard charts and 4 selectable scenarios, the workbook connects physical plant operations with financial projections.

π EXECUTIVE INVESTMENT DASHBOARD
A dedicated executive dashboard brings together project performance, profitability, financing coverage and investment returns in one integrated overview.
The dashboard includes 8 linked, native Excel charts and key financial indicators:
β’ First-Year Feedstock Throughput
β’ Net Electricity Generation
β’ Revenue per Tonne
β’ EBITDA
β’ Unlevered Project IRR
β’ Levered Equity IRR
β’ Project NPV
β’ Minimum Loan-Year DSCR
β’ Gross Levelized Cost of Electricity (LCOE)
β’ Electricity Cost After Coproduct Credits
Visualize revenue composition, operating profitability, debt repayment, cash flow trends and financing coverage.
The selected scenario and internal model-check status remain visible alongside the executive metrics.

βοΈ FEEDSTOCK MANAGEMENT & BIOGAS OPERATIONS
Connect organic waste inputs directly to physical plant production and operating economics.
The workbook contains 500 prepared feedstock entry rows, including 15 illustrative organic waste examples.
Editable assumptions include:
β’ Annual Wet-Tonne Feedstock Quantities
β’ Methane Yield and Feedstock Quality
β’ Feedstock Rejection Rates
β’ Gate Fees and Tipping Income
β’ Feedstock Procurement Charges
β’ Transportation and Logistics Expenses
β’ Digestate Sales and Disposal Costs
β’ Processing Capacity and Plant Availability
The operations schedule links feedstock inputs to annual methane production, biogas volumes and CHP energy generation.
Calculated outputs include:
β’ Accepted Feedstock Volumes
β’ Methane and Biogas Production
β’ Gross CHP Electricity Generation
β’ Auxiliary Electricity Consumption
β’ Net Electricity Available for Sale
β’ Recoverable Heat Production
β’ Digestate and Residual Disposal Volumes
Additional operating drivers include commissioning ramp-up, methane losses, CHP capacity constraints, equipment availability and electricity-yield degradation.
ββββββββββββββββββββ
π° FOUR CONNECTED REVENUE STREAMS
Analyze the combined commercial value of electricity generation, recovered heat and organic waste processing.
The financial model separately evaluates four principal income sources:
β Electricity Sales
β‘ Recovered Heat Sales
β’ Feedstock Tipping Fees
β£ Digestate Sales
Operating cost projections include feedstock purchases, transportation, residual disposal, maintenance, variable processing expenses and fixed plant operating expenditure.
The integrated calculations provide annual operating revenue, cost escalation, EBITDA and revenue per tonne across the forecast period.
ββββββββββββββββββββ
ποΈ CAPITAL EXPENDITURE & PROJECT FINANCING
Structure initial project investment and connect capital requirements directly to construction funding.
The CAPEX framework includes 12 editable investment categories.
Funding assumptions incorporate:
β’ Senior Project Debt
β’ Capital Grants
β’ Sponsor Equity Contributions
β’ Construction Funding Requirements
The linked debt schedule calculates annual interest expenses, scheduled principal repayments, debt service and closing loan balances.
Three integrated financial statements support the complete investment analysis:
π Income Statement
π΅ Cash Flow Statement
π¦ Balance Sheet
The financial statements connect revenues, operating expenses, depreciation, taxation assumptions, loss carryforwards, working capital, maintenance CAPEX, financing movements and shareholder distributions.
The model includes one initial construction period followed by 20 annual operating periods.
It is an annual project finance model rather than a monthly construction-financing tool.
ββββββββββββββββββββ
π INVESTMENT RETURNS, DSCR & LCOE
Evaluate investment attractiveness from both project-level and sponsor-equity perspectives.
The RETURNS LCOE worksheet includes:
β’ Project Internal Rate of Return (IRR)
β’ Equity Internal Rate of Return (IRR)
β’ Project Net Present Value (NPV)
β’ Equity Net Present Value (NPV)
β’ Equity Investment Multiple
β’ Annual Debt Service Coverage Ratio (DSCR)
β’ Minimum Loan-Year DSCR
β’ Gross Discounted LCOE
β’ Coproduct-Credit-Adjusted Electricity Cost
β’ Cumulative Electricity Generation
β’ Cumulative Feedstock Processing
These calculations help distinguish project economics from equity investor outcomes while assessing debt-service coverage and electricity production costs.
ββββββββββββββββββββ
π FOUR SCENARIOS & SENSITIVITY ANALYSIS
Explore alternative project conditions through four selectable scenarios.
π’ BASE
Reference operating and commercial assumptions.
π΅ UPSIDE
More favorable modeled project conditions.
π DOWNSIDE
Adverse operating and financial assumptions.
π΄ STRESS
More severe operating and investment conditions.
Scenario adjustments cover relevant drivers including:
β’ Methane Production Yield
β’ Electricity and Energy Prices
β’ Feedstock Availability
β’ Plant Downtime
β’ Commissioning and Launch Timing
β’ Capital Expenditure
β’ Operating Expenses
The selected scenario recalculates the connected operating schedules, financial statements and investment metrics.
A separate SENSITIVITY worksheet provides indicative single-driver impacts on first-year EBITDA and directional NPV estimates.
Important: The sensitivity worksheet is not a complete multi-variable, full-forecast sensitivity engine.
Downside and Stress scenarios may produce negative cash balances, financing gaps, negative NPV or mathematically undefined returns. These outcomes represent project risks requiring investigation.

BUILT-IN MODEL CHECKS & FINANCIAL CONTROLS
The workbook includes dedicated internal model checks designed to identify selected calculation and reconciliation issues.
Control areas include:
β Feedstock Input Constraints
β Methane and Mass Accounting
β CHP Capacity Constraints
β Digestate Allocation
β Sources and Uses of Funds
β Debt Balance Movements
β Cash Flow Reconciliation
β Financial Statement Consistency
β Negative Cash Balance Warnings
Editable INPUT fields and calculated AUTO fields are visually distinguished.
