Soluna & Canaan: Bitcoin Mining Powered by Renewable Energy

Soluna Holdings and Canaan have entered into a hosting agreement to install 20MW of Avalon A15 XP Bitcoin miners at Soluna’s Project Dorothy data centre in Texas.

The collaboration utilises a facility powered by wind energy, underscoring a growing trend of using renewable-powered data centres for energy-intensive operations like bitcoin mining and AI.

It also enhances Soluna's portfolio as a developer of renewable-powered data centres and aids Canaan’s expansion in North America by providing access to cost-effective and dependable infrastructure.

“Soluna is thrilled to develop this new partnership with an industry leader like Canaan,” explains John Belizaire, CEO of Soluna.

"This agreement reflects our shared commitment to delivering high-performance computing solutions powered by renewable energy. With Project Dorothy 2 now online and operational, we're doubling down on our mission to make renewable energy a global superpower.”

Prioritising efficiency

The deployment is scheduled for the first quarter of 2026 and will feature Canaan’s Avalon A15 XP miners, representing approximately one exahash per second (EH/s) of computing power.

These miners are designed for operational efficiency, which aligns with Soluna’s sustainability goals. Their installation at the wind-powered Project Dorothy facility reinforces the focus on renewable energy shared by both companies.

Project Dorothy operates primarily using behind-the-meter wind power, meaning it uses electricity generated on-site. The approach avoids transmitting the power through the main electrical grid.

The facility also maintains a connection to the grid, which helps ensure operational stability and constant uptime – allowing consistent performance while managing costs.

“Our partnership with Soluna is another significant step in advancing our North American self-mining strategy,” says Nangeng Zhang, Chairman and CEO of Canaan. “Each of the partnerships that we have entered into brings a new dimension to our efforts to expand within the region, and we are excited to work with Soluna and utilise their cutting-edge data centre.”

Nangeng continues: “The site primarily runs on behind-the-meter wind power but can also draw from the grid to ensure very high uptime. This is a unique advantage that combines reliable operations with compelling cost efficiency.

“Coupling our efficient and resilient Avalon A15 XP miners with Soluna's infrastructure should be a win for both companies.”

Monetising green energy with digital infrastructure

Project Dorothy is a component of Soluna’s larger strategy to build out its renewable-powered digital infrastructure. The company is currently developing over 2.8GW of renewable computing projects.

Each project is designed to monetise surplus clean energy by providing power for high-compute operations such as bitcoin mining and AI.

By matching renewable energy generation with computational demand, Soluna addresses two distinct challenges.

The first is the curtailment of renewable energy, a situation where excess power is generated but cannot be utilised by the grid.

The second is the increasing need for scalable infrastructure capable of hosting energy-intensive digital processes. The Texas facility serves as a practical example of how renewable-powered data centres can meet the computational demands of advanced technologies while supporting sustainability targets.

Strategic partnership for North American expansion

For Soluna, this collaboration with Canaan is an important step in scaling its renewable-powered business model. With its Project Dorothy 2 site now operational, Soluna is using partnerships with technology firms as a central part of its strategy to monetise its growing capacity pipeline.

The agreement also supports Canaan’s goal of strengthening its presence in North America, where demand for efficient blockchain infrastructure is growing.

By partnering with renewable energy operators like Soluna, Canaan secures access to sustainable and cost-effective locations for deploying its advanced hardware.

Both organisations share an objective to demonstrate that energy-intensive digital workloads can be supported by renewable energy at a significant scale.

Their joint effort illustrates how industry partnerships can lead to the development of efficient and environmentally conscious infrastructure.

Through Project Dorothy, Soluna and Canaan show that high-performance computing and sustainability can be compatible objectives, setting a precedent for future digital infrastructure powered by clean energy.
