In 2003 Proton Energy Systems acquired Northern Power Systems for $27 million. Distributed Energy Systems is the holding company and inverstment vehicle for both these companies.

Founded in 1996 in Wallingford, Connecticut, Proton Energy Systems manufactures proton exchange membrane (PEM) industrial hydrogen generators (electrolyzers) and fuel cell-related products. Proton’s PEM-based electrochemical products are employed in hydrogen-generating devices and in regenerative fuel cell systems that function as power generating and energy storage devices. Proton's advanced hydrogen technology is meeting today's industrial hydrogen requirements while providing the models for tomorrow's hydrogen fuel and energy systems. The company holds 11 U.S. patents and has 121 patent filings as of March 31, 2003. Proton’s HOGEN hydrogen generators produce hydrogen from electricity and water, efficiently and without harmful by-products. The company’s UNIGEN regenerative fuel cell systems combine its hydrogen generation technology with a fuel cell power generator for uniquely pollution-free energy storage. Prior to the formation of Distributed Energy Systems Corp., Proton Energy Systems was listed on the NASDAQ and traded under the symbol PRTN.

Established in 1974, Northern Power Systems designs, builds, and installs flexible and reliable on-site and integrated power systems that provide commercial, industrial, and government customers with an invaluable asset: power independence. Northern offers wind, sunlight, hydrogen, biogas, natural gas and oil systems tailored to each customer's unique needs. Northern has installed over 850 systems in 45 countries on all 7 continents.
