Attapeu Province, Lao P.D.R

In 2016, Convalt Energy, a US-based renewable energy company and operator, started developing and as of December 2022, the project is now getting approved up to 1,200 MW Solar Power Project in the Province of Attapeu, Southern Lao PDR in Southeast Asia. This project is in the final stages of development.

Convalt Energy, alongside DigiCollect LLC, an affiliate of Convalt Energy Inc., has performed and completed the First Basic Site Survey of the Lao Solar Project site. The Site Survey shows promising characteristics for the success of the proposed Solar Power Project and provides a foundation for the completed Full Feasibility Study. This Site Survey Report will be distributed to potential EPC Contractors ahead of time in order to fast-track the coming Tendering Process for the construction of the project.

As part of relating the Feasibility Study for this project, the project inception reports and quarterly report were submitted to the Government of Lao PDR on Monday, January 26, 2018. Both reports were submitted in five copies in the Lao language and five copies in the English language as well as one soft copy as per the Government of Lao PDR request.

DigiCollect LLC performed the first detailed Feasibility Study draft for the 1,200 MW Solar Attapeu Project. Feasibility Study Issue No.3 was submitted in mid-November of 2018, four months ahead of the pre-agreed schedule. It has received Interim Approval.

Convalt Energy is currently in the process of implementing the Project Development Agreement and drafting the Concession Agreement prior to the negotiation of the Power Purchase Agreement with Vietnam Electricity (EVN).
