Generators for Commercial Businesses

You’re trusted to power the places people work and to do it cost-effectively. Select a distributed generation system to provide power to a facility on a permanent or temporary basis or design a standby power plant. We even offer exhaust emissions for highly regulated emission environments, and utility-grade Cat® paralleling switchgear so you can sell excess electricity to your local grid. Run uninterrupted power and reduce operating expenses with a Cat combined heat and power (CHP) system to simultaneously provide electricity for electrical loads and recover heat to warm facilities.

Our commercial generators offer world-class fuel efficiency and low lifecycle costs. Thompson Power Systems is providing power to meet your demands and to help you cut costs with cogeneration technology. We’re here to keep power production efficient so you can focus on business.

Our Commercial Backup Generators and Permanent Installations

Our company is the regional Caterpillar® dealer, with locations spread across Alabama and northern Florida. If you need a generator or other power system anywhere within our reach, you can count on our team to help you design a solution that meets all your specifications and budget requirements.

We have the largest inventory of commercial generators in the area, including:

  • Diesel generators: Caterpillar manufactures diesel commercial backup generators with maximum output potentials ranging from 6 eKW to 14,040 eKW. These units meet strict emissions standards, and resourceful fuel consumption helps you keep your costs low.
  • Gas generators: Cat gas generator systems are compatible with a range of different fuel sources, including natural gas, biogas, propane, coal gas, and fuel produced using landfill waste. Models with outputs ranging from 50 eKW up to 9,700 eKW are available.
  • Renewable systems: If you are looking for a “green” way to power your business, we can install a Cat Microgrid solar-powered system. These systems use photovoltaic panels that transform sunlight into power and store it in batteries until needed.
  • Mobile generators: With a portable generator, you always have power where you need it. These systems work alone or in parallel to generate power for special events and keep critical systems operating during a power outage. We have 50 Hz and 60 Hz generators in our fleet.

Whether you’re installing a commercial backup generator, need a temporary rental, or looking for a permanent power solution, we will help you design an appropriate system that meets all your needs. As your local source for Caterpillar power systems, we have all the support structures necessary for effective electricity management.
