Bolivia connects 50 MW second phase of Oruro PV project

Bolivian President Luis Arce this week inaugurated the second phase of the Oruru Photovoltaic Solar Plant. Located 3,700 meters above sea level, the plant is believed to be the world’s highest altitude PV installation.

A 50 MW expansion to the Oruro Photovoltaic Solar Plant, located in central Bolivia, was inaugurated on Wednesday. Bolivian President Luis Arce announced the completion of the project via Twitter.

The Bolivian Ministry of Hydrocarbons and Energy announced a few weeks ago on its website that it intended to complete the construction of the second phase of the 50 MW project.

The plant is located 3,735 meters above sea level in the department of Oruro, 41 kilometers from the city of the same name. The Oruro photovoltaic solar plant was initially 50 MW, tendered by the local government in April 2016. The $54.7 million investment cost was financed by the French Development Agency AFD, the European Union and the Central Bank of Bolivia.

Its execution was carried out by ENDE Corporación, and the Spanish company TSK Electrónica y Electricidad is in charge of the project’s construction. The first stage of the project began construction in August 2018, and it is already in commercial operation, injecting energy to the National Interconnected System – SIN.

In 2019, expansion of the project by another 50 MW was approved. At 100 MW, Oruro is currently the largest PV project in Bolivia. This second phase required an investment of US$54.7 million and the engineering, procurement and construction contract was again awarded to TSK.

Would have been good to have some info about how efficiency correlates with altitude because of less atmospheric absorption and lower ambient temperature.
