Hintalo Wajirat is one of the 36 woredas in the Tigray Region of Ethiopia. It is named after its largest town, Hintalo, and the Wajirat Mountains in the southern part of the woreda. Located in the Debubawi Zone at the eastern edge of the Ethiopian highlands, Debubawi Zone, Hintalo Wajirat is bordered on the south by Raya Azebo, on the southwest by Alaje, on the west by Samre, on the north by Enderta, and on the east by the Afar Region. Other towns in Hintalo Wajirat include Adi Gudem, and Debub.
High points in this woreda include Amba Aradam, an amba or mountain north of Hintalo. Rivers include the Samre, which rises in Hintalo Wajirat. Local points of interest include the church of Mariam Nazara, built on ruins which local tradition asserts was a palace of 44 chambers built by Emperor Amda Seyon. The remaining ten rock-pillars and four chambers with roofs made of oval-shaped brick attest to the splendid nature of the building in its heyday.

The project timeline stated that the first phase would take 16 months to complete and yield 30 MW, while the entire project, which will be in three phases, would be finalized in 36 months.
