Why a company in Senegal
The group began working in Senegal in 2019, with the Ministry of Health and Social Action. In the first year, one question came up: who repairs equipment installed in a village two years after delivery? The answer was to create a company in the country, with Senegalese technicians, a stock of spare parts and sites in operation. TUMIQUI JAPON SASU exists so that the electricity delivered stays in service.
