Economics of Methanol+Storage Hybrid Power Supply
| Conventional diesel generator sets | Diesel-fired or methanol generator + energy storage hybrid power station | ||
| Project Scenarios | 50-type oilfield drilling project, the average load of about 1000KW, the highest 2,000KW, with an average monthly consumption of 500,000 kWh | ||
| Power Supply Equipment Specifications | 1,000KW diesel-fired unit | 400KW diesel-fired unit + 500KWh energy storage | 400KW methanol unit + 500KWh energy storage |
| Number of Power Supply Equipment (Units) | 3 | 5+1 | 5+1 |
A. Comparison of equipment procurement modalities
|
Conventional diesel generator sets (procurement) |
Diesel generator + energy storage hybrid power station (procurement) |
Hybrid power plant for methanol generators + energy storage (procurement) |
