Asiajin » KDDI To Increase Tribrid Powered Cellphone Base Stations To Reduce CO2 Emissions
Interesting mixed use methodology, where a cellphone basestation is grid backed, but is operated primarily as a power price curve following battery backed power supply with solar assist, the aim being to reduce grid load during peak hours and to reduce the overall grid power consumption costs by going after the cheap power at night, followed by renewable energy assist during the day via solar. Reminds me of that new basestation design (By Ericsson?) those is a modular concrete tube tower with the built-in vertical axis wind turbine. The tube tower is probably a better choice in urban environments due to smaller land footprint ( I don't think you could get a good solar array size on the top cap of the tube), but the tribrid with solar isn't a bad idea in more rural settings, though at that point you might as well throw in a VAWT.
