Indian engineering, procurement and construction (EPC) firm Sterling and Wilson has partnered with French EPC Vergnet to develop a solar-storage and diesel genset hybrid project in Niger, West Africa.

The project is to combine 18.9MWp of solar, an 11.55MWh battery energy storage system and a 6.54MVa diesel generator, to be connected to a substation in the city of Agadez.

The consortium, which also includes local power company SNS Niger, will also be responsible for a two-year O&M contract of the project.

“Hybrid energy solutions is [sic] a huge opportunity as many power generation and distribution companies in places like Africa are moving into renewables,” Deepak Thakur, CEO for hybrid and energy storage at Sterling and Wilson, said.
