The Kirby Mill

Powered By NuSTREEM

Since 2014, our office and manufacturing facility have been 100% powered by NuSTREEM turbines.

We invite you to come see them in operation!


About Us

NuSTREEM is an innovative hydro-turbine manufacturer based in Mansfield, CT

We produce modular, standard, digital, continuously-optimizing and easily-maintainable hydro equipment.

Nustreem’s products are based on technological evolutions that make a significant difference to the performance of a long accepted hydro-turbine paradigm. The design methodology we employ eliminates the need for a dam, offers a decentralized generation capability, proposes the ability to harvest energy from existing hydro intensive systems, and provides a low environmental impact, all with a low setup and procurement cost.

Our team believes in our products, not only in their ability to make an economic difference to our customers, but also in their ability to be at least a partial answer to the responsible power-generation needs of our community and our world. We provide an extremely efficient machine to extract clean energy from a renewable resource with minimal impact to the environment.

Not only are we passionate about renewable energy, it gives us great satisfaction to work with small hydropower systems -- whether they be associated with an irrigation district, old mill/old mine, remote community, or some other location, endeavor or project. Regardless of how you refer to the products we provide to your independent hydro plant or run of the river hydropower system, i.e., "water turbine generators," "hydroelectric generators," "hydro generators," or "hydroelectric turbine generators," we have the solution to meet your particular needs.

Uniquely Qualified Design Team

NuSTREEM’s hydropower products were conceived and originally designed by an extraordinarily successful team of machine designers from the aerospace industry. Having been entrenched in designing machines that must work without fail and with super high efficiency, they brought the ultra-modern world to hydro equipment design. On staff mechanical and electrical engineers provide the NuSTREEM team with years of technical & machining experience.

Manufacturability As A Focus

The design team focused on finding US based vendors using common tools and equipment, thereby allowing us to deliver hydroelectric power equipment rapidly and bypass the difficulty caused by having a few rare nondomestic vendors capable of sourcing parts. The entire design was conceived using common parts, common sourcing, common fabrication methods, common assembly equipment and ease of movement for the logistics of delivery.

Long Term Support & Improvement

All the key attributes of our products were designed and conceived within our company, we enjoy continued long term control of the product and its evolution. This eliminates the need to go back to the original designer, or source, if the product is scaled or evolves and adapts to other applications. We also offer rapidly deployed field support service so we can be on the ground, any where in the world to support your needs.
