Prepared for lenders, CDCs, and federal agencies to SBA SOP 50 10 8, USDA 7 CFR Part 5001, and conventional underwriting standards. Fiduciary duty runs to the lender and the agency, never the borrower. 4,000+ engagements since 1998 covering $41.2 billion in evaluated project value. So far in 2026: 41 engagements and $1.54 billion evaluated — 17 SBA, 11 USDA.
Biomass feasibility rests on fuel-supply security: the wood waste, agricultural residue, or municipal stream under contract within economic haul distance, fuel-cost escalation exposure, the PPA or thermal offtake behind revenue, and the emissions-compliance capital the technology requires. Waste-to-energy projects add tipping-fee revenue and municipal-contract analysis.
The analysis maps fuel supply with contract review, models delivered fuel cost, reviews offtake terms, and benchmarks capital and operating costs against comparable plants. Coverage is tested under fuel-cost escalation.
Every Wert-Berater financial model is fully linked with no hardcoded values, so any reviewer can stress any input. Deliverables comprise a complete narrative report and the linked Excel model, with ten-year pro forma, sensitivity analysis at ±5, 10, and 15 percent, interest-rate stress from +0.5 to +3.0 percent, and ratio analysis benchmarked against RMA and IBISWorld data.
SBA engagements are prepared to SOP 50 10 8, including its debt-service-coverage minimums of 1.15x operating and 1.00x global. USDA engagements follow RD Staff Instruction 5001 across the Business & Industry, Community Facilities, REAP, and Value-Added Producer Grant programs. Conventional engagements are built to the lender's stated coverage standard, typically 1.20x. Clean-energy engagements are prepared to USDA 7 CFR Part 5001 where REAP and B&I apply — including the energy-production documentation, incentive analysis, and payback arithmetic REAP requires — and to conventional and institutional standards otherwise, with interconnection and incentive risk addressed directly rather than assumed away.
Representative clean-energy work includes a $52,688,000 green carbon project evaluation and renewable-energy feasibility within the firm's USDA REAP and B&I practice. Independence is non-negotiable: determinations follow the evidence and are not revised under pressure, and studies are built to pass lender, agency, and third-party review without exception items.
A biomass & waste-to-energy feasibility study is not a technology review or an environmental impact summary. It is a credit-grade economic analysis that answers the question a lender must answer before committing capital: can this plant service its debt under realistic, documented assumptions about fuel supply, output pricing, and operating cost? Every engagement begins with the fuel stack—what feedstock is under contract, what volume is available within economic haul distance, and what happens to delivered cost when diesel prices rise or competing buyers enter the market. From that foundation the model builds forward through conversion efficiency, capacity factor, power or thermal output, and revenue under the applicable offtake or tipping-fee arrangement.
Demand analysis for a biomass or waste-to-energy project is not a population-growth projection or a consumer-survey exercise. It is a supply-chain audit on one side and an offtake-market verification on the other, and the two sides must close before any revenue assumption is credible.
On the fuel-supply side, the analyst reviews state forestry agency timber-harvest records, agricultural-extension residue-availability data, and municipal solid waste diversion reports to establish the realistic feedstock pool. Utility interconnection queues and state public-utility commission filings identify existing and permitted competing generators that draw on the same wood-waste or agricultural-residue stream. Air-quality permit registries reveal which industrial boilers and co-generation facilities already hold rights to burn the same material. Where a waste-to-energy component is present, county and municipal solid waste management plans, landfill-diversion mandates, and existing hauler contracts define the available tipping-fee volume and the competitive landscape for that stream.
On the offtake side, the analyst reviews the executed or draft power-purchase agreement against the relevant utility or ISO tariff structure, confirms interconnection status through the applicable grid operator queue, and benchmarks the contracted rate against recent comparable PPA pricing reported in public regulatory filings. Thermal-energy offtake is verified against the anchor customer’s load profile and contract term. The result is a demand picture built from primary documents and public records, not from a market-research vendor’s headline figure.
Four inputs drive the debt-service-coverage ratio in a biomass or waste-to-energy project more than any others. A study that does not stress each of them independently—and in combination—has not answered the lender’s question. The fully linked Excel model used in every Wert-Berater engagement has no hardcoded values, so a reviewing credit officer can move any of these inputs and watch every downstream ratio recalculate in real time.
Each lending channel applies its own coverage standard and documentation requirement, and biomass & waste-to-energy projects attract scrutiny that a conventional commercial real estate loan does not face.
