How flywheel energy storage works
Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the. . The laws of physics (explained briefly in the box below—but you can skip them if you're not interested or you know about them already) tell us that large diameter and heavy wheels store more energy than smaller and lighter wheels, while flywheels that spin faster store much more energy than ones. . Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. Kinetic energy can be described as “energy of motion,” in this case the motion of a spinning mass, called a rotor. [PDF Version]

Why should data centers use Bess?
These benefits make BESS especially valuable for data centers, offering more sustainable power supply, ensuring uptime by enhancing resiliency, offering back-up storage options, and reducing overall energy costs.
What is a Bess & how does it work?
A BESS stores energy from the utility grid and/or renewable energy sources, and supplies energy either back to the grid or to a load. It can be optimized depending on financial, sustainability, and/or resiliency requirements. Each BESS is distributed energy resource (DERs). It's an electrochemical device.
Should data centers embrace Bess technology?
Several key trends are pushing data centers to embrace BESS technology: With vast deployments of solar and wind energy growing greener energy globally, their intermittent supply and low inertia, however, creates grid stability challenges for grid operators.
How much does a Bess system cost?
According to Exenell, the average cost of a typical BESS is $400-$600 kWh. UPS systems can effectively provide back-up power in the case of outages for significantly less cost, but only provide short-term, non-renewable energy. BESS has significantly more reliable energy capacity.
