This Earth Day, Delta Electronics and SP Group come together to show how partnerships between technology providers and energy leaders can drive real, measurable sustainability impact. In a world where the green transition is accelerating, success is no longer about isolated innovation—it’s about ecosystems moving in sync.
We speak with Karthik Arunachalam, Delta’s newly appointed ESG Principal Business Architect, and Ooi Chel-Lin, Head of Commercial at SP Mobility, on how their shared commitment to sustainability is translating into on-the-ground action—from fast-charging deployment across Singapore to smarter backend infrastructure.
When EV Innovation Meets ESG Strategy
Q: Chel-Lin, tell us about your focus at SP Mobility.
Ooi Chel-Lin, Head of Commercial at SP Mobility
Chel-Lin: I lead the Commercial team at SP Mobility, where we focus on expanding Singapore’s EV charging network to make it accessible, convenient, and reliable for everyone—from everyday drivers to commercial fleets. Our goal is to build a resilient charging infrastructure that supports Singapore’s broader green ambitions.
Q: Karthik, what’s your background and current focus at Delta?
Karthik Arunachalam, ESG Principal Business Architect
Karthik: I began in clean tech consulting at DNV, working on renewable energy and electricity markets, before moving into industrial energy optimization and sustainability strategy. Before joining Delta, I led the APAC microgrid business at Schneider Electric. Now, I’m focused on scaling Delta’s integrated energy solutions for green buildings, factories, and data centers. We’re developing the One Delta Energy Management Platform and shaping end-to-end decarbonization journeys—Envision, Enable, Execute.
Accelerating EV Adoption and ESG Innovation
Q: Chel-Lin, what are SP’s priorities in supporting EV adoption?
Chel-Lin: We’re aligned with the Singapore Green Plan 2030 and its target of 60,000 charging points. Today, we operate Singapore’s largest fast-charging network, with close to 400 DC points. Our multi-pronged strategy includes:
- Expanding public charging islandwide
- Supporting fleet electrification, especially for heavier vehicles
- Overcoming energy limitations in older buildings with smart load management
- Enhancing backend systems for predictive maintenance and high network uptime
Our mission is simple: make EV charging smarter, faster, and more accessible for all.
Q: Karthik, what are Delta’s current ESG priorities?
Karthik: As a member of Dow Jones Sustainability Indices (DJSI) for 14 consecutive years, Delta already has a well-established ESG framework that drives sustainability excellence across our operations. My current focus is on two fronts: unifying our energy management solutions under the One Delta platform, and co-developing holistic ESG strategies with clients. This includes advisory services, digitization of energy operations, and implementation of decarbonization roadmaps. Our ambition is to be a one-stop ESG solutions partner across industries.
Collaboration in Action: Why Partnerships Matter
Q: Chel-Lin, why are partnerships like the one with Delta critical?
Chel-Lin: Sustainability is not a siloed effort, it’s an ecosystem. Utilities like SP bring deep energy infrastructure know-how, while tech providers like Delta drive innovation in hardware and software. Together, we’re building a network that’s not just reliable, but also scalable and future-ready. Today, Delta chargers make up a majority of our network, helping us maintain high uptime and deploy faster across diverse locations—from residential estates to fleet depots.
Q: Karthik, how does working with SP Group amplify Delta’s sustainability work?
Karthik: SP Group has been instrumental in shaping Singapore’s energy landscape, with efforts in smart grids and advanced metering. Our collaboration opens up opportunities in areas like Vehicle-to-Grid (V2G), Virtual Power Plants (VPPs), and energy storage integration. Through DeltaGrid, Delta Controls, and our broader energy tech stack, we support SP’s Demand Response program and smart city ambitions. There’s also potential to co-develop new applications in AI-driven energy optimization and robotics for infrastructure management.
What Makes a Strong Sustainability Partnership?
Q: Chel-Lin and Karthik, what does a successful partnership look like—and how do we build more?
Chel-Lin: It starts with a shared vision. Even if the path isn’t clear at the start, open dialogue and curiosity can ignite synergies. Trust, adaptability, and a focus on real outcomes—whether it’s faster deployment, better tech, or customer satisfaction—are key to long-term success.
Karthik: A good partnership creates mutual business value while jointly addressing ESG risks. The best examples go beyond transactions:
- When corporates rally suppliers to decarbonize together—like GSK’s renewable energy program.
- When two players co-develop tech to tackle shared challenges—like Bridgestone and Eneos’ tire recycling project.
- When companies share their knowledge—Delta Thailand set up a Net Zero container showroom to share our knowledge with the public on building truly functional net zero industrial spaces.
Ultimately, meaningful partnerships don’t just solve problems—they unlock entirely new opportunities for sustainability and growth.
Towards a Greener, Smarter Singapore
In today’s fast-evolving energy landscape, no single player can drive the transition alone. When utilities and technology providers ignite synergy, they enable smarter infrastructure, faster innovation, and scalable impact. Delta and SP’s collaboration is a strong example of how cross-sector partnerships can accelerate real progress in building a greener, more resilient future.
