• The new agreement with Flo Energy will add at least 11.5 MWp of rooftop solar capacity, with an option to expand to 50 MWp.
• Equinix expects its contracted renewable energy portfolio in Singapore to reach 215 MWp by 2028.
• Its Singapore PPAs are expected to generate about 250,000 MWh of renewable electricity each year.

Equinix expands Singapore renewable energy supply

Equinix has signed its fourth renewable energy power purchase agreement in Singapore, expanding the clean energy supply supporting its growing data center footprint.

The agreement with Flo Energy Singapore will initially add at least 11.5 megawatt-peak of solar capacity. Electricity will come from solar installations on industrial and commercial rooftops across the city-state. The agreement also includes an option to increase capacity to as much as 50 MWp.

It is Equinix’s fourth renewable energy PPA in Singapore in two years. Together, those contracts are expected to lift the company’s renewable energy portfolio in the market to 215 MWp by 2028.

The agreements are expected to generate about 250,000 MWh of electricity annually.

For Singapore, the deal comes as demand for digital infrastructure continues to increase pressure on a power system with limited domestic renewable energy resources. Data centers are particularly energy intensive, making access to lower-carbon electricity a growing operational and regulatory consideration for operators.

Rooftop solar becomes part of data center strategy

Singapore’s dense urban environment limits the availability of land for utility-scale renewable projects. Rooftop solar therefore plays an important role in expanding domestic renewable generation.

The Equinix-Flo agreement will aggregate capacity from industrial and commercial buildings rather than relying on a single large solar site. That structure can help bring additional distributed generation into the electricity system while giving a major corporate buyer access to contracted renewable power.

Flo Energy is Singapore’s largest independent electricity provider. Equinix is also the first customer secured through Flo’s newly launched Data Centre Solutions offering.

The arrangement highlights the growing importance of long-term energy contracting for the data center industry. Operators face rising electricity requirements as cloud computing and artificial intelligence increase demand for processing capacity.

PPAs can provide greater visibility over renewable electricity procurement while supporting the financing and development of new generation assets. For data center operators, they can also strengthen progress toward corporate clean energy commitments without requiring direct ownership of generation infrastructure.

Equinix has been building its Singapore renewable energy portfolio since signing its first PPA in the market with Sembcorp in 2024.

Global PPA portfolio passes 1,490 MW

Including the Flo agreement, Equinix now has more than 1,490 MW of wind and solar PPAs under contract across 11 countries.

That international portfolio gives the company another tool for managing the emissions associated with electricity use across its digital infrastructure network.

Singapore presents a particular challenge. The country has limited land, high energy demand and few options for large-scale domestic renewable generation. At the same time, it wants to retain its role as a major regional digital and financial hub.

Those competing priorities have placed data center energy efficiency and power sourcing firmly within national infrastructure planning.

For corporate buyers, the issue extends beyond renewable procurement. Electricity availability, grid capacity and carbon exposure increasingly affect decisions about where data centers can expand and how future facilities are designed.

What executives and investors should watch

The latest agreement shows how renewable procurement is becoming integrated into data center growth strategies rather than treated as a separate sustainability initiative.

For executives, contracted renewable supply can help manage electricity-related emissions while providing greater certainty around future energy sourcing. Investors will also be watching whether renewable capacity can grow quickly enough to keep pace with soaring digital infrastructure demand.

Singapore’s constrained power market makes that question particularly important.

Equinix’s expanding PPA portfolio demonstrates one approach: combining multiple renewable energy contracts and distributed generation projects to support a rapidly growing electricity load.

As AI and cloud investment accelerates across Asia, access to scalable low-carbon power will increasingly influence both data center economics and national digital infrastructure strategies. Singapore’s experience could provide an important test of how densely populated markets balance those competing demands.
