Are you tired of skyrocketing electricity bills? What if I told you there’s a smarter way to save money on your energy costs—and it’s already being embraced by thousands of households in Singapore? Here’s the deal: electricity retailers are rolling out innovative residential plans that offer lower rates during off-peak hours, and it’s all thanks to the widespread adoption of smart electricity meters. But here’s where it gets interesting—this isn’t just about saving a few dollars; it’s about reshaping how we consume energy for a more sustainable future.
In Singapore, over 80% of residential homes are now equipped with smart meters, allowing users to track their electricity usage in real-time. As of November 6, SP Group has installed more than 1.3 million of these devices, with plans to complete the nationwide rollout by the end of 2026. These meters aren’t just gadgets—they’re game-changers. Through a simple app, consumers can monitor their half-hourly electricity consumption, identify patterns, and make informed decisions to reduce their energy use. Imagine knowing exactly when and how you’re using power—it’s like having a personal energy coach at your fingertips.
But here’s where it gets controversial: while four out of six major electricity retailers—Geneco, PacificLight Energy, Keppel Electric, and Senoko Energy Supply—offer time-of-use plans, not everyone is convinced this is the best option for them. Some argue that shifting energy-intensive tasks to off-peak hours might disrupt daily routines. Others worry about the complexity of these plans. So, is this a revolutionary way to save money, or just another headache for consumers? Let’s dive deeper.
Take Mr. Chen Jia, a 37-year-old engineer, who switched to Geneco’s time-of-use plan in August. His lifestyle perfectly aligns with the plan’s lower rates from 7 PM to 7 AM. Since his household is empty during the day, most of his energy consumption—cooking, laundry, and air conditioning—happens in the evening. ‘It suits my lifestyle perfectly,’ he says, though he’s kept his savings figures close to his chest. This raises a question: How many of us could benefit from these plans if we just took the time to understand our energy habits?
Currently, most households in Singapore buy electricity from SP Group at regulated tariffs, which are regularly reviewed. However, time-of-use plans offer an alternative by incentivizing off-peak consumption. As Geneco’s CEO, Mr. Lim Han Kwang, explains, ‘The whole intention is to encourage consumers to use more electricity during off-peak periods instead of relying solely on peak hours.’ PacificLight Energy’s general manager, Geraldine Tan, adds that shifting tasks like laundry or charging appliances to off-peak hours not only reduces bills but also helps balance Singapore’s overall electricity demand.
And this is the part most people miss: the global energy crisis in 2022, triggered by Russia’s invasion of Ukraine, sent energy prices soaring worldwide. Dr. David Broadstock, a partner at The Lantau Group, notes that this instability made consumers more cautious about their electricity costs. For those buying from the wholesale market, where prices fluctuate every half-hour based on demand and supply, time-of-use plans offer a way to avoid extreme price swings. It’s not just about saving money—it’s about gaining control in an unpredictable market.
PacificLight Energy has seen a surge in demand for its time-of-use plans, particularly one that offers lower rates from 9 PM to 9 AM with no contract. Sign-ups tripled in 2025 compared to 2024, showing that households are becoming more conscious of their energy usage. But here’s the kicker: Is this trend just a passing fad, or is it the future of energy consumption?
Experts argue that these plans could also help optimize the national grid. As Mr. Lim points out, the grid is built to handle peak demand, even if off-peak usage is low. By shifting some of that peak load to off-peak hours, we could reduce the need for costly infrastructure expansions. This isn’t just about efficiency—it’s about lowering electricity prices for everyone and supporting Singapore’s transition to a sustainable energy system.
Tuas Power’s COO, Michael Wong, adds that spreading out energy use throughout the day creates a more stable grid, reducing the risk of sudden demand surges. Meanwhile, Ms. Tan highlights that time-of-use plans can ease pressure on the grid and facilitate the integration of renewable energy sources, a critical step toward Singapore’s net-zero emissions goal by 2050.
So, here’s the big question: Are you ready to rethink how you use electricity? Time-of-use plans aren’t just about saving money—they’re about being part of a larger movement toward a more sustainable and efficient energy future.
