Ampd Energy’s Battery System Reduces Air, Noise Pollution at Singapore Construction Sites
Background
City Developments Limited (CDL), a global real estate company in Singapore, has been integrating sustainability into its core business since the 1990s. With a decarbonization plan to achieve Net Zero emissions by 2030, CDL constantly monitors and improves their operations to reach this target.
One key aspect is electricity, which significantly contributes to the carbon footprint at a construction site, typically due to the use of diesel generators for hoisting and other heavy duty construction equipment.
To reduce its carbon footprint, CDL sought a more sustainable option in the form of energy storage systems (ESS) to reduce reliance on diesel generators, starting with the construction of the Irwell Hill Residences condominium in Singapore in 2022. Thereafter, five more projects adopted ESS.

Introduction & Project Information
Site Setup
The Challenge
Diesel generators had been the mainstay for construction sites in Singapore for a long time and many large contractors were uncertain about moving to a new, cleaner technology that enabled them to power up their tower cranes more sustainably.
Diesel generators polluted the air by emitting harmful carbon particles. They also created unwelcome noise that affected those in neighboring buildings.
This was compounded by the fact that the generators were often left running continuously to avoid additional power-up time, which made them inefficient as well.
The Solution
CDL initially deployed an Ampd Enertainer ESS at the Irwell Hill Residences condominium site in 2022 and was completed in March 2024, which helped power two tower cranes. They were used to build the 540-unit luxury residential development, which ran across two towers of 36 floors.
Reliability was one feature that those working on-site quickly noticed. The Enertainer delivered stable power to the site without any disruptions and required minimal maintenance when compared to diesel generators, across the two year construction period. Built for the construction industry, the Enertainer supplied sufficient power on-demand, while amplifying the small electrical current from the grid. This is especially important for the Prefabricated Prefinished Volumetric Component (PPVC) concept, where entire rooms in a building are pre-built off-site and assembled on-site. The Enertainer provided the necessary power for the tower cranes to hoist the heavy loads.
Since the successful deployment at Irwell Hill Residences, CDL has set up the Enertainer ESS at five more developments in Singapore.
Results
With Ampd’s Enertainer ESS at Irwell Hill Residences across the two year project duration, energy costs were 15% lower. On-site, the Entertainer system minimized air pollution significantly and reduced noise pollution by up to 32 times as compared to traditional diesel generators, boosting CDL’s sustainability efforts.
It abated 455 tonnes of CO2 (76% reduction), and saved 221,000 liters of diesel. About 700 manhours were also saved from tasks such as refueling, changing of filters and lubrication.
“We cannot do everything alone, so we spend a lot of time building an ecosystem of innovators like Ampd to help us reach our sustainability goals. No product offers similar features as Ampd, which provides the reliability and stability that the construction industry needs. With more awareness, this green energy effort will scale up over time.”
