Problem
Regional distribution networks face congestion, voltage instability, and high redispatch costs, while the expansion of physical grid infrastructure is slow and expensive. Existing assets lack real-time flexibility and transparency, limiting the integration of renewable generation.
Solution
Bullfrog offers modular battery energy storage systems (BESS) combined with a digital platform that aggregates and controls distributed storage units as a virtual power plant. The turnkey BESS‑as‑a‑Service model installs VDE‑compliant, 1–10 MW battery modules at existing grid connection points, enabling rapid deployment in months. Through the Bullfrog Connect IoT gateway and an energy management system (EMS), the platform provides real‑time monitoring, AI‑driven optimization of charge‑discharge cycles, and secure, ISO 27001‑certified cyber‑security. The aggregated capacity is marketed on energy markets to generate revenue while supporting grid services such as congestion relief and voltage control, all without compromising battery lifespan.
Target Audience
Primary customers are distribution system operators, municipal utilities, and large industrial or commercial energy consumers seeking to enhance local grid stability and monetize unused connection capacity.
