• Econet Wireless reported 3.316 million kWh of renewable electricity in FY2025, the highest among the companies examined, although renewables accounted for just 8% of its electricity consumption, compared with Ariston’s 37%.
• Tanganda sourced 20% of its electricity from renewables, compared with Padenga’s 2%, revealing substantial differences in renewable-energy adoption across Zimbabwe’s listed companies.
• Cicada has outlined a 25 MW commercial and industrial solar project pipeline, raising questions about investment returns, electricity cost savings and the financial performance of corporate solar projects.

Harare- Zimbabwe’s corporate renewable-energy disclosures reveal a market in which absolute consumption and dependence on clean electricity follow different patterns. The analysis draws on the companies’ published financial results and annual reports, examining renewable-energy consumption, investment patterns and the extent of corporate reliance on clean electricity.

Econet Wireless reported 3.316 million kilowatt-hours of renewable electricity for FY2025, compared with Tanganda Tea Company’s 1.814 million and Padenga Holdings’ 1.338 million. The figures, compiled from company reports and reported in August 2026, put the telecommunications operator ahead on volume. Its renewable share was 8%, compared with Tanganda’s 20% and Padenga’s 2%. The distinction matters to investors assessing the depth of each company’s energy transition.

Ariston Holdings reported 727,350 kilowatt-hours, with renewable sources accounting for 37% of electricity consumption. CBZ Holdings reported 465,647 kilowatt-hours and a 17% share. Edgars Stores disclosed 415,689 kilowatt-hours and a 32% share. An investor ranking businesses solely by renewable megawatt-hours would favour larger electricity consumers. A ranking by renewable share would produce a substantially different order. Neither measure establishes profitability, avoided diesel consumption or carbon savings without additional operating data.

Telecommunications, agriculture, banking, retail and mining have different load profiles. Mobile networks require continuous power for towers and switching infrastructure. Tea production combines field operations with energy-intensive processing. Retail premises use electricity during trading hours, whereas mines and mineral-processing facilities have substantial round-the-clock demand. A photovoltaic installation has different economic value across these operating schedules because daytime generation, storage needs and backup arrangements vary.

Corporate solar economics can be assessed through the levelised cost of electricity, which divides discounted lifetime project costs by discounted lifetime output. Capital expenditure, financing rates, inverter replacement, maintenance and degradation belong in the numerator. Annual generation, system availability and curtailment determine the denominator. An installation that reduces grid purchases during daylight hours may still require diesel generators or batteries during evening peaks and outages. Company disclosures rarely provide enough information to calculate comparable levelised costs across the sector.

Cicada’s corporate materials describe a 25 MW pipeline of commercial and industrial solar projects. A pipeline is an investment intention and should not be counted as operational capacity. Mining-sector project schedules have also identified solar investments associated with large industrial consumers. Comparing announced megawatts with generated kilowatt-hours is a common analytical error: installed capacity describes potential instantaneous output, whereas energy consumption measures electricity used over a period.

The central financial variable is the price of electricity avoided. An investment model would compare actual grid tariffs, diesel generation costs, solar production and the cost of storing electricity. Payback periods also change with foreign-currency financing terms, import duties, exchange-rate assumptions and equipment life. Where electricity interruptions interrupt production, the value of reliability deserves separate treatment, supported by records of lost operating hours and production volumes.

The disclosed company data establish that renewable electricity has entered mainstream corporate reporting. They do not establish which business earns the highest return on solar capital. A useful next reporting benchmark would disclose annual solar generation, installed capacity, total electricity consumption, project investment, battery capacity and realised savings on a consistent basis. Until then, the clearest comparison is the difference between renewable energy scale and renewable energy intensity.
