The New Way to Power Telecom Sites
Modern Small Wind Turbines:
A Least-Cost Option for Small Power
Wind for Telecom
Telecom applications require very high
reliability levels for power availability
Good broadcast sites usually have good
wind resources due to their elevation
and exposure
Very high reliability small wind turbines are available.    Typical characteristics:
•  Direct drive alternator
•  Stiff, high strength, blades
•  Heavy structure
Solar and wind are often used together to provide more consistent year-round performance
Wind is often retrofitted to existing PV-only sites to boost performance, particularly in the Winter months
Telecom Systems
Multiple wind turbines often used
Sealed, gel cell, type batteries are
common
Control systems can include alarms
and communications:
•  High / low battery voltage alarm, etc.
•  Remote system monitoring and control
•  Data logging
Shelter heating and cooling can be large part of load
Logistics and ease of installation are important considerations
Projects typically have short lead-times and strict schedules

Does Wind Power Make Sense for You?
With a Load Definition (eg., X kWh/day at 48 VDC) and a Location (eg., Lat / Long, Altitude) BWC can Offer Several Possible Solutions with Budgets
This Allows Potential Customers to Decide Quickly Whether a Hybrid System Makes Sense for a Particular Project or Application
BWC Hybrids are Most Competitive Where the Loads are 2 - 100 kWh/day and the Power Grid is More Than 1/2 Mile Away.
We Would Appreciate an Opportunity to Demonstrate Our Capabilities
