As EV fleets and customer charging demand continue to outpace local grid capacity, enterprise site operators increasingly face a familiar bottleneck: prolonged waits for transformer upgrades and new utility connections.

At a Riverside site, CA, TeraHive partnered with SolarMax to rapidly deploy their first DC fast‑charging service without requiring any utility upgrades. Using the TeraHive One platform to orchestrate on‑site Battery Energy Storage Systems (BESS), the deployment delivered fast‑charging capability within existing grid limits, bypassing the typical 24‑month utility upgrade timeline.

For this Riverside location, the demand for EV charging was immediate, but the local grid headroom was already at its limit. Peak-hour load spikes pushed existing transformers to their comfort levels, and utility-upgrade estimates threatened to delay site expansion by up to two years. The operator needed a way to add high-power output quickly while remaining grid-friendly and avoiding the risk of nuisance trips or transformer overloads.

To overcome these grid constraints, TeraHive delivered the central intelligence layer through TeraHive One—an energy OS designed to operate and optimize microgrid‑based charging deployments. Working in close collaboration with SolarMax, TeraHive One coordinated grid input, on‑site battery storage, and EV charging in real time, while SolarMax led the engineering and installation of the physical infrastructure to bring the first joint site online without requiring utility upgrades.

• Software-Defined Architecture: TeraHive One acts as the site’s central intelligent and control system, allowing high-capacity BESS and rapid EV dispensers to operate safely and effectively behind constrained grid limits.
• Hardware-Agnostic Integration: Designed for flexibility, TeraHive's open software platform seamlessly integrates with a wide range of multi-vendor hardware. This prevents vendor lock-in and allows operators to choose the best-in-class BESS and chargers for their specific site needs.
• Intelligent Orchestration: The AI-driven platform actively coordinates the grid, BESS, and chargers in real-time. It buffers power to deliver consistent, high-output charging without triggering grid overloads.
• Rapid Commissioning: TeraHive’s streamlined software integration enabled site-controller commissioning in just one day, instantly establishing unified telemetry and remote diagnostics for the entire deployment.

• Speed to Market: ~6‑month deployment vs. ~24 months for typical utility upgrades.
• Reduced CAPEX: By skipping medium-voltage utility work, the operator realized up to 50% savings in upfront infrastructure costs.
• Peak Performance: The system delivers high-power bursts (up to ~240kW) by intelligently combining grid input with stored battery energy

As the site enters its initial phase of operation, this battery‑boosted charging model is expected to deliver the following long‑term operational benefits:
‍

• Reduced Reliance on Utility Timelines: By operating independently of grid upgrades, the site avoids future permitting delays and remains insulated from utility scheduling constraints as charging demand grows.
• Predictable Operating Economics:TeraHive One is expected to continue managing peak loads through intelligent battery dispatch, helping mitigate demand charges and support stable OPEX with a representative 3–5‑year payback outlook
• Scalable, Low‑Touch Operations: Autonomous energy coordination across grid, storage, and chargers reduces ongoing operational effort, while the architecture supports future expansion without introducing new grid bottlenecks—all with centralized, real‑time visibility.
