RENEWABLE ENERGY EXCEL DESCRIPTION

Biomethane RNG Plant – 10 Year Financial Model is an Excel template (XLSX) available for immediate download upon purchase.

A biomethane RNG plant is a renewable energy facility that captures biogas from organic waste sources such as agricultural residues, food waste, wastewater sludge, or landfill gas and upgrades it into renewable natural gas suitable for pipeline injection, vehicle fuel, or industrial use. The process typically involves feedstock collection, anaerobic digestion or gas capture, biogas cleaning, removal of carbon dioxide and impurities, compression, and distribution. Revenue is driven by gas production volumes, feedstock availability, energy prices, environmental credits, offtake agreements, and efficient plant operations, with success depending on reliable supply, regulatory compliance, and strong technical performance.

This 10-year Biomethane RNG Plant financial model is designed to evaluate the feasibility, operating performance, and investment returns of a renewable natural gas production facility. The model forecasts feedstock intake, biogas yield, upgrading efficiency, RNG production volumes, offtake pricing, environmental credit revenue, operating costs, maintenance, utilities, capex, financing, and debt service. It also captures key project drivers such as plant capacity, ramp-up, downtime, feedstock costs or gate fees, and methane recovery. It supports project development, fundraising, lender underwriting, and strategic decision-making for RNG infrastructure investments.

The model includes assumptions and calculations of Startup Costs, Plant Technical Assumptions (Feedstock throughput, Raw Biogas Yield, Upgrader Methane Recovery, RNG energy content, Production Losses, Utilization rates), Revenue (Gas sales, Carbon Credits, Tipping Fee), Cost of Sales, Payroll, Operating Expenses, CapEx during Operations & Depreciation, Financing through Debt, Equity & Government Grant and Exit Valuation assumptions in case of a potential sale of the business.

The model follows Financial Modeling Best Practices principles and is fully customizable.

Detailed instructions for the functionality of the model are included in the Excel file.
