Welcome to RER Energy Group!

RER Energy Group is a regional leader in the renewable energy industry focusing on solar electric, solar hot water, biodiesel fuel conversion technology, and waste-to-energy systems.

A new energy system is a significant investment. We partner with you to help you choose, and tailor, the right system to maximize your funding incentives. After the installation is complete, we stay in contact to continually evaluate the success of your system over time.

Our approach is to lead clients through a three-phased philosophy:

  1. reduce energy usage through conservation and energy efficiency first;
  2. locally generate with renewable energy and resource recovery when cost effective; and
  3. procure remaining energy needs at optimum rates.

Our goal is to be your long-term strategic business partner and an educational resource as you consider various energy options now and in the future.

We have helped secure over $25 million in grants for our clients and led the development of over 30 megawatts (MW) of solar arrays generating cost-effective energy for more than 100 companies.

We look forward to helping you become more energy efficient.
