Redemption of CULS

ECOFIN WATER & POWER OPPORTUNITIES PLC (the "Company")

Redemption of the Company's 6% Convertible Unsecured Subordinated Loan Stock 2016 ("CULS")

The Trust Deed constituting the CULS, dated 29 July, 2009, provides for conversion of the CULS into Ordinary Shares. The final conversion date for the CULS was 31 May, 2016.

Under the Trust Deed, the Trustee has the right to convert any remaining CULS outstanding during the period of ten days before the date of final redemption of the CULS. In light of the current share price, it is not anticipated that the Trustee will exercise this right.

Accordingly, all outstanding CULS will be redeemed by the Company on 31 July, 2016. The CULS will be redeemed at their nominal amount, together with interest accrued up to (but excluding) the date of final repayment of the CULS being 1 August, 2016 and these payments will be made on Monday, 1 August, 2016 to CULS holders on the register on 22 July, 2016. The final interest payment will be 1.0164 pence per CULS.

In light of the upcoming redemption of the CULS, the Company will apply for the CULS to be cancelled on 19 August 2016.
