The flywheel system is capable of delivering up to 4 kwh of energy and providing 200 kw of continuous power.

Flywheel energy storage system cost.

Flywheel energy storage in action in june 2011 the beacon power corporation completed the company s first flywheel energy storage plant in stephentown new york at a cost of 60m. For this report volume was used as a proxy for these metrics. Or total volume and weight of the battery energy storage system bess. Flywheel energy storage systems see fig.

100 000 to 175 000 full depth of discharge cycles battery technologies. Flywheel energy system developed by ccm for energy storage 2. The stored energy is the sum of the kinetic energy of the individual mass elements make up the flywheel. The system would be comprised of ten 500 kw 480v energy storage flywheels with the ability to inject and store up to 5 0 mw of electrical power to guelph hydro s 13 8 kv distribution system.

For bop and c c costs a 5 percent reduction was assumed from 2018 values due to lower planning design and permitting costs achieved through learning with more installations. The long lifetime of the flywheel coupled with high cycle capabilities reduce the cost of storing energy significantly. The plant utilises 200 flywheels spinning at a maximum speed of 16000 rpm to store excess energy and help regulate the supply to the local grid. Cost metrics cost per lifetime kwh of throughput or cost per kw cost per useable kwh power to energy 12 1 12 1 4 1 1 1 1 4 energy delivery 5 minutes 5 minutes 15 minutes 1 hour 4 hours beacon flywheel.

Recyclable and reusable materials have been utilised throughout the system. Total cost of this program was 355 190. A low cost flywheel system with an energy content of 5 0 kwh and 2 2 kw maximum rated power using a steel rotor and economic off the shelf components was designed and investigated. Flywheel energy storage systems market will register a 8 2 cagr in terms of revenue the global market size will reach 177 5 million by 2025 from 129 6 million in 2019.

1 000 to 10 000 full depth of discharge cycles estimated. The flywheel system can respond to power fluctuations in milliseconds. 14 5 are common in many transportation uses including for busses trains cars etc a flywheel accelerates as energy is absorbed and decelerates when energy is delivered back to the system. The apl department of energy low cost flywheel demonstration program was initiated on october 1 1977 and was brought to a successful conclusion on may 30 1979.
