How play is plug?
Wind turbines are not plug and play: they interface with the local electrical grid; their foundations interact with the subsoil and obviously are exposed to local ambient conditions.
These interfaces can be straightforward (stable voltage conditions because interconnected to a large central grid, soil with plenty of load-bearing capacity) or cumbersome (weak grids fed by older diesel genset, swampy soils…). Engineers love to design the right solution for every challenge, but this takes time and money.
Together with its partners XANT has developed solutions that enable deployment of XANT turbines with no need for site-specific engineering nor customization (except for your logo on the nacelle and the blades in your favorite color!) This keeps the cost of your project down: you are not only saving engineering hours but thanks to economies of scale, XANT can offer these solutions at a lower cost.
Concrete-less foundations are foundations that are gravity-based : ballast is added to a basket-like structure at the tower base to take the loads. A pre-engineered construction, the concrete-less foundations are shipped in standard 20ft containers and assembled on-site. Minimal subsoil preparation is needed, eliminating the need for heavy equipment. In addition, after the project lifetime the foundation can be completely removed and recycled.
Integrated storage for plug and play
Wind is not intermittent (the wind does not unexpectedly stop blowing) but it is variable: turbulence will cause the wind speed to vary continuously around an average value. With singular turbines there is no spatial distribution, resulting in a smoothened power output. Island power grids powered by diesel gensets pose a real integration challenge when trying to achieve a significant fraction of renewable energy. The intermittency of solar (due to clouds) or power gradients caused by wind speed stochastics, are not easy to handle by the, often antiquated, genset controllers.
The XANT wind turbines with integrated Energy Storage Unit will smoothen the power output of the turbines, avoiding an expensive and complex upgrade of the controllers or the grid infrastructure.
XANT is excited to demonstrate our true plug-and-play solution, for both mechanical and electrical interfaces of the wind turbines in the windiest region of the Philippines.

XANT is a manufacturer of midsize (50…500kW) turbines for the microgrid and off-grid markets. XANT turbines are designed with microgrid applications in mind and a with a special focus on remote areas and harsh operating conditions. They have Just Enough Essential Parts (JEEP!), fit in 40ft containers and can be erected without a crane. For deployment in typhoon-prone areas the turbines can be lowered to the ground, also facilitating the maintenance. XANT turbines have the capability of active power curtailment and can be equipped with integrated energy storage to allow for a high penetration rate.
The extreme simplicity, easy maintenance, silent operation and low cost of ownership make XANT turbines ideally suited for wind power on remote locations and close to the consumer. The XANT product portfolio consist of the XANT M (100kW) and the XANT L (330kW) – commercially available in 2019- platforms. Both turbine types exist in class Ia (average wind speeds up to 10m/s) and class IIIa (7.5m/s) executions; for extremely cold areas ETR (Extended Temperature Range) versions are available.
