Firming power: capacity you can plan production around.
Firm power is capacity you can plan production around: present when your operation needs it, independent of weather, grid performance, or a single fuel chain. For a mine, firm power is the difference between a production plan and a hope.
Gas engine detail, fuel system
What firming power solves.
- Grid unreliability
- Load shedding, voltage instability, and unplanned outages that stop mills, winders, and smelters.
- Intermittency
- Solar and wind cut costs but cannot carry a 24 hour process load alone.
- Fuel risk
- Diesel-only backup exposes you to price and logistics shocks.
The firming toolkit.
Gas turbines.
Proven firm capacity at scale, suited to larger baseload and mid-merit requirements, with strong performance in hot, high-altitude, and dusty environments.
Reciprocating gas engines, fuel-flexible by design.
Modular engine plants that run on natural gas, LNG, diesel, heavy fuel oil, or in dual-fuel configuration. Fast start, rapid load response, and high part-load efficiency make them the workhorse of firm supply and the natural partner for solar and storage.
Fuel flexibility is the differentiator.
In much of Africa the binding constraint is not generation technology, it is the fuel supply chain. Pipelines are scarce, trucking corridors are long, and a single-fuel plant inherits every weakness of its supply route. We engineer for fuel optionality from day one:
- Dual-fuel and multi-fuel engine configurations that switch supply without stopping production.
- Fuel storage and logistics designed into the plant, not bolted on.
- Commercial structuring that separates your energy price from a single commodity's volatility where the market allows.
The result: a fuel disruption becomes an operating note, not a production loss.
Firm alone, or firm plus hybrid.
Firming plant is the backbone. Most clients then layer solar PV to cut daytime fuel burn and battery storage to replace spinning reserve and smooth transitions. The thermal fleet runs less, the cost per kWh falls, and the firmness stays. Solar & Hybrid Power Battery Energy Storage
For utilities and grid operators.
When a system is short, firm capacity is the difference between managed supply and load shedding. We deliver emergency and firm capacity solutions for utilities and grid operators: contracted megawatts at defined availability, engineered to grid code, with reserve support where the system needs response as much as energy. The engagement routes below apply equally to utility offtakers. Delivery Models
