How much does the cost of low-voltage energy storage and high-voltage energy storage increase

How much does the cost of low-voltage energy storage and high-voltage energy storage increase

The core differences lie in three cost segments: Equipment: High-voltage access requires step-up transformers, high-voltage switchgear (each unit costs over 50,000 yuan), dedicated metering devices, and relay protection systems, increasing equipment investment by 40%-60% compared to low-voltage solutions; Construction: High-voltage access often necessitates the construction of new substations or expansion of switchyards, involving land costs, civil engineering, and high-voltage cable laying (costing over 200,000 yuan per kilometer), with increased construction complexity leading to longer construction periods; Operation and maintenance: High-voltage systems require certified professionals, with labor costs 30%-50% higher than low-voltage teams.
