Trustpower Limited provided earnings guidance for the fiscal year 2019. For the year, the company expected EBITDAF to be in the range of $215 million to $235 million. This is an increase on its earlier guidance of $205 million to $225 million. The increased forecast is being driven by the favourable trading conditions in the year to date, and a revision of the expected trading conditions for the remainder of the year. Noting that the current trading conditions are experiencing highly volatile and elevated prices due to a gas field outage and low hydrology. Trustpower is expecting a reversion to more average trading conditions towards the end of the 2018 calendar year.
