HK Electric Joins Construction Industry to Reduce Emission with "Smart Power for Construction Site" Service

23 Apr 2021

HK Electric has launched a new one-stop service which will help construction sites attain zero carbon emissions by replacing the diesel generator with a timely and adequate grid-powered electricity supply. This will completely avoid the impacts of diesel generators' air and noise pollution on site personnel and the neighbourhood, while reducing the carbon footprint of the construction life-cycle.

The new "Smart Power for Construction Site" service will cover the entire construction life cycle from plan submission, demolition, site formation, foundation to superstructure works. HK Electric will assign a professional team to follow up on all electricity-related matters and provide Smart Power Services on energy efficiency, renewable energy and electric vehicle for further reducing carbon and air pollutant emissions from construction sites.

HK Electric will also explore feasible new technologies for construction site decarbonisation and emissions reduction, such as making use of retired electric vehicle battery as mobile power pack for powering hand tools at construction sites, and deploying battery energy storage system to meet the instant peak power demand of heavy-duty electrical construction equipment.

The Company's Head of Customer Business Development, Mr. Leung Wai-kin, who is overseeing the new service said: "As different construction phases involve different contractors and different construction equipment, it is not uncommon that adequate lead time cannot be allowed for arranging grid-powered supply due to coordination issues. The new service aims to strengthen the engagement and connections with the construction sector, enabling HK Electric to start arranging temporary power supply and planning for permanent supply as early as when developers submit plans to the Buildings Department. HK Electric will facilitate seamless power supply and electricity account arrangement, from meter disconnection and service removal due to demolition, and the provision of a temporary power supply for construction to a permanent supply when the new development is completed."

Grid-powered supply does not produce any air pollutants and noise at construction sites; and this completely avoids the impacts of air and noise pollution from diesel generators on site personnel and the neighbourhood, and helps construction sites attain zero local emission. When compared to using diesel generators, grid-powered supply can reduce up to 60% of carbon emissions and thus reduce the construction life-cycle carbon footprint. Over 50% of energy expenses can also be saved by using grid-powered supply.

HK Electric has taken the lead in promoting electrification during construction of its new gas-fired units at Lamma Power Station. The Company assisted the contractor to estimate electricity demand on the site and the optimal workflow for arranging power supplies and provided power through HK Electric's low-voltage cable for power demand of 3-phase 800A or below; or provided power supply via HK Electric's transformer pillar for power demand above 3-phase 800A. It also complemented the developers with the application of a battery energy storage system to replace diesel generators that provided an ample and stable supply to different work locations on the site.

Senior Manager (Construction Management) of HK Electric, Mr. Thomas Cheong, who is responsible for co-ordination of the Lamma construction site noted that "HK Electric places great emphasis on environmental protection and has introduced various types of mitigation solutions in the construction site. The battery energy storage system is one of the innovative applications that will help overcome the peak demand of heavy-duty electrical construction equipment such as tower cranes, taking us a step closer to becoming a zero-carbon construction site."

Low carbon construction not only protects the environment, it also helps buildings to earn credit points for BEAM Plus certification, demonstrating the organisation's commitment to environmental, social and corporate governance.

Mr. Chan Che-bun, Deputy General Manager (Civil Division) of Paul Y. Engineering, which is the contractor for the Lamma project, pointed out that in recent years the construction industry has vigorously promoted the gradual reduction in the use of diesel generators and diesel-driven devices to reduce or avoid carbon emission during construction and help combat climate change. The battery energy storage system they introduced was developed by a start-up company, AMPD Energy.

Mr. Brandon Ng, CEO and co-founder of AMPD, explained that there are over 10,000 industrial lithium-ion batteries in the battery energy storage system, which continuously charges the system through a low current input. With the characteristics of a long stand-by time in heavy machinery, the stored power is doubled into high output current to meet the peak electricity demand of heavy machineries such as tower crane. He said he is most excited to collaborate with HK Electric and Paul Y. Engineering for a greener Hong Kong.

For typical power demands of 3-phase 400A or below, HK Electric will provide construction sites with stable and reliable electricity supplies via low-voltage cables and weatherproof enclosures to replace temporary diesel generators.  A maximum of two low-voltage cable supply points each of 3-phase can be arranged according to customer's need (i.e. a total capacity of 3-phase 800A).
