  2. Preparation: The two mobile substations are transported and installed at the selected sites.
  3. Testing: EDC conducts a technical testing phase to validate connection to the existing grid.
  4. September 2026: Testing is successfully completed and the units are officially commissioned.
  5. Implementation: The substations now supply their respective areas, supporting the main grid.

What it actually changes in Siem Reap

  • Fewer daytime outages. Mobile substations relieve the grid during peak hours, when air conditioning and businesses draw the most power.
  • More reliable remote work. For digital nomads, a stable power supply reduces the risk of outages during video calls or project deliveries.
  • Reassured businesses and hotels. Fewer interruptions mean less loss for restaurants, cafes, and accommodations with refrigeration.
  • Better visitor experience. A more stable electrical grid improves comfort during stays and the destination's image.
  • Ripple effect. This type of mobile equipment can be redeployed quickly where demand rises—a positive signal for local investment.

How to avoid trouble

  1. Step 1: Note recurring outage times in your neighborhood to adapt your sensitive activities.
  2. Step 2: Invest in an external battery or UPS for your computer and internet router.
  3. Step 3: Protect your devices with a regulator or surge protector power strip, especially when power returns.
  4. Step 4: Prioritize accommodations and offices equipped with a generator or backup power.
  5. Step 5: Follow EDC announcements and local groups to anticipate scheduled work or maintenance.
  6. Step 6: If you run a business, have a simple continuity plan: emergency lighting, backed-up cash register, monitored cold chain.
  7. Step 7: If problems persist, report them to your landlord or EDC through official channels rather than waiting for spontaneous improvement.

Frequently asked questions

What is a mobile substation?
It is a transportable electrical unit that can be installed quickly to temporarily strengthen or replace grid capacity. It helps support power supply to an area without waiting for fixed infrastructure to be built.
Why are Siem Reap and Kampong Thom affected?
These two provinces are experiencing growing demand linked to tourism, urbanization, and residential use. EDC is strengthening the grid there to limit outages and overloads.
Will this eliminate all outages?
No, but the goal is to reduce them and stabilize supply. Outages can still occur during work, incidents, or exceptional consumption peaks.
Will digital nomads in Siem Reap notice a difference?
Yes, potentially. A more stable power supply reduces interruptions during remote work, video conferences, and data transfers—provided the internet connection keeps up.
How can I follow EDC's next announcements?
Information is relayed by local media such as Cambodianess and EDC's official channels. Expat community groups in Siem Reap also regularly share maintenance notices.
