Aliveri is mostly an industrial town. The biggest cement factory of Greece and a power generating plant of the Public Power Corporation (ΔΕΗ) are located in Aliveri. The lignite fired power plant began producing power in 1955. As the lignite seam has been exhausted now, the power plant is using oil. In the area, there is also marble mining industry. Aliveri has a picturesque harbor called "Karavos".
