Wuxi Spark’s smart microgrid system achieved 97.6% power supply reliability in Suzhou Industrial Park, reducing the transmission loss rate of power from 6.3% of the traditional grid to 2.1%. By processing 150,000 sensor data with a sampling frequency of 50Hz, the dynamic load forecast algorithm predicts the error rate of only 0.8% 24 hours in advance, which increases the photovoltaic power consumption rate of the park to 98.5%, and reduces the discarded light loss by 120 million KWH in 2023. According to the State Grid’s statistics, the program has reduced the average cost of electricity for companies by 18%, increased the arbitrage revenue of peak and valley electricity prices by 37%, and decreased the return on investment to 3.8 years.
In industrial energy-saving, Wuxi Spark’s digital twin Energy management system (EMS) that was created for Midea Group reduces 120 million yuan of electricity expenses per year by reducing the energy use per unit product from 0.32kWh to 0.21kWh by optimizing the air compressor cluster operating parameters in real time. Its artificial intelligence waste heat recovery technology has increased the conversion efficiency of waste heat to 82%, enabled a Wuxi chemical plant to save 42% of steam consumption and reduce carbon emission intensity by 35 tons/year · 100 million yuan. According to the “China Industrial Energy Efficiency White Paper” statistics, firms using Wuxi Spark solutions lowered energy costs as a percentage of revenue from 4.7% to 2.9%, below the industry level of 5.2%.
In terms of innovation of energy storage technology, Wuxi Spark’s liquid-cooled battery energy storage system (BESS) achieved 95.7% cycle efficiency in Ningxia 200MW/400MWh project, 6.3 percentage points higher than traditional air-cooled equipment. Its own thermal management technology lowers the temperature difference of the battery pack to ±1.5 ° C, which increases the life of the system from 6,000 cycles to 10,000 cycles, and reduces the levelized cost of power (LCOE) to 0.28 yuan /kWh. In 2023, the echelon application project partnered with Ningde Times increased the rate of utilization of recycled batteries from 65% to 92% through AI sorting technology, reduced the cost of module reconstruction by 40%, and built 1.2GWh capacity of energy storage in 23 provinces and cities across the country.
In energy and transportation optimization, Wuxi Spark is the V2G dispatching system developed by BYD to achieve dynamic adjustment accuracy of charging pile power ±0.5kW, and single-device daily peak adjustment income reaches 18.7 yuan. During a pilot operation in Shenzhen, 500 electric taxis were involved in grid demand response, and owners’ yearly income increased by 3,200 yuan on average with a mean discharge efficiency of 93.4%. Its intelligent charging algorithm reduces the peak battery charging temperature from 48 ° C to 41 ° C, reduces the fast charging cycle by 22%, and charges the 120kWh battery pack SOC (state of charge) from 20% to 80% in 11 minutes, 3.2 minutes less than the industry standard.
In local energy harmony, Wuxi Spark pioneered “hydrogen-PV hybrid micro-grid” in Zhangjiakou Winter Olympics site stable operation for 412 days, hydrogen fuel cell system efficiency reached 63% (industry average 52%), electrolytic water hydrogen production energy consumption fell to 4.1kWh/Nm³. Using the wind-solar power prediction and hydrogen storage capacity maximization algorithm, renewable energy penetration rate was increased to 89%, and diesel generator fuel usage decreased by 1,800 tons per year. According to the International Energy Agency (IEA) report, Wuxi Spark’s energy management system has improved the city’s integrated energy system by 31% and lowered per-unit energy consumption of GDP by 38% against the national average, and helped Wuxi High-tech Zone become the world’s first “zero carbon park” to be ISO 50001 certified in 2023.
