Behind the Meter Solar and Battery Storage for AI Data Centers

Behind-the-meter solar and battery energy storage systems (BESS) are redefining how AI data centers secure power. Solar Group designs and delivers grid-independent hybrid energy systems built for the scale, reliability, and cost efficiency that high-performance computing demands.

Why AI Data Centers Need Behind-the-Meter Power Solutions

The demand for AI computing power is growing faster than the electrical grid can support it. Data center operators across the United States face an urgent and compounding challenge: utility interconnection queues are years long, electricity costs are rising, and enterprise tenants require verifiable clean energy. Behind-the-meter solar paired with battery storage is the most scalable and bankable solution available today.
Grid Interconnection Delays Are Stalling Data Center Development
Utility interconnection queues in high-growth markets now stretch 3 to 7 years. For data center developers and operators, every month of delay translates directly into lost compute capacity, deferred revenue, and competitive disadvantage. Behind-the-meter solar and storage systems bypass grid interconnection bottlenecks entirely, allowing projects to reach commercial operation on their own timeline
Rising Commercial Electricity Rates Are Compressing Data Center Margins
Commercial electricity tariffs continue to increase across major data center markets. For facilities consuming tens of megawatts, even a modest rate increase has significant financial consequences. On-site solar generation combined with battery storage locks in a predictable, lower cost of energy and eliminates exposure to volatile utility pricing over the life of the asset.
Grid-Only Power Creates Unacceptable Uptime Risk for AI Workloads
AI inference and training workloads require near-perfect uptime. Grid-dependent facilities inherit the grid’s vulnerability to weather events, transmission failures, and frequency instability. A behind-the-meter hybrid system with battery storage adds a critical layer of energy resilience that protects operations regardless of grid conditions.
Clean Energy Requirements Are Now a Business Requirement for Data Centers
Hyperscalers, enterprise cloud tenants, and institutional capital markets increasingly require data centers to demonstrate verifiable renewable energy use. Operators relying on fossil-fuel power face regulatory exposure, restricted access to green financing, and growing reputational risk. Behind-the-meter solar provides measurable, on-site renewable generation that satisfies ESG commitments and green energy procurement standards.

Behind-the-Meter Solar and BESS: How SolarGroup's System Works

SolarGroup engineers fully integrated, site-controlled power systems combining utility- scale solar photovoltaic (PV) generation with intelligent battery energy storage. The result is a reliable, resilient, and cost-optimized energy supply that operates independently of grid availability and scales to meet the highest data center power demands.
Utility-Scale Solar PV Generation for Data Centers
On-site or adjacent solar arrays are scaled from 20 MW to 200 MW or more, designed around each facility’s physical footprint and power load profile. Bifacial modules on fixed-tilt or single-axis tracker systems maximize energy yield throughout the day. SolarGroup manages site assessment, permitting, engineering, EPC delivery, and long- term performance monitoring for every solar installation.
Battery Energy Storage Systems (BESS) for Data Center Power Resilience
Lithium-ion and lithium iron phosphate (LFP) battery systems are sized to smooth solar generation variability, cover overnight power demand, and eliminate dependence on grid dispatch. Systems scale from 10 MWh to over 500 MWh, with 4 to 8 hour discharge durations and active thermal management. A dedicated team monitors real-time demand kilowatt profiles and fine-tunes battery dispatch to maximize performance and long-term savings.
Intelligent Energy Management Systems (EMS)
An integrated Energy Management System (EMS) orchestrates solar generation, battery storage dispatch, and any grid interaction in real time. Predictive dispatch logic, demand forecasting, and automated kW profile optimization ensure the data center operates at the lowest possible cost with the highest achievable availability. Remote monitoring and reporting are included as standard.
On-Site High-Voltage Switchgear and Power Distribution
Medium-voltage and high-voltage switchgear, inverters, and transformers are specified and engineered to meet data center N+1 or 2N redundancy requirements. All electrical infrastructure is designed for seamless integration with existing or new data center mechanical and electrical systems.
Green Hydrogen Integration for 24/7 Carbon-Free Power (Optional)
For data center operators targeting 24/7 carbon-free energy, behind-the-meter systems can be extended with green hydrogen via electrolyzer and fuel cell integration. Green hydrogen provides long-duration storage that complements solar and BESS, enabling true round-the-clock renewable power delivery without reliance on carbon-emitting backup generation.

Behind-the-Meter Solar and Storage Applications for Data Centers

Hyperscale AI Training and GPU Cluster Campuses

Hyperscale campuses running large language model raining and GPU-intensive workloads require 100 MW or more of uninterrupted, cost-controlled power. SolarGroup delivers purpose-built behind-the-meter energy infrastructure at this scale, with multi-
site portfolio capability and 24/7 clean power delivery.

• 50 MW to 500 MW and above system scale
• Multi-site portfolio development capability
• 24/7 clean energy delivery with verifiable renewable generation

Co-Location and Wholesale Data Center Facilities
Co-location operators can differentiate their offering by providing tenants with verifiable on-site renewable energy, stable long-term power pricing, and guaranteed uptime performance. Behind-the-meter solar and storage directly supports the green energy requirements of enterprise and hyperscaler tenants while improving competitive positioning

• Tenant-level energy metering and renewable reporting
• Structured green energy PPA options for tenants
• Improved Power Usage Effectiveness (PUE) and energy efficiency

Edge and Regional Data Centers in Constrained Markets
Edge compute facilities in markets with constrained or unreliable utility infrastructure benefit significantly from behind-the-meter power. Modular solar and BESS systems enable deployment in high-growth regions ahead of grid buildout, with islanding capability to maintain full operations independent of local grid conditions.
