Diesel generators are commonly used for additional power supply at construction sites today. As a low carbon alternative, Battery Energy Storage System (BESS) has been viewed as a viable option to replace traditional diesel-fuelled construction site equipment. You can gain a better understanding and more knowledge on BESS adoption by our advisory services and General Guideline on BESS Adoption for Construction Sites (PDF).
Role of BESS on Construction Sites
BESS functions as a “Power Amplifier” at construction sites when it is continuously charged, converting a small portion of temporary power supply to provide high output current for equipment with high instantaneous current requirements.
BESS is best suited for following equipment with intermittent loads but high current requirements.
Passenger/Material Hoists
Tower Cranes
Welders
Desanders
Barbenders
Benefits
There are several benefits for adopting BESS on construction sites.
For Developers:
Pursue further opportunities to achieve sustainable development goals, e.g. ESG (Environment, Social and Governance) reporting
Obtain higher Green Building Standards, e.g. potential credits in BEAM PLUS
Enhance your brand image via a greener, cleaner and safer construction site
For Contractors:
Lower operating costs and reduce downtime for refuelling diesel generators
Enjoy quieter operations and more ease obtaining a construction noise permit
Enhance health and safety by eliminating diesel fumes and fire hazards
Note:
If a Battery Energy Storage System (BESS) will be installed for customer self-use, it should be ensured the BESS does not have capability to export power to or back energize the distribution network connected in parallel with the main grid. Reference to Clause 306 of Supply Rules, application for Grid Connection is required for customer’s BESS connected in parallel with the main grid same as for RE power system, this application shall be submitted to CLP for our assessment and agreement at the design stage.
