Our Experts
Pearl Street Technologies was founded in 2018 in Pittsburgh, Pennsylvania.
However, the inspiration for our company’s name dates back to 1882, when the first commercial power plant, Pearl Street Station, began powering 400 lamps and 82 Manhattan customers.
Pearl Street Station laid the groundwork for the current U.S. power grid which now has more than 7000 power plants and provides electricity to over 145 million customers across the country.
The team
Since 2018, we have grown
into an agile team of
hand-picked experts who share a common vision for
a renewable future.
We leverage our collective experience across industries and functions to build impactful technologies; it’s the fusion of ideas from different backgrounds that enables everything we do.
