6. Risk Management

Thailand is a good location for solar

farm given intensive solar radiation

and should be able to yield good

solar output

50% of the total area receives an

annual average solar radiation of 18

-19 MJ/m2 – day, which are

considered relatively high

GUNKUL has carefully selected proven

technology and manufacturers f rom

Solar Frontier which has an established

record

Solar Frontier as a supplier for solar

modules, and Schneider, as a

manufacturers for equipment relating to

the transformation of electric current,

provides 5 years bond guaranteeing the

performance of their equipment

GUNKUL has already secured PPA

contract f rom PEA

PPA defines a series of operating

characteristics in terms of start up

and shut down times, loading and

deloading rates

PEA guarantees that it will

purchase all electricity generated

from the farm under the contract

1. Raw Material 2. Technology 3. Offtaker

7. Contract agreement

ElectricityDebt Funding

• Total financing of THB 315

mn with interest rate of MOR – 1.5%, repayment 93 months

• Collateral: Land and

equipment of project

• Guaranteed by GUNKUL

• Key Covenant: GUNKUL maintain stake at least 75%

VSPP Non-firm PPA

with PEA Loan Agreement

• Tenor 5 years with automatic

extension of 5 years, which can only be terminated by

seller, GPG

• COD within 2 years of signing

of PPA, which in practice can

be extended if the seller can prove that they are committed

to investing in the project

• Non – firm contract because

seller cannot control sun light therefore cannot determine

when to generate electricity to

grid
