2019 was a big year for Dynapower. Whether it was helping our customers choose the perfect rectifier for their manufacturing process or leading the pack in the growing energy storage industry, Dynapower was more than happy to get the job done effectively and safely.

We are proud to serve customers in nearly every region of the world to make a truly positive impact in people’s lives. This includes reducing our dependency on fossil fuels through the adoption of energy storage systems, Navy magnetic silencing, 20MW chopper systems in mines around the world, ballast water treatment and helping build cars, planes and houses through metal finishing.

That said, here are some top projects from 2019.

Chopper Rectifiers for Copper Mining 


Perhaps one of the biggest projects we delivered on this past year was high-powered chopper rectifier we designed and built for an international mining company in Arizona. In fact, the rectifier was so big it had to be loaded with a crane and shipped on two different tractor trailers with a combined weight of 115,000 pounds!

This massive rectifier will be installed at a copper mine in Arizona and help with the processing of raw copper ore into copper plates. The copper is then used to make everything from building wiring to consumer electronics and electric cars.

Our chopper rectifiers are engineered, designed, manufactured and tested to internationally recognized standards. With nearly 60 years’ experience in high power conversion, our chopper rectifiers are designed to maximize system efficiency and meet the needs of any mining project.

Energy Storage & Battery Backup Power

We’re proud to be a leader in the energy storage market with more than 500MWs of commercial and utility-scale energy storage systems installed worldwide. In 2019, we designed, built and commissioned the nation’s largest behind-the-meter energy storage project at a hotel.

The 4MW/8MWHh system at the Encore Boston Harbor resort in Everett, Massachusetts (5 miles from downtown Boston) will be powered by 2,548 solar panels allowing the resort to lower its electricity bills and power the 33-acre resort with 100% battery backup power in the event of a grid outage.

Along with the resiliency provided by full battery backup power, the resort is also saving money and helping the environment by choosing to pair their energy storage system with solar panels. Go here to learn more about energy storage and its far-reaching applications.

Rectifiers for Ballast Water Treatment 

Invasive aquatic species from ship’s ballast tanks pose a substantial threat to the marine ecosystem. In response to this threat, the “International Convention for the Control and Management of Ship’s Ballast Water and Sediments” was created by the IMO. As such, ship operators are required by law to effectively treat their ballast water prior to discharging it in port.

Dynapower designed, built and certified rectifiers for use in ballast water treatment systems in large shipping vessels. We are adept at developing system specific solutions. In the case of these ballast water treatment rectifiers, we enclosed the units with purpose-built stainless steel. These enclosures were tested and built to withstand extremely harsh salt water conditions. We also installed springs at the base of all the units to mitigate the natural rocking that occurs at sea.

Dynapower has decades of experience ensuring that our products meet and exceed rigorous testing procedures and requirements. We’ve met the regulations of the U.S. Coast Guard and the IMO on numerous occasions when our transformers have been installed on military ships. In other words, we are used to designing purpose-built products that excel in all types of environments–whether it be harsh marine conditions or a stuffy manufacturing facility. 

Marine operations who work with us include: the U.S. Navy, General Electric, Bath Iron Works, General Dynamics Electric Boat and Wartsila. 

Rectifiers for Carbon Free Aluminum

Dynapower refurbished a dozen large rectifiers to help power the development of a new revolutionary process that boasts substantial environmental benefits. This process is the product of a joint venture between Rio Tinto and Alcoa to create aluminum that produces oxygen and eliminates all direct greenhouse gas emissions from the traditional smelting process.


The carbon free smelting process is being supported by Apple, and could help dramatically lower dangerous greenhouse gas emissions on a global level. In Canada—where the technology is being commercialized—this process could eliminate the equivalent of 6.5 million metric tons of greenhouse gas emissions, if fully implemented at existing aluminum smelters in the country. That represents an amount roughly equal to taking nearly 1.8 million light-duty vehicles off the road.

Well, that does it for our top projects from 2019. We look forward to pushing the envelope and embarking on even bigger projects in 2020 that will change our world for the better!
