38 North Power Station Key Points The first phase of the new diesel power station must be commissioned by May Government approvals must be obtained by May 1 st, The need for new diesel plant is primarily driven by the essential and imminent retirement of the Old Power Station which has the highest environmental impact. Intermittent Renewable Energy Sources are incapable of replacing retired diesel plant at this time. The Central Power Plant is the only site available for a diesel power station development at this time. 37
