10,2 — Project IRR
12,8 — Levered Equity IRR
Analysis of the Project Return and the Levered Equity Return (for the proposed UK guaranteed debt levels) and at the negotiated SP.
The 10,2 % is due to the tax shield effect on project level cash flows and indicative IUK Guarantee pricing.

Notes:
(1)
Includes construction gain share benefit of GBP 0,8/MWh (real 2012)
(2)
Lump sum from SZC only released post COD2 and therefore does not form part of funding requirement
(3)
Opex adjustment only applied for first 15 yrs and after CFD period due to potential opex reopener protection.
(4)
Min DSCR excluding first period
(5)
EIRR committed real approximated as EIRR committed nominal minus long term CPI assumption
(6)
Lower level of Committed equity assumed in this version of the Financial Model will mean Committed Equity IRR is optimistic v current modelled results

( *1 ) While the UK's submission quotes 9-15 per cent post-tax nominal rates of returns from the source given in (2), the Commission notes that this seems to ignore the ‘
regulated and concession
’ projects mentioned in that source. The Commission understands from (2) that the regulated and concession activities of GDF-Suez are indicated to realise around 5-13 per cent post-tax nominal project returns, with the most likely range being below 10 per cent.
