Stop Revenue Losses; Stop Dumsor!! "Dumsor" (nationwide power cuts) has a stranglehold on our communities, our businesses, and our progress as a nation.

These issues significantly affect ECG's revenue, which is vital for covering operational costs and making regular payments to upstream electricity suppliers, including independent power producers.
