MECO Energy Plans

• Continuation (and possible expansion) of energy efficiency DSM

• Planned load management DSM programs on Maui• 30 MW windfarm at Kaheawa in 2005• Completion of efficient combined cycle (Maalaea Unit 18)

on Maui in 2006• Planned Combined Heat and Power units at Manele Bay

on Lanai in 2006• Energy center at Waena on Maui (including 20 MW

combustion turbine) in 2011
