The document discusses various options for financing renewable energy projects, including through balance sheet and off balance sheet structures. It explains key concepts like non-recourse and recourse debt, as well as equity financing and mezzanine loans. The risks associated with different financing options are outlined, noting that own development carries the most risk but also the greatest rewards and control, while third party structures transfer most risks but also benefits.

16. Risk & Reward
Risk increases the cost of finance, restricts the
options for finance and adds to the cost of
obtaining finance.
Identifying and managing risk will improve all
these finance issues.
Risk management may involve a partnership
approach.
16
17. Types of Risk
Financial risks, capital costs, energy prices,
credit risks and inflation
Development risks, the costs of undertaking
feasibility and the risk of planning
Construction risks, construction costs and long
lead in times
Technology risks, particularly around efficiency
and reliability of the technology
Operational risks, operational and maintenance
costs, fuel availability
Policy risks, changes to renewable energy policy
and incentive structures = investment returns
17
18. Risk Description
Capital costs higher than budget
See Copy Operational costs higher than budget (including maintenance, interest rates and insurance)
Cost of finance higher than expected
of Guide: Economic /
Borrowing conditions breached and associated risks
Page 5
Risks associated with energy price fluctuations
Financial
Carbon prices reduce
New competitors in the market
Rate of inflation
Currency risks (if cross-border projects, or if purchasing components in other currencies)
Cost of resource assessment and feasibility studies
Cost of environmental impact studies, EIA reports etc.
Cost of grid connection assessments
Development
Planning time longer – delay in generation income / possible lower incentive value received
Failure to gain planning consent
Development partners disagree and part company
Planning consent requires cost to comply with conditions
Construction costs higher than budget
Construction
Construction time longer, delaying income from generation
Connection to energy networks delayed
Costs of impact assessment (often a legal requirement) higher than budgeted
Environmental
Issues identified during impact assessment delay or prevent project development
/ social
Costs of mitigation actions higher than budgeted
Technology less efficient than predicted, so less energy produced
Technology
Technology less reliable than expected, less energy produced and higher maintenance costs
Renewable energy resource is lower than predicted (e.g. lower wind speed)
Access to site prevents repair or maintenance
Replacement parts required
Delays in supply or installation of spare parts
Operational
Fuel costs higher than expected (e.g. biomass fuel costs higher or there is an increase in price of
electricity for heat pump projects)
Fuel supply problems, (poor quality or interruptions in delivery)
Site energy use falls, reducing the value of avoided energy costs
Planning requirements changed
Capital grants removed or oversubscribed
Revenue incentive removed or reduced in value
Policy
Eligibility for capital grants or revenue incentives changed
Finance sector regulatory changes, reducing availability, and cost, of finance
Tax treatment changed
18
19. Assessing Risk
For each type of risk:
– How could your project be affected?
– How significant are the impacts?
– How could you reduce the risks?
– How could someone else reduce the risks?
19
20. Financing options
Type Examples
– Internal funding
Own – Debt finance
development – Equity finance
– Leasing
– Partnership – majority control
Partnership
– Partnership – equal split
structures
– Partnership – minority control
– Land lease agreements
Third party – Service concessions
– Energy Service Companies (ESCOs)
20
21. Own Development
Greatest control + Rewards + Risks
Internal Funding
– Business Case and internal reviews
– May not be deemed core business
External Funding
– Grants or low cost loans
– May be incompatible with income from the FIT or
RHI etc
21
22. Own Development
Debt Finance:
– Full ownership of rewards and risks
– Likely to be part of capex (so need internal funds)
– Added costs of interest payments
– Capital repayments
– May be step in-rights
22
23. Partnership Development
Many different forms of partnership
Different structures, benefits and risks
Majority control
– You closely control risks
– Partners bring niche skills or assets
Minority control
– Driver is not financial – reward share is low
– Partner controls
– Can you gain what you hope for without control?
23
24. Third Party
Transfer of almost all aspects
Best when you lack the skills and capital
Small income – e.g. land rent
24
25. Service Concessions
Useful for the public sector
Grant a right to develop and exploit a resource
Often long term (25 years)
Payments made to public authority
– (fixed + revenue elements)
Used for energy from waste contracts and other
renewables
25
26. Choosing an Option
What are your drivers and expected outcomes?
Does the arrangement provide these outcomes?
Which risks are retained?

