Equinix has executed its fourth renewable solar power purchase agreement in Singapore with Flo Energy to support its local data center portfolio.
Equinix, one of the world’s largest colocation data center operators, has signed a fourth renewable power purchase agreement (PPA) in Singapore with Flo Energy Singapore. Announced in a statement on August 17, the deal marks the US group’s fourth such contract in the city-state since spring 2024. Flo Energy Singapore, a private electricity retailer, describes itself as Singapore’s largest independent supplier. Equinix echoes this characterization, though the claim remains self-declared and is unsupported by any published market-share data.
Rather than relying on a single generation facility, the agreement utilizes a rooftop solar aggregation model that pools output from commercial and industrial installations spread across the country. This approach addresses a structural constraint in Singapore, where limited land availability makes large ground-mounted solar plants virtually unfeasible. The necessity of alternative supply routes is underscored by Singapore’s recent approval of imported solar power from Malaysia and broader regional efforts to secure renewable capacity, including equipment-side expansions such as ABB’s integration of Gamesa Electric. Consequently, scaling local solar output depends on mobilizing already-built surfaces.
The contract includes a guaranteed minimum capacity alongside an extension option that, if fully exercised, would multiply the initial capacity by more than four times. Equinix’s statement does not disclose the value of that starting capacity, nor the maximum capacity that would be reached under a full extension.
This fourth PPA follows three earlier contracts secured through public-sector or major utility-linked counterparties. The first relied on SolarNova, the Housing & Development Board’s (HDB) public program for installing solar panels on government buildings and public housing rooftops. The second covered land and rooftop space belonging to the state-owned development agency JTC on Jurong Island. The third was signed with ESR-TEPCO Singapore AssetCo Alpha, a joint venture between a regional asset manager and Tokyo Electric Power Company Holdings, Japan’s incumbent utility. By adding Flo Energy Singapore, a purely private counterparty, Equinix is actively diversifying its renewable electricity supply channels.
According to Soon Chen Kang, senior research analyst at 451 Research, a unit of S&P Global Market Intelligence, this strategy reflects a Singapore market where energy availability is becoming a strategic issue for the entire data center sector.
Equinix also discloses a cumulative renewable capacity portfolio for its Singapore operations. That figure, however, corresponds to a corporate projection over a two-year horizon rather than a verifiable sum of already-signed firm contractual capacities. The annual production expected from this fourth contract, along with its stated equivalence in number of electric vehicles, are likewise issuer estimates whose calculation methodology is not disclosed in the statement.
The agreement also serves as a commercial showcase for Flo Energy Singapore. Equinix is the first customer of the retailer’s new offering dedicated to data centers, which combines fixed-price contracts, progressive purchases, structured derivative products, renewable energy certificate matching, and power purchase agreements. Flo Holding, the retailer’s parent company, deploys a similar product range in Australia through its local subsidiary. The statement covering this fourth Singapore agreement does not specify the contract’s duration, the start date of deliveries, or its exact financial structure.
