GadgetroniX installed a high-capacity off-grid solar system at Nduta Main Hospital in Tanzania to provide stable, 24/7 electricity for diagnostics, refrigeration, and emergency care. The installation consists of a 77 kWp solar array, 320 kWh of lithium battery storage, and a 100 kW hybrid inverter, reducing the facility's dependence on diesel and the national grid.

The document argues that current RBF programmes often prioritize short-term connection numbers over long-term business viability, creating 'cliff-edge risks' and deterring commercial investors. It proposes a four-pillar approach: aligning impact metrics with commercial viability (e.g., rewarding energy usage and productive-use connections), adjusting disbursement schedules to support capital raises, introducing risk-mitigation instruments for macroeconomic and operational risks, and fostering ecosystem-wide coordination between governments, funders, and investors.

Gham Power installed a 924 kWp rooftop solar PV system for Laxmi Steels in Sunwal, Nepal, completed on 29 September 2024. The project aimed to mitigate frequent power outages and high energy costs associated with grid reliance and diesel generators. Over 25 years, the system is expected to save approximately 540 kilolitres of diesel and reduce carbon emissions by about 2,730 tonnes, while lowering long-term energy costs by 15%. The project received financial support from the Nepal Renewable Energy Programme, UK Aid, and the Alternative Energy Promotion Centre. Additionally, Laxmi Steels is the pilot site for the GRIPS2 project, which integrates a 2 MW / 4 MWh Battery Energy Storage System (BESS) with a 1 MWp solar PV installation and an AI-powered Microgrid Management System.

Gham Power installed an 83.16 kWp rooftop solar PV system for Datahub Nepal in Tilottama, Butwal, to replace a reliance on diesel generators and an unreliable utility grid. The project, completed on 2 July 2024, provides stable daytime power, reducing daytime electricity costs by 68.11%. Over a 25-year period, the system is projected to displace 38 kiloliters of diesel and reduce carbon emissions by 220 tonnes.

KIOCH, a pediatric hospital in Damak, Nepal, installed a 31.6 kWp rooftop solar PV system to address chronic power outages and voltage fluctuations from the grid. The project, implemented by Gham Power with financial support from GRID Alternatives, provides reliable power to 200 hospital beds. Over 25 years, the system is projected to reduce carbon emissions by 70 tons and displace 10.5 kiloliters of diesel fuel.

Gham Power installed a 1.3 MW rooftop solar PV system for Goyal Ispat, a metal factory in Ramgram, Nepal, to address high electricity costs and power quality issues. The system reduces reliance on the 33kV NEA grid and diesel generators, with projected savings of 2–3% on electricity bills in the first year. Over 25 years, the project is expected to replace 452 kiloliters of diesel and avoid 2,970 tonnes of carbon emissions.

Renewvia deployed a 75-connection Okra mesh-grid in Emakalakala, Nigeria, in 2024 to address system-wide blackouts and high costs associated with its existing mini-grids. The mesh-grid pilot achieved 99.1% uptime, reduced capex per connection by approximately 50%, and shortened the payback period by 3 years. These results led Renewvia to shift its strategy toward a pipeline of over 21,000 mesh-grid connections over the next 18 months and the launch of an appliance financing pilot.

The case study argues that productive use of renewable electricity (PURE) requires more than infrastructure, necessitating trust, capacity development, and appropriate financing. In Guatemala, technical assistance and financing for agricultural and commercial equipment helped young women increase revenue by over 30%. In Zambia, a solar-powered agro-processing hub utilizing zero-cost lease agreements for milling entrepreneurs showed a 38% margin based on energy cost savings compared to diesel. These findings suggest that risk-sharing and technical support are essential for scaling productive loads, insights which are being applied to future initiatives in Haiti.

Between January and September 2025, Village Energy installed solar-hybrid and off-grid energy systems in 26 Ugandan health centres to address unreliable grid power and blackouts that compromised oxygen therapy. The systems, ranging from 4.6 kWp to 5.8 kWp, enabled oxygen concentrators to operate up to 20 hours per day without grid input, reducing dependence on costly oxygen cylinders and improving neonatal and paediatric care. The project highlighted the importance of remote monitoring, local staff training, and a two-year maintenance warranty for sustainability. Village Energy has since powered over 100 health centres in Uganda.

A field study in Kenya by Phaesun found that while solar cooling reduces post-harvest losses and increases income, economic viability varies significantly by operational model. Market- and export-oriented operations are highly viable with 3-4 year payback periods, whereas individual smallholder models require 40-100% subsidisation due to high commercial interest rates of 15-20%. The study identifies an "impact capital gap" and suggests that success depends on product value, scale, and the use of blended finance or Cooling-as-a-Service (CaaS) models.

The ARE Energy Access Investment Forum 2026 brought together 1,400 participants from 87 countries to discuss renewable electrification. Key outcomes included the launch of the USD 25m ASCENT Project Preparation Facility by COMESA and a GDP 14m contribution from the UK's FCDO to the Sustainable Energy Fund for Africa in the DRC. The forum highlighted systemic gaps in capital allocation for small African-led firms and the need to shift from supply-led to demand-led skills training for the green transition.

The Community Energy Toolkit (COMET) uses participatory workshops and simulations to help communities in Africa, Asia, and the Pacific plan for the productive use of energy (PUE). By allowing households and micro-enterprises to trial appliances and tariffs, COMET provides developers with demand-side intelligence—such as demand curves and willingness-to-pay—to reduce the risk of under-utilisation and under-recovery of revenues. A deployment in Pos Titom, Malaysia, demonstrated how testing specific enterprise options like grinders and ice-making can create concrete income pathways and decision-ready inputs for implementers. Across 110 communities in six countries, this co-creation approach has been linked to higher early-life utilisation and improved billed revenue.
