SOL-SAND NEXUS (STARA ZAGORA)

PROJECT SUMMARY


Sol-Sand Nexus is a next-generation 10 MW AI data center located in the energy heart of Bulgaria – Stara Zagora. The project solves the biggest problem of the AI ​​industry in 2026: the huge heat generation and high energy costs. Through innovative integration, we turn waste heat from servers into a revenue-generating asset for city heating.


KEY BENEFITS


Energy efficiency (PUE 1.06): We use liquid cooling, which is 40% more efficient than standard air cooling. (p. 2)
Circular economy: We capture 90% of waste heat and store it in low-cost sand batteries (600°C) for the needs of the city grid. (p. 3)
Own energy: A building-integrated photovoltaic (BIPV) facade provides autonomous power supply for critical infrastructure. (p. 2)
Strategic location: Direct access to the transmission network (ESO) and existing heat supply infrastructure. (p. 11)
FINANCIAL HIGHLIGHTS (Phase 1)
Total investment (CAPEX): €27.2 million (excluding customer IT hardware). (p. 10)
Annual revenue: €13.5 million (AI Colocation + Heat Sales + Carbon credits). (p. 2)
Net profit margin: 35% – 45%. (p. 10)
Payback period: 3.2 years. (p. 10)
Government incentives: Eligible for financing under the Just Transition Fund (up to 50% grant) and a Class A Investor certificate. (p. 2)


INVESTMENT CALL


We are looking for a strategic partner to finalize Phase 1. The project offers a unique combination of exposure to the high-tech AI sector and stable profitability from utilities (Heat-as-a-Service).
