Unit Outage at Tekapo B

MARKET RELEASE
Date: 21 December 2017
Unit Outage at Tekapo B

Genesis Energy is notifying the market that it has completed an assessment of Tekapo B Generator 3 that
suffered a fault in November. This unit is now expected to return to service at full capacity in early March.
Tekapo A and the second unit at Tekapo B are operating as normal.

Whilst the recent firm wholesale prices are positive for Genesis, the Generator 3 outage will have an offsetting
effect on the second half FY18 earnings, however Genesis Energy’s EBITDAF guidance for FY18 remains
unchanged.

Genesis Executive General Manager of Generation and Wholesale Tracey Hickman says the fault occurred when
the unit was being returned to service following a planned outage.

“The strategic benefit of Genesis’ diverse generation portfolio is helping to offset the loss of 43% of the Tekapo
Power Scheme’s generating capacity,” says Hickman.

Genesis will provide a further update on the outage as part of its FY2018 Half Year result announcement to be
released on 14 February 2018.
