Able PAKs provide cost savings at construction sites.
Over 45% reduction in Diesel Generator run time and corresponding fuel savings with Able PAK Battery Power Systems can be realized at construction site offices.
Able PAK 066-066 or Able PAK 100-100 in their Microgrid running modes can deliver cost savings and Scope 1 emission reductions in user cases scenarios such as construction site office complex.
The Results:
- $69,000 fuel saving per year
- $24,000 nett savings in two years
- Less than 2 year payback as a return on investment
- 85T CO2 emission savings per year
The Scenario:
Consider a construction site using a diesel generator (137kVA) to power a temporary office building complex.
The power demand load during daylight activities is significantly different to that at night-time, where security lights, fridges and idle power to computers are still drawing a load.
During the night-time, generators can be severely underloaded with the potential for engine damage being incurred.
Savings are realized by having an Able PAK battery power system, such as a PAK 066-066, in Microgrid Mode, coupled to a smaller generator (Able GEN LG100CS), which provides the load when needed, in a fuel-efficient manner.
Able PAK Microgrid Mode:
This mode is a suitable selection when the total load at any time is less than the selected Able PAK prime power (kW).
In this mode the Able PAK is the primary power supply for the load, and automatically starts and stops the diesel generator only as required to recharge the Able PAK.
The generators start and stops are triggered by a lower and upper State of Charge (SOC) of the Able PAK’s internal Battery Energy Storage System (BESS).
The Microgrid settings to maximise the BESS lifespan are commonly set to SOC 30% as a GEN start, and 85% for GEN stop. These settings are also adjustable to best suit the scenario and circumstances on hand.
The generator then only runs when needed to, at an optimum load setting, which is also a programable function within the Able PAK Energy Management System (EMS).
The selected sizing of the smaller generator is such that it provides a timely recharging of the Able PAK, which can be up to 60kW of continuous power output.
Benefits of the Able PAK Battery Power System:
- Cost savings
- Reduced diesel fuel wastage on oversized generators
- Reduced generator damage from underloading
- Extend generator lifespan and service intervals.
- Reduced Scope 1 CO2 emissions
- Reduced noise pollution
An even further reduction in diesel consumption can be realized if coupled with a roof-top solar PV system … see the Inside Story Example 3 …
