Why the DPR decides your CBG plant's success
A CBG plant's economics depend on assumptions: how much gas each tonne of feedstock produces, how many days the plant runs, what the feedstock costs delivered to the gate, and what CBG and FOM will sell for. If those assumptions are optimistic, the plant is financed on numbers it cannot achieve. A robust DPR uses realistic, feedstock-tested yields and conservative scenarios.
Contents of a bankable CBG plant DPR
| Section | What it must cover |
|---|---|
| Executive summary | Capacity (TPD), feedstock, technology, cost, funding and returns |
| Feedstock assessment | Availability within the economic radius, seasonality, lab analysis (TS, VS, C/N), delivered cost, supply contracts, storage |
| Process design | Mass and energy balance, pretreatment, digester sizing, retention time, organic loading rate |
| Technology selection | Digester type, agitation, gas storage, upgrading route, compression and dispensing or pipeline |
| Site & layout | Land, CLU, plot plan, safety distances, utilities, logistics |
| Capital cost | Equipment, civil, electrical, automation, pre-operative costs, contingency. See cost guide |
| Operating cost | Feedstock, power, manpower, consumables, maintenance, insurance |
| Revenue model | CBG offtake, FOM/LFOM sales, Market Development Assistance, carbon credits |
| Financials | Projected P&L, cash flow, DSCR, IRR, payback, sensitivity on yield, uptime and price |
| Subsidy & incentives | GOBARdhan capital assistance and applicable state incentives. See subsidy guide |
| Approvals & schedule | PCB, PESO, fire, electrical, registration, and a realistic implementation timeline |
| Risk & mitigation | Feedstock, biological, technical, market and regulatory risks |
Red flags in a CBG project report
- Gas yield copied from literature with no lab test of your feedstock (sanity-check it with our yield calculator)
- 365-day operation with no allowance for maintenance or seasonal shortage
- No pretreatment cost for fibrous biomass like paddy straw or Napier grass
- Digestate revenue assumed without dewatering, processing or a market plan
- No sensitivity analysis
Biovardhan's DPR approach
We prepare DPRs from feedstock data and our own engineering design, so the report matches the plant we would actually build and guarantee. Request a DPR consultation, or start with our CBG project roadmap.
Frequently asked questions
Sample reports are available online, but a generic PDF cannot reflect your feedstock, land, offtake and costs. Banks and lenders expect a project-specific DPR with feedstock test data and realistic gas-yield assumptions.
Feedstock characterisation and supply plan, mass and energy balance, gas yield assumptions, technology selection, plant layout, capex and opex, revenue from CBG and FOM, financial statements, sensitivity analysis, implementation schedule, statutory approvals and risk mitigation.
Yes. DPR preparation is part of our project development support and is based on feedstock assessment and our engineering design, so the report matches the plant that will actually be built.
A DPR is a standard requirement for bank financing and is typically needed in scheme processes to assess the project, its feedstock requirement and eligibility.