28. Sources of Finance
Two main options – but many variants
On Balance Sheet:
– Part of normal activities of the organisation
Off Balance Sheet:
– Separate company who owns the asset
28
29. On Balance Sheet
Balance Sheet Debt
– Usually through a bank as a loan
– Banks have the first claim on the assets of a
business (senior debt).
– Bank loans are lower risk = lower returns
– Two main types of bank debt:
Non recourse
Recourse
29
30. On Balance Sheet
Non recourse debt:
– Loan is secured on the value & income of the asset
– Bank focuses on the value and income of the asset
Will it perform? Will it break down?
– Added scrutiny on the asset
– Not as suitable for higher risk projects
– Lender will limit the risk e.g. 75% debt
– Fixed at outset, all consents etc. needed
– Often needs special purpose company
– Higher costs to set up
– Typically larger projects (> £25 million)
30
31. On Balance Sheet
Recourse debt:
– Loan is secured by the borrower
– Bank focuses on the credit status of the borrower
– May suit higher risk projects
– May not suit borrowers with high levels of existing
borrowing
31
32. Practical example
Non recourse finance
– Large wind investments typically need 1 year of on
site wind measurements + detailed analysis
– Cautious use of wind data
– Adds to development cost
– Adds to development timescale
– May miss higher incentives
Recourse finance
– Farmers securing loan for 1 MW wind turbines
against the farm
– No met mast = saving 18 months + costs
32
33. Lessons from Non Recourse
The tests are tougher because they are external
Debt Service Cover Ratio: The operating cash
flow compared to the debt payments?
– Aim for at least 1.3 : 1 in any operating year
Loan Life Cover Ratio: The operating cash flow
compared to the debt payments over the entire
term of the loan?
– Aim for at least 1:5 : 1
33
34. Lessons from Non Recourse
Debt Service Reserve: The cash kept to cover
debt payments:
– In Project Finance – typically 6 months debt
payments
Maintenance Service Reserve: The cash kept to
cover maintenance:
– Often at least 3 months
P90 output: The output which will be exceeded
90% of the time.
34
35. Output and Cash Flow
Three hydro schemes in Argyll
Use bank thinking in the business case
35
36. Balance Sheet Equity
Raise funds by creating and selling new shares
Shareholders gain via:
– A share of the operating profits (dividends)
– Capital value in price of shares
– Must be possible to sell share – all investors need
an exit strategy
36
37. Mezzanine loans
Think of buildings = Half way between bank debt
and equity
Can take higher risk
Do not have highest call on assets
Short duration
Higher cost
Used to fill a funding gap
Replaced with lower cost finance once risks
reduced?

Which type of debt finance is this?
47
48. Project Finance Example
Bank will typically lend 70% - 90% of the project
cost (dependant on technology )
Landowner will need to invest the remainder
Term of up to 15 years
Lend of between £1m and £25m
Lent against the forecast future cash flows
Bank will require legal, technical, financial and
insurance overview

investment
48
49. More on Incentives
FIT & RHI – Covered in Part 1
Renewables Obligation – generally for projects >
5 MW
CCL – Renewables is exempt worth £4.85/MWh
for electricity
CRC – Can be avoided – but better to claim FIT
49
50. More on Incentives
EU-ETS – Large sites only, renewable heat would
avoid purchase of fossil fuel and need fewer EU-
ETS allowances
CCA – Larger sites – Cant claim if earn FIT or RHI
Public Capital Grants – Cant claim FIT or RHI
– Some expenditure is eligible (development, heating
network)
– Private sector grants are OK
50
51. More on Incentives
Enhanced Capital Allowances – a benefit against
corporation tax paid. Not available if FIT or RHI is
earned
Business rate relief – Stepped by scheme size,
100% relief for small schemes, to 2.5%

61. Knowledge Review
How much did they borrow?
What was the annual interest payment?
How much income (£/yr) from the FIT is due?
What is the net annual income?
61
62. Knowledge Review
How much did they borrow?
– £1.125 million (75% x £1.5 million)
What was the annual interest payment?
– £78.8k pa (7% x £1.25 million)
How much income (£/yr) from the FIT is due?
– £247k pa (9.5 p/kWh x 2,600,000 kWh)
What is the net annual income?
– (FIT + Export – Interest – O&M)
– (£247k + £117k) – (£78.8k + £44.2k)
– (£364k) –(£123k) = £241k
