2026-11-03

The University of Southern Mississippi ( USM ) is seeking bids from qualified manufacturers to supply and install a power generation unit that combines micro - wind turbines and photovoltaic cells to create electricity in a relatively small footprint . In particular , USM is looking for a treeshaped , electricity production system that is capable of producing 7 . 5 kW of electricity in ideal conditions . The system should have 24 micro - wind turbines ( 300 W per microturbine ), as well as 24 photovoltaic cells ( 36W per photovoltaic cell ). I . General Performance Specifications a . The clean hybrid energy generation system ( CHEGS ) shall consist of 24 microwind turbines , 16 of which have affixed photovoltaic units with a surface area of 29 . 5 cm2 b . Each micro - wind turbine and photovoltaic cell shall be rated to produce 300W and 36W of electricity c . The CHEGS unit should be able to generate 7 . 5 kW of electricity d . The CHEGS unit should resemble the shape of a tree that contains 4 metallic trunks / branches II . Requirements a . The following specifications are to ensure that the CHEGS will perform the tasks necessary to satisfy the project ’ s objectives . Any deviation from the following specifications must be explained and justified b . Bidder shall meet or exceed the following capabilities and design specifications : 3 . General Project Requirements I .
