Diesel-to-Hybrid Path
- 1. Load audit — rig cycle, generator count, fuel logs.
- 2. Configuration — capacity and inverter sizing against the audit.
- 3. Integration — parallel into the existing rig power network (integration drawing set included).
- 4. Optimization — dispatch tuning plus remote monitoring over the EMS interface.
FAQ
What is workover rig energy storage?
A battery system that parallels the rig’s diesel gensets to shave peaks and recover lowering energy, cutting diesel use — ours run at 180.5/108.2kWh with liquid heating for cold sites.
How much diesel can it save?
Industry studies report 20–30% fuel reduction for hybrid rig power; our field deployments report energy cost down to 8.1% of pure diesel operation.
Can it handle fracking peak loads?
The grid-tied 1,490kWh/1,000kW and off-grid 1,225kWh/1,200kW containers are sized for fracturing fleet load profiles.
Cold-climate operation?
Workover systems ship with liquid heating and insulation options; the platform is rated to -30°C.
