Shenzhen Rail Transit Supporting Storage

Overview

Modular storage supporting construction power for Shenzhen's rail-transit build-out — a 2.5 MW / 10 MWh system that broke ground in May 2026 and completed its 10kV high-voltage grid connection in June, built and commissioned within a single month. Operating under Guangdong's time-of-use industrial tariff, it runs on peak-valley arbitrage, cycling roughly 9,000 kWh a day and avoiding an estimated 1,600 t of CO₂ annually — a green-power benchmark for rail-transit infrastructure.
