On a quest to further reduce carbon footprint
EXCELLENCE in Energy Management category award winner PacificLight Power Pte Ltd is a power generation and electricity retailing company that owns and operates Singapore's first LNG-fired power station, which was developed with an investment of S$1.2 billion.
Since its commercial operations in 2014, PacificLight has made numerous efforts to improve its energy efficiency. Over the past two years, it has spent more than S$5 million on plant-enhancement measures, focusing on efficiency and reduction in its carbon footprint.
A notable project involved installing a bypass system which obviates the operation of two fuel gas compressors, resulting in a substantial reduction of 5MW in energy use and monthly savings in excess of S$220,000. This was followed by a recent adoption - for the first time in the local power industry - of large-scale variable speed drives for the feedwater pumps at its power plant on Jurong Island, which cuts electricity consumption by 1.6MW.
Collectively, the energy saved through these projects can power over 10,000 households.
On the green-energy front, PacificLight installed 60KWp solar panels at its power plant early this year, making it one of the few power plants to generate renewable and conventional power at the same time.
"PacificLight is honoured to be selected as one of the winners in this year's EENP Awards. It provides clear affirmation that our efforts in energy management and efficiency are in line with NEA's (National Environment Agency) best practices in energy conservation. Our success is testament to our staff who provide the drive and commitment to implement our efficiency projects," says Yu Tat Ming, chief executive officer, PacificLight.
Mr Yu says that the projects delivered tangible benefits in the form of a reduction of waste and cost savings as well as the sharpening of the team's focus on every aspect of the business.
"What started off as an energy efficiency drive has now transformed into a whole-of-business approach in which the same vigour we have learnt from energy improvement projects is applied across the entire business chain.
"We believe that most companies want to be energy efficient, but are perhaps constrained by a lack of resources or sometimes conservatism. To overcome these constraints, local businesses can start small. Small changes can add up to significant savings and act as a catalyst for the adoption of more significant changes. Taking PacificLight as an example, we encourage business leaders to see energy efficiency not just as a sustainability initiative, but also an enabler of growth in terms of competitiveness."
The company commissioned a 60KW solar panel grid in March 2017. The solar panels are located on the administration building of its power station on Jurong Island and the energy harnessed from the solar panels is used to offset site demand.
"PacificLight has inculcated an energy-saving culture among staff which is included as a key performance indicator (KPI) for all operational staff. Measures that all staff can take on a day-to-day basis include switching off the light when leaving a room, setting a higher temperature for the air-conditioning and shutting down the ventilating system when nobody is in a machine room," says Mr Yu.
Encouraged by its success in achieving energy efficiency, PacificLight says that it has more plans for promoting energy efficiency, including the annual National Sustainable Schools Art Competition, which this year is being held in partnership with the NEA.
"We also offer added services for our customers, such as our PLEASE Programme, which is designed to help customers optimise their energy consumption, reduce costs and increase productivity. Through this programme, our two Singapore Certified Energy Managers (SCEM) perform energy efficiency audits of customers' operations, propose areas for improvement and devise monitoring systems that help customers take control of their energy use," says Mr Yu.
PacificLight's ambition is to also be one of Singapore's leading electricity retailers, providing customers with competitively priced electricity.
It owns and operates an 800 MW combined cycle gas turbine (plant) on Jurong Island, which uses state-of-the-art technology, making it one of the most efficient combined cycle plants currently operating in Singapore.
The company's retail business, known as PacificLight Energy, has a strong focus on customer service, and aims to enhance value for its customers by providing customisable electricity packages that are tailored to meet their individual needs.
