Introduction & Project Information

Site Setup

The Challenge

The construction site needed to power three large tower cranes and mast climbers, but without direct grid access, it had to primarily rely on two 350 kVA and one 200 kVA conventional diesel generators. This dependency led to various issues, including high carbon emissions, frequent maintenance of the diesel generators, and additional noise pollution and traffic congestion from refueling vehicles. With ESG being a top priority for ESR, these were not ideal.

The Solution

To address these challenges, ESR partnered with Ampd Energy to implement Battery Energy Storage Solutions (ESS), replacing the existing on-site diesel generators with two Enertainers. These were deployed through the nine-month construction period from April to December 2023.

Ampd Energy is driving the global energy transition on construction sites and heavy industries through the creation of state-of-the-art ESS, connectivity software and data science to electrify, connect and optimize the industrial and construction sectors. The Enertainer, a flagship product by Ampd Energy, is a cutting-edge ESS, designed to connect with small grid power and generators, ensuring a consistent and reliable power supply on-site.

Without a grid connection, two 100 kVA diesel generators were used to recharge the Enertainers, downsizing the original two larger (2x 350 kVA and 1x 200 kVA) diesel generators. The deployment of Ampd Enertainers was seamless and required minimal maintenance throughout the project, providing reliable and stable 24/7 power to the equipment onsite.

Results

Since their deployment, ESR has observed substantial benefits and cost savings from using the two Enertainers over a 9-month period compared to traditional diesel generators. The company estimates that these hybrid solutions have collectively reduced carbon emissions by 220 tonnes — equivalent to the average annual electricity consumption of around 120¹ four-room HDB (public housing) apartments in Singapore. Economically, the Enertainers have also cut operating costs by 19%.

During the operation period, the carbon footprint was significantly reduced, and noise pollution was minimized, as the Enertainers are nearly silent, and the diesel generators are only activated automatically for recharging. Productivity was also enhanced – every Enertainer has built-in software, called the Enernet, that is internet-connected 24/7. The Enernet is an advanced and user-friendly online platform which allows project managers to monitor and troubleshoot the ESS remotely in real-time, thereby reducing operational downtime.

¹_{Based on 2018’s grid emission factor of 0.4188 kgCO2/kWh. Average monthly electricity use for a 4-room flat based on EMA figures in 2018 is 353.9 kWh. The average annual electricity consumption of a four-room HDB household is 1.8 tonnes of carbon emissions.}
