Singapore’s EV charging network is expanding, but one of the more difficult parts of the transition is increasingly shifting from new developments to older private residential estates whose electrical systems were not designed for sustained EV charging loads.
For condominiums and other high-density properties, installing chargers is not simply a matter of adding hardware. Building managers need to account for available electrical capacity, resident approval, charging behavior, pricing, maintenance, and the ability to expand infrastructure as more residents switch to EVs.
In this TNGlobal Q&A, MNL Solutions’ co-founders say it has now deployed or manages more than 1,000 EV chargers across Singapore, providing a practical view of how these constraints play out at estate level. Co-founder and director Lai Yuan Weng leads the company’s engineering, project execution, and charging infrastructure work, while fellow co-founder and director Sathiyamoorthy Nagarajan oversees technical direction, strategic partnerships, and business growth. Between them, they bring experience spanning electrical infrastructure, construction, safety, operations, and project delivery.
TNGlobal spoke with Lai and Nagarajan about what older condominiums need to become EV-ready, where projects tend to stall, how smart load management can reduce the need for major electrical upgrades, and what Singapore’s experience could mean for other dense Southeast Asian cities.
You recently crossed the 1,000-charger mark. Beyond the milestone itself, what does this tell you about how charging demand is changing in private residential estates?
The milestone reflects how EV charging has shifted from an early-adopter request to a practical estate infrastructure requirement.
In the past, enquiries were usually driven by a small group of residents who already owned EVs. Today, we are seeing more Management Corporation Strata Titles (MCSTs) and property managers take a forward-looking approach, even before demand becomes urgent. Residents are also starting to consider charging access when planning their next vehicle purchase.
That changes the conversation. Charging is increasingly being treated as part of an estate’s long-term infrastructure planning rather than a one-off installation for a handful of users.
Many condominiums were built before EV charging became part of estate planning. What are the most common technical constraints when retrofitting older buildings?
The main constraints are usually available electrical capacity, cable routing, switchboard space, the distance between the main electrical room and the carpark, and whether suitable parking lots are available for charger installation.
Older estates were not designed with EV charging loads in mind, so the challenge is to introduce charging safely without overloading the existing electrical system.
A proper assessment starts with the estate’s current infrastructure. We review spare capacity, the condition of the main switchboard, proposed charger locations, cable routes, and both current and expected charging demand. A Licensed Electrical Worker and the technical team can then determine whether the proposed chargers can operate with smart load management or whether additional electrical provisions are required.
The objective is to minimize disruption and unnecessary upgrading costs while giving the estate room to add more chargers as adoption increases.
How does smart load management help during peak usage periods, and what safeguards are needed to prevent power trips or unreliable charging?
Smart load management controls and distributes charging power according to the building’s available electrical capacity. Instead of allowing every charger to draw maximum power simultaneously, the system dynamically allocates power across charging points based on real-time demand and the limits set for the site.
If multiple vehicles are charging while the building’s overall electricity consumption is high, the system can reduce or redistribute charging power so the total load remains within a safe threshold. This helps prevent overloading and reduces stress on existing electrical infrastructure.
The technology is only one part of the safeguard. Proper load calculations, Licensed Electrical Worker assessments, charger-level monitoring, backend alerts, site-specific power limits, remote diagnostics, and preventive maintenance are all important to keeping the system reliable.
Singapore has made it easier for condominium management corporations to approve EV charger installations. How has that changed the way estates evaluate these projects?
The changes have made discussions more structured. Previously, many estates approached EV charging as a one-off resident request. It is now increasingly evaluated as shared infrastructure that requires governance, resident communication, and long-term operational planning.
MCSTs are looking beyond whether chargers can simply be installed. They are asking who owns the equipment, how pricing is managed, how costs are recovered, how overstaying is controlled, who handles maintenance, and whether the solution can scale as more residents switch to EVs.
We have also seen greater attention to proposal documentation, approval processes, safety compliance, and transparent operating terms. That makes it easier for councils and residents to evaluate a project based on both technical suitability and long-term estate needs.
Government co-funding remains available for qualifying residential charger deployments. Is that creating more urgency among estates, and what still slows projects down?
There is more urgency, particularly as residents increasingly ask whether their estates are EV-ready. Co-funding helps lower the barrier to adoption and gives MCSTs a reason to plan before demand becomes a problem.
Funding, however, does not automatically make a project move quickly. Internal approval is often the biggest constraint. Councils need to align members, address resident concerns, review technical feasibility, understand the commercial model, and schedule the necessary meetings and votes.
Practical questions can also take time to resolve: where chargers should be located, how many lots should initially be allocated, how users will be charged, how overstaying will be handled, and how the system can expand later. Older buildings may require additional technical assessment before those decisions can be made confidently.
EV chargers are shared infrastructure, but they also need a sustainable operating model. How are estates thinking about pricing and long-term economics?
Estates increasingly recognize that EV chargers are not just pieces of equipment in a carpark. They need to be managed fairly and reliably over many years.
For MCSTs and property managers, the main concerns are usually availability, cost recovery, fairness, and resident satisfaction. Different pricing arrangements can be used for residents, visitors, or other user groups. Overstaying penalties can help prevent charging lots from turning into long-term parking spaces, while dynamic load management helps balance demand against the building’s electrical capacity.
From a commercial perspective, many estates want to avoid a large upfront financial burden. Models such as zero-CAPEX deployment and revenue sharing can reduce the initial cost to the management corporation, but estates still need to understand the long-term economics, maintenance responsibilities, pricing controls, and contractual terms before committing.
What have you learned from your first 1,000 chargers about driver behavior and the everyday operational issues building managers need to handle?
Residential charging behavior is quite different from public fast charging. In condominiums, users generally prefer convenient overnight or longer-duration charging. That makes AC charging well suited to many residential environments, provided chargers are reliable and available when residents need them.
Availability is one of the biggest factors affecting satisfaction. Even when an estate has enough charging capacity, frustration can build if vehicles remain in charging lots after charging is complete. Clear policies, app notifications, grace periods, and overstaying penalties can help.
Pricing also needs to be transparent and reasonable because charging becomes part of a resident’s regular routine. At the same time, the operating model has to support maintenance and future expansion.
The broader lesson is that building managers need more than hardware. They need reporting, user support, remote monitoring, preventive maintenance, and an operator that can respond quickly when something goes wrong. The operational layer becomes increasingly important as the number of chargers grows.
How transferable is Singapore’s approach to other dense Southeast Asian cities where older buildings, limited electrical capacity, and shared parking are also common?
Many of the challenges are similar: high-rise living, shared parking, constrained electrical capacity, older buildings, and the need to balance user convenience with infrastructure limitations.
What is transferable is not simply the charger hardware. It is the broader operating model: site assessment, smart load management, backend software, access control, maintenance support, payment systems, and commercial structures that allow property owners to introduce charging without taking on unnecessary risk.
The details will still need to be adapted to local grid conditions, regulations, building practices, and consumer behavior. But Singapore demonstrates that EV charging can be introduced into dense existing developments when the technical, regulatory, and commercial pieces are considered together.
As EV adoption grows across Southeast Asia, cities will need solutions that work within the buildings they already have, not only infrastructure designed into new developments.
