PES is a specialty energy services company that develops and implements innovative energy projects that feature advanced efficiency technologies, solar electric and other renewable energy systems, and combined heating, cooling and power.

The Company’s roots trace back to a Department of Energy funded research project conducted at Princeton University in the late 1970s. The goal of that project was to better understand and more effectively address energy loss in homes.

The internationally acclaimed outcome of that research was the emergence of a “systems approach” to building energy efficiency and the advent of advanced technologies such as infrared thermography, “blower doors” and smoke tracing to diagnose and repair both HVAC and building envelope deficiencies. Technicians trained in these methods and technologies became known as “house doctors”.

In 1981, the researchers created a commercial franchise known as Princeton Energy Partners, and that group went on to change not only the way houses were retrofitted to save energy, but also how they were designed and constructed.

In 1999, Princeton Energy Systems was spun off with the intent of coupling advanced energy efficiency technologies and practices with renewable and clean on-site electricity generation. Whereas Princeton Energy Partners was focused on homes and small buildings, Princeton Energy Systems works with commercial, industrial and institutional customers.

To date, PES has developed, designed and/or installed over 3 MW of photovoltaic (PV) systems for customers in over six states. Members of the PES team have experience developing, building and/or operating over 600 MW of cogeneration. Virtually all of PES’s projects have combined energy efficiency retrofits with on-site generation. With this in mind, the firm remains true to its origins as a “systems” company – we address how to save energy as well as how to produce it on-site.
