The Capstone Hybrid Energy Station (CHES) serves as the main power source in sites where grid power is unavailable. The energy station is flexible and scalable and the output power can be increased or decreased according to demand. Typically, the main power source is provided via solar or wind energy and the engine serves as a back-up, only running when the battery is at a low state of charge.
The Capstone Hybrid Energy Station (CHES) serves as an uninterruptible power supply (UPS) in sites where grid power is available by providing seamless and uninterrupted back-up power in the event of a grid outage.
Operating in this mode, the Capstone Hybrid Energy Station (CHES) serves as a UPS for critical applications in situations where a power failure can result in safety, security or financial risks.
The Capstone Hybrid Energy Station (CHES) can also be used to save money when grid prices spike during peak times. Alternatively, the Capstone Hybrid Energy Station (CHES) can be used to level out a demand profile so the client does not have to pay Utility peak power demand surcharges, i.e. Peak Shaving.
The Capstone Hybrid Energy Station (CHES) can also be used as an energy storage device. Power harnessed from renewable sources or the grid (when this power is available) can be stored and released when needed.
The economic advantage of purchasing cheaper power at night and releasing it during the peak daytime tariff period is complemented by the secondary advantage of having guaranteed back-up power installed on site that is independent of grid issues.
The Capstone Hybrid Energy Station (CHES) serves as the a “Microgrid in a Box” where grid power is unavailable or unreliable. The CHES is flexible and scalable, the output power can be increased or decreased according to demand. The main power source is provided via renewable energy with excess energy stored in a state of the art Lithium Ion Battery Energy Storage System (BESS). The CHES system can be easily integrated with diesel or gas on-site Capstone Microturbine generator systems.
Renewable systems such as wind and solar power are inherently intermittent, as the energy they supply undergoes large instabilities with changes in sun exposure and wind speed. The solution to this problem is the Capstone Hybrid Energy Station (CHES). A CHES is a convenient and efficient way of storing and supplying energy on an as-needed basis, thereby compensating for the instabilities in the wind and solar energy supplies.
The CHES stores the energy that is generated on windy or sunny days, and then supplies that stored energy on days that are calm or cloudy. For this reason, the CHES is vital to the sustainability and continuous development of renewable energy sources. The grid forming capabilities of the CHES allow operation with 100% renewable energy, unlike conventional systems which require dispatchable ‘spinning reserve’ operating continuously.
Modern electricity grids are moving towards high proportions of renewable power generation. This brings new challenges around frequency stability, which the CHES addresses.
