Phuket expands the power grid: five new substations and why it matters
Phuket has announced one of the most practical market developments of the year: a power grid expansion with five new substations and more than THB 1 billion in investment. For buyers, this is not just a utility story. For developers, rental operators, and villa owners, it is about comfort, reliability, operating costs, and long-term asset quality. The provincial electricity authority has confirmed a plan to expand network capacity in preparation for stronger demand over the coming years. A new facility in Kathu has already opened, while additional substations are being advanced as part of a broader program. This shows that officials see Phuket’s electricity demand as structural, not temporary. For real estate, that is an important signal. Such projects are usually launched not for today’s load alone, but to support new residential districts, hotels, service businesses, and large developments now entering the market or still under construction. On Phuket, electricity is tied not only to comfort but also to investment performance. Villas with pools, full air conditioning, lifts, security systems, EV charging, and short-term rental operations create a level of demand that weak infrastructure can feel immediately. For a private buyer, this means a lower risk of outages or unstable supply in areas where the network is being upgraded. For an investor, it means more reliable operations, fewer guest complaints, and a lower chance that future tenants will avoid a location because of infrastructure limits. The first beneficiaries are the zones where construction is already intense and where the density of new projects is higher than average. That includes districts continuing to expand with residential complexes, resort properties, hotels, and mixed-use developments. But it is better to look at three factors together: If an area is growing quickly but its utilities lag behind, that often creates a hidden risk for future price growth and rental quality. Buyers should ask developers and agents simple but specific questions: is the project connected to the existing grid or dependent on future capacity, is there backup power, how are common areas powered, are generators included, and how stable is the system during peak season...What happened
