TSG, CSI Partner on African Solar Projects

Renewable energy companies The Solar Group (TSG) and Celestial Solar International (CSI) have signed a partnership agreement to deploy utility-scale solar power projects across multiple African countries, covering installations ranging from 50 MW to 550 MW.

The agreement outlines plans for multiple solar farms designed to integrate with national and regional grids and support broader electrification goals across the continent. Work will begin in early 2026, with initial project deployment targeted for completion within one year of commencement.

“This partnership represents a massive leap forward for grid stability in the region,” said Mike Thompson, President, TSG. “By combining TGS’ resources with CSI’s relationships, we are unlocking GW of potential.”

Construction and power delivery arrangements are expected to vary by host country and regulatory environment, with developers negotiating grid interconnection and power purchase frameworks in line with local energy policies.

“CSI’s partnership with TSG enables the delivery of scalable, cost-efficient and secure energy solutions that power residential and commercial sectors, stimulate industrial expansion and support long-term economic development across Africa, while advancing environmental sustainability,” said Paul De-Sosoo, Technical Director, CSI.
