Welcome to Innovative Energy Systems

A home backup generator system is a significant long term investment for any homeowner. To ensure that your investment with us is the absolute best, I am personally on site during the entire electrical installation process and I always come back to test and review the operation with you personally after completion. My personal motto, drilled into me from my father is “Do it right or don’t do it at all.” I take this to heart with each and every job and hope to earn your trust and business through our attention to detail and superb knowledge of everything we do.


Regards, Doug Keller Owner

Yesterday I returned home and after entering the house I heard a noise like a breaker was blown. After going upstairs I heard the very low sound of the generator running…Well the power was off and stayed off for several hours…After a nice drive to Hunt Valley we returned home not having to worry about a melt down and to a warm home. What a relief! It is so nice to be able to count on our generator.

Your crew was a pleasure to have around and does fine work. The clean up afterwards was much appreciated…I understand that we will be getting a briefing on the operation and maintenance of the unit…Thanks again for your promptness and attention to detail. We are VERY pleased.

I couldn’t have asked for better service than what was delivered here. The entire crew was very helpful in making sure I understood everything, and went out of their way to go that extra mile.

My experience with IES was outstanding from sales, installation was extremely professional and efficient, and with your responsiveness to the one small problem was prompt and efficient. It was a pleasure doing business with you.

I wanted to take this opportunity to commend your staff members on providing great customer service yesterday… As the president of a residential apartment management company, I have over 200 employees that work out communities whose primary job is to provide customer service to our residents. I plan to share with them this story at our annual meeting to illustrate what customer service is truly about.
Scott Jones, Edgewater, MD
Thank you for your promptness in installing the generator once we had made the decision to do so… The gentlemen who worked on the installation were very respectful and polite. They remained focused on what they had to do… We would feel comfortable recommending you to any of our friends and neighbors.
Justine Fritz, Fallston, MD
As we told you, we are very pleased with the generator installed by IES last May…Dealing with you, and the follow up you have provided, makes us feel sure we chose the right company to supply and install our standby power equipment.
Harry Alexander, Catonsville, MD
Just wanted to let you know that you have two content customers who think of the generator as a security blanket.
Helen Bellafore, Baltimore, MD
When we started looking for a generator, we found IES on the internet and made an appointment with Doug. From our very first meeting we could see that he was running a first class company. Your product and service has been excellent and we appreciate it.
Carol & Richard Hirsch, Pikesville, MD
I enjoyed meeting your installation team. They were nice, hard working and took pride in the completed project.

“In comparison to many companies that “talk” about customer service, you and your company demonstrate true customer service 100% of the time.”

“You guys are the best. You do your job in a unobtrusive manner, with minimal disruption to my schedule. Most importantly I know you will be there when I call. Thanks.”
John Mackey
“Thank heavens for my generator! We have an all electric house and the power fails often with severe weather. It’s a relief to know that when the power goes out, the generator will go on immediately. We would not have survived the derecho of 2012 without the generator because our power was out for seven days!”
Maureen Maguire
“I am very pleased with the thorough work your technician is performing on my Generac. Thank you.”

Electricity is a vital resource we often take for granted. And when a power outage occurs, we’re quickly reminded of how much we rely on electricity throughout our daily life.

A residential standby generator from Innovative Energy Systems (IES) provides the electricity you need to ensure your home and family’s safety, security and protection. Permanently installed outdoors, residential standby generators automatically come on when the electricity fails.

Innovative Energy Systems offers several brands of residential standby generators from leading manufacturers and each have several models and sizes to choose from. Residential standby generators operate using your home’s existing fuel, whether natural gas or LP.

Contact IES for more information or request a free standby generator selection guide. A residential standby generator from Innovative Energy Systems will keep your home and family safe and secure… despite what Mother Nature has in store.
