MiningStore Secures $3.4M Financing from Millennium Infrastructure Fund to Power Dual-Grid Expansion
MiningStore has secured a $3.4 million loan from Millennium Infrastructure Fund, a specialized infrastructure debt fund, to accelerate the buildout of its next 5 MW Bitcoin mining facility with a potential expansion to 10 MW. This financing positions MiningStore to reach 62.5 MW of operational capacity by the end of 2025, a 45% increase in just six months.
The three-year debt facility will fund the construction of a 5 MW hydro-cooled Bitcoin mining site connected to the MISO grid, initially supporting more than 800 miner slots, with engineering flexibility to expand to 10 MW total capacity. The facility is expected to be online by December 1, 2025, creating new hosting opportunities for institutional and individual clients.
Institutional Backing for a Maturing Industry
“We view Bitcoin mining as infrastructure-grade deployment,” said Bill MacNamara, President of Millennium Infrastructure Fund. “Our investment underscores the fund’s commitment to resilient, scalable digital infrastructure.”
The partnership highlights the growing institutionalization of Bitcoin mining, with traditional infrastructure lenders financing projects once considered speculative.
”We are witnessing Bitcoin mining mature from startup venture to institutional infrastructure play,” added JohnPaul Baric, CEO of MiningStore. “Millennium’s involvement signals that world-class financial institutions recognize mining’s role in the digital economy.”
Strategic Advantage: MISO and SPP Grid Access
MiningStore’s dual-grid strategy leverages the strengths of both U.S. power markets:
- 5 MW hydro-cooled capacity in MISO, engineered for maximum performance
- Expansion potential of 5 MW air-cooled capacity in SPP, optimized for cost efficiency
This approach provides operational resilience while aligning with MiningStore’s broader goal of balancing uptime, energy economics, and investor value. By integrating into regulated grids, the facility can also participate in demand-response programs and make use of otherwise wasted or stranded energy, contributing to both profitability and local grid stability.
Scaling With a Proven Operator
With seven facilities already operational and four more coming online by year-end, MiningStore has built a reputation for delivering reliable, institutional-grade hosting capacity. Its product suite, the Managed Mining Program (MMP), Hosting Services, and Remote Hands custom deployments, allows both new entrants and established operators to scale within Bitcoin mining without shouldering the complexity of day-to-day operations.
The new Millennium-backed facility further cements MiningStore’s role as a trusted partner bridging traditional finance and digital infrastructure. Hosting capacity is immediately available for qualified investors and operators seeking to secure scalable, U.S.-based mining infrastructure.
