A handshake in New York
On September 24, during New York Climate Week, the Government of Antigua and Barbuda and Octopus Energy signed a memorandum of understanding at the Global Citizen NOW: Impact Session. Prime Minister Gaston Browne signed alongside Zoisa North-Bond, CEO of Octopus Energy Generation, in a pairing brokered by Global Citizen co-founder Michael Sheldrick.
The agreement is exploratory: the two sides will develop what they call an “implementable plan” covering solar generation, battery storage, electric vehicles and smarter, more flexible demand — potentially linked into a virtual power plant that coordinates rooftop solar, home batteries and EVs to support the national grid.
The first visible step comes quickly. Octopus’s electric vehicle arm will help provide EVs for the Commonwealth Heads of Government Meeting (CHOGM) in St. John’s on November 1–4, 2026 — the 28th CHOGM, and the first hosted by the smallest nation ever to take it on.
Why this matters: the starting point
To understand why this partnership matters, start with where Antigua and Barbuda stands today. Around 93% of the country’s electricity comes from diesel generation. Retail power costs roughly $0.37 per kilowatt-hour — above the Caribbean average — and diesel imports drain more than 10% of GDP (IRENA). The grid itself is fragile: recurring island-wide blackouts, from transmission faults to the collapse of generation at Crabbs that once disrupted school exams, have made reliability as urgent an issue as price.
Against that backdrop, the country’s ambitions are bold — and they predate this deal. Antigua and Barbuda’s revised national climate pledge of September 2021 targets 86% renewable electricity by 2030 and 100% of new car sales electric by 2030. Most of those targets are conditional on international support. The Octopus partnership is best understood as a vehicle for getting there: the capital, technology and know-how that turn a pledge into a plan.
The model: why islands are ideal for the virtual power plant
Here is the idea at the heart of the announcement. Instead of building one big power station, you network thousands of small ones: rooftop solar panels, home batteries and electric vehicles, coordinated by software so they behave like a single, flexible plant. When the sun is strong, the island stores the surplus; when demand spikes in the evening, the network releases it.
For an island nation, the logic is powerful three times over:
- Cost. Every kilowatt-hour of solar displaces imported diesel — fuel the country currently ships in at enormous expense. IRENA modelling suggests the average cost of generating electricity could fall from around $0.15 to $0.105 per kWh with the right upfront investment.
- Resilience. Decentralized assets survive the centralized-grid faults that cause island-wide blackouts. Power lives closer to the people who use it.
- Sovereignty. Keeping energy spending at home instead of sending more than a tenth of GDP abroad for fuel is what energy sovereignty looks like in practice.
And the electric vehicles do double duty: charged on daytime solar, they become rolling batteries — an approach already reflected in the country’s own emissions strategy.
Proof it can work
Antigua and Barbuda would not be the first island to test this model. In Puerto Rico, a virtual power plant built from 70,000 home batteries delivered 48 megawatts during a grid emergency and helped avert a blackout in July 2025; rooftop solar now supplies more than 10% of the territory’s electricity. In Barbados, the Caribbean’s first competitive 60-megawatt utility battery storage tender launched in late 2025, backing a national target of 100% renewable electricity by 2030.
The pattern is consistent: islands are proving grounds for the decentralized grid, because the pain of the old model — expensive, imported, unreliable — is sharpest there.
Eyes open
An honest assessment notes what this agreement is not — yet. It is a memorandum to explore, not a binding deployment: no financing figures, no megawatt targets and no timeline beyond the CHOGM vehicles have been disclosed. The 2030 targets remain conditional on international support. The role of APUA, the national utility holding the exclusive generation, transmission and distribution license, is still to be defined. And a US-backed LNG terminal at Crabbs is advancing in parallel, a reminder that the near-term generation picture still leans on fossil fuels.
None of that diminishes the signal. It defines the work ahead — and work ahead is precisely where partnerships prove their worth.
The ACEN take
At the African & Caribbean Energy Network (ACEN), partnership is not a buzzword; it is one of our five sustainability pillars — building lasting alliances between governments, investors, developers, and communities to deliver transformative clean energy solutions at scale. This announcement is that principle in motion: a government bringing the ambition, a global clean-energy company bringing the technology, and a convenor bringing the two together.
We will be watching how this implementable plan takes shape, and what it teaches the 26 Caribbean states and 54 African nations in our network about turning bold targets into bankable, community-centered projects.
