Can you keep the lights on for 30 days? Manage your grid, generator and solar while surviving Nigeria's energy reality.
Nigeria's Energy Reality, Simulated
The Power Manager game models the actual decisions millions of Nigerian households and businesses make every single day: when to run the generator, how much fuel to stock, whether solar is worth the upfront investment, and how to stretch a tight energy budget across 30 unpredictable days.
Unlike a simple calculator, the simulation includes the random shocks that define Nigerian energy life — pipeline vandalism that dries up fuel stations overnight, NERC tariff hikes that arrive without warning, transformer faults that halve your grid supply, and the occasional good news of a government fuel voucher or grid upgrade.
Understanding NERC Band Classifications
Nigeria's electricity regulator (NERC) introduced performance-based tariffs in 2020, dividing customers into five bands based on how many hours of supply they receive per day:
- Band A — 20+ hours/day. Highest tariff (≈₦209/kWh). Mostly urban, commercial areas.
- Band B — 16–20 hours/day. Second tier tariff. Major residential zones.
- Band C — 12–16 hours/day. The typical Nigerian experience. Standard tariff (≈₦168/kWh).
- Band D — 8–12 hours/day. Lower tariff, significant outages daily.
- Band E — Under 8 hours/day. Lowest tariff (≈₦100/kWh). Rural and underserved areas.
In the game, your chosen difficulty sets your band: Middle Class gets Band A, Average Nigerian gets Band C, and Survivor mode puts you in Band E with just 4 hours of grid power per day.
The Economics of Solar in Nigeria
A 2kW solar kit costs roughly ₦195,000 in the simulation (close to real market prices). At Band C tariffs and typical fuel costs, a household running a 500W load for 6 hours daily on a generator spends approximately ₦3,000–4,000 per week on fuel alone. Solar eliminates that cost entirely during daylight hours.
The simulation awards extra points for low carbon output. Solar eliminates generator emissions entirely and reduces grid-related carbon by providing clean daytime power — making it both economically and environmentally optimal for long-term players.
Real-World Strategies That Score Best
Players who consistently earn Grade A share similar strategies: invest in at least 1kW of solar in the first 10 days, maintain a 15–20 litre fuel reserve for evening backup, run essential-only load during generator hours to stretch fuel, and use battery storage to bridge the gap between solar and grid availability.
The worst outcomes come from over-relying on the generator (fuel costs compound fast), under-investing in storage (blackouts during solar hours are wasted), or running full load all day regardless of source cost.
Generator fuel accounts for over 60% of energy costs in the simulation for non-solar players. A 5kVA generator running 8 hours at standard load consumes 16 litres — at ₦1,400/L that is ₦22,400 per day, or ₦672,000 over 30 days. Solar pays for itself in weeks, not months.
