Mera Gao Power electrifies whole hamlets for the cost of one urban connection
the problem
India's grid skips hamlets too small to justify poles; kerosene is the fallback
background
Uttar Pradesh holds around 200 million mostly rural people, and thousands of hamlets sit too far from the grid — or too small — for extension economics to work. Households light with kerosene: dim, smoky, expensive, and a fire risk; the state utility has no affordable path to them, and 'electrification by 2019' targets measure villages, not the scattered settlements within them.
Since 2010 Mera Gao Power has built, owned and operated solar microgrids for exactly these hamlets: a small solar array plus storage serving a cluster of homes, at a cost the company puts as low as $1,000 per installation. Instead of selling equipment, it sells the service — grids run themselves, switching on automatically each evening to deliver around seven hours of light.
what everyone would do
Extend the grid or donate solar home systems — the grid never reaches hamlets this small, and donated equipment fails when the first battery dies with nobody paid to replace it.
what they saw
The hamlet was never too poor to pay for light — it was too small for infrastructure sized for villages. Shrink the grid to fit the hamlet, own it, and sell evening light against the kerosene budget.
the move
The design choice is radical smallness: not village-scale power but hamlet-scale lighting, sized and priced to what the household already pays for kerosene. Mera Gao owns the asset and recovers costs through regular small payments, so the village buys light without buying hardware; the automated evening-only operation matches the actual demand (light after dark) and keeps the panels and batteries small enough to install for $1,000. A 2017 raise of $2.5 million funded expansion toward thousands more villages.
why it works
Matching capacity to actual demand (a few hours of evening light) collapses the capital cost from utility scale to $1,000, low enough that modest household payments repay it; automation removes the largest operating cost — a technician visiting to switch things on — and owning the asset keeps Mera Gao's incentive aligned with performance: broken equipment is its loss, not the customer's. Pricing against kerosene means the household's alternative is already a recurring cash payment, so switching requires no new budget, just better light for comparable money.
the payoff
1,500+ hamlets and ~15,000 bottom-of-the-pyramid customers served, at ~$1,000 per microgrid installation (operator figures)
where it breaks
The service ceiling is the model's limit: seven hours of light is not refrigeration or irrigation, so customers graduate out when appliances arrive — and when the official grid does reach a hamlet, paying customers defect to the subsidized alternative, stranding the microgrid. Payment collection across thousands of tiny hamlets is operationally fragile, and $1,000-per-installation economics still need concessionary capital, which is why growth tracks donor and impact-finance appetite.
what came after
Mera Gao became the reference model for private hamlet-scale microgrids in India, shaping state microgrid policies and the financing toolkits of development investors who followed.
