Ambergris Caye is getting a serious power upgrade. Belize's five-year Millennium Challenge Corporation (MCC) Compact entered into force on September 18, unlocking a US$125 million grant from the United States — with roughly US$41.7 million earmarked for energy, including a new high-voltage submarine cable from the mainland to San Pedro.
Prime Minister John Briceño, speaking at the launch ceremony in Belize City, confirmed the cable will also serve Caye Caulker, replacing the current link with a modern, larger-capacity connection. The aim: more reliable electricity for the islands, less reliance on costly emergency generation during peak demand, and enough headroom for the cayes' fast-growing tourism industry. Briceño even flagged the upcoming Four Seasons resort on Caye Chapel as the kind of development the improved infrastructure is meant to support.
Anyone who has spent time on Ambergris Caye knows electricity demand there has climbed steeply with the boom in hotels, restaurants and residential builds. A second, stronger connection to the national grid should mean fewer outages and more stable supply — good news if your beach holiday depends on working air conditioning in September heat.
The Compact isn't only about power. It also funds an education project focused on secondary schooling and technical vocational training, part of a broader effort to tackle the two barriers Belize and the MCC identified as drags on growth: education quality and high electricity costs. Belize was selected as eligible for the programme in December 2021, the deal was signed in September 2024, and Belize's government is adding nearly US$55 million on top of the US grant.
For travellers, the practical takeaway is simple: the islands most visitors come to Belize for are getting sturdier infrastructure over the next five years. San Pedro and Caye Caulker already run on tourism — dive shops, reef trips, beach bars — and a reliable grid underpins all of it. If you've been putting off a trip because of stories about flickering power or sweaty nights, the situation should steadily improve. In the meantime, the cayes remain as appealing as ever: world-class barrier reef diving a short boat ride away, golf-cart streets in San Pedro, and Caye Caulker's famously laid-back 'go slow' pace.
