The Kenyan start-up “PayGo Energy” is addressing the issue of expensive and polluting cooking methods with its prepaid system for cooking gas. In this way, clean cooking gas is also accessible to people with low incomes With PayGo Energy, households avoid the high cost of buying a full gas cylinder by buying only as much gas as they need to cook. Users first register with PayGo Energy for a small fee. Afterwards, they receive a gas cylinder with an intelligent valve (Smart Meter). This will only release as much gas as the user has bought before on a prepaid basis. If their gas quota is exhausted, they must pay by mobile money. The Smart Meter and the gas cylinder of PayGo Energy are also designed to meet the challenges of local infrastructure, especially in informal settlements.
