The use of hybrid energy (fuel, wind and solar) can contribute to a reduction in both the carbon footprint and fuel consumption of base transceiver stations (BTS). Such solutions of BTSs combining solar panels, fuel generators and small wind turbines (SWT) have been deployed in many regions of the world in recent years. These SWTs typically have power levels ranging from 1.5 to 7.5 kW. Because of the EM impact of megawatt wind turbines (WT) on radars, televisions, GPS, etc., questions have been raised about how locating an SWT in the close vicinity of BTS antennas could degrade transmission quality in radio mobile communications. Radar Cross Section (RCS), Doppler shift and near field coupling of a Representative SWT (RSWT) are analysed to quantify its radio impact on BTS antennas. The results obtained with the RSWT are then compared with those of the 3.5 kW Nheowind-100 realistic model (Nheolis Company) to validate the RSWT design. Corresponding to the worst radio cases, all the models studied are fully metallic.
