Egbema Power Station
A Power Plant project was initiated at Mmahu Egbema in 2006 under President Olusegun Obasanjo to ameliorate the sufferings of many Imo State communities. To ensure resumption of work at the power project abandoned for more than five years,the administration of Rochas Okorocha who showed displeasure at the state of the project visited the site in June 2015. The governor’s visit was to mobilise the contractors handling the project back to site as well as ensure speedy completion of the project within ten months.

The power plant, planned for an installed capacity of 380.7MW (ISO) and 338MW (Net), when completed would act as an enabler for industrialization and creation of jobs in Imo State.
