Pay-as-you-go energy loyalty in Africa

The PAYG solar and utility model has unlocked energy access for millions of households across sub-Saharan Africa. The business model challenge — irregular top-up behaviour leading to revenue unpredictability and high default rates — is one that rewards can materially improve.

Companies like M-KOPA, d.light, Greenlight Planet, and a growing cohort of local PAYG operators have connected millions of African households to solar energy through flexible payment models. The technical innovation is significant. The commercial challenge is consistent: customers who top up irregularly are expensive to serve, difficult to underwrite for upgrade products, and likely to default.

The PAYG loyalty opportunity is simple in structure. Reward the customer for topping up on schedule. The reward does not need to be large — it needs to arrive at the right moment and be perceived as genuinely valuable relative to the effort of making the payment.

The top-up behaviour problem

PAYG customers face a competing priorities problem. When income is irregular — as it is for most smallholder farming households or informal sector workers — the solar top-up competes with food, school fees, and transport every week. A customer who values their solar access will still defer a top-up when cash is tight, because the solar unit doesn't immediately fail (it de-rates gradually) and the consequence of missing a payment feels less immediate than hunger.

Rewards change this calculus by adding an immediate positive return to the top-up action. A customer who knows that topping up on time earns a grocery credit or airtime reward has a compound reason to prioritise the payment — they're avoiding service de-rating and earning something simultaneously.

The top-up that earns a reward feels different from the top-up that doesn't. That feeling is the retention mechanism.

Reward mechanics for PAYG energy

• →On-time top-up reward: A small airtime or grocery credit issued every time the customer tops up within their scheduled window. Creates a predictable positive return for punctual payment.
• →Streak rewards: Three consecutive on-time top-ups earns a larger reward. Six consecutive earns more. Creates a gamification dynamic that makes missing a payment feel like losing accumulated progress.
• →Upgrade eligibility rewards: Customers with 12 months of consistent payment become eligible for a larger system or additional product. The upgrade is itself a reward, but the journey rewards along the way keep them engaged.
• →Referral rewards: A gift card for every customer successfully referred. Particularly effective in rural communities where social networks are tight and word-of-mouth drives adoption.

Delivery for off-grid customers

PAYG energy customers are often in areas with limited infrastructure — which is precisely why they're on solar in the first place. Reward delivery must work on 2G and via SMS. USSD redemption is essential for customers without data access. Mobile money transfer is viable in markets with high M-Pesa or MoMo penetration, but airtime is the universal fallback that works everywhere.

Reward format recommendations for PAYG customers

• →Airtime: Universal value, no smartphone required, works everywhere.
• →Grocery credit: High utility value for rural household customers.
• →Cooking gas voucher: Directly relevant for customers transitioning from biomass cooking.
• →Mobile money: For customers with active wallets in M-Pesa or MoMo markets.
