Importance of financial and economical assessment
Importance of financial and economical assessment installations

Complicated

No fun (for most people)

Without sound financial/economic assessment no funding from governments for biogas programs

Decision whether or not to implement in specific country

Without clear information it is hard to make people purchase the biogas installation

Assessing value
Assessing value installations

Cost-based approach:

  • Investment and repair costs, divided by total (expected) gas production;

  • Interest, depreciation and repair costs over its lifetime, divided by the total (expected) gas production;

  • Total operating and maintenance labour expected over its lifetime, divided by the total (expected) gas production;

  • Benefit-based approach:

  • Total value of substituted fuels divided by the corresponding amount of biogas generated of that period;

  • Total value of increased agricultural produce and substituted fertilizer;

  • Total value of (productive) time saving resulting from operating a biogas plant as compared with using traditional fuel;

  • Total value of improved health and sanitation conditions;

  • Total value of a better life

Or a combination of the above?

Financial vs economic costs and the gigajoule
Financial vs. Economic costs and the gigajoule installations

  • Financial costs: for the project/individual

  • Economic costs: for the society/country

    G Gas: 33.38 MJ/m3

    One gigajoule is approximately 30 m3 G Gas

    Steven’s financial GJ costs for gas: €16.5/GJ

    Average Dutch household uses1576 m3 (52.53 GJ)

  • Parameters used:

    • Investment costs

    • Maintenance costs (5% of investment p.a.)

    • Biogas loan conditions (interest rate, maturity)

    • Lifetime (15 yrs)

    • Biogas production (584 m3 biogas p.a.)

Capital budgeting instruments
“Capital budgeting instruments” installations

Simple Payback Period (SPP):

Investment divided by annual (net) income

Parameters used: Cash flow

Net Present Value (NPV):

Present value (future) cash inflows minus initial investment

Interesting project: NPV > 0

Parameters used: Cash flow

Discount rate

Internal Rate of Return (IRR):

Discount rate resulting in a nett present value of zero after a series of cash flows

Interesting project: IRR > interest rate alternative investments

Parameters used: Cash flow

Considerations so far
Considerations (so far) installations

  • The cost side:

  • what is the actual price paid for the installation

    • local material and labour pricing

    • in-kind contribution of the household

  • Plant financing costs

  • The benefit side:

  • correcting for energy pricing increase

  • differences in energy pricing between areas

  • are households actually paying for their domestic fuel?

  • are households actually feeding the plant

  • and … :

  • to which extent does the investor reap the benefits

  • to which extent pays the investor for the “real” value