SBA lenders reviewing a biomass project under SOP 50 10 8 require a feasibility study that demonstrates 1.15x debt-service coverage at the operating level and 1.00x at the global level. Because fuel supply is an operating risk rather than a market-demand risk, the SBA-compliant study must address contract term relative to loan maturity, counterparty concentration, and the cost consequence of spot-market fuel procurement if a supply contract lapses. The study must also address the borrower’s relevant management experience, which for a first-of-kind technology configuration is a material underwriting concern.
USDA Rural Development engagements under 7 CFR Part 5001—whether structured as Business & Industry guaranteed loans or REAP grants and loan guarantees—require energy-production documentation, an incentive analysis, and the simple-payback arithmetic REAP mandates. REAP eligibility also requires that the project meet the definition of a renewable-energy system, which for certain waste-to-energy configurations depends on the feedstock classification under applicable EPA and state rules.
Conventional lenders typically require 1.20x coverage and place particular weight on offtake-contract term relative to loan maturity, technology-provider warranty and performance-guarantee terms, and the adequacy of the debt-service reserve. An independent study that addresses each of these directly—rather than deferring them to the borrower’s projections—reduces the credit officer’s exposure and shortens the underwriting timeline.
Every engagement begins with a fixed, quoted fee delivered within one business day of the initial inquiry. The fee does not vary with the study’s finding, and no portion of it is contingent on loan approval or project completion. That structure is not a policy preference; it is the condition that makes the study credible to a lender or agency reviewer who knows that a contingent-fee analyst has an economic interest in a favorable conclusion.
Standard delivery is ten to fifteen business days from a complete data room. The data room for a biomass or waste-to-energy project must include executed or draft fuel-supply contracts, feedstock volume and pricing documentation, the offtake agreement or term sheet, interconnection or thermal-delivery documentation, a construction cost estimate from the technology provider or EPC contractor, and any existing air-quality permit applications or approvals. Incomplete data rooms extend the timeline; the engagement clock does not start until the file is complete.
Rush delivery is available for time-sensitive loan committee deadlines. Once the study is complete, the fully linked Excel model is published to a secure client portal where it remains live: a lender, agency reviewer, or credit officer can change any input and watch every ratio recalculate without requesting a revised report. The narrative report includes an explicit statement of conditions—the assumptions on which the conclusions rest—so that any material change in project terms triggers a clear, documented basis for re-evaluation rather than an ambiguous exception item.
The fee is fixed and quoted within one business day of the initial inquiry. It does not vary with the study’s finding and is never contingent on loan approval or project outcome. Because project scope, data complexity, and lending-program requirements differ, the firm quotes each engagement individually rather than publishing a schedule.
Standard delivery is ten to fifteen business days from a complete data room. For biomass and waste-to-energy projects, completeness means executed or draft fuel-supply contracts, feedstock pricing documentation, the offtake agreement or term sheet, interconnection status, a construction cost estimate, and any air-permit filings. Rush delivery is available when a loan committee deadline requires it.
Fuel-supply risk is the primary difficulty. Unlike solar or wind, a biomass plant’s operating cost depends on a physical commodity that must be contracted, transported, and priced over the loan term. Competing buyers, contract gaps, moisture variability, and emissions-compliance capital all move the coverage ratio in ways that a standard renewable-energy model does not capture. A credible study must stress each of those inputs explicitly.
REAP requires energy-production documentation, an incentive analysis, and simple-payback arithmetic. For larger loan-guarantee requests under REAP or the Business & Industry program, USDA Rural Development typically requires a full independent feasibility study prepared to 7 CFR Part 5001. The specific threshold and documentation requirements depend on the program and loan amount; lenders should confirm current agency guidance with their USDA Rural Development state office.
A single study can be structured to address both sets of requirements, but the coverage standards and documentation mandates differ. SBA SOP 50 10 8 requires 1.15x operating and 1.00x global coverage. USDA 7 CFR Part 5001 imposes its own energy-production and incentive documentation. When dual-program compliance is needed, the engagement scope is defined accordingly from the outset.
At minimum: executed or draft feedstock supply contracts with volume, pricing, and escalation terms; any spot-purchase history if the plant will rely on open-market procurement; haul-distance and transport-cost data; and feedstock energy-content or moisture specifications. For waste-to-energy projects, municipal waste-acceptance agreements and tipping-fee schedules are also required. The engagement clock starts when the data room is complete.
