The Opportunity

Problem

Zimbabwean manufacturers face up to 18-hour daily power outages from ZESA load shedding, halting production and forcing reliance on costly diesel generators.

Solution

GenSaver logs generator runtime, fuel usage, and maintenance to predict refills and optimize schedules during outages. It alerts on cheapest local fuel deals and suggests efficient run times to minimize expenses. Track ROI with automated reports showing savings vs diesel-only baseline.

Target Audience
